Managing By-Products of vitvinicultural origin

There is increasing interest in the valorization of secondary products generated at different points and stages of the production chain in the grape and wine industry. Discussions have taken place on a number of occasions at state and local government level about the accumulation of secondary products and their possible negative environmental impacts. In vitivinicultural regions that generate large volumes of secondary products, their removal is becoming not only an environmental and ecological problem, but also an economic one, which can reduce competitiveness of the entire sector.

Chattopadhyay et al. (in Poonam Singh nee’ & Pandey, 2009) estimated that the production of 100 Kt of must/ wine will cause 38.9 Kt of wine grape secondary products.
