Abstract
Apparatus for processing waste-derived cellulose fibre into carbon char comprises an autoclave for treating waste with steam to produce processed material. The processed material includes cellulose fibre and plastics. The apparatus also includes a drying system for drying the cellulose fibre, and a torrefying unit for torrefying the dried cellulose fibre to produce carbon char. Thermal conversion means for thermally converting either said plastics or said VOCs provides heat for at least one of the autoclave, the drying system and the torrefying unit.

Apparatus for processing waste-derived cellulose fibre into carbon char, comprising:
- an autoclave for treating waste with steam to produce processed material, said processed material including cellulose fibre and plastics;
- a drying system for drying said cellulose fibre;
- a torrefying unit for torrefying said dried cellulose fibre to produce carbon char and VOCs;
- and
- thermal conversion means for thermally converting either said plastics or said VOCs, in order to provide heat for at least one of said autoclave, said drying system or said torrefying unit.
A method of producing carbon char from waste, comprising the step of processing waste by:
- treating said waste with high pressure steam to produce processed material that includes cellulose fibre and plastics, and
- torrefying said cellulose fibre to produce carbon char and VOCs;
- wherein heat used during said step of processing waste is produced by thermally converting at least one of said plastics and said VOCs.
