Abstract
Systems and methods for producing engineered fuels from municipal solid waste material are described herein. In some embodiments, a method includes combining a first waste stream that includes at least one of hard plastic, soft plastic and mixed plastic with a sorbent and increasing the temperature of the combined first waste stream and sorbent to a temperature of at least about 200° C. The method further includes combining the thermally treated first waste stream and sorbent with a second waste stream that includes fiber, and compressing the combined first waste stream, sorbent, and second waste stream to form a densified engineered fuel feedstock.

A method of producing an engineered fuel feedstock from a processed MSW waste stream, the method comprising:
- combining a first waste stream that includes at least one of hard plastic, soft plastic and mixed plastic with a sorbent;
- increasing the temperature of the combined first waste stream and sorbent to a temperature in a range of about 200° C. to about 400° C.;
- combining the thermally treated first waste stream and sorbent with a second waste stream, the second waste stream including fiber;
- and
- compressing the combined first waste stream, sorbent, and second waste stream to form a densified engineered fuel feedstock.
A method of producing an engineered fuel feedstock from processed MSW waste streams, the method comprising:
- heating a first classified waste stream including plastics to a temperature that is above a decomposition point and below an ignition point of the plastics to produce a second waste stream and a gas;
- extracting the gas from the second waste stream;
- reacting the gas to a less reactive state;
- combining the second waste stream with a third waste stream in a predetermined ratio to form an engineered fuel feedstock.
