History

  • 1913The first continuous-production-type salt electrolysis technology was developed by Mr. Chiwaki Kadota of Japan, who later became the first technical director of Osaka Soda Co., Ltd. ("Osaka Soda"), the former name of Daiso Co., Ltd. ("Daiso's Mercury-Based Soda Electrolysis Process").
  • 1915Osaka Soda was established in Osaka with the objective of manufacturing and selling caustic soda and its related products.
  • 1917The operations began at Osaka Soda's Kokura Electrolysis Plant in the city of Kita-Kyushu, Fukuoka Prefecture, Japan.
  • 1931The operations began at Osaka Soda's Amagasaki Electrolysis Plant in the city of Amagasaki, Hyogo Prefecture, Japan.
  • 1952The operations began at Osaka Soda's Matsuyama Electrolysis Plant in the city of Matsuyama, Ehime Prefecture, Japan.
  • 1969The Technology Prize was awarded to Osaka Soda for its mercury removal technology, later known as the MR System, by the Japan Soda Industry Association.
  • 1970Okayama Chemical Co., Ltd. was established by Osaka Soda jointly with a third party (on a 50–50% basis), and the operations began at its Mizushima Electrolysis Plant in the city of Kurashiki, Okayama Prefecture in Japan.
  • 1975Daiso Engineering Co., Ltd. ("Daiso Engineering") was established by Osaka Soda in Osaka City as its wholly owned subsidiary, Daiso Engineering, with the objective of selling to Osaka Soda and its group companies, as well as other third parties, the electrolysis and organic chemical technologies developed and acquired by Osaka Soda through its 60-year history of electrolysis plant operations.
  • 1978Daiso Engineering absorbed Daiso Koji Co., Ltd., a wholly owned construction company of Osaka Soda, for expanded engineering operations.
  • 1986All of Osaka Soda's electrolysis plants were prepared for conversion from mercury-type electrolysis to ion-exchange membrane processing.
  • 1988The name of Osaka Soda was changed to Daiso Co., Ltd.("Daiso").
  • 1994Daiso began manufacturing and selling electrodes for salt electrolysis plants to third parties.
  • 1999The Chemical Technology Prize was awarded to Daiso from the Chemical Society of Japan for its development of high-durability anodes for electrogalvanizing.
  • 2001JMR Co., Ltd. was established by Daiso Engineering as its wholly owned subsidiary with the objective of recycling waste fluorescent lamps.
  • 2002Daiso took over the metal electrode business from TDK Corporation.
  • 2008All of Daiso's electrolysis business interests were transferred to Daiso Engineering from Daiso, for consolidation by Daiso Engineering, based technical developments and improvement of the electrodes and also for expansion of the electrolysis business and other associated systems.
  • 2011Daiso Engineering participated in the technical development and assistance of lithium recovery technologies for Bolivia, one of the trade investment support projects sponsored by the Ministry of Economy, Trade and Industry, Japan.
  • 2012A high-efficiency bipolar electrolyzer was introduced by Daiso Engineering at Daiso's Matsuyama electrolysis plant for evaluation of various electrodes applied to the latest commercial operation plant.
  • 2013Daiso Engineering presented its mercury-removal technology at the Minamata Convention on Mercury held in Minamata, Kyushuu Island, Japan.
