A municipal solid waste recycling facility for producing a solid recovered fuel is provided. The municipal solid waste recycling facility includes a pre-shredding unit and a shredding unit. The pre-shredding unit includes a trommel configured to sort a first stream of solid waste by size into a second stream of solid waste and a third stream of solid waste. The shredding unit includes a primary shredder configured to shred the second stream of solid waste.

This alternative fuel is a reclaimed waste product which has a solid, particulate consistency at ambient temperature. The fuel comprises a composite of petroleum pitch and a powder coating. The powder coating penetrates into the surface of the pitch. The powder coating is recycled ash, pulverized coal, or pulverized petroleum coke.

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 and system reprocess soiled animal bedding material commingled with animal manure. In one aspect the soiled animal bedding material is separated in a shaker to send at least a preponderance the manure to a holding tank. In another aspect the bedding is cleaned, rinsed and color is restored. The bedding material is subsequently dried and a bedding product, fertilizer product, and/or compacted product is formed. Alternatively, the bedding material is dried (without a compacting step) to form a product. In another aspect, the steps of separation, cleaning, rinsing and/or color restoration may be omitted.

Disclosed are novel engineered fuel feed storks, 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.
