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.

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% and about 85%,
- a hydrogen content of between about 3% and about 8%,
- an ash content of less than 10%,
- wherein the O/C ratio is between about 0.0 land about 0.4 and the H/C ratio is between about 0.02 and about 0.2;
- b) combining and mixing together the selected components of step a) to form a feed stock;
- c) comparing the resulting chemical molecular characteristics of the feed stock of step b) with the chemical molecular characteristics of step a);
- d) optionally adding other fuel components to the selected components of step b) if the chemical molecular characteristics of the MSW waste components selected in step b) do not equal the chemical molecular characteristics of step a).
A method of producing an engineered fuel feed stock, the method comprising:
- a) receiving a plurality of MSW waste streams;
- b) selecting for the engineered fuel feed stock chemical molecular characteristics comprising a carbon content of between about 40% and about 85%, a hydrogen content of between about 3% and about 8%, an ash content of less than 10%, and wherein the O/C ratio is between about 0.01 and about 0.4 and the H/C ratio is between about 0.02 and about 0.2;
- c) inventorying the components of the plurality of MSW waste streams based on the chemical molecular characteristics of the components;
- d) comparing the chemical molecular characteristics of the inventoried components of the plurality of MSW waste streams of step c) with the selected chemical molecular characteristics of step b);
- and
- e) optionally adding additional fuel components with the required chemical molecular characteristics to inventoried components of step c) to meet the desired chemical molecular characteristics of step b) for the engineered fuel feed stock.
