MOSCOW (MRC) -- Tosoh Corporation managed the parties in joint proposal of “development of technology for producing raw materials for plastics using CO2 and/or other sources” selected by Japan’s New Energy and Industrial Technology Development Organization (NEDO) funded by the Green Innovation Fund, according to SpecialChem.
Tosoh’s proposal collaborators include Mitsubishi Gas Chemical Company, Inc., the Interdisciplinary Research Center for Catalytic Chemistry at the National Institute of Advanced Industrial Science and Technology (AIST); Professors Keiichi Tomishige and Yasuhiro Fukushima, of Tohoku University Graduate School of Engineering’s Departments of Applied Chemistry and of Chemical Engineering, respectively; Professor Masazumi Tamura, of Osaka City University’s Research Center for Artificial Photosynthesis; and Colcoat Co., Ltd.
These parties will now collaborate in aiming to reduce CO2 emissions during the manufacture of polycarbonate and polyurethane by eliminating from the process the need for the conventional raw material phosgene.
They will, moreover, strive to achieve technology to convert CO2 into a raw material for plastic production by 2030. Their hope is to achieve the same plastic manufacturing cost as currently while improving the functionality of the plastic produced. To those ends, they will pilot the production of several hundred to several thousand tons of plastic per year.
The Japanese government’s goal of carbon neutrality by 2050 looms large in this project’s efforts to develop technology to capture CO2 for use as a raw material for plastic. Using CO2 in place of phosgene as a raw material to produce dialkyl carbonate and isocyanate, the raw materials for polycarbonate and polyurethane, will reduce CO2 emissions well below those generated with phosgene.
This project will also accelerate the development of manufacturing technology for functional chemicals using CO2 as a raw material. To ensure the widespread future use of that technology, the project collaborators will conduct a life cycle assessment of the chemicals it yields.
Project partner Mitsubishi Gas Chemical Company will use CO2 as a raw material to develop an intermediate for the polycarbonate manufacturing process that emits fewer GHGs than conventional processes.
By applying this technology to the development of high-performance polycarbonate, Mitsubishi Gas Chemical Company aims to develop and demonstrate functional chemical manufacturing technology for polycarbonates (PC) on a commercial scale toward achieving carbon neutrality by 2050.
As MRC informed earlier, Tosoh Corporation, a major Japanese petrochemical producer, has announced it will permanently stop producing and selling toluene diisocyanate (TDI) and TDI-related products from its Nanyo complex in Japan, effective April 2023. Despite the continuous implementation of measures to improve profitability, the environment surrounding this business has become increasingly severe in recent years, and there are no prospects for improvement, the company stated. Tosoh currently produce 25,000 t/y of TDI at the site.
Founded in 1935, Japan's Tosoh Corporation, headquartered in Tokyo, is an international chemicals and specialty materials company. The main activity of the company is the production of chlor-alkali and petrochemical products, which include ethylene, propylene, polypropylene, polyethylene and synthetic rubbers. The Tosoh Group globally includes over 130 companies with manufacturing facilities and offices in Japan, China, the Philippines, Indonesia, Singapore, Taiwan, South Korea, Germany, Belgium, Holland, Italy, UK, Greece, Switzerland and the USA.
