History of Japan Sea Refining (1981-1994)
I will introduce our company's journey so far.
The main business of Nihonkai Seiren is the secondary refining of lead resources. Throughout the development of our business, we have contributed to the community as a member of a circular society. We believe that we play a role in the recycling business in modern society, where the effective regeneration and reuse of limited resources is required. Here is an introduction to our journey in developing the secondary lead refining business in Maizuru. ■ December 1981 Achieved a product base of 500 tons/month for recycled lead refining. ■ December 1982 Withdrawn from the lead scrap division. ■ August 1983 The lead division was separated and became independent from Ryotan Shoji. At the same time, Nihonkai Seiren Co., Ltd. was established. At this time, the headquarters was located in Hirano, Maizuru City, with the first factory in Hirano and the second factory in Kokura, and we began our business. ■ 1994 The electrolysis plant was completed. On August 1 of the same year, it was energized. Subsequently, it operated at a pace of 700 tons/month for electric lead production. We started with a monthly production capacity of 300 tons and achieved an electric lead purity of 99.999%.
