                                       THE 33/50 PROGRAM
     This Company Profile is pan of a senes of reports being developed by EPA to highlight the accomplish-
 ments of companies participating in the 33/50 Program.  The 33/50 Program is an EPA voluntary pollution
 reduction initiative that promotes reductions in direct environmental releases and offsite transfers of 17 high-
 priority toxic chemicals.  The program derives  its name from its overall goals  an interim goal of a 33%
 reduction by 1992 and an ultimate goal of a 50% reduction by 1995.  The program uses 1988 Toxics Release
 Inventory (TRI) reporting as a baseline.  In  February,  1991, EPA began contacting the parent companies of
 TRI facilities that reported using 33/50 Program chemicals since 1988 to request their participation in  the 33150
 Program.  As of April, 1994, a total of 1,216
 companies  had elected to participate in the
 Program, pledging to reduce emissions of the 17
 target chemicals by more than 355 million
 pounds by 1995.  Companies are encouraged to
 set their own reduction targets, which may vary
 from the Program's national 33% and 50%
 reduction goals.  Company commitments and
 reduction pledges continue to be received by
 EPA on a daily basis.

    The 1992 TRI data revealed that releases
 and transfers of 33/50 Program chemicals de-
 clined by 40% between 1988 and 1992, surpass-
 ing the Program's 1992 interim reduction goal
 by more than 100 million pounds.  This accom-
 plishment, together with evidence from analysis
 of facilities' projected releases and transfers of
 the 17 priority chemicals, reported to TRI under
 the Pollution Prevention Act, offers strong en-
 couragement that the 33/50 Program's ultimate
 goal of a 50% reduction  by 1995 will be
 achieved.

33/50 Program Company Profile:  Aldan Rubber Company

-------
                         Aldan Rubber Company
    Aldan Rubber Company reduced its releases of
 transfers of 33/50 Program chemicals by 1,011,460
 pounds from 1988 to 1992, a reduction of 73%.  In
 addition, according to data from the  company's
 33/50  Program progress reports, Aldan  further
 reduced emissions by 168,010 pounds in 1993. As
 a result Aldan has surpassed its program goal of an
 80 percent reduction in releases and transfers of
 33/50 Program chemicals.

       I. CORPORATE BACKGROUND

    Aldan Rubber Company is a manufacturer of
 rubber-coated  fabrics  that are used  in  a wide
 variety of applications, including protective cloth-
 ing for  fire  fighting,  flexible  duct connectors,
 convertible tops, and  baby  products.   Aldan is
 located in Philadelphia, Pennsylvania.

    Aldan uses two 33/50 Program chemicals in its
 manufacturing operations:   methyl ethyl  ketone
 and toluene. Toluene  has traditionally accounted
 for approximately 95% of Aldan's total releases
 and transfers of 33/50 Program chemicals.
Aldan  viewed participation in the 33/50
Program as a logical extension of the
company's ongoing environmental pro-
tection efforts.
    Toluene is  used as a carrier solvent in the
fabric coating  process.   Rubber is  mixed  with
toluene  to achieve a mixture that can be spread
evenly onto  the fabric being coated.  After the
rubber mixture is spread on the fabric, the toluene
evaporates, leaving a uniform coating of rubber on
the  fabric.   Aldan has also  traditionally  used
toluene  as a solvent in cleaning its manufacturing
equipment. In this application, toluene is manual-
ly wiped onto dirty machine parts to remove excess
rubber, dirt,  and other contaminants.

    Methyl ethyl ketone is also used as  a carrier
solvent in the fabric coating process.  It is needed
in  the  manufacture  of  a small percentage of
Aldan's  products because some types of rubbers do
not dissolve well in toluene.

    Aldan reported 1,388,500 pounds of releases
and transfers of 33/50 Program chemicals in  1988,

all in the form of air  emissions.   These 33/50
Program chemicals accounted for 99.9 percent of
releases and transfers of all TRI chemicals.  Table
I, at the end of this profile, presents Aldan's 1988-
1992 data on releases and transfers of 33/50 Pro-
gram and other TRI chemicals.

    II. CORPORATE ENVIRONMENTAL
                STRATEGY

    Aldan company officials viewed participation
in the 33/50 Program as a logical extension of the
company's  ongoing  environmental  protection
efforts. As early as 1976, Aldan saw the need to
reduce emissions of toxic chemicals.  As a result,
the company installed a solvent recovery system at
its manufacturing plant.  The solvent recovered
was reused in the manufacturing process, and the
system greatly reduced  the amount of toluene
emitted from the facility.   Aldan  believes that
installing the recovery system made sense from an
economic standpoint, noting that resources invest-
ed in the project were paid back through the recy-
cling of greater amounts of solvent.

