Sustainable solutions for wine waste

Sustainable solutions for wine waste

Ways to recycle the vast amount of plant waste produced by the wine industry are under investigation by chemistry and biotechnology researchers at Swinburne. Grape pomace is the skins, pulp, seeds and stems remaining after the fruit has been pressed for juice. While pomace contains tartaric acid, a common additive used to balance the acidity of the wine, it is of limited nutrient value. It is also too hard for animals to digest so can’t be used as feed, and degrades too slowly to be useful as compost.
