Abstract: Waste processing system, for performing a waste processing process, the system including a shredder, a grinder and a steam explosion device such as a cooking extruder. The waste processing system is used to process raw waste, such as consumer waste, into an end product such as pellets. The waste processing includes an acid treatment step to sanitize, purify and/or increase a cellulose content of the waste. The acid is preferably a weak acid and/or an organic acid.

Abstract: Waste processing system including a shredder, a grinder and a steam explosion device such as a cooking extruder. The waste processing system is used to process raw waste, such as consumer waste, into an end product such as pellets. One potential use for these pellets is pyrolization to form biogas. Because of the uniformity composition of the processing waste (see DEFINITIONS section), imparted by the shredder and grinder, and because of the uniformity of distribution of plastic in the processing waster, imparted by the steam explosion processing, the end-product made by systems according to the present invention are superior with respect to several physical characteristics and especially well suited for pyrolization to make biogas.
