Breakthrough Found: Grapevines Could Offer Alternative to Plastic Packaging
—————————
Researchers at South Dakota State University (SDSU) have developed a biodegradable film from a common agricultural byproduct—grapevine prunings—that could serve as a sustainable alternative to plastic packaging, Earth.com reported.

The new film is made from cellulose extracted from grapevine canes, which are typically pruned and burned each winter. The research, led by Associate Professor Srinivas Janaswamy, aims to address the widespread problems associated with conventional plastics, such as their petroleum-based origin, resistance to degradation, and contribution to microplastic pollution.

The resulting film is transparent and strong, with the ability to biodegrade in soil within just 17 days without leaving behind any harmful residue. This makes it an ideal material for single-use packaging. The use of agricultural waste adds value without requiring new land or water resources, contributing to a circular bioeconomy. The next steps for the team will be to scale up production and ensure the film meets food-contact standards.
