Description:
The U.S. Environmental Protection Agency (EPA) funded a project with the New Jersey Department of Environmental Protection and Energy (NJDEPE) to assist in conducting waste minimization assessments at thirty small- to medium-sized businesses in the state of New Jersey. ne of the sites selected was facility that manufactures plastic containers by injection molding. he manufacturing process involves melting of a plastic resin and injection of the melt into molds in the shape of the container to be manufactured. he cooled and solidified container is removed from the mold, the mold is cleaned with solvent when required and the injection process is repeated. ortion of the containers are also made by blow molding which involves use of compressed gas to move the resin melt onto the walls of the mold. he rest of the operation similar. ite visit was made in 1990 during which several opportunities for waste minimization were identified. ptions identified for a facility such as this included change in equipment to eliminate use of hydraulic oil, change in mold cleaning procedures, and modifications to metal machining operations. t should be pointed out that this facility had already initiated an aggressive pollution prevention program.
