End-of-pipe treatment must be replaced by innovative, in-process changes if industrial plants are to creatively meet the upcoming 1983 EPA pollution control requirements. By-product recovery, production, and utilization are alternatives needing research, development, and financial backing. This paper discusses (1)existing and potential systems for by-product recovery, (2)the concept of an industrial complex created totally for complete waste product utilization and by-product production, and (3)a practical approach to optimizing end-of-pipe treatment versus in-process changes. Examples of by-product utilization are protein recovery, solids recovery for cattle feed, and waste-product conversion to secondary products.
