Patent ID: 8192513

Claim:
A method of producing an engineered fuel feed stock from a processed MSW waste stream, the method comprising the steps of: a) selecting a plurality of components from a processed MSW waste stream which components in combination have chemical molecular characteristics comprising a carbon content of between about 30 wt % and about 80 wt %, a hydrogen content of between about 3 wt % and about 10 wt %, an ash content of less than 10 wt %, an O/C ratio of between about 0.8 and about 1.0, an H/C ratio of between about 0.07 and about 0.16, and wherein the engineered fuel feed stock contains biodegradable waste and non-biodegradable waste and substantially no glass, metals, grit, and noncombustibles; b) combining the selected components of step a) to form the engineered fuel feed stock; c) comparing the resulting chemical molecular characteristics of the engineered fuel feed stock of step b) with the chemical molecular characteristics of step a); d) optionally adding other fuel components to the engineered fuel feed stock of step b) if the chemical molecular characteristics of the MSW waste components selected in step b) do not fall within the chemical molecular characteristics of step a).
