ABSTRACT:
A process for preparing a composite product from an intake material incorporating commercial, municipal or industrial waste containing organic, plastic and fibrous material includes first granulating and sizing the material. The material is then heated in three consecutive phases, first at a temperature sufficient to achieve an internal temperature within the material of about 215.degree. to 250.degree. F., then at a temperature sufficient to achieve an internal temperature within the material of about 250.degree. to 320.degree. F. and then at a temperature sufficient to achieve an internal temperature within the material of about 320.degree. to 400.degree. F., wherein said material is continuously mixed during said heat phases. The material may then be co-extruded with a reinforcement structure and forced into vacuum profile dies to form a product or compression molded to form a product and cooled.
