Abstract
Systems and methods for producing engineered fuels from solid waste material are described herein. In some embodiments, a method includes receiving a waste stream at a multi-material processing platform and separating the waste stream to remove non-processable waste and marketable recyclables. The method further includes conveying processable materials to a material classification system and incorporating additives to produce an engineered fuel from the constituents of the waste stream.

A method of forming an engineered fuel feed stock from a solid waste stream, the method comprising:
- removing non-processable waste from the solid waste stream;
- shredding the solid waste stream to reduce the size of constituents of the solid waste stream to be less than a predetermined size to form a shredded solid waste stream;
- removing additional non-combustible waste from the shredded solid waste stream to form a processable waste stream;
- screening the processable waste stream to remove an undersized portion of the processable waste stream;
- separating the processable waste stream into at least a plastic stream and a fiber stream;
- and
- combining a quantity of the plastic stream and a quantity of the fiber stream to form the engineered fuel feed stock.
A method of forming an engineered fuel feed stock from a solid waste stream, the method comprising:
- removing non-processable waste from the solid waste stream;
- shredding the solid waste stream to reduce the size of constituents of the solid waste stream to be less than a predetermined size to form a shredded solid waste stream;
- removing ferrous metal from the shredded solid waste stream;
- removing non-ferrous metal from the shredded solid waste stream;
- removing food waste from the shredded solid waste stream;
- separating the processable waste stream into at least a plastic stream and a fiber stream;
- and
- combining a quantity of the plastic stream and a quantity of the fiber stream to form the engineered fuel feed stock.
A method of forming an engineered fuel feed stock from a municipal solid waste stream, the method comprising:
- receiving the municipal solid waste stream on a tipping floor;
- removing non-processable waste from the solid waste stream;
- shredding the solid waste stream to reduce the size of constituents of the solid waste stream to be less than about 12 inches to form a shredded solid waste stream;
- removing ferrous metal from the shredded municipal solid waste stream;
- removing non-ferrous metal from the shredded municipal solid waste stream;
- screening the shredded municipal solid waste stream to remove food waste;
- separating the solid waste stream with an air separator into at least a plastic stream and a fiber stream;
- combining a quantity of the plastic stream and a quantity of the fiber stream to form the engineered fuel feed stock.
