Since 2014, a 2.6 Mw cogeneration plant has been in operation in the Bosco Marengo Spa paper mill. In its first year, the plant has allowed for an electrical efficiency of 44% and a thermal efficiency of around 37%. A great result for the company which declares to be very satisfied with the investment made. A Siat RECOPACK heat recovery boiler was installed to complete the plant, fitted out with extra equipment which guarantees great results and full safety.
