The company was established in 1996 on the base of restructuring of the state company mine Kopalnia Węgla Kamiennego Thorez w likwidacji.

Since its establishment the company sells coal sludge which were waste of coking coal flotation process. Coal sludge were, in relation to flotation of the coal extracted from the mine Thorez, stored from the thirties of the last century until 1996, when the mine stopped mining.

Coal mined below ground is not a pure product – contains small fragments of rock that must be removed. This is achieved by a process for upgrading coal. It runs in the aquatic environment and its effect – except enriched – cleaned coal – is a waste – coal sludge. Due to the fact that the process was far from perfect, coal sludge contains large amounts of coal. In addition, our sludge comes from enrichment processes locally mined anthracite, which determines its high heating value.
