A system for making synthetic wood products from waste wood fiber and recycled plastic material by mixing waste wood fiber having a moisture content of less than about 15% with dry waste plastic material, including low density and/or high density polyethylene; heating and kneading the mixture to form a homogeneous mass; sizing the mass into discrete chunks suitable for use as an extruder feed material; extruding the material to form products having predetermined cross sections; and rolling and cooling the product to prevent deformation of the product shape.
