Abstract
En 中文
In the current scenario, paddy straw burning or parali burning is a major environmental concern causing severe air pollution, and contributing to global warming as well as affecting human health. This study explores the gainful utilization of these agro-wastes paddy straw particulates (PSP) as reinforcement in polypropylene (PP) matrix for fabricating wood plastic composites (WPCs) with different filler loadings up to 60 wt% and manufactured via injection molding at 160℃. The developed composites were characterized for mechanical, structural, thermal and morphological properties. The density and water absorption of the developed WPCs ranged from 0.936 to 1.035 g/cm3 and 0.092–1.816%, respectively. Thermal conductivity decreased with increasing PSP content, reaching a minimum of 0.236 ± 0.012 W/mK at maximum 60 wt% filler. Further, maximum tensile and flexural strengths of 27.83 ± 0.49 MPa and 44.44 ± 0.13 MPa were achieved at 20% filler loading, whereas, maximum impact strength of 1.89 ± 0.13 KJ/m2 was recorded at 60 wt%. Thus, the findings confirmed the possibility of cellulosic PSP as a potential reinforcing filler for fabricating WPCs, significantly contributing towards sustainable circular economy approach aligned with United Nation Sustainable Development Goals (UNSDGs). Agro-wastes paddy straw as potential reinforcement in wood plastic composites (WPCs). Effective compatibilization between paddy straw particulates and polymer matrix for WPCs. Paddy straw valorization for value-added product and environmentally sustainable alternative. Contribution towards a sustainable approach and UN Sustainable Development Goals (UNSDGs). Developed WPCs exhibit good mechanical and thermal insulating property.
