RESEARCH REPORTING SERIES
Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been grouped into nine series. These nine broad cate-
gories were established to facilitate further development and application of en-
vironmental technology. Elimination of traditional grouping was consciously
planned to foster technology transfer and a maximum interface in related fields.
The nine series are:
1. Environmental Health Effects Research
2. Environmental Protection Technology
3. Ecological Research
4. Environmental Monitoring
5. Socioeconomic Environmental Studies
6. Scientific and Technical Assessment Reports (STAR)
7. Interagency Energy-Environment Research and Development
8. "Special" Reports
9. Miscellaneous Reports
This report has been assigned to the ENVIRONMENTAL PROTECTION TECH-
NOLOGY series. This series describes research performed to develop and dem-
onstrate instrumentation, equipment, and methodology to repair or prevent en-
vironmental degradation from point and non-point sources of pollution. This work
provides the new or improved technology required for the control and treatment
of pollution sources to meet environmental quality standards.

FOREWORD
The Environmental Protection Agency was created because of increas-
ing public and government concern about the dangers of pollution to the
health and welfare of the American people. Noxious air, foul water, and
spoiled land are tragic testimony to the deterioration of our natural
environment. The complexity of that environment and the interplay bet-
ween its components require a concentrated and integrated attack on the
problem.
Research and development is that necessary first step in problem
solution and it involves defining the problem, measuring its impact,
and searching for solutions. The Municipal Environmental Research
Laboratory develops new and improved technology and systems for the
preservation and treatment of public drinking water supplies, and to
minimize the adverse economic, social, health, and aesthetic effects of
pollution. This publication is one of the products of that research; a
most vital communications link between the researcher and the user
community.
The St. Louis-Union Electric-EPA refuse fuel project was the
first demonstration of the use of solid waste as a supplementary fuel
in power plant boilers for generating electricity. In addition to the
demonstrations, research tasks were conducted to evaluate the processing
plant and the power plant operations. This report presents the results
of the processing plant evaluations. It provides data on plant material
flows and operating parameters, plant operating costs, characteristics
of plant material flows, and emissions from various processing operations,
A separate report will provide similar information on the evaluations
conducted at the power plant which burned the refuse derived fuel.

ABSTRACT
This report presents the results of processing plant evaluations
of the St. Louis-Union Electric Refuse Fuel Project, including equipment
and facilities as well as assessment of environmental emissions at both
the processing and the power plants. Data on plant material flows and
operating parameters, plant operating costs, characteristics of plant
material flows, and emisssions from various processing operations were
obtained during a testing program encompassing 53 calendar weeks.
Refuse derived fuel (RDF) is the major product (80.6% by weight)
of the refuse processing plant, the other being ferrous metal scrap, a
marketable by-product. Average operating costs for the entire evalua-
tion period were $8.26/Mg ($7.49/ton). The average overall processing
rate for the period was 168 Mg/8-hr day (185.5 tons/8-hr day) at 31.0
Mg/hr (34.2 tons/hr).
Future plants using an air classification system of the type used
at the St. Louis demonstration plant will need an emissions control
device for particulates from the large de-entrainment cyclone. Also
in the air exhaust from the cyclone were total counts of bacteria and
viruses several times higher than those of suburban ambient air. No water
effluent or noise exposure problems were encountered, although landfill
leachate mixed with ground water could result in contamination, given
low dilution rates.
This report was submitted in fulfillment of Contract No. 68-02-1324
and Contract No. 68-02-1871 by Midwest Research Institute under the
sponsorship of the U.S. Environmental Protection Agency. This report
covers the period September 23, 1974, to September 30, 1975.

ACKNOWLEDGEMENTS
This report was prepared for the Environmental Protection Agency under
Contracts Nos. 68-02-1324 and 68-02-1871. It describes the work carried out
by Midwest Research Institute (MRI) at the St. Louis Refuse Processing Plant
for the period of September 23, 1974, through September 30, 1975.
Mr. Doug Fiscus, Mr. Paul Gorman, Mr. M. P. Schrag, and Dr. L. J. Shannon
were the principal authors of this report. Many other MRI personnel assisted in
compilation and analysis of the data. Actual equipment tests and refuse sampling
were carried out at the processing plant by Mr. Steve Howard, Mr. Lynn Cook, and
Mr. Edward Gonzalez, under the direction of Mr. Doug Fiscus (MRI Field Manager).
Most of the laboratory analyses of the refuse samples were done by the Research
900 Laboratories of the Ralston Purina Company in St. Louis, Missouri. The con-
duct of this test and evaluation program at the processing plant would not have
been possible without the excellent cooperation and assistance provided by
Mr. Wayne Sutterfield (formerly Refuse Commissioner, now Traffic and Transpor-
tation Administrator, City of St. Louis), Mr. Jim Shea (Refuse Commissioner,
City of St. Louis), and the Refuse Processing Plant staff, especially Mr. John
Molitor, Mr. Nick Yung, and Mr. Roger Chadwick.

INTRODUCTION
The St. Louis Union Electric System is the first demonstration plant in
the U,S, to process raw municipal waste for use as a supplementary fuel in power
plant boilers. In addition to producing a fuel, ferrous metals are recovered
from the waste for use as a scrap charge in steel production. Two separate fa-
cilities comprise the system—a processing plant operated by the City of St.
Louis and two identical boilers (Combustion Engineering, 125 Mw, tangentially
fired), which were modified to fire shredded, air classified refuse along with
pulverized coal at the Union Electric Company's Meramec Plant near St. Louis.
This demonstration facility had been in operation for over 2 years and had
shown that such a system is a workable method for utilizing processed municipal
refuse as a supplementary fuel, and that a saleable by-product (ferrous metal
scrap) can also be recovered. Since the St. Louis facility has been in operation,
several similar facilities have been placed under construction, or are being
planned in other cities. Because of that and the growing interest in this resource
recovery method, EPA expanded their demonstration program at St. Louis to permit a
more detailed study of the performance and characteristics of the operation includ-
ing environmental aspects.
EPA contracted with MRI to conduct a test and evaluation program at the St.
Louis demonstration facility. This program included equipment and facilities
evaluations and environmental assessments at both the refuse processing plant
operated by the City of St. Louis and the refuse firing facility operated by
Union Electric Company's Meramec Plant.
This report presents the results of test and evaluation activity at the
processing plant during the 1-year (53-week) period of September 23, 1974,
through September 30, 1975. In order, the report presents (a) approach, (b)
evaluation of facilities, (c) plant, material flow and characterization, and
(d) environmental evaluation.
-------
CONCLUSIONS AND RECOMMENDATIONS
RDF has approximately 42% the heating value and 2.7 times the ash
content of Illinois Orient 6 coal. However, the refuse fuel has only
approximately 12% the sulfur content and 35% the nitrogen content of the
coal. The ferrous metal recovered by the processing plant is a market-
able by-product that was utilized as part of the scrap charge at a near-
by steel mill. On the average by weight, RDF represents 80.6% and re-
covered ferrous metal 4.5% of the processed raw refuse. The plant reject
material which was landfilled had very low energy content. There is
little value in trying to recycle the rejects to recover energy.
As would be expected, operating costs per megagram (Mg) of RDF
produced increase rapidly when the plant is operated below its design
capacity. Total monthly operating costs for the refuse processing plant
plus the receiving facility ranged from $4.45 to $57.99/Mg ($4.04 to
$52.6/ton) represented that month when the plant was operated near
design capacity and no unscheduled shutdowns occurred. Average total
operating costs for the entire 1-year evaluation period were $8.26/Mg
($7.49/ton).
ASSESSMENT OF ENVIRONMENTAL PROBLEMS
Future plants using an air classification system of the type used
at the St. Louis demonstration plant will need an air emission control
device to control particulate emissions from the large de-entrainment c
cyclone. Particulate concentration in the air exhaust to atomosphere
from this cyclone averaged 0.57 g/Nm3 (0.25 grains/ft3). Also total
counts of bacteria and viruses at levels several times higher than that
found in suburban ambient air were found in this air exhaust.
The quantity of water effluent from washdown of the plant is small,
and no water pollution problem exists.
A sound survey of the plant revealed several locations above 90 dBA,
the maximum allowable level for continuous 8-hr exposure. However, no
worker is present at these locations for 8 hr or more. Therefore, no
worker noise exposure problems presently exist.
An analysis of laboratory-produced leachate from the processing plant
products that might be landfilled (RDF and magentic belt rejects) was
performed . The results of this analysis indicated that if leachate from a
landfill were to be mixed with groundwater, contamination could result
if the dilution rate of leachate to groundwater were not high enough.
-------
PROCESSING PLANT OPERATIONS
The overall processing rate average for the entire test period
was 168 Mg/8-hr day (185.5 tons/8-hr day) at 31.0 Mg/hr (34.2 tons/hr).
In the first 2 weeks of the test period, the plant was operated at
maximum capacity of 272 Mg/8-hr day (300 tons/8-hr day), demonstrating
that the plant was capable of sustaining this rate at least over a 2-
week period. The maximum processing rate achieved for a 1-day average
was 45.8 Mg/hr (50 tons/hr).
Two major equipment breakdowns occurred at the processing plant,
breakage of a drag chain conveyor to the air classifier, and failure
of the hammermill electrical system. Several plant shutdowns occurred
due to equipment maintenance outages at the Union Electric power plant,
and once for repair of an electrical substation serving the refuse
processing plant. As is the case with any facility having mechanical equip-
ment, planned shutdowns also occurred to perform normal maintenance.
The plant material balance by weight showed that plant output aver-
aged 7.6% less than the plant input. Scale error and moisture and par-
ticulate loss from the air classifier and dust collection system were
identified to account for 1.6% loss, leaving a 6% unaccounted error. It
is theorized that moisture loss from the hammermill is the major cause
of this material loss.
-------
APPROACH
The test and evaluation program conducted by MRI at the processing plant
included three primary areas o£ investigation:
1. Equipment and facilities evaluation;
2. Characterization of plant flow streams; and
3. Environmental evaluations.
The specific items included in the program are detailed in Table 1 and
served as the basis for development of the test schedules and procedures. The
program consisted of sampling and analysis and equipment and facilities evalu-
ation for the 53-week test period according to the test program shown below.

-------
Even though refuse samples were not taken during weeks 6, 7, 12, 33, 34,
35, and 39, plant material flows, man-hours, and costs were recorded.
Recording of plant downtime, maintenance requirements, operating costs,
etc*, was performed and compiled on a monthly basis for the full year,
A flow diagram of the refuse processing plant and the material sampling
locations are shown in Figure 1. Figure 2 shows the RDF-receiving facility lo-
cated 31 km (19 miles) away at the power plant. No samples were taken at the
receiving facility, because only RDF was handled at this facility and RDF had
been previously sampled at the processing plant. However, its equipment descrip-
tion was recorded, and the cost of its operation is included in the cost analy-
sis of the refuse plant.
The material sampling and analyses performed during the test period are
shown in Tables 2 through 4. Samples of the material flow streams were taken
using a 9.5-liter (10-qt) container. This container was manually passed through
the material flow streams in free fall as they were being discharged from a con-
veyor belt. By sampling the material in free fall, a representative sample was
obtained. Either two or four daily samples were taken to form a daily or weekly
composite sample as shown in Tables 2 through 4. The daily samples were equally
spaced throughout the day. For example, if the plant operated 4 hr, and the sam-
pling program specified four samples per day, then a sample was taken once per
hour.
The daily samples were stored in a 75-liter (20-gal.) sealed container.
Samples for analysis were prepared by first manually well mixing the composite
samples using a small spade, and then extracting two portions, A 9-liter (0.3-
ft ) portion was sent to a laboratory for determination of all items except
bulk density and hand pick composition, A 20-liter (0.7-ft3) portion was used
for bulk density. The material was poured into a 17,56-liter (0.62-ft^) round
container in a careful manner so as to avoid packing, and then struck off to
insure a level fill. The net weight of this container was determined and the
bulk density calculated. A small portion of this material was then utilized
for the hand picked composition.
Composition analysis was performed using only a hand-held magnet to ex-
tract ferrous metal, several tongs, and a 6-ram (0.25-in.) square mesh screen
to aid in separation of the sample into its various components.

EVALUATION OF FACILITIES
All the refuse sample analyses and plant operating data collected were
compiled and analyzed with the aim of meeting the objectives of the equipment
and facilities evaluation as listed previously in Table 1. The results have
been summarized and are presented in the following sections of this report.
Tabulations of associated data are presented in the four appendices as follows:
* Appendix A - Description of Plant Equipment and Plant Costs;
* Appendix B - Characterization of Plant Input/Output Streams;
* Appendix C - Environmental Test Procedures and Data; and
* Appendix D - Statistical Evaluation of Process Stream Samples.
PLANT OPERATIONS
A daily log of plant production rates and plant activity during the test
period is presented in Appendix Table A-9. A weekly summary of the daily plant
activity is contained in the following Table 5. Because the bulk of the plant
equipment is located outside, ambient temperature and humidity were recorded
(Figure 3) for each test day to show the environment in which the equipment
was operating.
Of the 53 weeks comprising the test period, plant production of refuse
derived fuel (RDF) occurred during 45 weeks, leaving a balance of 8 weeks with
no production because of the following reasons.

