摘要： Integrated methods and systems for recycling waste material including waste paper are provided, the methods including treating the 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.
