General Description of the Research Project

Contribution to mitigating climate change by using existing resources effectively
There is increasing demand for bioethanol fuel produced from crops such as sugarcane and corn as an effective means for mitigating climate change without increasing the amount of CO2 in the atmosphere. However, there can be problems such as deficiency of raw materials due to competition with food and feed use, rising food prices, and deforestation due to increased cultivation area of crops. For these reasons, research and development is underway for the production of bioethanol from the bagasse that remains after the sugarcane is crushed to collect cane juice, and from wastes like straws. Bagasse and straws have rigid structures and contain components that cannot be converted into ethanol.

Construction of optimum fuel ethanol production system for the use of bagasse and straws
In addition to developing technology for breaking down the rigid raw materials with small energy input, a new yeast strain has been developed for fermentation. The goal of this project is to contribute to mitigating climate change through sustainable fuel production, and extension to other regions such as Southeast Asia is also planned.

Brazil is already producing ethanol from sugar cane juice, but the use of wastes will result in more effective climate change prevention.
