Special Centennial Symp "Technology for the Future to Control Industrial & Urban Waste" :3 pages
Very large quantities of discarded plastic articles are entering the municipal waste disposal facilities, posing new problems in waste processing and accounting for a substantial and growing loss of resources. Methods for utilizing these waste plastics are being sought at the research center of the Bureau of Mines in Rolla, Missouri. A sample of such waste obtained through a community-wide collection program, was analyzed and tested; the results are presented in this article. The fabrication of useful secondary products is discussed as a possible outlet for waste thermoplastics, polyethylene and polypropylene, and the possibility of using waste halide polymers, in particular polyvinyl chloride, as chemical raw material is considered. A flow diagram for a sink-float separation process for waste plastics is presented.
