Abstract

CELRe is a cellulose fiber-reinforced resin that utilizes environmentally friendly, high-strength, plant-derived cellulose fibers. These cellulose fibers are highly dispersed within the resin through advanced kneading technology using a twin-screw extruder. CELRe can be injection molded in the same way as conventional thermoplastic resins, and by adjusting the molding conditions, it exhibits an excellent fluidity and a moldability. Additionally, appropriate moisture content control and drying treatments enable the production of highquality molded products. Furthermore, it is highly recyclable and has little deterioration in its physical properties, making it easy to reuse. This will promote the reduction of CO2 emissions and the effective use of resources, contributing to the realization of a sustainable society. In the future, CELRe is expected to be applied to many industries as an important material in today’s world, where environmental consideration and technological innovation are required.
