Chlor-Alkali

Providing the world with basic chemicals that broadly support industry.

Supporting Industry by Supplying Basic Chemicals

Chlor-Alkali is the source of Nippon Soda’s diverse chemicals. From the time of our founding in 1920, we have continued to provide a variety of basic chemicals centered on caustic soda and chlorine. We have expanded our product variations hand in hand with the development of industry in Japan, and we now provide an extremely wide range of products domestically and abroad. Our product line includes caustic soda, chlorine, hydrochloric acid, caustic potash, potassium carbonate, sodium cyanide and phosphorous compounds. We will continue to utilize our unique technologies cultivated over many years, focus on providing increasingly high quality, high value added and safe products, and respond to the expectations of the industrial society.

TOPICS

Establishing treatment technologies by detoxification of PCBs with the SD method

Formerly used in transformer oil, the manufacture, use and importation of polychlorinated biphenyls (PCBs) was completely prohibited after their toxicity became apparent, but the treatment of products containing PCBs had become a problem. Consequently, in 1995, the Nippon Soda group developed our unique treatment technologies by detoxification of PCBs, the SD (sodium dispersion) method.
Treatment is possible at low temperatures, under normal pressure and in a short time, allowing for simple treatment facilities and on-site treatment.
Due to these merits, it is now used at the Japan Environmental Safety Corporation’s (JESCO) business establishment in Kitakyushu and private power companies.
