The purposes of the project were related to the need to investigate the technical and economical feasibility of windrow composting as a method of managing municipal refuse. The feasibility of composting sewage sludge with the ground refuse was investigated. Equipment was evaluated and costs of various parts of the process were determined. Potential health problems associated with composting municipal refuse with sewage sludge were considered extremely important, therefore, the survival during composting of pathogenic organisms in the refuse or sewage sludge was determined. In addition, the benefits available from using the compost in various applications were evaluated. An assessment was made of the economical benefits from using compost for agricultural, horticultural, or soil amendment purposes. A determination was also made as to the maximum amount of refuse compost that the soil might accept without adverse effects. Results of investigations conducted and operational experiences from the project during the period June 1967 to September 1969 are reported.
