A 24-month study of solid waste and scrap generation, and related plant management practices, in the automotive industry was performed. The industry was categorized and defined in accordance with the United States Standard Industrial Classification (SIC) Codes 3711, 3712, 3713, and 3714. Special and custom vehicle and body manufacturers in SIC 3711, 3712, and 3713; and the parts and accessories suppliers in SIC 3714 were surveyed. The results of an in-house survey of Automobile Manufacturers Association (AMA) member plants covering all four SIC Codes is included in this report. The information presented was derived from five principle sources: (1) industry-related publications and general references; (2) automotive industry trade associations; (3) questionnaires received from 43 different manufacturing plants within the four SIC Codes; (4) questionnaires from cities within 48 Standard Metropolitan Statistical Areas (SMSA) with automotive industry plants; and (5) field interviews and studies completed at a representative cross section of 74 manufacturing assembly plants. The questionnaires were developed in cooperation with industry, the Bureau of Solid Waste Management, and other authorities. A general description is given of the industry plant locations, minimum estimated plant values, vehicle production, employment, industry employee productivity, products, and manufacturing processes. Waste and scrap generation sources are identified; handling, collection, and disposal methods and their costs are presented; and the effects of automotive industry plant wastes on the environment and community are discussed. Stepwise multiple regression was applied to the investigation of plant parameters for predicting waste and scrap generation.
