Mazda Motor and Hiroshima University Developing New Bioplastic for Vehicles from Cellulosic Biomass

Mazda Motor Corp. and Hiroshima University are collaborating on research to develop a new bioplastic from cellulosic biomass, which they are targeting for use in vehicles by 2013.

The Mazda Bioplastic Project will focus on designing a production process for an extremely versatile polypropylene, appropriate for extensive use in vehicles, by first converting non-food cellulosic biomass to ethanol, and then investigating various mixtures of ethylene and propylene.

The polypropylene must have sufficient heat resistance, strength and durability to be used in vehicle bumpers and instrument panels. The project will also seek to optimize the manufacturing process for the bioplastic so that it is eco-friendly and cost-effective.

Mazda’s previous research on biomass technology resulted in the world’s first high heat-resistant, high-strength bioplastic and the world’s first 100 percent plant-derived fabric for use in car seats. These two biomaterials are used in the interior of the Mazda Premacy Hydrogen RE Hybrid. Powered by Mazda’s hydrogen rotary engine mated to a hybrid system, the Premacy Hydrogen RE Hybrid is scheduled to start commercial leasing in Japan in fiscal year 2008. (Earlier post.)

Mazda began joint activities with the research department at Hiroshima University’s Graduate School of Engineering in 2005. This partnership’s comprehensive agreement on joint automotive technology research includes biomass technology. Going forward, Mazda plans to expand the collaborative research on biomass technologies and strengthen its relationship with Hiroshima University for multidisciplinary joint research. Japan’s National Institute of Advanced Industrial Science and Technology (AIST) will also participate in the bioplastic project as part of its ongoing agreement to collaborate on biomass research with Hiroshima University.



Plant Plastics. Wonderful.


I am waiting for a hempmobile capable of medium speed electric drive and 60 mile range, as safe as a Fiat 500.