Production did not occur on every day of every week of production. During
the total test period there were 259 days available for processing. Processing
operations were actually conducted for 158 days, yielding a 6170 use factor for
the processing plant. The reasons for no processing operations for individual
days are shown in Appendix Table A-9.
The average weekly plant processing rates summarized in Table 5 have been
plotted on Figure 4 to depict fluctuations. The processing rates are based on
actual time the plant operated (i.e., not including downtime).
Processing rate appears to decrease with a decrease in daily tonnage, al-
though statistical analysis of the data yielded only a 43% correlation between
megagrams per hour and megagrams per day. Processing rate is controlled by an
operator's visual observation of the hammermill motor current via an ammeter.
The operator's objective is to keep the hammermill operating as close as possi-
ble to the maximum motor current. Feed rate to the hammermill is controlled by
a variable speed drive on the raw refuse receiving belt conveyor. The hammermill
has a nominal capacity of 41 Mg/hr (45 tons/hr). The daily rates varied from 44
to 112% of this design rate, with the average being 76%. Any individual day may
have a high processing rate; however, due to the variabilities of incoming raw
refuse and the human operator's alertness, it would be difficult to greatly im-
prove the average processing rate over a long time span. Therefore the tons of
refuse processed are primarily a function of the number of hours the plant op-
erates.
PLANT COSTS
Cost data for the 12 months of October 1974 through September 1975 and capi-
tal costs have been collected and summarized in Table 6. A detailed breakdown of
this cost summary is shown in Appendix Tables A-6 through A-8. For evaluation
purposes, the total refuse processing plant was categorized into two separate
cost centers: the processing facility and the receiving facility.

-------
The processing plant cost center includes all operations necessary to pro-
duce and store RDF. It includes as vehicles the front end loader used to push
the raw refuse onto the receiving belt, dump trucks to haul away the Fe metal
by-product and reject material, and the plant automobile and pickup truck.
Also, it includes the storage bin and packer load-out station. Not included
are the trucks used to transport RDF to the power plant.
The receiving facility cost center includes the transport trucks used to
deliver RDF to the power plant and the receiving equipment necessary to unload
the trucks and place RDF in Union Electric Company's storage bin.
The required cost information was obtained with the help of the City of
St. Louis and was used to determine operating and capital expenses for the ap-
propriate cost centers. All expenses incurred by the project were classified
as labor, materials, or plant overhead and allocated to the Processing Facility
or Receiving Facility.
Six days in September 1974, at the vory start of the project, were not in-
cluded because of inaccuracies in determining costs for less than a 1-month pe-
riod, since all city records are kept on a monthly basis.
For comparison purposes, monthly costs were converted to dollars per megay
gram values. The preliminary report concerning the St. Louis processing plant"
reported costs based on the quantity of refuse fuel (RDF) produced. However,
other processing plants in the future undoubtedly will have RDF recovery rates
different from the 81% found in the present study. All calculations presented
here are based on the quantity of raw refuse received, resulting in values of
dollars per megagram of raw refuse.
Monthly operating costs for the total processing plant on a basis of dol-
lars per megagram of raw refuse received ranged from $4.45/Mg ($4.04/ton) to
$57.99/Mg ($52.61/ton) with an average for the 12-month period of $8.26/Mg
($7.49/ton). This overall cost figure reflects several months of operation
when the plant performed at considerably less than design capacity. Excessive
downtime and maintenance, characteristic of any first generation project, oc-
curred frequently during this period. The wide variability in unit cost is
due largely to fluctuations in the volume of activity. For example, the month
of June with the lowest volume of 327 Mg (1,200 tons) has the highest unit
cost at $57.99/Mg ($52.61/ton) compared to April which has the highest volume
of 4,854 Mg (2,470 tons) and the lowest unit cost at $4.45/Mg ($4.04/ton).
Labor expense comprises over one-half of the total operating costs and is
in most instances fixed. These expenditures are incurred despite a large amount
of idle time and uneven production schedules when employee services are not
fully utilized. Relatively high maintenance labor costs and maintenance parts
and supplies costs can be attributed to the newness of waste recovery technol-
19
-------
ogy. No breakdown of plant overhead into fixed and variable overhead components
has been attempted; however, on a per-unit basis, these costs should be expected
to vary inversely with volume changes.
The market value of ferrous metal recovered was $35,586, an average $28/
Mg ($25/ton). This resulted in the lowering of the cost of operation. The fer-
rous metal sales have been included in the cost tables, producing a net oper-
ating cost.
Total dollar per megagram costs (total costs divided by total megagrams)
for the 12-month test period are as follows:
$/Mg ($/ton) of raw refuse received
Item Total Lowest value
Plant utilization (%) M.8 84.6
Operating costs
Processing facility 6.00 (5.44) 2.95 (2.67)

Total capital costs 9.39 (8.52) 4.25 (3.86)
Total net processing plant costs 17.65 (16.01) 8.70 (7.89)
Figures 5 and 6 show the relationship between dollars per megagram and
monthly weight received.
An analysis of Table 6 reveals capital costs that are fixed per month and
therefore dollar per megagram capital costs are a direct function of monthly
processing rates. In other words, the correlation is 100% as shown in Figure
5. The variable value is operating costs. Figure 6 shows the total dollar per
megagram operating cost proportioned between the processing and receiving fa-
cility. The processing portion of the plant accounts for the major share of
operating costs.
Statistical analysis of the data showed good correlation between costs and
processing rate. Correlation coefficients ranged from 98 to 99%. These results

and the best fit curve equations corresponding to the correlation coefficients
are shown in Figures 5 and 6. The curves are of the form:

Mg
where h and h are constants.
The curves should not be used to predict results beyond the range of
monthly processing rates shown. For example, a significant increase in amount
processed may require more employees which would change the cost-curve equa-
tion.
The important conclusion is that the dollar per megagram rate of total
costs is a function of amount processed. Lowest rates occur at the highest
monthly processing rate. Therefore, a commercial plant operating at high plant-
utilization percentages could be expected to have costs close to the lowest
monthly value occurring at St. Louis when plant utilization was 84»67o.
ELECTRIC POWER CONSUMPTION
Figure 7 shows the daily variations in electric power consumption expressed
as kilowatt-hour per megagram of raw refuse processed. The daily results were
quite variable because of the high variability in the daily amperage of the ma-
jor motors. Comparison of the daily kW-hr/Mg for the haramermill versus Mg/hr
processing rate yielded only a 52% statistical correlation which is too low a
correlation to allow any reliable conclusions to be made. Any trends that might
possibly exist are lost in the daily variation. As shown in Table 7, electric
power used per month did not show the wide variability of the daily usage. Fig-
ure 8 is a graphical presentation of these data, showing that there is no trend
of varying kilowatt-hour per megagram with monthly amount processed. Electric
power consumption per megagram is a relative constant value as demonstrated by
the statistical confidence interval or variability about the mean expressed in
Table 7.
The hammermill is the single largest user of electric power, accounting
for 617o of the total processing facility power consumption.
Electric power consumption at the receiving facility was not recorded.
However the receiving facility has only 146 connected kilowatts compared to
1,748 connected kilowatts at the processing facility. Also, since the receiv-
ing facility operated on the average only 45 min/18-Mg (45 min/20 ton) truck-
load of RDF, it would not have a major effect on total power consumption.

EQUIPMENT DOWNTIME AND MAINTENANCE
Table A-10 of Appendix A lists the plant downtime during processing days.
Downtime represents incidents that caused the plant to cease operations at time
periods when it would otherwise not be required. Therefore, the total weekly
time required to handle a given amount of refuse is the sum of the actual pro-
cessing time and the downtime.
Table A-11 of Appendix A lists the major items of maintenance performed
that were not counted as downtime. Maintenance occurred either during the
plant operating time, before or after the plant was actually processing ref-
use, or on the days when the plant was not processing refuse.
Two major plant breakdowns occurred during the test period. Ten days of
downtime occurred in December 1974 because of a broken chain on the drag chain
conveyor for the ADS system. Spare sections of this chain were not stocked at
the processing plant, and this length of time was necessary to acquire new
chain sections from the manufacturer and replace the old chain. Since St. Louis
is a demonstration plant, this was not a serious problem. However, at a commer-
cial refuse processing plant, an inventory of spare parts such as this ADS drag
chain would be advisable.
The second major breakdown occurred in May 1975. The electrical lead wires
to the hammermill motor came loose, burning out the lighting arresters and oxi-
dizing the first 3 m (10 ft;) of lead wire. Thirteen days of downtime resulted
while new lead wire and lighting arresters were acquired and installed.
Another category which caused stoppage of refuse processing operations but
cannot be counted against the processing plant is maintenance downtime and a
lengthy strike at the Union Electric power plant. During the test period power
plant maintenance accounted for 21 days and the strike 28 days of no operations
at the processing plant.
Maintenance of the hammers in the hammermill was the single most important
maintenance item at the processing plant. The St. Louid experience was that ham-
mer wear due to refuse shredding is mainly an abrasion problem, but occasionally
there is moderate impacting. A second shift welding crew was used to hardface
the hammers on an as-needed basis. Two different types of hammers, both made
of Hatfield manganese, were used. The original hammers were double faced and
weighed approximately 95 kg (210 Ib) each. The second type of hammer was single
faced with a replaceable tip that is bolted onto a shank. This type weighs
roughly 82 kg (180 Ib) each.
Experience showed that the hammers could not be entirely maintained by the
second shift crew. Buildup of the hammers in place in the hammermill was ini-
tially tried but this practice was discontinued for two reasons.
27
-------
1. Significant buildup (i.e., welding material on the hammers) could not
be done on all 30 hammers in one shift.
2. The balance of the hammermill rotor is lost when large amounts of
buildup material are welded on individual hammers. Therefore, the only main-
tenance done on the hammers in the mill was hardfacing with 4.8- or 6.4-mm
(3/16- or 1/4-in.) welding rod. A semiautomatic wire machine was tried, but
the results were less satisfactory.
At 272 Mg/day (300 tons/day), a set of double-faced hammers must be hard-
faced every day. One face will last at least 4,500 Mg (5,000 tons) and then can
be turned around and the opposite face will last approximately the same amount
of refuse processed. After 9,000 Mg (10,000 tons), the hammers were removed and
sent to a welding shop where 9 to 14 kg (20 to 30 Ib) of buildup welding wire
was added to each hammer depending on the vear. Experience showed that this can
be done at least four to five times without any appreciable change in the base
metal of the double-faced hammers* The cose of rebuilding the hammers is roughly
60 to 70% of the cost of a new manganese hammer. A new hammer will last longer
than a rebuilt hammer due to better wearing properties; however, new castings
are sometimes difficult to obtain.
The replaceable tip hammers were also hardfaced every 272 Mg (300 tons).
However, their life is much less than thosr?. of the double-faced hammers. This
difference could be due to the fact that they are 14 kg (30 Ib) lighter per ham-
mer. Buildup of the replaceable tip hammers was done with a semiautomatic weld-
ing wire machine by the plant/maintenance personnel.
In order to use the welding wire on the replaceable tips, it was found nec-
essary to form a mold by placing 25-mm (1-Ln.) carbon plates around the tips to
keep the welding wire from flowing off the sides of the tips. After the tips
have been built up, the carbon plates are removed and the sides filled to seal
any gaps between layers. It was necessary to set up at least two tips and alter-
nately weld between hammer tips to minimize heat buildup. A maximum of two tips
per 8-hr day is the most that one man can be expected to rebuild because of set
up time of the jigs and the cooling time required to avoid overheating of base
metal.
The configuration of the replaceable tips caused various problems. If the
end of the retaining bolt was exposed to impact, they were difficult to remove.
This bolt must be tightened regularly even though it has a lock-washer. The tip
itself wears more rapidly than a comparable two-sided hammer. In addition, ex-
cessive wear can expose the head of the belt that secures the tip, allowing it
to fly off during operation.
Various buildup and hardfacing materials were tried. A summary of these
materials and their properties is shown below. Basically the plant experience
has been that for building up hammers, Stoody Dynamang rod and McKay 218-0 weld-
28
-------
ing wire, 2.8-mm (7/64-in.) diameter, have worked well. They are both well
suited for use on manganese. When set at its higher amperage rating, the McKay
alloy gives good penetration and very little slag. For hardfacing, either Amsco
X-53 or McKay 55 TIC were used. They both have very similar wearing properties.
The Amsco is more difficult to weld but is less expensive. Generally, only one
welding pass was used due to the time involved.
The four products mentioned above are those that were selected from the
various materials tried at the St. Louis plant and should not be interpreted
as being recommended for use over other products which may be available.

