Process for making extruded panel product

A process for producing a continuous running length of construction wall paneling from waste thermoplastic material including one or more or all of thermoplastic bottles, toys, tires, cartons, containers and the like and cellulose fiber material such as shredded tree bark comprising the sequential repeated steps of:

• (1) Simultaneously evenly distributing, from respective continuous flow sources, a substantially continuous bottom layer of shredded thermoplastic material on a first section of three cascaded contiguous sections of a planar surfaced movable conveyor in a thermal environment sufficient to fuse said thermoplastic material, an intermediate layer of shredded cellulose material mixed with shredded thermoplastic material on the second section in a thermal environment sufficient to fuse the thermoplastic material distributed in that section, and a further substantially continuous top layer of said shredded thermoplastic material on the third section in a thermal environment sufficient to fuse the thermal plastic material;
• (2) advancing said conveyor forward by a predetermined distance while pressure rolling contiguous lengths of the material on said conveyor as it advances from the first to second section, the second section to the third, and from the end of said third section;
• (3) stopping said conveyor after completing said predetermined advance distance.
