BorsodChem – a member of the Chinese Wanhua group – has started preparations to replace its existing 125 kt/year capacity mercury-based chlorine unit in Kazincbarcika, Hungary, with a more energy-efficient and environmentally-friendly membrane plant. The project is expected to be completed by December 2017. The company already operates a 195 kt/year membrane unit, and with the replacement of the mercury plant, BorsodChem will maintain its position as the leading producer of chlorine and caustic soda in the region.

Chlorine is used internally to feed BorsodChem's production of MDI, TDI and PVC, while caustic soda is sold externally to a variety of industries. In order to guarantee smooth and stable supplies, a new 8000 m3 tank for caustic soda is under construction, operational from January 2015.

With these investments, BorsodChem aims to ensure sustainable production of raw materials and to improve the quality of its services.
