SUSTAINABLE MANUFACTURING SYSTEM FOCUSING ON THE NATURAL GROWTH OF BAMBOO: LIFE CYCLE ASSESSMENT OF BINDER-FREE COMPOSITES MADE FROM BAMBOO FIBERS EXTRACTED WITH A MACHINING CENTER

摘要

Bamboo is a natural resource widely distributed in Southeast Asia, including Japan. It has drawn attention as a sustainable and environmentally safe material because it is renewable and has a quick growth rate. Bamboo fiber also has high specific strength and stiffness. A self-bonding fiberboard using high-quality bamboo fiber extracted with a machining center has been fabricated by hot press forming. Therefore, a sustainable manufacturing system that focuses on bamboo is proposed. This paper describes the environmental burdens of this system, which are evaluated quantitatively using life cycle assessment (LCA).
