- Waste stream segregation 0 Recovery for reuse or exchange The following summaries illustrate the application of these methods, based on a study of several companies (Schecter, April 1985) . Changg in Production jj&tgrj_aj_j: A manufacturer of radial saws re- placed its organic solvent spray paint system with a water-based anodic electrostatic immersion paint system. The company estimated that this system reduced volatile organic compound emissions from 3,040 lbs/day to only 160 lbs/day. The firm saves $600,000 per year in raw material costs because the system recovers and reuses 99.5 per- cent of the waste paint. The pay-back period was about 0.29 years based on reduced raw material costs and reduced disposal costs. Process Modifications: An electroplater of plumbing fixtures devel - oped a number of production process modifications to reduce wastes and improve production efficiency. New plating machine designs reduced drag out, minimized rinse water flows, and enabled chrome recovery. Degreaser modifications resulted in decreasing solvent usage almost 80 percent. Installing a drag-out recovery system and redesigning plating racks also saves the company over $4,200 a year in chemicals and reduced disposal costs. Waste Stream Segregation: A pesticide manufacturer modified its dust collection system to segregate and recover hazardous wastes. By collecting the pesticide waste dust produced in each production area separately, rather than in a single baghouse for all sources, the firm was able to recover collected material for product processing. The system had a payback period of 10 months, and currently saves the company $11,000 per year on waste disposal costs and reduced raw material costs. Recovery for Reuse or Exchange: A steel smelting company developed a system to reduce the cost of disposing of the waste collected by the PJ 9 9390502D.00D 10-3 Rev. 1 11/08/88
