Abstract: The buffing dust waste/polystyrene thermal insulator is a polymer composite containing 0.1%-25% by weight buffing dust waste from a leather tannery, the balance being polystyrene. The composite has extremely low thermal conductivity (e.g., 0.0447 W/m-K for a composite 10% budding dust by weight), making it a good insulator, while still having relatively high mechanical properties. The thermal insulator is made by mixing the buffing dust with the polystyrene polymer in a twin-screw extruder and pouring the mixture into a steel mold. The mold is heated and compressed in a hot press machine, e.g., at 500 kg force at 180° C. for 20 minutes, which may be followed by 500 kg force at 125° C. for an additional 20 minutes. The resulting composite polymer is suitable for use as thermal insulation in buildings.
