More than 8 million tons of wastewaters in Italy

40% are processed through chemical-physical plants: a very old and messy technology, still the industry standard.

Metals are separated through sludge precipitation, which is then sent to landfills.

Sludges still represent 20-35% of initial water volumes. The problem is NOT solved but, moved to the landfills.

Progressive saturation of existing landfills and the stricter rules are pushing up the cost of sludge disposal.
