This study addresses the issue of waste generation within the food industry, focusing on the conversion of rice husk waste into value-added products. The investigation involves a comprehensive characterization of microcrystalline cellulose extracted from the rice husk and reinforcing them in bio-epoxy resin to determine its feasibility in producing ecofriendly products. The dried rice husk waste was made to undergo a series of treatments, including alkali, acid hydrolysis, and bleaching for extracting high purity microcrystalline cellulose. Physio-chemical, morphological, thermal, and spectroscopy analyses were performed on rice husk microcrystalline cellulose (RHMCC), revealing a high cellulose content (94.39 %), favourable crystallinity (77.8 %), low density (1.571 g/cm
