NYS Governor's Awards for Pollution Prevention - Crosman

Crosman Corporation, East Bloomfield, NY

Background

The world's largest manufacturer of air powered rifles, pistols and associated accessory items, Crosman employs approximately 350 people at its East Bloomfield, New York production facility.

Once producing 311 tons of hazardous waste a year, Crosman Corporation is now well on its way to becoming a hazardous waste free facility. Crosman has reduced its annual generation of hazardous waste by more than 280 tons, while increasing its overall production 130 percent.

Methodologies and Procedures

Lead dust generated during production of lead pellet ammunition was originally removed using an aqueous alkaline wash solution. However, chelating agents in the soap which solubilized the lead left a massive and costly hazardous waste stream. Alternatively, pellets are now placed in a dry vibratory bowl under a vacuum exhaust which draws the lead dust into a bag filter system. The collected dust along with scrap generated from the forming process is then returned for recycling to the firm which supplies Crosman with its lead wire. This new method of operation has eliminated the generation of hazardous waste by 250 tons annually.

Further reductions in the generation of hazardous waste (30 tons per year) were realized as the facility switched to a non-hazardous parts washing solvent and installed self-contained sink units and a solvent/waste oil separation filter.

In an effort to eliminate the use of ozone-depleting trichlorotrifluoroethane (Freon), Crosman experimented with trichloroethylene (TCE) degreasers already being used to clean production materials manufactured from carbon steel. It was determined that TCE would sufficiently clean the brass valve bodies and allow for decommissioning of the Freon vapor degreaser. This step eliminated CFC emissions by 8,400 pounds per year.

However, when TCE was identified as a significant generator of hazardous waste and air emissions, Crosman analyzed its use and found that all four of its degreasing operations could be addressed through the use of specifically designed aqueous systems and just-in-time production practices which enabled parts received from outside vendors to be shipped without an oil finish. The rewards were evident as Crosman's generation of hazardous waste decreased by 25 tons per year and its TCE emissions by 50 tons per year.

Crosman has shown its commitment to pollution prevention in all forms, including the handling of non-hazardous solid waste. Of the 1,601 tons of solid waste generated from production processes in 1994, 1,465 tons (92 percent) were recycled or reused.

Benefits

The generation of hazardous waste has been reduced by 90 percent, despite an overall increase in production of 130 percent.

CFC emissions have been reduced by 8,400 pounds per year.

TCE emissions have been reduced by 50 tons per year.

Potential liability has been lessened, and worker safety and community relations improved through a reduction in the quantities of hazardous materials stored on-site, managed and used.

Economic benefits have been realized by the elimination of hazardous waste disposal and spill prevention program costs, as well as reduced regulatory fees, taxes and reporting requirements.
