History


In 1912, Tsuneichi Fujiyama founded a carbide business, Hokkai Carbide, in Tomakomai, a village in Hokkaido. One year later, Fujiyama patented his own process of producing cyanamide, the continuous cyanamide process. In 1913, Fujiyama with the help of 22 venture capitalists incorporated a reorganized Hokkai Carbide as Denki Kagaku Kogyo, the current company. Despite its legal status as an independent corporation, Denka was a Mitsui-related company. The company changed its name from Denki Kagaku Kogyo to Denka Company Limited 2015.




Pontchartrain Works


The Pontchartrain Works facility owned by Denka in Reserve, Louisiana has been reported to be emitting chloroprene which is defined as "likely to be carcinogenic to humans" by the EPA. Up to 755 times the safe air value of 0.2 μg/m3 of chloroprene has been recorded at the fifth ward elementary school in close proximity to the plant. The cancer risk in Reserve is 1,500 times the national average and is thought to be due to chloroprene levels. Denka has replied to the reports as being not based on "sound science".
