Abstract
A method may include forming a mat including paper fragments, plastic fragments, and top and bottom outer surface layers, wherein the outer surface layers have maximum processing temperature values and consolidating the formed mat in a continuous hot press including three pairs of opposing top and bottom heating platens. A first pair of heating platens has a first heating power. A second pair of heating platens has a second, lower heating power. A third pair of heating platens has a third, even lower heating power. The method may include consolidating the formed mat in a continuous cold press including three pairs of opposing top and bottom heating platens. A first pair of cooling platens has a first cooling power. A second pair of cooling platens has a second, lower cooling power. A third pair of cooling platens and has a third, even lower cooling power.
