Patent ID: 8906119

Claim:
An engineered fuel feed stock comprising a carbon content of between about 40 wt. % and about 50 wt. %, a hydrogen content of between about 4 wt. % and about 9 wt. %, an ash content of less than about 5 wt. %, and wherein the feed stock has an O/C ratio of between about 0.8 and about 1.0, and wherein the engineered fuel feed stock contains biodegradable waste and non-biodegradable waste and substantially no glass, metals, grit, and noncombustible waste; produced by a process comprising: a) receiving a plurality of MSW waste feeds at a material recovery facility; b) inventorying the components of the plurality of MSW waste feeds of step a) as they pass through a material recovery facility based on the chemical molecular characteristics of the components; c) comparing the chemical molecular characteristics of the components of the plurality of MSW waste feeds inventoried in step b) with the chemical molecular characteristics of the engineered fuel feed stock; d) optionally adding additional engineered fuel feed stock components which contain chemical molecular characteristics, whose sum together with the inventoried components of step b) equal the chemical molecular characteristics of the engineered fuel feed stock.
