ABSTRACT
This chapter reviews four metal cleaning case studies at various manufacturing operations and presents the different approaches and technology assessments that were used to change these metal finishing operations. In each of the case studies, both pollution prevention and a positive financial solution were achieved. Each case was site- and time-specific, indicating that pollution prevention is a proactive and on-going optimization problem, similar to the actual manufacturing processes. The solutions included chemical substitution, process modification, process modernization, housekeeping improvements, and recycle improvements.
