Abstract: Energy consumption and environmental protection are strongly connected. Thermal insulation is a poor conducting material. Thermal insulation' applications for building and industrial sectors minimise both energy losses and green gases emissions. The objective of this work is the fabrication of thermal insulations by recycling rice wastes (RRW). Fabrication stages are preparation and grinding, adding several binders with different compositions. Then samples are compressed into discs; to test their thermal efficiency, handling, and usability. The best sample composition is (60% grinded rice wastes) and (40% additives of recycled dissolved foam and polyvinyl acetate). Painting the sample with thin protective layer of aerogel or rosin or epoxy improves thermo-mechanical performance of it. Initial estimation of an industrial case study 'improvement due to apply (RRW) is saving of fuel cost by 1,700,000 $/y and decrease of carbon 'emissions by 95%. Energy management and wastes recycle technique; have economic benefits and good environmental impact.
