| Abstract Application of thermal insulation for building and industrial sectors is a radical technique for minimizing energy losses and limit greenhouse gasses emissions GHG. The safety recycle of accumulated wastes and environmental burdens is another effective technique for GHG control. In this work we fabricated eco-friendly thermal insulation using agricultural and industrial wastes. The raw materials used are Corn Cob and Sugarcane bagasse; Chitosan as clean adhesive is used too. Many Processes are required for fabrication, beginning with washing, and drying. Then grinding and stiffing took place. Compression process with hydraulic piston converts crushed raw into disc samples with 6mm. thickness and 10 cm. diameters. To define best sample composition and optimum conditions; many samples are prepared, and many Standard Examinations have done. The best sample Composition is 14 gm. of (40% corn cobs & 60% Bagasse) and additives of (10 gm. Chitosan, 2gm. Synthetic polymer and thin layer of Aerogel painting).This sample got least thermal conductivity of 0.04 W/mk; it guarantees low surface temperature of 38ºC for insulated hot fluid pipes. Thermal performance of this composition is perfect represented in slow decomposition at high temperatures. Mechanical tests through (SEM and Contact angles Analysis) proved sample quality. These results clarified the possibility of converting the sample from laboratory scale to commercial production scope. This product can contribute for realizing zero energy losses for building and industrial sectors, which is the 21th century goal. | ||||
