The operation carried out at the treatment plant in Grosseto, instead, was the first project for the supply and installation of the Newlisi system. The project involves the processing of sludge produced by some nearby treatment plants being centralised in the Grosseto plant, which serves as a hub for treating the sludge and sending it to its final destination. The plant, which started up in August 2021, achieved a sludge reduction of about 65% without an anaerobic digester.
