  • About

winery waste, comprises the liquid and solid waste that results from the process of turning fruit into wine. Globally the wine industry has been working to establish sustainable systems to deal with both these waste streams so as to maintain the beautiful rural environments in which wine is typically made. In many wine regions, there are now stringent local and sometimes national guidelines, policies, and legislation covering this area.

Water is a by-product of the hygiene or sanitation required to make wine, for example washing tanks, fermenters, and barrels. Roughly 1.5 volumes (litres/gallons) of water is used in the production of 1 volume of wine, though the exact amount depends on winemaking processes, winery equipment, and winery practices. Over a year, about 70% of the total volume of waste water generated is during the vintage period, so sustainable waste-water systems need to be designed to handle these loads at this time.
