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. One of the sites selected was facility that processes scrap metal to recover refined metals for reuse. The facility concentrates on recovery of tungsten, molybdenum, and tantalum. he processes used by the facility involve washing, degreasing, mechanical cleaning, and acid treatment. Site visit made in 1990 during which several opportunities for waste minimization were identified. Options identified include improved process pH control, changes in solid precipitation technology, and acid reuse. Implementation of the identified waste minimization opportunities was not part of the program. Percent waste reduction, net annual savings, implementation costs and payback periods were estimated.
