Abstract:
From the vineyard to the bottle, the winemaking process generates a variety of by-products, such as vinasses, spent filter cakes, grape pomace, grape lees, and vine shoots. To avoid damaging the environment and to reduce economic impacts, the by-products and wastes must be handled, disposed of, or recycled properly. This review focuses on an environmentally friendly approach to the management and added value of winemaking by-products, such as grape pomace or grape marc, by using vermicomposting. Vermicompost is a well-known organic fertilizer with potential uses in soil bioremediation and the conservation of soil health. To achieve environmental neutral agriculture practices, vermicomposting is a promising tool for resilient and sustainable viticulture and winemaking. Vermicomposting is a simple, highly beneficial, and waste-free method of converting organic waste into compost with high agronomic value and a sustainable strategy in line with the principles of the circular economy.
