The objective of this paper is to present information on pollution prevention practices and economics to recommend it as a significant part of industrial waste management. The waste reduction/waste minimization/pollution prevention sequence is described and optimized. Experiences in pollution prevention for three separate industries are presented. The pollution prevention approach is stressed for its positive effects on cost, expenses, environmental benefits, as well as other less tangible benefits. The conclusion is that you can generally reduce, minimize or eliminate waste and make money doing it. This is especially the case with old processes having significant residuals.
