Abstract
In a process for transforming waste material into useful material, a quantity of waste material such as household garbage or municipal solid waste is provided. The waste material is pre-shredded into pre-shredded waste material. The pre-shredded waste material is processed to at least partially remove one or more selected material components, thereby providing a processed pre-shredded waste material. The processed pre-shredded waste material is then secondarily shredded into secondarily shredded waste material which is then hydrolyzed under pressure greater than ambient pressure to create an aggregate cellulose pulp.

A process for transforming waste material into useful material, the process comprising steps of:
- (a) providing a quantity of waste material;
- (b) pre-shredding the waste material into pre-shredded waste material having a nominal maximum piece size of at least about 6 inches;
- (c) processing the pre-shredded waste material to at least partially remove one or more selected material components, thereby providing a processed pre-shredded waste material;
- (d) secondarily shredding the processed pre-shredded waste material into a secondarily shredded waste material having a nominal maximum piece size no greater than about 2 inches;
- and
- (e) hydrolyzing the secondarily shredded waste material under pressure greater than ambient pressure to create an aggregate cellulose pulp.
