An increasing need for new information and ideas on the collection and disposal of solid wastes resulted in the National Conference on Solid Waste Research: researchers, educators, government officials, equipment manufacturers, and operating personnel brought together to discuss problems and interests in solid wastes. Conference objectives were to stimulate research and young researchers, point out resources for support of research, delineate problems, and project future needs for long-range problems. Conference proceedings present the latest ideas on research in the area of solid waste.
