摘要

On-site field disposal of paddy straw through burning poses a serious environmental challenge due to the release of particulate matter and greenhouse gases into the atmosphere. To address both pollution control and agricultural residue management, this study investigates the conversion of rice straw into sustainable composite boards for construction applications. The developed boards are proposed as insulating cores for sandwich panels, offering a bio-based alternative to conventional expanded polystyrene (EPS). Various chemical pre-treatment methods have been employed to modify the raw straw surface and improve interfacial bonding and overall material performance. The fabricated boards are characterized for their physical, mechanical, thermal, durability, and biodegradation behaviour to evaluate their feasibility for structural and non-structural uses. Experimental results indicate that the straw-based panels exhibit satisfactory performance, demonstrating their potential for integration into environmentally responsible building systems. Utilizing this abundantly available agricultural residue not only mitigates open burning practices but also promotes resource efficiency, rural value addition, and sustainable construction.