    III.  33/50 PROGRAM GOALS AND
   POLLUTION REDUCTION ACTIVITIES

    Aldan set an ambitious goal of reducing total
releases and transfers of 33/50 Program chemicals
by 80% from 1988 levels by 1995.  This translates
into a reduction of 1,110,800 pounds. This reduc-
tion was to be accomplished on top of the reduc-

 tions that  Aldan  had  already achieved through
 their earlier solvent recovery activities.   Aldan
 hoped to achieve much of this reduction through
 the on-site recycling and reuse of solvents.
Aldan pledged to reduce releases and
transfers of 33/50 chemicals by 80% by
1995, from 1988 levels.
    Aldan conducted a survey to identify areas in
the manufacturing process where significant emis-
sions were taking place. This allowed the company
to focus reduction efforts on the largest emission
sources.  The survey followed the "solvent trail"
through the  entire  manufacturing process, from
unloading of solvent  from tank trucks to post-
manufacture  disposal  of  rubber scrap.   After
completing the facility survey and evaluating  the
results, Aldan identified five major activities that
would significantly reduce chemical emissions:

   Totally enclose  the rubber spreader.  In  its
    1976 project,  Aldan installed a hood to cap-
    ture solvent emissions over part of its spread-
    er. The captured solvent was then routed to a
    recovery  unit.  Aldan recently enclosed  the
    entire spreader  so  that all solvent  emissions
    are  captured  and  recycled,  rather  than just
    those under the partial hood.

   Renovate  the solvent recovery system.  In
    order to  improve the efficiency of its solvent
    recovery system, Aldan renovated the  system
    put  in place in  1976.  As part of the renova-
    tion, the recovery  unit  received  a  complete
    overhaul, including replacement of the carbon
    recovery  media, cooling coils, and  old seals
    and valves.  Aldan reported the solvent recov-
    ery  unit's efficiency at 98%  - 99% after  the
    renovation, an increase of approximately 20%
    from the  previous efficiency level.

   Use an  alternative cleaner for machinery
    clean-up.  Aldan traditionally used toluene in
    a hand-wipe application to clean its equipment
    on a periodic basis.  This cleaning removes
    excess rubber, dirt, and other contaminants
    from production machinery. To eliminate this
    use  of toluene, Aldan now uses a d-limonene
    cleaner in a  similar hand-wipe application,
    with reduced but satisfactory performance, and
    somewhat higher but still acceptable cost.
    Institute an  employee awareness  program.
    Aldan recognized that a significant quantity of
    solvent emissions could be eliminated simply
    by improving the handling of process materi-
    als. An employee awareness program, manda-
    tory for all employees who  handle  solvents,
    was implemented to achieve this goal. During
    the program,  Aldan explained to  workers the
    environmental problems associated  with the
    solvent emissions and  made suggestions  for
    reducing emissions. Company officials believe
    that the employee awareness program has
    been a great success.
Prior to the implementation of any
reduction  measures, Aldan conducted a
facility survey to identify the largest
sources of chemical emissions.
   Improve management of rubber scrap.  Aldan
    developed a proprietary process by which it is
    able to reduce solvent emissions from rubber
    scrap.  This process is one in which the scrap
    is processed to remove excess solvent prior to
    scrap disposal. Aldan has found that, not only
    does the process reduce emissions of solvent
    to the air, but it also renders the rubber scrap
    nonhazardous.  The scrap  can then  be  dis-
    posed of in a municipal landfill.

     IV. PROGRESS  TOWARDS 33/50
            REDUCTION GOALS

    As a result of the efforts described above, by
1992  Aldan  Rubber  had reduced releases  and
transfers of 33/50 Program chemicals by 73% from
the 1988 baseline, almost reaching its goal of an
80%  reduction.  Reductions  for  toluene alone
accounted for more than 1,000,000 pounds.

    According to information provided by Aldan in
its  progress reports, significant additional reduc-
tions were achieved in 1993.  Releases of toluene
decreased by  an additional  161,895  pounds  and
methyl  ethyl ketone decreased by 5,849 pounds.
This translates into reductions of 45% and 33% re-
spectively from 1992 levels. As a result, Aldan has
achieved an 85% reduction in releases and trans-
fers of 33/50  Program chemicals from 1988 levels,
surpassing its 1995 reduction goal of 80%.

          V. SUMMARY OF ALDAN'S
                 EXPERIENCE

     Aldan  Rubber Company has  been extremely
 successful in reducing its releases and- transfers of
 33/50 Program chemicals.  In total, Aldan achieved
 a reduction of 73% through 1992 for toluene and
 methyl ethyl  ketone,  the company's two 33/50
 Program  chemicals.  In  addition, the company
 reports surpassing its 1995 program goal by achiev-
 ing a total reduction of 85% by the end of 1993.
 Aldan feels that the 33/50 Program has
 been a strong impetus for the company
 to reduce its  VOC emissions.
     Aldan has long been concerned with reducing
 solvent emissions, as evidenced by the installation
 of a solvent recovery system in 1976. However, the
 company feels that "the 33/50 Program has been a
 strong  impetus  for  Aldan  to  reduce its  VOC
 emissions." Aldan views pollution prevention as a
 team effort, and  has found great benefit in involv-
 ing  its  employees  in the  process.  Through  its
 innovative employee awareness program, Aldan has
 educated  its  workers about the environmental
 problems  caused by solvent emissions, and  the
 employees have  responded  with  more careful
 handling of solvents throughout the manufacturing
 process.
