Abstract: A hog fuel board is made by placing a hog fuel mat including an ammonium chloride catalyst with flexible non-sticking layers on outside surfaces between screens in a preheated platen press and pressing the mat to preset stops and for a predetermined time and pressure to cause adhesives naturally present in the hog fuel to disperse throughout the board. The presence of ammonium chloride as a catalyst uniformly distributed through the hog fuel mat significantly lowers the temperature required at the heating press platens to form a board which also has improved properties. There is also described a hog fuel veneer board with a hog fuel mat sandwiched between veneer sheets and a lumber product with a hog fuel coating thereon. These additional products are both formed using the ammonium chloride catalyst to reduce press temperatures and create a product with improved properties, particularly, internal bond strength.

Abstract: A hog fuel board is made by placing a hog fuel matrix with flexible non-sticking layers on outside surfaces between screens in a preheated platen press and pressing the matrix to preset stops and for a predetermined time and pressure to cause adhesives naturally present in the hog fuel to disperse throughout the board. The process requires heating platens higher than used for particle board but avoids using a vacuum press. There is also supplied a hog fuel veneer board with a hog fuel matrix sandwiched between veneer sheets and a lumber product with a hog fuel coating thereon.
