Site Name: Boehringer's Lindane Facility (Non-NPL)
Location of Test: Vest Germany
BACKGROUND; In August of 1986, Shirco was contracted by Dekonta GmbH, a
Vest German hazardous waste treatment company, to perform treatability
studies at one of the largest dioxin-contaminated sites in the world. The
Shirco Infrared process was selected by Dekonta after a two year study and
evaluation of existing and emerging technologies for soils decontamination.
The Vest German hazardous waste management regulations, which are
established and enforced on a state by state basis, differ somewhat from
those in the US. Transportation of dioxin-bearing wastes, for instance, is
strictly prohibited. Hence, mobile technologies offer distinct advantages
for multiple site remediation.
OPERATIONAL INFORMATION; Tests were conducted using the Shirco Portable
Demonstration Unit during the months of November 1986 and February 1987.
Over 3000 kg of contaminated soil were processed in 100 hours of testing.
Various operating condition's including soil contaminant level, feed rate,
primary chamber temperature and residence time, co-flow and counterflow
operation, and gas atmosphere (air vs. nitrogen) were tested to determine
the effect on soils decontamination levels and exhaust gas emissions. The
organic contaminants in the soils included dioxins, furans, chlorobenzenes,
chlorophenols, 2,4,5-T, and hexachlorocyclohexanes. Contaminant concen-
trations on soils ranged from 4 to 7500 ppb for dioxins, 3 to 5700 for
furans and from 33 to 16,600 ppm for chlorobenzenes. No QA/QC data was
presented.
PERFORMANCE; Results of approximately 20 tests indicate exhaust gas con-
centrations of 2,3,7,8 TCDD from less than 20 pg/m to 88_pg/m , whereas
field "blanks" showed concentrations ranging from 33 pg/m to 73 pg/m .

The source of the high blank concentrations is currently under investi-
gation, therefore, the validity of the reported values cannot be estab-
lished at present. A brief summary of the data is on the attached table.

-------
In August of 1986, Shirco was contracted by Dekonta GmbH, a West
German hazardous waste treatment company, to perform treatability
studies at one of the largest dioxin-contaminated sites in the
world. The Shirco Infrared process was selected by Dekonta after
a two year study and evaluation of existing and emerging
technologies for soils decontamination.
The West German hazardous waste management regulations, which are
established and enforced on a state by state basis, differ
somewhat from those in the US. Transportation of dioxin-bearing
wastes, for instance, is strictly prohibited. Hence, mobile
technologies offer distinct advantages for multiple site
remediation. Notable regulations for hazardous waste
incineration in the State of Hamburg include the following stack
gas limitations:
Particulate Matter:
CO:
SO :
HC1:
TOG:
2,3,7,8 TCDD:
30 mg/dscm
100 mg/dscm
100 mg/dscm
50 mg/dscm
20 mg/dscm
100 pg/dscm
Required soils treatment levels include a 1 ppb 2,3,7,8 TCDD
standard; other organic compounds must be reduced to levels
compatible with US EPA "listing" guidelines.
Note that the stack gas standards do not include a destruction
and removal efficiency (DRE) requirement. Rather, the standard
stipulates a single maximum exhaust gas concentration which must
be satisfied regardless of feedstock concentration or feed rate.
This "zero" emission standard (which also affects byproduct
emissions from chemical manufacturing facilities) along with the
transportation prohibition for dioxin-bearing wastes and publin
and political pressure, resulted in the closure of Boehringer's
lindane production facility in Hamburg. This site, with an
estimated 80,000 cubic meters of dioxin-contaminated soil, was
the focal point of this treatability study.
Tests were conducted using the Shirco Portable Demonstration Unit
during the months of November, 1986 and February, 1987. Over
3000 kg of contaminated soil was processed in 100 hours of
testing. Various operating conditions including soils
contaminated level, feed rate, primary chanber temperature and
residence time, co-flow and counterflow-operation, and gas
atmosphere (air vs. nitrogen) were tested ta^deterraine the effect
on soils decontamination levels and exhaust gas emissions. The
organic contaminants in the soils included dioxins, furans,
chlorobenzenes, chlorophenols, 2,4,5-T, and
hexachlorocyclohexanes. A brief summary of the soils
decontamination data is presented in the attached table.
-------
Results of approximately 20 tests indicate exhaust gas
concentrations of 2,3,7,8 TCDD from less than 20 pg/m3 to 88
pg/m3 / whereas field "blanks" showed concentrations ranging from
33 pg/m3 to 73 pg/m3. The source of the high blank
concentrations is currently under investigation, therefore, the
validity of the reported values cannot be established at present.
Upon completion of the Hamburg test program, the unit was moved
to Ingelheim, West Germany to continue soils treatability tests
at Boehringer's active facility. Three test series were
conducted during the months of March, May and June, 1987. A
final report for both the Hamburg and Ingelheim test programs
will be issued upon completion of all analytical work.
