Wastes generated were characterized and quantified in typical hog slaughtering operations both before and after modifications were made to reduce wastewater volume and strength and to increase by-product recovery. The research was carried out in the Oscar Mayer plants at Madison, Wisconsin, Beardstown, Illinois, and Davenport, Iowa. Process modifications reduced the flow by 41%, the BOD5 by 63%, and the suspended solids by 63%. Most process modifications cost only a few hundred dollars; the most expensive change cost $12,000. Every modification will pay for itself within 1 or 2 years. Often the savings in water alone justifies a modification, and savings in waste treatment and surcharges are a bonus. Individual process modifications annually saved from $280 for simply turning off a valve up to $129,000 for modifying the hasher washer to recover more scrap for rendering.
