A Short Review on the Growth of Lightweight Agronomic Surplus Biomass Composites for Ecological Applications Using Biopolymers

Abstract

The escalating need to discover innovative approaches for creating sustainable materials, driven by the depletion of Earth's resources and heightened environmental concerns, has spurred numerous studies focusing on agricultural waste management. The significant annual generation of agricultural waste, amounting to approximately 1.3 billion metric tons globally, presents both ecological and financial challenges. This study emphasizes repurposing 60% of this annual agricultural waste, aligning with sustainable economy principles, and investigates the utilization of crop residues (450 million metric tons), straw (200 million metric tons), and other agricultural by-products (150 million metric tons) as supplementary ingredients for high-value goods. The methodology assesses the efficiency of employing 35% of this waste for lightweight biopolymer-based composites, targeting a 45% reduction in the environmental impact associated with conventional waste disposal. Results demonstrate a substantial 40% decrease in traditional waste disposal methods, with a 30% economic benefit realized through the conversion of 35% of agricultural waste into eco-friendly materials. This brief review explores the expanding field of lightweight agronomic surplus biomass materials, with a specific focus on the innovative utilization of biopolymers in creating environmentally friendly composites. It examines the sustainable repurposing and transformation of agricultural waste biomass, highlighting progress in the development of hybrids and emphasizing the myriad ways in which biopolymer-based materials contribute to environmental sustainability.
