The concept originally to be evaluated entailed mixing the organic residual from a solid waste, materials recovery system with municipal wastewater sludge and then processing this mixture via anaerobic digestion to produce a methane rich fuel gas. The undigested material was dewatered for evaluation as a solid fuel. The process was not fully successful, due in part to inadequate mixing in the 378,000-liter test vessel. The study scope was therefore increased to include an evaluation of 'state of the art' mixing methods as applied to solid waste digesters. The results of that mixing study are presented. Two specially selected mixing systems were tested and evaluated to determine how effectively they could prevent the formation of fibrous mats and stringers.
