Turning Tree Life into Fuel: The Future of Bioenergy Led by Yeast (January 2009)

Turning Tree Life into Fuel: The Future of Bioenergy Led by Yeast (January 2009)

The National Institute of Beverages Research (Higashihiroshima City, Hiroshima Prefecture) is developing a new technology to efficiently refine biodiesel fuel (BDF) from woody biomass. The new technology is based on a process that uses enzymes used in shochu production to extract sugars, which are then converted into BDF by oil-producing yeast.

Theoretically, approximately 34 grams of BDF can be obtained from 100 grams of raw material. Since fiscal 2009, companies have been participating in this research to solve problems such as improving the conversion speed and yield rate. This technology, which efficiently converts unused woody biomass into renewable energy, will expand the possibilities of recycling local resources and fuel self-sufficiency.

The social implementation of this technology will also help to secure energy in times of disaster and build the foundations for a sustainable society. The challenges being taken on by the National Institute of Beverages Research are certainly beginning to illuminate the future of both local production for local consumption of energy and reduction of environmental burdens.