CHARACTERIZATION OF PLANT EQUIPMENT
The refuse processing facility is made up of several major pieces of equip-
ment as well as many conveyors, etc. In order to characterize these items, their
physical characteristics are described in Appendix A (Table A-l). Since most of
the items of equipment are electrically driven, the electrical characteristics
of each have also been tabulated in Appendix A (Table A-2). By far, the largest
power users are the 933-kW (1,250-hp) hammermill, the 149-kW (200-hp) ADS fan,
a 112-kW (150-hp) storage bin discharge screw conveyor, and the 75-kW (100-hp)
nuggetizer. The nuggetizer is a rotary mill used to increase the bulk density
of the ferrous metal scrap by-product. As discussed in the preceding section
on electric power consumption, the hammermill accounted Cor 61% of total elec-
tric power consumption.
Corresponding data for the refuse receiving facility at the power plant
are shown in Appendix A (Tables A-4 and A-5). All motors, except the hamraermi11,
and the blower for the pneumatic-conveying line at the receiving facility op-
erated at less than their full load current rating. The hammermill, storage bin
discharge screw conveyor, nuggetizer, and air density separator (ADS) fan motor
currents were measured daily because of their large size and possible varying
load. Figure 9 depicts these daily readings.
Daily amperage recordings were not made at the receiving facility because
this equipment did not operate on a continuous basis. When a truckload of RDF
was discharged into the receiving hopper, a timed control circuit was manually
energized to operate the equipment for 45 min, which was sufficient time to con-
30

vey the RDF to the power plant storage bin. The actual conveying time required
was approximately 30 min, allowing 15 min for cleanout of the conveying equip-
ment before shutdown.
Hammermill current oscillated rapidly because of the varying composition
of the incoming raw refuse. Also, the large m.ass of the mill rotor acts as a
flywheel. Large pieces of metal or other hard-to-niill refuse in the stream tend
to slow the rotor speed, causing a rapid increase in motor current. By the time
the motor current peaks, the hard-to-mill refuse has passed the mill, but the
rotor coasts because of its flywheel effect, which in turn causes a quick de-
crease in motor current. The motor electric pcwer circuit is fitted with a dial
ammeter. It is possible to read the high and low points of the fluctuating meter
dial. However, it was impossible to determine average current draw from this
meter. Therefore, the maximum amperage was recorded and is shown in Figure 9.
The minimum amperage was always 50 amps. Rated motor current is 155 amps, while
the actual current varied between 50 and 300 amps. At no time did the current
stay above 155 amps long enough to trip the motor overload protection circuit.
To determine hammer-mill power consumption, the kilowatt-hours used each day
were recorded since January 22, 1975.
The hammermill bearings are of prime interest since a major plant shutdown
had occurred before the start of the test period due to a bearing failure. Bear-
ing skin temperature is an indication of upcoiring bearing failure. Therefore,
daily skin temperatures were recorded and are reported in Figure 10. The bearing
manufacturer considers 79°C (175°F) as the maximum safe skin temperature. The
highest temperature reached during the test period was 72 C (162 F). The trend
is for the outboard bearing away from the motor to run a few degrees hotter,
perhaps because it is the newest bearing, having been replaced after the previ-
ous bearing failure, and therefore it had not worn in as much as the older bear-
ing. However, because the mill rotor is directly coupled to the motor shaft,
the motor bearings may be supporting a small amount of the inboard bearing load,
causing cooler inboard bearing temperatures.
ADS air flow rates were monitored daily by measuring the pressure drop
across a fixed orifice plate which was calibrated during the plant environmental
tests. Wet and dry bulb temperature readings were taken to determine ambient and
ADS air discharge relative humidity. This information is reported in Figure 11.
Relative humidity was always above ambient in the fan discharge, showing that
the ADS system picks up moisture from the refuse as it passes through the air
stream.
The relative humidity of the hammermill dust collection cyclone exhaust
was also recorded on 12 different days and foi.nd to be 100% at all times.
Therefore, there is also a moisture loss from the refuse as it passes through
the hammermill, adding to the material weight loss. A complete listing of all
daily recordings of kilowatt-hours, amps, temperatures, and air flow is con-
tained in Appendix A (Tables A-12 and A-13).

PLANT MATERIAL FLOW AND CHARACTERIZATION
Material flow through the plant is defined by eight different flow streams.
Each stream was given a number to aid in sample identification. Table 8 presents
a description of the eight material streams and the point at which they were
sampled (also see Figure 1).
A daily record was kept of the quantity of all input/output streams for
the purposes of making plant material balances. Also, as previously mentioned,
samples of each stream were obtained for the purpose of characterizing these
streams,*
CHARACTERISTICS OF ALL FLOW STREAMS
Results of this work are recorded in the form of weekly summaries of tonnage
and stream characteristics in Appendix B (Tables B-la through B-ljW. Weekly sum-
maries of the proximate and ultimate analyses of RDF are presented in Table B-2.
The total material amounts and overall average values for the test period are
presented in the following Tables 9 and 10.
The actual weight of the storage bin discharge (S3), magnetic belt rejects
(S5), magnetic drum rejects (S7), and ferrous metal by-products (S8) was deter-
mined. The amount of RDF produced each day (S2) was calculated from the S3 ship-
ments and the storage and packer bins daily beginning and ending inventories.
Tables B-la through Z-lM list quantities for the mill discharge (SI). How-
ever, this is actually the total of the raw refuse truck weights delivered to
the processing plant. As discussed previously, the samples of raw refuse were
taken after it had passed through the hammermill. Therefore, the SI quantities
are for raw refuse, while the sample analysis results are for milled raw refuse.
For additional discussion of certain process stream samplings, see Appendix
D, "Statistical Process Evaluation of Process Stream Samples."

For comparison purposes in Tables B-la through E-lH, the nugg'etizer feed
(S6) was calculated as the sum of S7 + S8. ADS heavies (S4) was calculated as
the sum of S6 + S5.
Besides quantifying each process stream, Tables B-la through B-lWalso in-
clude weekly averages of the analysis results in order to characterize the
streams. These averages were computed from the daily sample analysis results
tabulated in Appendix B (Tables B-3a through B-3w), except for the following:
1. Chemical analysis of metals was done on a daily basis only for weeks
September 23 and 30, 1974. Thereafter, this analysis was performed only on a
weekly composite sample to reduce analysis cost.
2. All analyses for the weeks of November 25, 1974, through March 17,
1975, were performed on a weekly composite sample.
The ADS heavies (S4) and the various metal streams (S4, S6, S7, and S8)
contained too high a metal content to make chemical analysis practical. There-
fore, these samples were analyzed visually for metal content. The magnetic por-
tion was separated into tin cans and ferrous metal. Tin cans are magnetic but
contain metals other than ferrous.
The screen size distribution is reported in full. However, to make compari-
sons easier, the geometric mean diameter and the geometric standard deviation
were calculated and reported. These two parameters are a standard method adopted
by the American Society of Agriculture Engineers, Standard ASAE S319, for ex-
pressing the fineness of ground materials. This method assumes a straight line
logarithmic distribution of particle size. The geometric mean diameter is the
size at which half the particles are larger than, and half the particles are
smaller than, the mean. The geometric standard deviation is the dispersion about
the mean. A value close to one means a small dispersion, while a large value in-
dicates that particles are widely distributed over a large size range.
An analysis of the geometric mean diameter data shows that the refuse fuel
(S2) has a slightly smaller mean diameter than the mill discharge (SI). The ADS
heavies (S4) contain the larger particles in the material being fed to the ADS
system. Also, as would be expected, the nuggetizer feed (S6) has a larger mean
diameter than the ferrous metal (S8). An analysis of the geometric standard
deviation data shows that the metal streams have a smaller dispersion about the
mean than the milled raw refuse or the refuse fuel.
Daily plant material flows and heating value results were used to calculate
total weekly energy content of all flow streams. This method of calculating en-
ergy content of the various streams was used instead of utilizing the straight
arithmetic averages of heating value in Tables B-la through B-LW to take into
40
-------
account the daily material weight variations. This was done so that the energy
balance would be as accurate as possible. Table B-4a lists the weekly summary
of kilojoules (Btu's) heat energy content for each flow stream, and Table B-4b
presents the energy content in terms of a percent of the energy content in the
hammermill discharge.
Figure 12 shows the weekly amounts of the weight of RDF and Fe metal re-
covered and the energy content of the PDF, all as a percent of the incoming
raw refuse.
Figure 12 reflects the fact that the RDF kj/kg (Btu/lb) heating value is
higher than the raw refuse, and therefore, the RDF averages a higher percent
recovery from the raw refuse on an energy basis than on a weight basis.
As Table B-4b shows, there was an energy loss which was due primarily to
the weight of material loss through the system. The plant material loss is dis-
cussed more fully in the following section on material balance.
The important conclusions here are that over the total test period, the
plant recovered 80.6% of the raw refuse as RDF and 4.57o of the raw refuse as
ferrous metal by-product. Of the total energy in the incoming raw refuse, 83.0%
was recovered as RDF. The magnetic belt rejects plus magnetic drum rejects con-
tained only 4.0%, of the energy. On an energy recovery basis, there is little
value in trying to recycle the reject material to recover energy.
The nuggetizer was operating at near its maximum motor current. While it
was possible to decrease the magnetic belt spacing and increase the amount of
magnetic metal recovered, to do so would exceed the capacity of the nuggetizer.
All recovered magnetic metal from the magnetic belt is discharged directly into
the nuggetizer. Therefore, in order to determine plant ferrous metal recovery
efficiency, the daily plant material flows and percent magnetic metal of each
stream were used to calculate the weekly total of ferrous metal for each flow
stream and thus the recovery efficiency. As was the case with heating value,
this method was used instead of utilizing the straight arithmetic averages of
percent magnetic metal in Tables B-la through E-ld to take into account vari-
ations in daily quantities.
Table B-5 records the total weekly quantities of ferrous metal and Figure
13 shows the recovery efficiency. The total recovery efficiency over the test
period was only 7270. In future plants, there is room for improvement in ferrous
metal recovery efficiency, either through larger sized nuggetizers or different
recovery systems.
The refuse fuel stream samples were also used to determine proximate and
ultimate analyses of RDF. Weekly summaries of these analyses results were com-
puted, as shown in Table B-2, based on data from Table B-3w. Table 10 shows the

average proximate and ultimate analyses characteristics for the test period and
includes similar data for comparison purposes on Orient 6 coal used at the Union
Electric power plant. This comparison shows that the refuse fuel is lower or
higher than the coal as follows: lower--heating value, fixed carbon, carbon,
hydrogen, sulfur, and nitrogen; and higher—moisture, ash, volatile matter, and
oxygen.
The largest difference is sulfur* The refuse fuel contains only slightly
more than one-tenth the sulfur content of Orient 6 coal during the test period
shown in Table 10. The heating value of refuse fuel is 42% of the coal heating
value.
Tables 9 and 10 have presented the average characteristics of the various
plant flow streams over the total test period. It was observed that considerable
variability occurred from day to day in some of the characteristics. Tables 11
through 18 are a tabulation for each flow stream and characteristic, the range
of data (maximum and minimum values) encountered, as well as the mean or average
value.
Also listed is the total number of samples in the mean and the standard
deviation. The coefficient of variation was also calculated and reported in
Tables 11 through 18. Coefficient of variation (C.V.) is a measure of variabil-
ity because it expresses the standard deviation as a percent of the mean. As
the absolute value of one characteristic increases over that of a different
characteristic, the standard deviation may also increase.
A larger standard deviation does not necessarily mean larger variability,
and thus C.V. is a method of accommodating this restriction. The formula for
C.V. is as follows:
C.V. (%) = S (100)
X.
where X = mean; and
S — standard deviation.
x
Finally the confidence interval above the mean at 95% confidence coeffi-
cient was calculated to show what range of values could normally be expected
when taking a single day's sample.
This analysis was performed only on the daily samples, with one exception
discussed below. The weeks of testing from November 25, 1974, through March 17,
1975, were not included because samples taken during those weeks formed weekly
composite samples instead of daily samples. The difference in sampling methods

a/ Nuggetizer not operating for 2 days and therefore no Fe metal stream (97 - 2 = 95).
-------
Between Daily and weekly composite samples could possibly contribute to vari-
ability; therefore, results from the two methods should not be combined in a
variability analysis.
The one exception is the chemical analysis of metals in SI and S2. Even
during weeks of daily sampling, this analysis was conducted on only a weekly
composite basis, except for the first 2 weeks of sampling. Therefore, the
weekly composite sample results of metals by chemical analysis were analyzed
for variability, yielding 35 samples instead of 97 for the other characteristics.
The mean values shown in Tables 11 through 18 differ slightly from the av-
erage characteristic values shown in Tables 9 and 10. Tables 9 and 10 are the
average of all weeks, including the 13 weeks of weekly composite data. However,
an analysis of the weekly composite values revealed that they fell within the
range of maximum and minimum values found for the daily samples.
An analysis of Tables 11 through 18 show that the variability expressed
as C.V. often becomes quite high when the mean values are very low, such as com-
positional items other than metal in S8 (Fe metal by-product).
For all streams, the categories of heating value, moisture, ash, bulk den-
sity, particle size, and proximate and ultimate analyses generally had lower
variability than the categories of composition and metal analysis. This leads
to the conclusion that comparisons between heating values and moisture and ash
could yield reliable results because of the lower variability of these charac-
teristics.
RDF VARIABILITY
Table 12 shows the variability of RDF (S2) heating value on a moisture as
received basis. Data on moisture, ash, and heating value of RDF were statisti-
cally analyzed, showing an expected, but important, relationship of increasing
heating value with decreasing moisture and ash content. Therefore, heating value
of RDF was calculated on both a moisture free and a moisture and ash free basis.
The statistical standard deviation Sx and the coefficient of variation
C.V. (standard deviation as a percent of the mean) were calculated for the daily
sample data to determine if variability of RDF heating value changes when ex-
pressed on a moisture free or moisture and ash free basis.
Table B-6 shows the results of these calculations which are summarized
below:
53
-------
Characteristic X C.V. (%)
Moisture (wt. %) 26.55 27.40
Ash as received (wt. %) 21.71 21.23
Ash moisture free (wt. %) 29.54 18.10
Heating value as received (kj/kg) 10,636 12.88
Heating value moisture free (kJ/kg) 14,494 9.98
Heating value moisture and ash free (kj/kg) 20,570 6.15
Variability as expressed by C.V. is highest for moisture and lowest for
heating value. The heating value C.V. on a moisture free basis is approximately
three-fourths of that for the moisture as received basis. Heating value C.V. on
a moisture and ash free basis is slightly less than one-half of that for the
moisture as received basis.
Therefore, the heating value of the combustible fraction of RDF is higher
and a less variable value than what would be predicted from the moisture as re-
ceived heating value.
Statistical analysis of the data showed 67% correlation between heating
value and moisture and 77% correlation between heating value and ash. The plot
of the data and the best fit curve equations are shown in Figure 14.
EVALUATION OF DATA ON DOUBLE GRIND TESTS
Tests were conducted during the week of February 17, 1975, to define the
characteristics of double grind refuse. The procedure used in the tests was to
collect the ADS light and heavy fractions produced on February 18, and truck
them back to the raw refuse receiving floor for regrinding on February 19. Sam-
ples of the main process streams were collected by the usual procedures during
the regrind tests, and the collected samples were then subjected to the usual
analysis.
Characteristics of the double grind refuse are shown in Table 19. Table
20 shows the proximate and ultimate analyses of double grind refuse derived
fuel (RDF) compared to the average of single grind RDF.
Double grind RDF produced in the test amounted to 76.8% by weight of the
incoming raw refuse. The ferrous metal recovery efficiency was 75.8%. Neither
of these values represents a significant improvement over single grind condi-
tions, as they fall within the range of values for single grind RDF. However,
there may have been some material loss due to spillage because of the procedures
involved in returning the single grind material to the receiving floor. The ma-
terial weight loss error for the double grind material balance was 14.9% which
is higher than the total test period material loss of 7.6%.

