ABSTRACT:
The treatment of solid waste and sewage sludge with the recovery of natural resources comprising subjecting all or at least a portion of the sewage sludge to wet oxidation reaction to reduce the COD by an amount of at least 50% and preferably 50-85% and using the excess heat from the wet oxidation reaction to dry the solid waste and subjecting the combined solids from the wet oxidation reaction and the solid waste to pyrolysis under non-oxidizing conditions whereby the products from the pyrolysis reaction are readily separable into valuable constituents which are easily recovered.
