Shop grade Thermal-fused melamine

Hello, I have large volumes of Melamine Product that i am looking for ideas or suggestions on what this product could be used for. I havve some ideas but would welcome any ideas that you might have. It is mainly Particle Board core, but I also have MDF and Luan core. All material has Thermal-fused Melamine laminate on one or both faces. The veneer laminate is sometimes a plastic Formica type coating, a paper coating, or wood veneer. Product is B grade due to wrinkles, scratches, or other minor defect in melamine face only, Board it’s self is 100% usable where appearance is not a factor, due to the minor imperfections. I have truckloads of this product in various sizes… 4ftx8ft, 4×9, 4×10,5×6, 5×9, 5×10, and thicknesses in 1/4”, 3/8”, 1/2”, 5/8”, 9/16”, 3/4” 7/8”, 1”, and 1 1/8” in most all cases this product is available at a lower cost than plywood or OSB. Thank you!