-------
Energy content of the double grind RDF was 88,6% of the energy content of
the incoming raw refuse. This value compares favorably with the total test pe-
riod average value of 83,0% for single grind EDF.
The high energy recovery for double grind RDF is a result of the high heat-
ing value of 14,132 kJ/kg (6,075.7 Btu/lb) at 24.9% moisture. This heating value
is higher than would be predicted from the data previously obtained for single
grind RDF. The data for single grind RDF summarized in Figure 14 indicate that
a heating value of 10,851 kJ/kg (5,065 Btu/lb) would be expected for single
grind RDF at a moisture content of 24.9%. The highest heating value for a single
grind RDF near this moisture level was 13,614 kJ/kg (5,853 Btu/lb) at 23.9%
moisture.
The oxygen and volatile matter content of the double grind RDF was higher
than the average for single grind RDF but not outside the maximum and minimum
values for single grind RDF.
The high heating value 14,132 kJ/kg (6,075.7 Btu/lb) for the double grind
RDF appears to be due to the higher percentage of paper in the fuel. Double
grind RDF contained 77.7% paper compared to the highest daily value of 71.8%
paper for single grind RDF. The percent paper in the hammermill discharge (SI)
was relatively high (67.5%), but higher values were previously found on 3 days
for single grind material. Therefore, the high percent paper in the double grind
RDF is not fully attributable to a correspondingly high percent paper in SI.
Mean particle size of double grind RDF was not significantly different
from the average for single grind RDF. Geometric mean diameters are 8.4 mm ver-
sus 8.6 mm (0.33 in. versus 0.34 in.). However, the geometric standard deviation
of 2,56 for double grind RDF was less than the lowest daily value of 2.62 for
single grind RDF. Thus, there is a smaller particle size dispersion about the
mean for double grind RDF.
The particle size geometric mean diameter of 6.1 mm (0.24 in.) of the ham-
mermill discharge for the double grind material was only slightly smaller than
the daily value of 6.4 mm (0.25 in.) for single grind material. The dispersion
about the mean for double grind material fell within the range found for single
grind material.
The particle size and dispersion of the double grind magnetic belt rejects
and ferrous metal by-products was within the range for single grind material.
Processing rate for the double grind material was 30.6 Mg/hr (33.7 tons/hr)
which is within the range found for single grind.
58
-------
In summary, there is a trend of improved RDF quality due to double grinding,
However, this conclusion was made with only 1 day's test data and further test-
ing is needed to verify this trend. Logistics of material handling at the St.
Louis facility make it very difficult to conduct a double grind test, and there-
fore, additional tests were not conducted.
EVALUATION OF DATA ON FINE GRIND TESTS
A series of tests to determine the characteristics of fine grind PDF was
conducted during the period of April 18 to 23, 1975. In order to conduct these
tests, the normal grates with 76-mm (3-in.) square openings were replaced with
grates having 32-mm (1-1/4 in.) diameter openings. Samples of the main process
streams were collected by the usual procedures, and the collected samples were
then subjected to the usual analysis.
Table 21 shows the average characteristics of the fine grind refuse for
the 5-day test period. Table 22 presents a comparison of the proximate and ulti-
mate analyses of fine and the regular grind RDF, while Table 23 shows sample
variability of milled refuse.
Fine grind RDF represented 73.8% by weight of the incoming raw refuse. On
the basis of weighted average values, fine grind RDF energy recovery was 74.5%
and ferrous metal recovery was 64.3%.
Ferrous metal recovery is within the range of values found for regular
grind material. However, the weight recovery of RDF at 73.8% is slightly lower
than the lowest value of 74.07» for regular grind material.
One contribution to the decreased material recovery is the increase in air
emissions from the ADS cyclone which are discussed in detail in a later section
of this report. A marked increase in kilograms per hour (pounds per hour) emis-
sions from the ADS systems occurred for fine grind material as compared to emis-
sions from normal grind material. Emissions from the ADS increased from an aver-
age of 22 kg/hr (50 Ib/hr) for normal grind to 57 kg/hr (125 Ib/hr) for fine
grind. This increase is significant considering that the normal grind processing
rate of 36 Mg/hr (40 tons/hr) was reduced to 23 Mg/hr (25 tons/hr) during fine
grind, which means that the emission factor increased from 0.95 kg/Mg (1.90 lb/
ton) for normal grind to 2.73 kg/Mg (5.46 Ib/ton) for fine grind. It should be
noted, however, that the reduced processing rate for fine grind also necessi-
tated reduced air flow in the ADS system, which may have impaired removal ef-
ficiency in the ADS cyclone.
Hammermill dust collection system particulate emissions in terms of kilo-
grams per megagram (Ib/ton) are quite small compared to the ADS emissions, and
therefore, would not contribute significantly to decreased material recovery.

-------
In addition to accounting for a portion of the decreased material recovery,
the increases in air emissions from the ADS and HM systems indicate a more dif-
ficult materials handling problem with fine grind EDF (e.g., windborne losses
are likely to increase, etc.).
Heating value of the fine grind RDF was low, being only 9,630 kJ/kg (4,140
Btu/lb) at 25,087a moisture. As shown in Figure 14, a heating value of 10,828
kJ/kg (5,055 Btu/lb) would be expected for regular grind RDF at this moisture
content. This low RDF heating value was due to the low heating value of the in-
coming raw refuse. Heating value of SI (mill discharge) for fine grind tests
was 9,476 kJ/kg (4,074 Btu/lb) at 24.6% moisture compared to the lowest weekly
average for regular grind of 10,697 kJ/kg (4,599 Btu/lb) at 28% moisture. The
reason for the lower heating value of SI is not apparent from the compositional
analysis.
The majority of regular-grind refuse streams will pass a 38.1-mm (1.5-in.)
square screen while the majority of fine grind refuse streams will pass a 19.1-
mm (0.75-in.) square screen (see Table 21). For the first four daily samples,
100% of the sample from SI passed a 38.1-mm (1.5-in.) screen. On the fifth day,
the hammermill screen was torn badly enough that only 99.1% of the SI sample
passed a 38.1-mm (1.5-in.) screen. Therefore, for the 5-day average, 99.8% of
the fine grind material passed a 38.1-mm (1.5-in.) screen.
The following comparison shows that the reduction in mean particle size
was approximately equivalent for all streams except the ferrous metal (S8),
which had a larger size reduction.

in size)
The nuggetizer produced a much smaller size of ferrous metal by-product
during fine grind because it has a smaller input particle size material to han-
dle.
The dispersion about the mean (geometric standard deviation) was smaller
for fine grind except for the ferrous metal by-product which exhibited no change.
63
-------
Using the fine grind grates reduced the hammermill capacity to an average
of 22.6 Mg/hr (25 tons/hr), with a range of 20.8 to 27.0 Mg/hr (23 to 30 tons/
hr). Regular grind processing rate during the period September 23, 1974, through
September 5, 1975, averaged 31.0 Mg/hr (34.2 tons/hr).
After each day's operation, the hammermill was opened and the fine grind
grate inspected. By the end of the second day, structural failure of the grate
had commenced. The grate was torn in several places and these tears became larger
and more numerous with each successive day's operation. Several irregular splits
approximately 152 mm (6 in.) long had occurred in the grate. Continued operation
would have caused these to open up, allowing large refuse particles to pass into
the system which may have clogged the materials handling equipment.
In summary, the processing plant is capable of processing refuse using 32-
mm (1-1/4 in.) diameter opening hammermill grates with a 28% reduction in average
processing rate as compared to the normally used grates with 76-mm (3-in.) square
openings. However, because grate life was only 869 Mg (958 tons), fine grinding
of raw refuse does not appear attractive. Also, associated testing of fine grind
refuse at the power plant did not indicate any significant increase in combustion
efficiency.
PLANT MATERIAL BALANCE
The total material balance for the entire 1-year test period of September
23, 1974, through September 30, 1975, is shown in Appendix B (Tables B-7a and
B-7b). Table B-7a shows the actual weights of the material balance while Table
B-7b shows the material balance in percent form.
During this 1-year period of 53 weeks, plant production occurred during
45 weeks with 8 weeks during which the plant did not operate. Following is a
summary of the yearly total.

Material balance weight
loss 2,124.1 7.57
The data in Tables B-7a and B-7b and the summary show that there was always
a material loss. That is, the amount of plant output (32, 35, 37, and 38) never
equaled the amount of incoming raw refuse (SI). There are five possible sources
of this loss,
1. Particulate and moisture loss from the hammermill dust collection sys-
tem.
2. Particulate and moisture loss from the ADS system air flow.
3. Spillage from equipment.
4. Possible scale errors in weighing magnetic drum rejects (S7).
5. Possible scale errors in weighing trucks.
Emission test data have shown that the maximum particulates and moisture
losses from the hammermill and ADS system could account for about 1.5% of the
losses. Unfortunately, no method was available to accurately measure equipment
spillage. However, this spillage is estimated to be considerably less than 1%
basis visual observations, and therefore, would not account for much of the
overall material loss.
Magnetic drum rejects were weighed each day by MRI field personnel. The
rejects were, collected in a small enclosure underneath the magnetic drum. At
the end of each day, this material was manually scooped into a 0.02 m (0.7
ft^) container and weighed using a portable spring scale. The accuracy of this
65
-------
scale was verified by weight comparisons to the large dial scale located in the
field trailer and used to make bulk density measurements. Also, magnetic drum
rejects account for only 0,1170 of the total plant input, so that even if scale
errors existed, they would not have a major effect on the total plant material
balance.
Because the above four items of particulate loss, moisture loss, spillage,
and magnetic drum reject scale error could not account for all of the plant ma-
terial loss, scale operations in weighing trucks were investigated as a possible
cause of the material imbalances.
The scale at the refuse processing plant is not used for buying or selling,
and therefore is not a certified scale. That is, it is not a scale whose accuracy
is periodically checked and certified as being correct by the City of St. Louis,
Division of Weights and Measures, the governmental agency responsible for licens-
ing weighing devices used in commercial transactions in the St. Louis area.
Therefore, a test was conducted whereby refuse processing plant trucks,
selected at random, were weighed both on the refuse processing plant scale and
official scales, inspected and licensed by the St. Louis Division of Weights
and Measures. The number of trucks involved in this study and the scale error
is as follows:

The Industrial Sugar Company scale is located at 3600 South First Street,
only 5 blocks away from the refuse processing plant at 4100 South First Street.
The Union Electric scale used was the truck scale at the Union Electric Meramec
plant.
The result of this test is that the plant weight records show more raw ref-
use received and less Fe metal and magnetic belt rejects shipped than is actually
true. These two scale errors account for a material loss in the plant weight rec-
ords. However, this is offset by the fact that the plant weight records show more
66
-------
RDF shipped than was actually true, making up in part for the material loss due
to scale error in weighing the raw refuse and Fe metal and rejects trucks.
Also, these scale errors cannot be summed directly because they do not all
apply to the same tonnages. Table B-7b shows the total recorded tonnage for the
year. Applying these known scale errors and the 1.57» moisture and particulate
loss results in a net 6% material loss as shown in Figure 15.
This test shows that the individual categories of truck errors partially
cancel one another and do not yield any scale error significant to the total
material balance weight loss.
The RDF produced was calculated by taking the storage bin shipments for
the week and applying the storage bin differential between the start and end
of the week. The amount of RDF in the storage bin was estimated from visual ob-
servations. Thus, it is possible that a material balance error could result from
errors in calculating the storage bin differential. An analysis of the storage
bin shipments was made by totaling the storage bin shipments over the year's
test period taking into account that the storage bin was empty at the end of
the test period and contained an estimated 11.8 Mg (13 tons) at the beginning
of the test period. The total storage bin discharge agreed within 1% of the cal-
culated total RDF produced. Therefore, while storage bin inventory differential
could possibly produce a material balance error during an individual week, the
storage bin inventory differentials cancel out over the total test period and
the 6% unaccounted material loss cannot be explained from the method used to
calculate RDF produced.
The RDF trucks were all weighed. When RDF trucks are loaded at the packer
station, a log sheet is prepared showing the trucks loaded per day. Also, at
the power plant receiving building, a similar log sheet is prepared, showing
the trucks unloaded per day. These two log sheets and the scale records all
agreed. Therefore, to have an RDF truck not weighed, all three records (load,
scale and unload log) would have to be in error, and this is highly unlikely.
Three possibilities exist which could explain part of the remaining ma-
terial balance error.
1. Unweighed raw refuse trucks; When incoming raw refuse trucks enter
the plant, they first pass over the city scale. After weighing, the truck driver
is then told to proceed either to the incinerator or the refuse processing plant
and his truck weight recorded accordingly by the scale operator on a log sheet.
While it was never observed to have happened, it is possible that the raw refuse
truck driver could have made a mistake and discharged his truckload at the in-
cinerator when he was intended to discharge at the processing plant.

