Grape Waste-Based Hydrogels: Production, Properties, and Applications

Abstract

Grape waste-based hydrogels represent a sustainable and innovative approach to waste valorization, offering remarkable properties for diverse applications. Derived from grape pomace, skins, and seeds, these hydrogels exhibit excellent water retention, biodegradability, and tunable mechanical strength. Their multifunctional nature enables applications in agriculture, biomedical fields, and environmental remediation, including controlled drug release, wound healing, and wastewater treatment. The incorporation of polyphenols and bioactive compounds further enhances their antioxidant and antimicrobial properties. As eco-friendly alternatives to synthetic hydrogels, they contribute to circular economy strategies and sustainable material development.
