Anaerobic digestion is a possible method for treating urban solid wastes. This pilot plant study was undertaken to ascertain the effect of plastic refuse on the anaerobic digestion process of municipal solid wastes. The air-blown polyethylene film present in the air classified light fraction of solid waste from Pompono Beach, Florida, U.S.A. was removed by visual separation. Control digesters operating on this substrate, produced more gas than test digesters to which the plastic scraps had been returned.
