Abstract
A process for making composite products from waste material comprises the steps of a) obtaining fibrous material produced by the thermal treatment of waste materials with pressurized steam; b) mixing the fibrous material with a binding material; c) forming the resulting mixture into a shape; d) pressing the shaped mixture under pressure; and e) hardening the mixture; wherein the process also comprises the steps of the separating out the fibrous material and deodorizing the fibrous material. The waste material may be domestic bin liner waste.
