Patent ID: 8157875

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 70 wt % and about 80 wt %, a hydrogen content of between about 4 wt % and about 9 wt %, an ash content of less than 10 wt %, an O/C ratio of between about 0.05 and about 0.12, an H/C ratio of between about 0.03 and about 0.07, 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 s 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).
