Patent ID: 8157874

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 components from a processed MSW waste stream which components in combination have chemical molecular characteristics 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 5 wt %, an O/C ratio of between about 0.8 and about 1.0; an H/C ratio of between about 0.1 and about 0.14; 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 an 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 feed stock of step b) do not fall within the chemical molecular characteristics of step a).
