OPERATION BREAKTHROUGH SITE WASTE MANAGEMENT SYSTEMS AND PNEUMATIC TRASH COLLECTION

摘要

The results of studies on trash - collection methods in 10 cities at 10 housing complexes (9 were HUD - built complexes) are presented. The study objectives were to evaluate the economics, effectiveness, and feasibility of using improved solid waste collection systems in new communities, to determine the most practical, convenient, quiet, sanitary, and economical waste collection systems, and to guide development of solid waste management systems for future projects. Data were gathered during site visits. The Jersey City, N.J., pneumatic trash collection system, the main focus of the study, required an extensive, detailed investigation. Specific tests and experiments were performed to determine overall system performance. Each of the collection systems was investigated in terms of quantity of solid waste collected per type and number of containers and number and type of dwelling units; distances traveled between services and total distance to collect onsite; time spent on various collection activities including productive collection time, handling and walking time, waiting time, and time spent on other activities; mechanical equipment performance; compactor load capacity; and storage container effectiveness, sanitation, and user satisfaction. The evaluations indicate that methods used at Macon, Ga., Memphis, Tenn., Sacramento, Calif., and King County, Wash., are the most effective and economical although the pneumatic trash collection system is too costly and unreliable to justify its advantages, i.e., less noise, less tenant awareness of trash equipment, and freed service vehicles for other operations. It is concluded that single - family attached and detached housing developments are best served by curbside, weekly refuse pickup; multifamily low - rise buildings are best accommodated by curbside pickup but with centrally located containers; and household compactors can only be recommended if weekly pickup is provided and residents are taught how to use compactors. Communal compactors are not recommended. Discussions and recommendations for each site are provided.
