The quantity of sewage sludge and solid waste that the minicipalities of the United States must dispose of is increasing while the conventional disposal methods are being restricted or eliminated. A number of Federal laws, enacted over the past few years have directed waste disposal toward the use of new and innovative technologies that incorporate resource recovery and energy recovery systems. One alternative for the disposal of solid waste and sludge is combined disposal, or codisposal. This paper is intended as an introduction to codisposal technology for municipalities considering this option. The two basic thermal codisposal techniques are described and seven codisposal processes are discussed. Options available for financing municipal codisposal plants are outlined and potential environmental impacts of these plants are noted. Applications of codisposal technology in the United States and in Europe are described.
