Slag Recycling is one of the biggest producers of metallurgical aggregates and iron skull scrap in Poland. The company was established in February 1998 as a joint venture of the Tadeusz Sendzimir Steelworks S.A. and British Consortium: Central European Recovery Holdings. Within a few years it has become the largest pro-ecological investment in Poland.

Slag Recycling exploits a metallurgical slag dump deposited in Pleszew near Cracow, as well as a dump belonging to Kościuszko Steelworks in Chorzów, processing wastes into full-value products and thus preserving natural environmental resources.

The mission of the company is post-industrial land restoration and supply of the highest quality raw materials destined for road building, building industry and metallurgy in Poland.
