  • Patent number: 10626340
    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.

  • Patent number: 10611974
    Abstract: 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.

  • Patent number: 10563144
    Abstract: Disclosed are novel engineered fuel feed stocks, feed stocks produced by the described processes, methods of making the fuel feed stocks, methods of producing energy from 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 and contain a sorbent. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels. In addition, one or more sorbents can be added to the feed stocks in order to reduce the amount of a variety of pollutants present in traditional fuel and feed stocks, including, but not limited, sulfur and chlorine. Further, these feed stocks with added sorbent can mitigate corrosion, improve fuel conversion, extend power generating plant lifetime, reduce ash slagging, and reduced operating temperature.

  • Publication number: 20190322956
    Abstract: The invention relates to the use of engineered fuel feedstocks to control the emission of sulfur-based, chlorine-based, nitrogen-based, or mercury-based pollutants, such as SO2, SO3, H2SO4, NO, NO2, HCl, and Hg that are generated during the combustion of fossil fuels, such as coal. Disclosed are novel engineered fuel feedstocks, feedstocks produced by the described processes, methods of making the fuel feedstocks, methods of producing energy from the fuel feedstocks, and methods of generating electricity from the fuel feedstocks.

  • Publication number: 20180327682
    Abstract: Systems and methods for processing and sorting a municipal solid waste stream are described herein. A system can include a processing sub-system configured to receive a municipal solid waste stream and to remove the non-processable waste, a processing apparatus configured and disposed to receive constituents of the municipal solid waste stream from the processing sub-system and reduce the size of the constituents of the waste stream to an average particle size of less than about ¾ inch, and separators configured to sort the waste stream into constituents based on density.
