摘要： Methods are provided for reuse of a sludge from a waste fiber supply including an organic fraction and an inorganic fraction. Generally, methods include converting the sludge by burning the sludge to remove a majority of the organic fraction and produce an ash with inorganic materials in an amount of at least about 80% by weight of the ash and adding the ash to a plastic pyrolysis system in an effective amount to remove at least a portion of one or more contaminants from a plastic feed stream of the plastic pyrolysis system. Integrated recycling systems also are provided and include a fiber recovery system; a means for at least partially dewatering a sludge; a burner; and a pyrolyzer.

摘要： Methods and systems are provided for improved liquefaction of a lignocellulosic biomass. The methods include reacting a lignocellulosic biomass slurry at mild conditions for a short period to produce a first reaction mixture having a reduced viscosity as compared to the lignocellulosic biomass slurry and that is substantially free of levulinic acid and hydroxymethylfurfural. The methods further include separating the first reaction mixture into a solid fraction and a liquid fraction, the solid fraction having a majority of lignin from the lignocellulosic biomass slurry and the liquid fraction having a majority of hemicellulose and greater than about 30% by weight of cellulose from the lignocellulosic biomass slurry. The method advantageously prevents or eliminates the formation of tar and/or char.
