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.

Abstract: A method of making a composite material for dehydration of gases includes the steps of grinding date palm wood fibers to produce a fiber powder, immersing the fiber powder in an alkali solution, filtering fiber powder from the alkali solution to obtain treated fiber powder, drying the treated fiber powder, mixing the dried treated fiber powder with melted polylactic acid to form a composite material, extruding the composite material, and molding and pressing the extruded composite material. The resultant composite material may then be used to dehydrate gas by contacting the gas with the composite material such that water from the gas is adsorbed onto the surface of the composite material.

Abstract: The biodegradable composite insulation material is made from date palm leaf fibers and powdered okra. The date palm leaf fibers have a concentration of between 50 wt % and 90 wt % of the biodegradable composite insulation material, and the powdered okra has a concentration of between 10 wt % and 50 wt % of the biodegradable composite insulation material. The biodegradable composite insulation material is prepared by mixing date palm leaf fibers and powdered okra, in the above concentrations, to form a mixture. This mixture is then wetted with water, added to a mold, and heated under pressure to form a compressed article. The compressed article is then dried to form the biodegradable composite insulation material.

Abstract: A bioplastic blend is disclosed. The bioplastic blend may comprise a polylactic acid polymer and a lignocellulosic biomass. The lignocellulosic biomass may be a particulate and have an average particle size that is less than or equal to 60 micrometers, or less than or equal to 50 micrometers. The lignocellulosic biomass may be a particulate and comprise greater than or equal to 50 percent by weight of the bioplastic blend, or greater than or equal to 60 percent by weight of the bioplastic blend. In addition, the bioplastic blend may comprise a plasticizer.

Abstract: A thermal insulating material made from date palm surface fibers and a method of manufacturing the thermal insulating material using waste material from the date palm tree is provided. The thermal insulating material includes date palm surface fibers and polyvinyl alcohol. The method may include softening date palm surface fibers (DPSF), drying the DPSF, infusing the DPSF with polyvinyl alcohol (PVA), and casting the PVA infused DPSF to produce the thermal insulating material made from date palm surface fibers. The thermal insulating material has a low thermal conductivity, demonstrating its suitability to insulating structures.

Abstract: The biodegradable composite insulation material is a composite of wood from the date palm tree (Phoenix dactylifera) and polylactic acid. The composite may have up to 50 wt % date palm wood powder of maximum particle size of 212 ?m, the balance being polylactic acid (PLA). The composite may be prepared by melt blending the date palm wood powder with polylactic acid pellets in a twin screw extruder at 190° C., followed by compression molding the blend in a press or the like into the desired shape for building thermal insulation, and finally, annealing the molded product for three hours at 95° C. The composite material is biodegradable, thermally insulating, water-resistant and relatively strong.
