Abstract
A method of processing construction and demolition (C&D) debris at a location includes a set of processing steps. The method begins upon receipt of bulk C&D debris at the location. The bulk C&D debris is sorted into at least a first portion for further processing, and a second portion that is set aside. The first portion is then processed into a substantially homogenous wood waste material having particles of a given size by the unordered steps of shredding, screening, metals separation and flotation. The substantially homogenous wood waste material is then dried so that the particles have moisture content within a desired range. The wood waste material particles are then delivered into a molten metal bath at a submerged depth for gasification. Preferably, the process operates in a continuous or partially-continuous manner within a given facility, or within co-located facilities.
