Patent ID: 8382863

Claim:
An engineered fuel feed stock having: a carbon content of between about 70 wt % and about 80 wt %, a hydrogen content of between about 4 wt % and about 9 wt %, an ash content of less than about 10 wt %, wherein the O/C ratio is between about 0.05 and about 0.12, 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 components of the plurality of MSW waste feeds 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.
