The increasing demand for sustainable materials has driven extensive research on lignocellulosic biomass as an alternative to petroleum-based materials. This study aimed to develop a cellulose-based filter using biomass and assess its environmental impacts by life cycle assessment (LCA). Cellulose was extracted from bark sawdust, board wood chips, and pulpwood chips with yielding the highest extraction rate (78.7%). Electron beam irradiation (EBI) was applied as a pre-treatment, achieving a maximum cellulose yield of 82% at 100 kGy and effectively reducing the need for chemical reagents. The resulting filter exhibited enhanced tensile strength and folding endurance with higher cellulose content, while air permeability decreased. A cellulose-to-polypropylene ratio (70:30) was determined as optimal condition for the LCA study. The LCA results showed that the cellulose-based filter reduced greenhouse gas emissions by approximately 15.6% compared to PP-based filters, primarily due to lower emissions in the manufacturing phase. This study demonstrates the potential of cellulose-based filters as an eco-friendly alternative and highlights the role of EBI in optimizing extraction efficiency and reducing environmental impact. Further research is warranted to integrate EBI into LCA and evaluate scale-up industrial applications to manufacturing biomass based-filters.
