Grape Crop Waste and Valorisation

Report: The potential of grape by-products for a biobased circular economy



Details


This report explores the potential use for viticulture waste and crop by-products from wine production.


The growing English wine industry produces large amounts of grape pomace, wastewater, yeast lees, and vine prunings. Key sustainable strategies for managing

wine waste include composting, bioenergy production through anaerobic digestion,

and nutrient recovery.


Grape pomace and yeast lees offer potential in high-value applications, such as animal feed, skincare products, and bioethanol production. Proper management of these waste products is crucial to minimise environmental impact and maximise resource use.


This report is an extract from a wider publication looking at the potential for agricultural and horticultural waste for a biobased circular economy in South East England. The full report explores opportunities for vegetable, fruit, hop, cereal, and mushroom waste valorisation.
