The winery industry produces every year in the world about 270 millions of hectolitres of wine. A consequent amount of grape marc is then generated that has to be somehow treated and processed. For this reason a technique to treat grape marc (bio-drying) was studied and applied at the University of Trento. Grape marc, as is, is not suitable for direct combustion because of its high water content. By bio-drying the lower heating value has been increased up to the limit for a good combustion. This result allows a decentralized management of a grape marc drying differently from the conventional solutions.
