The objective of the project was to investigate the products of the pyrolysis of solid municipal wastes the optimum temperature at which the process should be carried out; the volume reduction of wastes when pyrolyzed, and the potential of any byproducts produced. Although the wastes used in the experimentation were 'typical San Diego refuse', the attempt was made to express the results in terms of such units that hopefully, these data would be useful to other communitites by adjustment in accordance with their own individual solid wastes classification. Experimental results were favorable in that waste volumes are significantly reduced and the process can be sustained by the incineration of its product(s) of the pyrolyzing equipment used has an over-all thermal efficiency of 60 percent or over.
