Sojitz Corporation (“Sojitz”), together with Tokuyama Corporation (“Tokuyama”) and NanoMist Technologies Co., Ltd. (“NanoMist Technologies”), has been notified that it will be selected for a New Energy and Industrial Technology Development Organization (“NEDO”) consignment project designed to develop and propagate carbon recycling technologies: “Development of Technologies for Carbon Recycling and Next-Generation Thermal Power Generation / Development of Technologies for CO2 Reduction and Utilization / Development of Technologies for CO2 Utilization in Carbonates, Concrete Products, and Concrete Structures.”

This is a three-year project that will run through the 2022 fiscal year. The project seeks to achieve the cost reduction of CO2 separation and capture, as well as its reuse, which are technological issues announced in the Ministry of Economy, Trade and Industry’s roadmap*1 for carbon recycling technologies. Currently, CO2 derived from limestone combustion is used as a raw material in the production process of carbonates (soda ash). But in this project, it is our aim that CO2 in the combustion exhaust gas of coal-fired power plants can be absorbed by a technically developed NanoMist*2 and used as a replacement raw material for carbonate production, thereby reducing CO2 emissions.

Through this project, Sojitz will try to solve social issues in countries around the world by realizing the early implementation of carbon recycling in society with new Japanese-developed technologies.

As a global company, Sojitz Group considers environmental issues a crucial topic to be addressed in its management moving forward. Striving for a sustainable society, we will work to preserve the environment and prevent pollution in our business activities, while creating businesses that are both highly competitive and environmentally friendly.

<Roles of each company>
・Sojitz         :Project management, feasibility evaluation, LCA evaluation
・Tokuyama       :Development of CO2 extraction technology, engineering work
・NanoMist Technologies:Development of CO2 absorption technology using a fine mist
・All three companies  :Formulation of conceptual designs, development of CO2 absorbent materials

*1)Announced in June 2019, the roadmap identifies cost reduction for separating and capturing CO2 as a technological target to be reached by 2030 (1,000 to 2,000 JPY per ton of CO2).
*2)Originally developed by NanoMist Technologies, ultrasonic waves are used to atomize an aqueous solution to a particle size of five micrometers or less. By making the solution into a ‘NanoMist’, the surface area is increased, thereby improving CO2 absorption efficiency and reducing costs.
