Sludge field

Penta is behind the largest private investment in the removal of environmental burdens in Slovakia. Sludge field in the city of Žiar nad Hronom was one of the biggest environmental threats in Central Europe.

In 2002, when we entered the ZSNP company, we committed to the reclamation of the sludge field, which contained several million tons of alkaline substances and threatened to spill sludge into the Hron River and the surrounding groundwater.

We started the reclamation of the sludge field in 2004 and completed it in 2012. During that time, we managed to clean more than 2.5 million cubic metres of alkaline water and prevent the leakage of substances into the surrounding area. The sludge field continues to be under our care and we have invested more than €50 million in its reclamation. We also won the ENVIRO OSCAR award in the ENVIRO TECHNOLOGY OF THE YEAR category.
