A waste processing system includes a pyrolysis apparatus that pyrolyzes a combustible waste, a melt-and-mold apparatus that generates an ingot of resin and combustible gas from a synthetic-resin waste, and an oil extraction apparatus that generates combustible oil and combustible gas from the ingot of resin. The melt-and-mold apparatus has a melter that melts the synthetic-resin waste using heat produced by the pyrolysis apparatus, the oil extraction apparatus has a pyrolyzer that pyrolyzes the ingot of resin using the heat produced by the pyrolysis apparatus, and at least one of the combustible gas generated at the melt-and-mold apparatus and the combustible gas generated at the oil extraction apparatus is supplied to the pyrolysis apparatus.

Energy is generated from cellulosic biofuel waste streams, specifically a lignin filter cake and a waste syrup, by combusting these waste products in a fluidized bed combustor under specified conditions. The heat and steam generated can be used to generate electricity and/or in cellulosic biofuel production processes.

An apparatus is disclosed for the pre-capture of carbon from natural gas and/or other light gaseous hydrocarbons and oils, and for co-firing the resulting hydrogen and any remaining hydrocarbons with higher carbon ratio fuels, such as coal and heavy oils and even lower carbon ratio natural gas, in a steam electric generator and/or other boilers, processes, reactors, power plants, engines and combustion turbines, and combined cycle units, to reduce their carbon dioxide production and emissions to the environment, and for co-processing the syngas with other feed materials to react them in a separate vessel and produce a desired outcome.
