Lignocellulosic Characterisation of Thatch Grass Sourced from Southeastern States of Nigeria for Particleboard Manufacturing

Abstract

The shift from thatch grass, a traditional roofing material, to modern materials in Nigeria has led to the underutilisation of the plentiful thatch grass species, raising concerns about environmental risks like bushfires. This study explores an innovative solution by repurposing species of thatch grass as an eco-friendly material for particleboard Manufacturing, which supports United Nations Sustainable Development Goals. The research includes an in-depth lignocellulosic analysis, examining components such as lignin, cellulose, hemicellulose, extractive content, and pH. Advanced techniques, including TAPPI methods, were employed for accurate determination. The lignin content for thatch grass samples ranged from a minimum of 20.998% to a maximum of 26.591%. Cellulose content exhibited variations, ranging from 40.873% to 45.086%. Hemicellulose content displayed variability, ranging from 20.556% to 27.349%. Extractive values fell within the range of 4.624% to 6.083%. The pH values for all samples remained within the range of 6.52 to 7.00. The results indicate that thatch grass species exhibit favourable lignin, cellulose, and hemicellulose contents within ranges suitable for particleboard Manufacturing. Extractive values and pH levels are consistent and meet industry standards. The results highlight the emerging possibilities of thatch grass species as a sustainable and environmentally friendly material for particleboard manufacturing in Nigeria, fostering eco-conscious practices and promoting a circular economy approach.