2. Unweighed Fe metal and rejects trucks: When the magnetic belt reject
and Fe metal trucks are full, they are weighed on the city scale before they
discharge their loads on the city property. While it was never observed to have
happened, it is possible that a plant workman could have mistakenly discharged
a truckload of material either at the Fe metal stockpile or the city landfill
without weighing his truck.
3. Hammermi11; The weight of the raw refuse received is the weight of
material before it enters the hammermill. Samples were taken after the mate-
rial left the hammermill (SI). Therefore, comparison of samples before and af-
ter the hammermill was not possible. There could have been moisture and other
volatile material loss during the shredding operation in the hammermill. It is
known that there was moisture loss through the hammermill dust collection sys-
tem and this has been accounted for. However, there could have been additional
loss through the inlet throat and discharge opening of the hammermill. It was
observed that outward flowing air currents or blowback from the hammermill in-
let throat did occur. There was no way to measure this air flow, but it con-
ceivably could carry away moisture and other vapors from the refuse as it is
being shredded.
Between 1966 and 1972, studies of shredding municipal refuse were conducted
at Madison, Wisconsin.— The process involved in this study was shredding only;
no air separation, metal recovery, or other process operations were involved.
Recent conversations with personnel in the Engineering Division, City of Madison,
revealed that they had experienced material loss ranging from 2 to 5%. Since only
a shredder was involved, this loss is entirely the loss attributable to the shred-
der. Like the St. Louis project, they could not account for this loss through doc-
umentation. They theorize that the loss is due to moisture loss, spillage, and
trucks sometimes not being weighed.
3/
In 1970, Sanders— reported results of the Bureau of Solid Waste's experi-
ments shredding municipal refuse. In one set of experiments, measured moisture
loss across the shredder ranged from an average 4 to 77<>. In a second experiment,
actual measured weight loss across the shredder was 5.987..
While the St. Louis project unaccounted error of 6.047=, is slightly higher
than the Madison project error range of 2 to 57<>, it is within the 4 to 7% mois-
ture loss range and practically identical to the 5.98?0 weight loss reported in
the Bureau of Solid Waste study. While it has not been possible to document the
precise reason for the St. Louis weight loss, it is important to note that others
have had the same experience.
69
-------
The St. Louis plant was not constructed to allow material weight checks di-
rectly across the hanmermill or any of the other pieces of processing equipment.
In any future projects, the initial plant design should consider need for or use
of weighing equipment. Such items as optional by-pass chutes and/or conveyors
and space allowed for installation of automatic in-plant bulk weighing scales
should be considered. Availability of such equipment would permit detailed weight
checks across individual items of equipment.

EVALUATION OF ENVIRONMENTAL IMPACTS
Studies conducted at the processing plant to evaluate environmental impacts
were directed to quantifying emissions and evaluating other environmental aspects
of the facility and its operations. The objectives of the tests follow:
1. Determine mass emission rates and particle size for particulate matter
discharged from the Air Density Separator (ADS) and from the hammermill (HM) cy-
clone for both regular grind and fine grind refuse.
2. Conduct analysis of particulate matter emissions in an effort to iden-
tify potential hazards that may exist due to bacteria and virus.
3. Quantify water effluents and pollutant levels therein.
4. Make preliminary assessment of the leachability of all solid waste ef-
fluents that do or can occur from this facility.
5. Carry out a noise survey in and around the processing plant for compari-

Results of the environmental test activities are presented and discussed
in the following subsections of this report. In some cases, details of test pro-
cedures and tabulations of data are contained in the appendices as noted.
AIR EMISSIONS: PANICULATE AIR EMISSIONS FROM AIR DENSITY SEPARATOR AND HAMMER-
MILL CYCLONES
Tests were performed to determine conventional particulate emissions as
well as bacteria and virus levels in the exhaust streams from the ADS and HM
systems. Results of the tests are discussed next.
Conventional Particulate Emissions
Primary sources of air emissions are the discharges from the Air Density
Separator (ADS) cyclone and the hammermill dust collection system (HM) cyclone.
Both of these sources were tested on three separate periods, twice during periods
when regular grind RDF was being produced, and one other period during which fine
71
-------
grind RDF was being produced for Union Electric via substitution of 32-nm (1-1/4
in.) diameter round hole grates in the hammermill rather than the normal 76 by 76-
mm (3 by 3-in.) opening grates.
Analysis of the processing plant refuse streams during the test periods is
included in the data tabulated in preceding sections of this report. A descrip-
tion of the air emission test procedures and tabulations of the test data are
presented in Appendix C.
A summary of the mass emissions from the ADS and HM for all three test pe-
riods is shown in Table 24. The particle size distribution tests that were car-
ried out during two of those periods are presented in Figures 16 and 17.
ADS Emissions—
Mass emissions from the ADS cyclone for the eight regular grind tests ranged
from 9.0 to 33.5 kg/hr (19.9 to 79.9 Ib/hr) with an average of 27.2 kg/hr (60 lb/
hr) with corresponding emission rates from 0.28 to 1.99 kg/Mg (0.56 to 3.97 lb/
ton) with an average of 0.95 kg/Mg (1.89 Ib/ton). This emission rate indicates
the need for controlling or reducing the emissions in future plants of this type.
Particle size tests on the ADS cyclone discharge during regular grind opera-
tions (Figure 16) showed that at least 80% of the particulate emissions were
larger than 10 p,m. Based on visual observations, it was suspected that a consid-
erable number of the emissions were probably much larger than 10 pin.
It was thought worthwhile to try to quantify the emission of these particles
for comparison with the overall average emission rate of 27.2 kg/hr. Therefore,
a net arrangement was constructed of nylon mesh with" openings of 6.4 by 6.4 mm
(1/4 by 1/4 in.). During 4 days in December 1974 and January 1975, this net was
placed over the outlet of the ADS fan for approximately 1/2 hr each day in an
attempt to capture and weigh all of the larger particles. These tests (Table 25)
showed that the emission rate of large particles greater than 6.4 mm (1/4 in.)
ranged from 2.0 to 3.6 kg/hr (4.3 to 8.0 Ib/hr) with an average of 2.5 kg/hr
(5.6 Ib/hr). The composition of this effluent was also scrutinized. Much of it
was found to be pieces of paper and plastic, as well as miscellaneous fibrous
materials. Most importantly, the heating value of these emissions was 17,617
kj/kg (7,574 Btu/lb) higher than the RDF produced on the same day.
Because the emission of the larger particles was a nuisance problem in the
near plant vicinity, the ADS discharge ducting was changed to direct the discharge
into a settling chamber area underneath the RDF storage bin. This settling chamber
was an area approximately 11.6 by 5.2 m (38 by 17 ft) and 3.0 m (10 ft) in height
which was enclosed with 1.6 mm (1/16 in.) square opening nylon mesh. No tests
were conducted to determine efficiency of particulate removal of this arrangement,
but it did remove most of the larger particles and abated the associated nuisance
problem. However, more effective control methods such as use of fabric filters is
recommended in future plants.

-------
As mentioned earlier, another series of mass emission (and particle size)
tests was conducted on the ADS system when fine grind EDF was being produced.
Data from these tests (Table 24) showed that emissions averaged 57.0 kg/hr
(125.6 Ib/hr), which is about twice as high as the average for the regular
grind tests. Perhaps more importantly, the average emission rate was 2.74 kg/
Mg (5.47 Ib/ton), about three times higher than that for regular grind refuse.
The reduced processing rate for fine grind necessitated reduced air flow in
the ADS system, which may have impaired removal efficiency in the ADS cyclone.
The particle size distribution of the ADS emissions during the fine grind tests
was similar to those during regular grind tests (Figure 16) and certainly did
not indicate any increase in the percent of particles smaller than 10 pm. On
this basis, it can be concluded that decreasing the grind size does not increase
the percentage of fine particles greater than 10 pm in the ADS emissions.
HM Emissions--
During the same three periods when the ADS emissions were measured, similar
tests were also carried out on the discharge from the hammermill (HM) cyclone.
As expected, the emissions from the HM are less than from the ADS system, but
the data for regular grind RDF cover a wide range of 0.008 to 3.9 kg/hr (0.02
to 8.6 Ib/hr). Emissions measured in the first two tests (November 1974) are
much lower than those measured in the three tests later in July 1975. Reasons
for this variation are not known, but confidence in the July 1975 tests is bet-
ter because the HM cyclone had been cleaned out and inspected on the day preced-
ing the July 1975 tests.
If it is assumed that the July 1975 regular grind tests are most represen-
tative, then comparisons with the fine grind tests in April 1975 lead to the con-
clusions that HM fine grind emissions on an hourly basis are somewhat lower, av-
eraging 2.8 kg/hr (6.3 Ib/hr) versus 3.4 kg/hr (7.5 Ib/hr), but that the emission
factors are about the same, approximately 0.13 kg/Mg (0.26 Ib/ton). In any case,
it is evident from the data that the emission rate from the HM is considerably
less than that from the ADS system.
The emission test data from the HM cyclone (Appendix C) show that the efflu-
ent gas temperature was about 14 C (25 F) above ambient and that it contained a
relatively high moisture content (~ 47» moisture by volume) being near saturation.
This result verifies the expectation that the HM causes a temperature increase
and removes some moisture from the refuse stream.
Particle size distribution tests were also conducted on the effluent from
the HM cyclone as shown in Figure 17. As was the case for the ADS cyclone efflu-
ent, the tests showed that most of the particulate matter (> 807=) was greater
than 10 fim in size.
77
-------
Comparison of the particle size distribution for regular grind and fine
grind RDF (Figure 17) seems to indicate that a greater portion of the emissions
were smaller than 10 pja for regular grind RDF than for fine grind RDF. However,
this is probably a result of the fact that the regular grind particle size tests
were done at the same time as the November 1974 mass emission tests, which were
much lower than in succeeding tests. No particle size tests were carried out
during the later tests in June 1975.
Potentially Hazardous Air Emissions (Bacteria and Virus Emissions)
Processing of municipal solid wastes, as is done in preparing the RDF at
the St. Louis operation, does involve materials that undoubtedly contain some
pathogens. Part of the environmental evaluations included some preliminary tests
to quantify bacteria and virus levels in the air streams emitted from the ADS
cyclone, HM cyclone, and the RDF storage bin. Levels in suburban ambient air
were also determined to provide some basis for comparison. Samples were taken
at the following locations:
* Air exhaust duct leading from the ADS and HM cyclones.
'* Inside walkway at top of storage bin where RDF is discharged from a
conveyor belt.
* Backyard of a single family suburban residence located 32 km (20 miles)
west of the refuse processing plant.
The methods of collecting samples for the ADS and HM emissions for bac-
terial and virus analysis were the same as those described in Appendix A for
the particulate mass emission tests. The method is basically a high volume air
sampling technique in which the particulate matter is collected on filter pa-
per. Since the amount of particulate matter collected on the filter is quite
high within the 1 to 10 g (15.4 to 154 grain) range, it was possible to remove
most of the particulate catch from the filter, and split it into two parts,
which were weighed and transferred into sterile bottles. A diagram depicting
handling, disposition, and analysis requirements for the samples is shown in
Figure 18.
Air samples from the top of the RDF storage bin and ambient air samples
were also handled as shown in Figure 18 with the samples being obtained by use
of ordinary ambient high volume particulate samplers. However, in the case of
the suburban ambient air samples, the amount of collected particulate was so
small that it could not be removed from the filter and analyzed separately, as
was the case for the other samples (ADS, HM, and storage bin). The storage bin
samples were not analyzed for virus content, and it was not possible to deter-
mine the particulate emission rate from the top of the storage bin (but it is
probably much lower than that from the ADS cyclone).

