Study on agricultural waste utilization in sustainable particleboard production

The construction industry plays a crucial role in the global economy, but its heavy reliance on forest resources has led to significant environmental concerns, such as deforestation and climate change. The growing demand for sustainable and affordable building materials has driven researchers to explore the potential of agro-industrial wastes as alternative raw materials for particleboard (PB) production. This study aims to contribute to the growing body of knowledge on sustainability in the built environment by examining the trends, key factors, and environmental implications of utilizing agro waste in particleboard manufacturing through a comprehensive review of recent research. Utilizing the PRISMA approach, this study selects and systematically reviews 50 journal articles and conference papers from Scopus database, published between 2000 and 2024. Research findings reveals a diverse range of agro waste such as sugarcane bagasse, rice husks, corn stover, peanut shells, wheat straws and coconut fibers etc, been successfully used as raw materials for particleboards manufacturing. The bibliometric analysis highlights present focus on production processes, adhesive systems, particle properties, and material optimization. Also, the performance of agro based particleboards is influenced by the type and proportion of agro waste, particle size and geometry, adhesive type and content, and processing conditions. While the use of synthetic resins currently dominates the research landscape as binders, there is growing appetite for bio-based and natural adhesives. However, challenges such as seasonal availability and the need for additional processing must be addressed for large-scale adoption. The study concludes with recommendations for collaborative research, eco-friendly adhesive development, and supportive policies to promote the use of agro waste particleboards in sustainable construction.
