Researchers at the Kharagpur Institute of Technology in India have developed cellulose nanocrystals from cucumber peel, a by-product of the beverage industry, which can be used in the production of food packaging materials. These nanocellulosic materials are renewable, strong, and economically viable, with unique properties such as high surface area / volume ratio, light weight, and excellent mechanical properties. They are also biodegradable and biocompatible, making them suitable for food packaging.
