In 1931, Showa Denko succeeded in producing ammonia and ammonium sulfate by using Japan's first production method in its Kawasaki Plant. Since then, the company has accumulated a long history of developing and producing products in the fields of organic and inorganic chemicals. Its original products consisted of general-purpose industrial gases, medical gases, and industrial chemicals. In recent years, the company has also come to provide a variety of products including high-purity gases and chemicals for the semiconductor industry. In an effort to respond to overseas shifts of the semiconductor industry, moreover, Showa Denko promoted overseas operations of producing specialty gases and specialty gases equipment, with the result that it has already established overseas bases in Shanghai and Singapore.
We are operating Japan’s sole plant that produces ammonia from used plastic in an effort to contribute to the formation of a resource-recycling society.
