Abstract
Due to increasing environmental concerns and interest in sustainable materials, biomass is gaining
attention as an alternative to plastics. This study examines the formability of biomass powder com-
pacts using a forging process, with the goal of developing sustainable manufacturing techniques from
renewable resources. Biomass powders derived from Japanese cedar, bamboo, and hinoki were prepared
with particle sizes ranging from below 2.0 mm to 2.8 mm and combined with a natural binder composed
of sucrose and citric acid. The compacts were fabricated by molding wood powder at 120°C and then
forged at 180°C under a maximum load of 57kN. The research focuses on how biomass species and
particle size affect the compaction behavior, load-stroke response, and structural quality of the final
products. While the experimental process is ongoing, early trials suggest the particle sizes strongly
influence forming performance. Final results will contribute to the development of environmentally
friendly molded products from renewable resources.
