In Italy Zoogamma, a Van Drie Group company, operates in the animal nutrition sector and, in the Casalbuttano branch (in Lombardy), it transforms whey into powder for the production of feed. Over the years, the branch has increased its production and expanded its spaces, with a consequent increase in energy needs that was satisfied with the installation of a first trigeneration plant which, in 2018, was joined by a second one. The company’s considerable expansion efforts, including in the food sector, has in fact necessitated a greater input of energy and heat for the production process. The expected performance of both plants has been confirmed not only from an economic point of view, but also from an environmental point of view, with a considerable decrease in CO2 emissions.