Results of the bacteria and virus tests are presented in Tables 26 through
28. Interpretation and evaluations of these results are provided in the follow-
ing two sections: the first pertaining to the bacteria results, and the second
pertaining to the methodology and results for the virus tests.
Bacteria Emissions--
Results of the bacteria tests indicate bacteria levels that are several
orders of magnitude higher than in the suburban ambient air samples (Table 28).
Also, several of the samples showed the presence of salmonella, which are the
agents responsible for some forms of food poisoning.
It was expected that fecal coliforra and other bacteria would be present
in the emissions from the plant because of the nature of the material processed.
However, the seemingly large numbers make it imperative that they be evaluated
on some rational basis. Because of the possible significance of the results, a
search of the literature was made in an effort to obtain additional information,
especially that pertaining to bacteria (and virus) levels in air. This litera-
ture search did provide some useful input for evaluating and comparing the
St. Louis results as discussed below.
4/
Work by Peterson- indicated that samples of raw refuse contained total
bacteria ranging from 7.6 x 10' to 4.1 x 10° counts per gram (3.5 x 10 to
1.9 x lO^-1 counts per pound) and fecal coliform of 2.3 x 10 to 4.0 x 10 counts
per gram (1.0 x 10^ to 1.8 x 10° counts per pound). These values are quite close
to those found in the particulate matter discharged from the ADS and HM cyclones,
In summary, as expected, particulate matter discharged from the ADS and HM cy-
clones contains about the same level of bacterial contamination as does the raw
refuse.
Bacterial levels in air have been studied to a limited extent for some op-
erations where airborne pathogens might present a potential hazard (i.e., ref-
use handling operations and sewage treatment plants).
Glysson— conducted tests on bacteria in air samples taken inside and out-
side of an enclosed refuse handling facility.* In general, it was found that
the air inside the facility contained bacteria levels of 530 to 78,000 counts
per cubic meter (15 to 2,210 counts per cubic foot). Bacteria concentration in
the air samples taken 30 m (100 ft) outside of the enclosed facility ranged
from 134 to 629 counts per cubic meter (3.8 to 17.8 counts per cubic foot)
which compares well with the ambient samples taken in St. Louis. Preliminary
reports of work by Trezek".' at the Richmond Field Station Resource Recovery
System showed initial bacteria levels of 600 to 1,770 counts per cubic meter
(17 to 50 counts per cubic foot) within the facility which increased to 4,730
to 12,700 counts per cubic meter (134 to 360 counts per cubic foot) during
operating periods.

cation.

Other work by Peterson" at several incinerator plants was directed to determina-
tion of bacterial counts in refuse handling areas such as dumping floor, charging
floor, and residue area, showed bacterial levels of 141 to 14,130 counts per cu-
bic meter (4 to 400 counts per cubic foot).

Pereira~ reported on bacterial sampling work done in and around the aera-
tion building of a NYC sewage treatment plant, providing the following results.

In Pereira's work, several specific pathogens were identified in the air samples,
It was concluded that a possible health hazard existed for the sewage plant work-
ers and others who reside in areas where the atmosphere is contaminated by the
gaseous effluent from the sewage treatment plant.
9/
Sorbet— conducted tests of bacterial aerosol associated with wastewater
spray irrigation, and found levels that were significantly above background at
distances 200 m (656 ft) from the sprayer (the greatest distance tested). This
work did show that a disproportionate share of bacteriological decay occurred
within the first 6 sec of exposure, and that atmospheric conditions did exert
an important influence on the aerosol levels.
Thus, bacterial concentrations associated with normal refuse handling op-
erations may range from 530 to 14,130 counts per cubic meter (15 to 400 counts
per cubic foot) up to a maximum of about 70,630 counts per cubic meter (2,000
counts per cubic foot). If these aerosols were not contained, they might affect
ambient levels at a distance of at least 200 to 300 m (656 to 984 ft).
Exposure of refuse workers to the increased bacterial levels could cause
increases in respiratory diseases and dermatitis, but except for one report,
no statistical data were available. The exception was a study by Cimino— on
workers in the NYC department of sanitation, primarily the refuse collection
personnel. This study found no evidence of increased amounts of respiratory
disease in uniformed sanitation men as compared with other departmental titles.
However, it did find that stationary firemen employed at the incinerators had
more episodes of respiratory disease and tended to have longer periods of dis-
ability there. Cimino noted that this difference might have been due to the
older average age of the firemen, but that the smoke and contaminants to which
they were exposed may also have been a factor.
84
-------
Even though the data previously cited indicate increased bacterial levels
associated with refuse handling operations, there are no known standards of
bacterial concentration limits for workers or the general populace. Such stan-
dards, if they existed, would more correctly be directed to specific bacteria
rather than total bacteria levels. However, the work by Glysson^' discussed
the fact that tentative standards for hospital air prescribed 3.5 colonies per
cubic meter (0.1 colonies per cubic foot) in very critical areas, up to an al-
lowable concentration of 1,766 colonies per cubic meter (50 colonies per cubic
foot) in working spaces. Such a standard hardly seems appropriate for refuse
handling operation, or the general public, on the basis of values mentioned by
Peterson— which shows that bacterial levels in country air may be 1,978 counts
per cubic meter (56 counts per cubic foot) and 2,543 to 3,990 counts per cubic
meter (72 to 113 counts per cubic foot) in offices, schools, and factories.
On the basis of current information, it would seem prudent to limit the
exposure of processing plant personnel to bacteria levels which do not exceed
levels found in offices, schools, and factories. That is, bacterial counts prob-
ably should be less than 35,000 counts per cubic meter (1,000 counts per cubic
foot) for in-plant air and 3,500 counts per cubic meter (100 counts per cubic
foot) in ambient air. If these limits are assumed, it does appear that the bac-
terial levels measured at St. Louis may present a problem. Bacterial concentra-
tion in the ADS exhaust which is the largest emission source and is exhausted
near ground level contained bacterial concentrations as high as 318 by 10
counts per cubic meter (9 by 10^ counts per cubic foot). Even if one assumes
that 90% of the particles would settle rapidly (based on previously discussed
particle size data), the levels could still be about 32 by 10 counts per cu-
bic meter (9 by 10^ counts per cubic foot). If it were further assumed that
the emissions are diluted by a factor of 1,000 before reaching the plant bound-
aries, the bacterial level could still be as high as 32,000 counts per cubic
meter (900 counts per cubic foot).
Levels such as those discussed above may constitute a potential hazard,
but the calculated values do not take into account possible rapid die-off ex-
pected for many bacteria. It is evident that there is a need for further test-
ing at the St. Louis facility to measure bacterial levels for the air in and
around the plant boundaries before it can be said that any hazard does exist.
At this point it can only be concluded that a potential hazard may exist. More
definitively, the results to date certainly do not support a conclusion that
there is no potential bacterial hazard.
As a last point, it should be remembered that the mass emission data for
the ADS system indicated the need for control. If efficient particulate control
devices were employed on plants of this type, it is probable that they would
also provide about the same efficiency of removal for bacteria. Similarly it
is recommended that future plants of this type pay particular attention to con-
trol of particulate emissions and design the plant so as to minimize worker ex-
posure.
85
-------
Virus Emissions-
Many of the samples that were tested for total bacterial counts, fecal co-
liform levels, and for salmonella were also tested for their viral contents.
These tests were performed in the Virus Laboratories of MRI. When the tests
were initiated only tests for enteroviruses were planned. However, we later
elected to test also for the bacterial viruses that are found in association
with Escherichia coli« For the virus tests, samples were obtained from the fol-
lowing sources*
1. Particulate matter from air density separator cyclone;
2. Hammermill cyclone; and
3. Suburban ambient air.
Since low levels of viruses had been anticipated and the viruses had to
be eluted from the particulate matter, preliminary processing was needed. Each
air particulate sample was suspended in distilled water by a 30-sec homogeniza-
tion in a Waring Blender or an Omni-mixer. The homogenate was precipitated at
pH 7.0 with 0.5 M GaCl2 and 0.5 M Na2HPO^. (Calcium hydroxyappatite is the prin-
cipal product formed.) This precipitate was recovered by Buchner filtration us-
ing Whatman No. 1 paper. The precipitated material was then dissolved by chela-
tion using 0.3 M disodium EDTA (pH 7.0). The EDTA solution (containing the vi-
ruses) was then dialyzed against distilled water to remove the EDTA. A second
calcium phosphate precipitation step was performed to further concentrate and
purify the sample. Following the second dialysis, part of each sample was used
for viral assay, and the remainder frozen for any necessary reassays. The final
samples from the concentration and purification steps were 20.0 ml each. The
weight of the original particulate matter and the volume of air from which the
sample was obtained were known; therefore, viral assays could be reported per
gram of sample or cubic meter of air sampled.
Enteroviruses were assayed by means of standard plaque technique using the
LLC-MK2 cell line from monkey kidney and the KB cell line derived from an epi-
dermoid carcinoma. Medium 199 supplemented with sterile newborn calf serum was
the nutrient for the LLC-M^ cells. It was also used in the agar overlay medium
for the plaque counts. The KB cells were grown in Basal Eagle's Medium supple-
mented with nonessential amino acids and newborn calf serum. Antibiotics (peni-
cillin, streptomycin, and on occasions fungizone) were added to the media to
suppress any bacterial contamination. Plaques were counted from 4 to 10 days
after the cultures were overlayed. Neutral red (1 to 6,000) was added on the
day the plaques were read and the cells were stained for approximately 4 hr at
37°C (99°F) before counting. When discrete plaques were observed, these were
counted and each plaque considered as one virus. Plaque estimates (PFU = plaque
forming unit) were made for some cultures which showed lysis but without dis-
crete plaque formation. A known standard poliovirus (Type 1) was always assayed
at the same time as each unknown sample so that the tissue culture sensitivity
of the cultures was known for each day's testing.
86
-------
Test for J2. coll bacteriophages were made with the purified and concen-
trated sampled using standard phage techniques.il' The host cells were fecal
coliform strains isolated from sewage samples previously studied on another
MRI program. Serial dilutions of the test samples were added to 4 ml volumes
of melted and cooled to 42°C (108°F) agar to which an appropriate number of
rapidly growing E. coli cells was added and the mixture immediately poured
on the top of a prepoured layer of nutrient agar. These "sandwich" type cul-
tures were incubated overnight after which each discrete plaque was counted
and recorded. Bacteriophage titers in the samples are reported as PFU per gram
or per cubic foot.
Table 26 includes the results for enteroviruses and _E. coli bacterio-
phages for the particulates in the ADS and HM cyclone tests. Table 28 summa-
rizes the viral and microbial data for ambient air samples taken 32 km from
the processing plant.
The data obtained on the viral content of these samples are not as "clean-
cut" as we would like, and the titers for the ADS and HM samples are all much
higher than we had expected.
As expected, we observed no viruses in any of the ambient air samples (see
Table 28). In fact, the ambient air samples were as free of viruses as the blank
filter papers assayed by the same techniques. The absence of viruses in the am-
bient air samples was to be expected since the total bacteria in the particulates
ranged from 25 to 473/m3 (0.7 to 1.4 ft3).
Based upon the high levels of fecal coliforms in the tests of the ADS and
HM cyclone samples, it is not surprising that our enterovirus data are hard to
interpret. Our general impression is that the samples contained appreciable lev-
els of enteroviruses and probably many other agents capable of destroying tissue
culture cells.
The plaques observed in many cases were typical of enteroviruses including
poliomyelitis, but we made no attempts to classify the agents. The data in Table
26 for enteroviruses (based upon tissue culture destruction) clearly prove that
the air samples collected from above the ADS and HM operations contained animal
viruses at least partly of fecal origin. The levels of these agents are quite
high, especially in comparison with data reported by Petersoni=' which showed
enteric virus density in municipal solid waste of 0.32 PFU/g (1.45 PFU/lb).
Peterson's—report also mentions that sewage may contain enteric virus densi-
ties of 0.2 to 4.0 PFU/ml (5.3 x 10"5 to 1.1 x 10~3 PFU/gal.).
The E. coli bacteriophage levels in the ADS and HM samples were nearly
equal to, or higher than, the number of _E. coli determined by fecal coliform
test procedures* These E. coli bacteriophage data confirm the high degree of
fecal contamination reported. The higher bacteriophage counts compared to the
87
-------
coliform counts can be explained by several means, and we cannot be certain which
is the correct reason. Bacteriophage of _E. coli are generally more difficult to
kill than _E. coli; therefore, the higher phage counts can be due to longer or
greater survival of the bacterial virus than the bacteria. Each _E. coli can give
rise to multiple phage if the lytic cycle is completed. Therefore, the higher
phage titers in Table 26 may be a reflection of some phage virus reproduction
on the bacteria found in the waste materials. The action of the phage on the
JE. coli may also reduce the _E. coli counts. The high levels of bacteriophage
for E* coli are also not surprising in the light of positive salmonella tests*
JE. coli and _E. coli bacteriophages are generally present in feces in much higher
levels than salmonella.
Again, as was previously discussed with regard to bacteria, it is difficult
to judge the significance of the virus levels reported in Table 26 because there
are no standards for virus levels in air, and in fact, very little work has been
done in measuring virus levels in air. The previously cited work by Petersonir'
was directed to problems associated with virus levels in disposable diapers
which, contained in municipal solid waste, showed that disposable diapers may
constitute 0.6 to 2.5% by weight of the municipal solid waste. Peterson identi-
fied poliovirus 3 and echovirus 2 in the waste matter contained in some of the
diapers and concluded that these virus-laden materials will present a potential
threat to the health of those who handle the municipal solid waste.
Since most municipal solid waste will contain some disposable diapers and
other fecal animal wastes, it would be expected that associated emissions, such
as the ADS and HM, would contain some virus and might therefore present a poten-
tial hazard.
Although it can be concluded that a potential hazard (due to virus emis-
sions) may exist, it is evident that additional testing of the ambient air in
and around the plant will be necessary in order to evaluate the potential hazard
in terms of increased virus (and bacteria) levels in the ambient air caused by
processing plant operations.
Future plants of this type will need to control ADS particulate emissions,
and every effort should be made to minimize worker exposure to the bacterial-
and viral-contaminated emissions.
Cost of Environmental Control for Particulate Emissions
Particulate emission measurements and other considerations have indicated
a need for control of ADS emissions. Control of these emissions has been con-
sidered at other facilities, and fabric filters appear to be a feasible control
technique which should provide very high removal efficiency. In fact, a small
filter system was installed at the U«E« power plant for control of emissions
from the Atlas bin when RDF is transferred into the bin from the receiving
building.
88
-------
The ADS system at the St. Louis processing plant is not equipped with any
control device other than a settling chamber, but personal contact with one manu-
facturer has indicated that the FOB cost of a suitable filter, handling 14.2 m-Vs
(30,000 cfm), would be about $60,000, and total installed cost would be about
$100,000.
Use of a fabric filter for control of emissions from the ADS cyclone would
require materials to resist internal condensation problems (galvanized metal or
coated surfaces), and the bags would have to be resistant to rot and mildew.
The filter system would also probably be of modular design for shaker type auto-
matic cleaning with special attention to design of inlet manifolds, and to hopper
angles and removal techniques, etc., in order to avoid bridging problems. Simple
equipment that is as maintenance free as possible would be recommended. Fabric
filters generally require about 1 kPa (4-in. W,C«) pressure drop, which must be
taken into account in specifying the ADS fan.
WATER EFFLUENTS
The only liquid effluent from the processing plant occurs from periodic
washdown of the asphalted processing area of the plant (not including the floor
of the raw refuse receiving building). This cleanup effort removes dust and set-
tled particles, much of which occurs due to blowoff from conveyor belts and ADS
cyclone emissions. It was of interest to determine the quantity and character of
runoff from this washdown activity.
During the first period of air emission tests (November 18 to 22, 1974),
two washdowns took place—one on November 20, 1974, and another 2 days later
on November 22, 1974. The test procedure used during these periods was to de-
termine the quantity of water being used over the length of the washdown pe-
riod (~ 1 hr) and to collect samples of the runoff at various points around
the washdown area. These samples were composited in one container and a por-
tion of this composite sample, as well as a sample of the raw water, was an-
alyzed.
A tabulation of the data obtained for the two washdown periods is pre-
sented in Table 29. These data show that the washdown rate was about 2.2 liters/s
(35 gal/min), and total runoff was about 6,000 liters (2,000 gal.). Comparison
of analysis data for the raw water and the runoff indicates a large increase in
TSS as expected. There was also a significant increase in BOD and COD. However,
the effluent quantity of approximately 6,000 liters (2,000 gal.) seems relatively
small, considering the fact that it occurs only one or two times per week.

