Integrated methods and systems for recycling waste material including waste paper are provided, the methods including shredded the waste material, treating the shredded waste material in the pressure vessel at an elevated processing temperature and an elevated processing pressure to form a treated waste material including a substantially re-pulped waste paper; discharging the treated waste material from the pressure vessel; and thereafter separating and diluting the treated waste material to dilute a portion including the substantially re-pulped waste paper to from about 1% to about 20% by weight solids. The recovered paper pulp fraction and substantially fiber-free recoverable/recyclable plastics and metals may be further separated and used as feedstock in a variety of subsequent processes.

A method to facilitate recycling waste material, including waste paper and organic material, comprises the steps of receiving a plurality of plastic-wrapped compressed bales of the waste material at a waste material recycling location from a remote baling location, thereafter introducing the plurality of plastic-wrapped compressed bales into a re-pulping device at the waste material recycling location to form a treated waste material including substantially re-pulped waste paper, and thereafter discharging the treated waste material from the re-pulping device.
A method for recycling waste material including waste paper comprises the steps of introducing the waste material into a pressure vessel, re-pulping the waste paper in the pressure vessel at an elevated processing temperature and pressure to form a treated waste material including substantially re-pulped waste paper, thereafter introducing cooling water into the pressure vessel so as to cool the treated waste material in the pressure vessel to a discharge temperature below the elevated processing temperature and reduce odor emitted by the treated waste material, and thereafter discharging the treated waste material from the pressure vessel. The recovered paper pulp fraction is suitable as a feedstock in the manufacture of a variety of paper products including paper tissue and paper towel products.
