Improved methods for the treatment of commingled wastes and process systems for practicing those methods are provided. The methods are practiced by first treating the commingled waste material in a primary treatment unit in the presence of a carrier fluid to separate the organic waste from the inorganic waste. The carrier fluid and the gaseous products from the primary unit are then treated in a flameless oxidizer, which efficiently destroys any remaining organic compounds. In one embodiment, the process gases exiting the flameless oxidizer are recycled to the primary treatment unit.

[ What is claimed is:] [1.] A method for treating commingled waste, comprising the steps of:(a) feeding a commingled waste stream into a primary treatment unit, said commingled waste comprising organic material and inorganic material;(b) separating a portion of the organic material from the inorganic material in said primary treatment unit and decomposing a portion of the organic material into decomposition products comprising CO, CO.sub.2, H.sub.2, and H.sub.2 O in said primary treatment unit to form an organic gas stream comprising at least CO or volatile organic compounds, wherein the portion of the organic material decomposed in said primary treatment unit is less than 75% by volume of the organic material;(c) removing said organic gas stream from said primary treatment unit;(d) feeding said organic gas stream at a temperature of at least 400.degree. F. into a first portion of a matrix bed of heat resistant material contained within a flameless oxidizer;(e) injecting supplemental air, oxygen, fuel, or combinations thereof into said first portion of said matrix bed to react with said organic gas stream;(f) heating said organic gas stream to a temperature of at least 1400.degree. F. in said matrix bed and oxidizing the volatile organic compounds or CO into gaseous products in an oxidation wave within said matrix bed.