A second pair of washdown tests were also carried out in July 1975, and
results are included in Table 29. The primary purpose of this second pair of
tests was to determine bacterial levels in the runoff samples. It is evident,
from the data in Table 29, that there were large increases in the total bac-
teria and fecal coliform levels in the washdown effluent. However, analysis
of raw river water samples (which were obtained in conjunction with tests at
the power plant) showed that the bacteria levels in the river itself may range
as high as 840,000 counts per milliliter with fecal coliform levels up to
110,000 MPN/100 ml. It would appear that although the bacteria levels in the
washdown effluent are quite high, they may not be especially significant since
they are on about the same order as levels that may occur in the nearby river
water at this location.
ASSESSMENT OF LEACHABILITY OF PRODUCTS FROM THE REFUSE PROCESSING PLANT
Operation of the City of St. Louis refuse processing plant in conjunction
with combined firing of coal + refuse in a Union Electric Company utility
boiler results in four materials that could be landfilled: fly ash, bottom
ash, magnetic belt rejects, and RDF. Boiler fly ash is normally sold, but oc-
casionally it may be landfilled when markets are not available. Boiler bottom
ash (sluice solids) is always removed hydraulically from the boiler and de-
posited in an impoundment area where the solids settle out and the overflow
effluent is discharged into the Meramec River. Refuse derived fuel (RDF) is
normally combined with coal as fuel input to the boiler. However, in the event
of boiler maintenance downtime, RDF may be landfilled. The magnetic belt re-
jects, which are the air density separator (ADS) heavy fraction less the mag-
netic metal, are always landfilled at the City of St. Louis operated landfill
adjacent to the processing plant.
It is important to know what constituents might be leached from these ma-
terials which could contaminate surface water or groundwater. For this reason,
samples of the four landfill materials were subjected to a series of tests to
identify potential leachate problems. Details of the tests and the results are
presented next.
Sample Preparation
Procedures for assessing leachability of materials are only in the devel-
opmental stage and methods utilized were based on techniques suggested by knowl-
edgeable personnel at EPA laboratories in Cincinnati, Ohio. Samples of the fol-
lowing four materials were obtained.
91
-------
From Union Electric Meramec Power Plant Unit 1:
Fly ash: coal + refuse
Sluice solids (bottom ash): coal + refuse
From City of St. Louis Processing Plant:
52 - cyclone discharge: (RDF)
S5 - magnetic belt rejects
These four samples were delivered to the Ralston Purina Company Research
900 Laboratory. Standard sample preparation procedures for refuse samples were
used, which means that each sample was dried and then ground to a fine powder
using a laboratory mill. The sample powder was then immersed in distilled wa-
ter for 2 days (48 hr). The samples were continuously agitated during that pe-
riod by means of a laboratory shaker table. At the end of the 2-day period, the
amount of material leached away was determined by drying and reweighing the
solids, and the liquid (leachate) was chemically analyzed. The fact that ground
samples were used should allow maximum leaching to occur within the 2-day test
period because of increased sample surface area.
The S5 sample contained 37.1% metal, which was too high an amount to be
ground by the laboratory grinder; therefore, the metal fraction was hand sep-
arated, not ground, and processed as a separate sample. Metal content of 37.1%
for S5 is higher than average (25.6%) but well within the range of daily values
reported for the 1-year test period.
All of the sample material was completely saturated with distilled water
to the point where excess water existed. The distilled water to sample material
ratio used was 2:1 except for RDF. Due to its light, fluffy nature, RDF com-
pletely absorbed twice its weight in distilled water. Therefore, a distilled
water to sample material ratio of 6.67:1 was used to completely saturate the
sample and result in excess water.
The main concern regarding landfill leachate is contamination of ground-
water that may find its way into the drinking water supply. Therefore, the
leachate was analyzed for materials for which national drinking water standards
have been set plus BOD and COD. Also, nitrite levels were determined because
nitrite could be oxidized into nitrate if the correct conditions are present.
Laboratory Results
The laboratory results obtained are presented in Table 30. Analysis of a
blank sample of distilled water yielded no constituents found within the low
level detection ability of the laboratory methods.

-------
As expected, the metal fraction of the magnetic belt reject sample added
little to the leachate except for BOD. Leachate from RDF had the highest COD
and BOD.
Comparisons to drinking water standards for the leachate produced by the
particular extraction dilutions used in the laboratory procedure are shown in
Table 31. Unfortunately, the drinking water standard limits are below the de-
tection ability of the laboratory procedures for arsenic, cadmium, chromium,
lead, and mercury. In analyzing these data, it was assumed that the "less than"
values reported (Tables 30 and 31) are the maximum values that could exist. All
comparisons are made utilizing this maximum value assumption.
The drinking water standards were exceeded in the laboratory produced
leachate solutions for all elements except nitrate, cyanide, and silver in all
samples; and barium in sluice solids and KDF.
Nitrites were at low levels. Therefore, even if they were all converted
to nitrate, it would not significantly change the reported nitrate levels.
The nonmetallic fraction of S5 does exceed the nitrate standard. However,
when it is combined with the metallic fraction, the nitrate concentration is
below the standard.
Comparisons and Evaluation of Results
The statement that drinking water standards were or were not exceeded per-
tains specifically to leachate from the extraction dilutions used. Also, the
RDF dilution was much higher than the others. The various constituent levels
of RDF leachate cannot be converted to the lower dilution ratios used for the
other samples. At lower dilution levels, RDF simply absorbs the water, and it
is doubtful how much leachate would result.
Any of the constituents in any of the samples could be lowered to the
drinking water standards if a high enough dilution ratio were used. To obtain
a better comparison, each leachate constituent level was converted to grams
per megagram (Ib/ton) of material by the following formula.
Grams of a constituent removed by leaching per megagram of material —
(mg/liter constituent level) (ml distilled water/g of sample)
(1,000 mg/g) (1,000 ml/liter) (Mg/1 x 10° g)

The above equation was used to calculate the results shown in Table 32,
These results represent the amount of each constituent which is removed by
leaching, regardless of the extraction dilution ratio used. The next step in
evaluating the data was to make a ranking of each constituent level according
to the drinking water standards. This was accomplished by calculating the
liters of water per megagram (gallons per ton) that would be necessary to di-
lute a constituent to drinking water standards by the following formula.
Liters per megagram of dilution water needed —
g/Mg constituent level removed by leaching
rag/liter drinking water standard (g/1,000 mg)
(Gallons per ton of dilution water needed =)
Rib/ton constituent level removed by leaching)]
L (Ib/gal. drinking water standard) J
Results of this calculation are shown in Table 33, Interpretation of the
relative magnitude of these results was done in two ways. First, by comparing
the amount of dilution required first between elements within a sample, and
second, by comparing the amount of dilution required between samples for a
given constituent. Table 34 depicts the ranking from highest to lowest dilu-
tion required to meet the drinking water standards for each constituent within
a given sample. Nitrates and cyanide consistently ranked as the two lowest con-
stituents. Selenium ranked highest with mercury second highest for all samples
except sluice solids which contained no selenium and had mercury ranking highest.
The most important conclusion is as shown in Table 33. Selenium in all the
samples except sluice solids had much higher dilution requirements than any of
the other constituents. Also, as shown in Table 30, the levels of selenium found
in the laboratory dilutions were above the detection ability of the laboratory
methods. Therefore, the dilution required for selenium to meet the drinking water
standards is not prejudiced by the necessity of assuming the actual level to be
that of the laboratory procedure detection level (as was done for many of the
other constituents).

Ranking of the four samples for dilution required per constituent is shown

highest for nitrates and fly ash ranked highest for barium. The other samples
were mixed in ranking or no clear trends were present.
Suggestions, for Future Work
The leachate produced for these tests was the result of only a single set
of laboratory test conditions. Therefore, it might be well to investigate the
effects of immersion time, agitation, and amount of extraction dilution. Also,
distilled water was used for these tests, but some literature sources report
acid or basic pH in landfilled leachate. Therefore, more work may be needed to
determine the effects of pH on leachate production. Further work is also needed
to compare leachate produced in the laboratory with leachate from a landfill,
and to compare coal-only fly ash and sluice solids leachate with coal + refuse
leachate.
Another area of study is related to the fact that in St. Louis the raw mu-
nicipal refuse is a raw material which may be landfilled following various pre-
treatment methods. First, raw refuse may be landfilled, producing raw refuse
leachate, which is the case for many of the suburban areas adjacent to the City
of St. Louis. Second, raw refuse may be incinerated and the incinerator bottom
ash landfilled, producing incinerator ash leachate. This is currently the pro-
cedure used by the City of St. Louis except for that portion of the collected
refuse routed to the processing plant. Thirdly, raw refuse may be processed at
the City of St. Louis Refuse Processing Plant. Here two situations may be pres-
ent. Normally, when the Union Electric boiler is in operation, leachate would
be from magnetic belt rejects, boiler sluice solids, and possibly fly ash. If
the boiler is not in operation, then leachate would be from magnetic belt re-
jects and RDF. Therefore, additional work is needed so that comparisons can be
made between leachate from raw refuse, incinerator bottom ash, and the process-
ing plant and utility boiler landfilled materials. Such information would greatly
aid in the total environmental assessment of each of the three methods of munici-
pal refuse disposal.
Following is a summary of areas recommended for further study.
1. Effect of laboratory extraction dilution - ml liquid/g of sample (gal.
liquid/lb of sample).
2. Effect of laboratory extraction liquid pH.
3. Effect of laboratory immersion time (number of days in extraction
liquid).
4. Effect of laboratory agitation (shaker table versus none).

