Description:

Chem-Pruf Door manufactures fiberglass reinforced plastic doors, frames, windows and industrial louvers. Chem-Pruf Door has implemented a strategy to minimize all wastes or chemical releases from their operations. A major portion of its wastes are non-hazardous process wastes sent to a landfill. Chem-Pruf Door developed a program to collect all non-hazardous fiberglass reinforced plastic (FRP) wastes and reuse them in finished products. Proper mixing and batch sizing are emphasized to minimize waste generation. Any excess resin generated during mixing and molding is collected in containers. Vacuum systems collect dust from all grinding and cutting tools. Dust, accumulating on the floors, is collected daily and not allowed to become contaminated with other materials. Oversized scraps are crushed to the proper size. Over 90% of all FRP raw materials go into finished products.

P2 Application:

Chem-Pruf Door developed innovative processes to reuse process wastes in their production operations. Its basic products were analyzed to determine how and where process wastes could be effectively utilized. Processes were then developed to convert the wastes into quality feedstocks for reuse.

Environmental Benefits:

Chem-Pruf Door Co. has reduced the quantity of non-hazardous waste being landfilled from over 100,000 pounds to less than 20,000 pounds per year. It has converted over 74% of their previous waste materials into finished products.

Details of Reductions

Additional Information :

Chem-Pruf Door had to purchase a crushing machine, a slitter machine and dust collection equipment. It has increased its FRP raw material utilization rate to over 90%. Material cost savings off-set daily system operations.
