Abstract
Disclosed are novel engineered fuel feed stocks, feed stocks produced by the described processes, and methods of making the fuel feed stocks. Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels.
Claims23
An engineered fuel feed stock, comprising at least one component derived from a processed waste stream, the engineered fuel feed stock comprising:
- a carbon content of between about 60 wt. % and about 70 wt. %;
- a hydrogen content of between about 3 wt. % and about 10 wt. %;
- a moisture content of less than about 30 wt. %;
- an ash content of less than about 10 wt. %;
- and
- wherein the engineered fuel feed stock contains substantially no glass, metals, grit, and noncombustibles.
An engineered fuel feed stock, comprising at least one component derived from a processed MSW waste stream, the engineered fuel feed stock comprising:
- an H/C ratio of between about 0.025 (w/w) and about 0.20 (w/w);
- an O/C from about 0.15 (w/w) to about 0.3 (w/w);
- a moisture content of less than about 30 wt. %;
- an ash content of less than about 10 wt. %;
- and
- wherein the MSW waste stream contains biodegradable and non-biodegradable waste and the engineered fuel feed stock contains substantially no glass, metals, grit, and noncombustible waste.
An engineered fuel feed stock, comprising at least one component derived from a processed MSW waste stream, the engineered fuel feed stock comprising:

- an H/C ratio of between about 0.07 (w/w) and about 0.16 (w/w);
- an O/C ratio from about 0.15 (w/w) to about 0.3 (w/w);
- a moisture content of less than about 30 wt. %;
- an ash content of less than about 10 wt. %;
- and
- wherein the MSW waste stream contains biodegradable and non-biodegradable waste and the engineered fuel feed stock contains substantially no glass, metals, grit, and noncombustible waste.