SOUND SURVEY
Another environmental consideration for operations at the processing plant
was noise levels, especially that associated with the 932.5 kW (1,250 hp) grinder.
Since noise levels were of concern, a sound survey was carried out that included
analysis of noise levels at several locations in and around the plant. The test
procedures for this sound survey and evaluation of the results are discussed next.
Test Procedure
The following General-Radio test equipment was used for the sound survey.
Model 1558 DP Portable Octave Band Noise Analyzer;
Model 1560 Pb One Inch Ceramic Microphone; and
Model 1562 A Calibrator.
The noise analyzer with microphone was calibrated each day of the sound
survey. Meter response range was 44 to 150 decibels (dB). A zero meter response
was listed as < 44 dB. The portable analyzer was hand-held, and the microphone
was placed 1.4 m (4.5 ft) above grade at each measurement location.
Sound levels in decibels at slow meter response were measured at 10 octave
bands plus the A scale (dBA). The octave band measurements show the overall
sound spectrum in terms of decibels versus frequency. This information will be
useful for acoustical engineering, land use zoning, and other activities related
to the total sound spectrum produced. Octave bands used are as follows:
101
-------
OCTAVE BANDS USED
Frequency (Hz)
Octave band No» Band center Lower cutoff Upper cutoff
1 31.5 22.3 44.6
2 63 44.6 89.2
3 125 88.4 177
4 250 177 354
5 500 354 707
6 1,000 707 1,414
7 2,000 1,414 2,820
8 4,000 2,828 5,656
9 8,000 5,656 11,310
10 16,000 11,310 22,620
The A scale sound levels will be useful to those interested in O.S.H.A.
applications. (O.S.H.A. regulations are defined in terras of dBA measurements.)
Measurements were made (a) when the plant was conducting normal prepara-
tions, and (b) when the plant was not operating, to identify the levels of usual
background noise. Any sound measurements of operating equipment will be the com-
bination of the sound produced by the equipment plus the background sound. For
the City of St. Louis Refuse Processing Plant, the background sound sources con-
sist of the following.
Location of Background Sources
Background source Direction from plant
Interstate Highway 55 West
Mississippi River East
City Incinerator North
City Truck Maintenance Garage Southwest
Table 36 lists the measurement locations. Sixteen locations were used to
monitor noise levels in the following three general areas.
1. Employee work areas (Locations 1 through 8).
2. Light sound level equipment areas (Locations 9 through 11).
3. Sound levels along processing plant perimeter (Locations 12 through 16),

Sound Survey Results
Tables 37 and 38 list the sound measurement results. The background sound
is relatively low, being less than 60 dB above 250 Hz center band frequency.
The major background is low frequency sound from adjacent Interstate Highway
55. The major sound from the processing plant is in the lower frequencies; the
hamraerraill, nuggetizer, ADS fan exhaust, front-end loader, and raw refuse trucks
are the principal contributors.
Location 7 had the highest sound level in the upper frequencies. This loca-
tion was closest to the working mechanisms of the nuggetizer, and also underneath
the metal nuggetizer feed chute. This feed chute receives the magnetic metal from
the magnetic separator belt, and its sound production is primarily due to the
metal particles striking the metal chute. Both the nuggetizer and the magnetic
belt are acting together to produce higher sound levels in the 1,000 to 8,000 Hz
center band frequencies.
Location 4.1 is with the front-end loader working at maximum load. Location
5 shows that, with the operator's cab doors closed, the cab is reducing the en-
gine sound except for center band frequencies 31.5 and 250 Hz, Fortunately, these
frequencies do not have a full effect on the A scale, and the dBA is below the
O.S.H.A. limit of 90 dBA.
Location 4.2 is inside the receiving building at the same physical point
as 4.1. These measurements are highest when the raw refuse trucks discharge ref-
use onto the building floor. These refuse trucks are not dump trucks with a tilt-
ing truck box. Instead, the trucks utilize a mechanism which rapidly shakes the
cargo compartment to discharge the raw refuse. Measurements were taken during
the shaking action. However, this action lasts for only a few seconds per truck.
The current— O.S.H.A. regulations specify a maximum of 90 dBA for continu-
ous 8-hr exposure, with shorter allowable time limits at levels above 90 dBA.
No operator must spend a full work day at any location above 90 dBA* Locations
above 90 dBA are shown in Table 39.
The time that an individual employee may spend in these locations when the
equipment is operating is estimated to be less than the allowable time exposure.
Also, at Locations 4.1 and 4.2, the front-end loader is at maximum load only a
portion of the total operating time.

Heat energy (kj x 106) calculated from daily heating value (kj/kg) times daily weight (kg)
for test days when daily samples taken. During test period when only veekly composite
samples were taken (weeks 9 through 23) heat energy calculated from weekly composite heat-
ing value and weekly total weight.
b/ Heating value of magnetic drum rejects not determined. Calculated energy loss therefore
includes magnetic drum rejects.
c/ Samples not taken. Therefore, no heating value data available.

a/ Megagrams of magnetic metal calculated from weekly sum of dally percent ferrous metal times
dally weight (Mg) for test days when daily samples were taken. During test period when
only weekly composite samples were taken (weeks 9-23) recovery calculated from weekly
composite percent ferrous metal and weekly total weight. Weighted average percent fer-
rous metal would be weekly megagrams ferrous metal divided by total weekly megagraros.
b/ Assumes 86.37. magnetic material. Samples not taken of stream S7.
cj -Samples not taken. Therefore no percent magnetic metal available.

APPENDIX C
ENVIRONMENTAL TEST PROCEDURES AND DATA
TEST PROCEDURES FOR AIR EMISSION SAMPLING
Visual observation of the effluent from the ADS cyclone had indicated that
it contained some large particles (pieces of paper, etc.) and was perhaps one
of the more significant sources of debris that occurs in and around the plant.
However, some windblown debris also undoubtedly occurs from the semi-enclosed
conveyors and spillage from loading of packer trucks, etc.
Since it was obvious that the ADS cyclone discharge contained these large
particles, it was considered impractical to sample the effluent using EPA Method
5 sampling trains because the small probe tips that are required would very likely
be plugged by the large particles. The same would have been true for the cascade
impactors that are usually used to determine particle size distribution of partic-
ulate matter in effluent streams. Therefore, it was necessary to utilize high vol-
ume sampling techniques with their larger probes about 25-mm (1-in.) diameter.
Both a high volume mass train and high volume cascade impactor, equipped with a
precyclone, were provided by EPA for this work.
ADS CYCLONE TEST PROCEDURES
Sampling of the ADS cyclone discharge was carried out in the 1.07-m (42-in.)
diameter horizontal duct at the inlet to the ADS fan as shown in Figure C-l. Two
102-rnm (4-in.) diameter sampling ports had been installed in the top and side of
this duct. The nearest flow disturbance, relative to the sampling ports, was five
duct diameters upstream (a 90-degree elbow) and two diameters downstream (air flow
control vanes and fan).
Particulate sampling of the emissions from the ADS cyclone was carried out
with a high volume sampler of approximately.0.007 TOT/S (15 cfm). Sampling was con-
ducted using a 23-ram (0.91-in.) diameter probe tip and sampling for 2 min at 14
points along each of the two duct traverses. Configuration of the mass sampling
equipment is shown in Figure C-2. Isokinetic sampling was carried out, but it was
necessary to determine the proper sampling rate based on a preliminary velocity
traverse.

Note:
A preliminary velocity traverse was made of gas flow
in duct in order to determine proper sampling rate at
each sample point. Average sampling rate was about
0.007rr,3/s
During tests at Hammermill Cyclone,heated probe and
filter holder were used, along with Ice cooled
condenser preceeding the orifice.
Figure C-2. Diagram of particulate mass sampling equipment
-------
Particle size distribution of the ADS cyclone discharge was determined us-
ing the Anderson Hi-Volume cascade impactor and precyclone provided by EPA as
depicted in Figure C-3. A 29-mm (1.125-in.) diameter probe tip was used and the
sampling was conducted for 30 min at a single point near the center of the duct.
HAMMERMILL CYCLONE TEST PROCEDURE
Sampling of the hammermill cyclone discharge was carried out in a 0,3-m
(12-in.) diameter vertical duct extension equipped with two sampling ports 90
degrees apart* The end of this duct extension was two duct diameters downstream
of the sampling ports and there were in excess of 10 duct diameters upstream of
the ports before any flow disturbance.
Particulate sampling of emissions from the HM cyclone was carried out using
the same equipment as for sampling of the ADS system (see Figure C-2). The only
differences were the selection of the 29-mm (1.125-in.) diameter probe tip and
use of the probe heater, heating jacket for the filter holder, and moisture trap
ahead of the orifice, in order to minimize problems due to high moisture content
of the effluent stream. Sampling was con ucted for 5 min at four points along
each of the two duct traverses. Again, sampling rate at each point was based on
a preliminary velocity traverse.
Particle size distribution tests on the HM cyclone discharge were done us-
ing the same high volume cascade impactor used for sampling the ADS system (Fig-
ure C-3). The 29-mm (1.125-in.) diameter probe tip was used and the sampling was
conducted for 1 hr at a single point near the center of the duct. However, be-
cause of the high moisture content of this stream, the heated probe and heating
jacket for the impactor were used.
The effective cutoff for the impactor stages are noted in the attached ta-
bles. In considering these values, it was assumed that the cutoff diameter for
the precyclone was ~ 10 |J.m. However, the cutoff diameter for the impactor stages
strictly applies only to spherical particles of density 1.0, which undoubtedly
is not the case for the particles in these effluent streams. In this regard,
visual inspection of the material caught on the mass train filter and in the
precyclone showed much of it to be of a fibrous linty nature, similar in appear-
ance to material collected in a household vacuum cleaner. Small pices of paper
and plastic approximately 25 mm by 25 mm (1 in. by 1 in.) in size were also ob-
served.
Bearing in mind the considerations discussed above, it is significant to
note that the data indicate that most of the particulate matter (> 80%) was
caught in the precyclone.

HAZABDOUS TESTS
Mass emission test data for the July 1975 hazardous tests were not tabu-
lated as in previous tests because samples were split in the field for bacteria
and virus analysis. No particle size tests were conducted during the July 1975
tests* Procedures for hazardous tests are contained in the body of this report
under the section entitled "Potentially Hazardous Air Emissions."

APPENDIX D
STATISTICAL EVALUATION OF PROCESS STREAM SAMPLES
It was realized that the sampling methodology for characterizing the pro-
cess streams might involve considerable error and not yield representative re-
sults. Therefore, a statistical evaluation of certain data was performed. The
methods used to perform these statistical evaluations and the results are dis-
cussed in the following paragraphs.

-------
STATISTICAL DIFFERENCE BETWEEN REFUSE FUEL ENTERING
AND LEAVING THE STORAGE BIN
The daily sample analysis results for the 10-day period of September 23
through October 4, 1974, of refuse fuel entering the storage bin (S2) and ref-
use fuel leaving the storage bin (S3) were subjected to statistical analysis.
At 95% statistical confidence coefficient, there was no significant dif-
ference between S2 and S3 for any of the sample spectrums except bulk density.
The bulk density data were reanalyzed and found to be significantly higher in
S3 even at 99% confidence coefficient.
Bulk density is higher in the storage bin discharge due to the bin packing
factor. Weight of material in the bin causes material compaction at the lower
bin elevations. Since the bin was designed to discharge the material at the bin
bottom, this discharged material is always more compressed and has a higher kg/
m^ (lb/ft3) bulk density than the material entering the bin from the top.

SAMPLE VARIABILITY
Two tests were performed to determine sample variance. First, eight subsam-
ples evenly spaced over a 2-hr period were taken of the milled raw refuse (SI)
and the cyclone discharge (S2). Second, eight subsamples evenly spaced over a 1-
hr period were taken of the refuse fuel entering the storage bin (S2) and leav-
ing the storage bin (S3). Each individual subsample was analyzed. The individual
results are shown in Appendix B (Table B-8).
The sample results were subjected to statistical analysis. It was determined
that there was no significant difference in sample variability between samples
taken over a 1-hr interval and those taken over a 2-hr interval. Whatever short
term time trends may be present, they do not affect the variability or dispersion
of the sample data.
Daily samples of the various plant refuse streams were composed of four sub-
samples taken at 2-hr intervals which were composited to form one daily sample
that was inspected and analyzed. Daily sample results are therefore the mean of
four subsamples. The precision of such a mean can be calculated from the pooled
sample variance of the previously mentioned test data listed in Table B-8. Table
23 shows the variability for each analysis spectrum category based on 95% con-
fidence coefficient for a sample size of four. In general, the data in Table 23
indicated that results obtained by the normal sampling method (i.e., sample size
of four) could be expected, with 95% confidence, to be within + 10 to 15% of the
actual mean value for most analysis spectra (e.g., heating value, moisture, etc.).

16. ABSTRACT xhis report presents the results of processing plant evaluations of the
5t. Louis-Union Electric Refuse Fuel Project, including equipment and facilities as wel]
is assessment of environmental emissions at both the processing and power plants. Data
>n plant material flows and operating parameters, plant operating costs, characteristic
f plant material flows, and emissions from various processing operations were obtained
luring a testing program encompassing^53 calendar weeks.
lefuse derived fuel (RDF) is the major product (80.6% by weight) of the refuse process-
ing plant, the other being ferrous metal scrap, a marketable by-product. Average
Derating costs for the entire evaluation period were $8.26/Mg ($7.49/ton). The average
iverall processing rate for the period was 168 Mg/8-hr day (185.5 tons/8-hr day) at
51.0 Mg/hr (34.2 tons/hr).
"uture plants using an air classification system of the type used at the ST. Louis
lemonstration plant will need an emissions control device for particulates from the
.arge de-entrainment cyclone. Also in the air exhaust from the cyclone were total
:ounts of bacteria and viruses several times higher than those of suburban ambient air.
k> water effluent or noise exposure problems were encountered, although land-fill
Leachate mixed with groundwater could result in contamination, given low dilution rates
