Biodegradable coatings are protective layers made from natural materials that can break down over time in the environment. These coatings are often used in packaging, agriculture, and food products to reduce plastic waste and promote sustainability. They can decompose into harmless substances, minimizing their impact on ecosystems. These coatings can be derived from sources like starch, cellulose, or proteins. Unlike traditional coatings, which can persist for hundreds of years, biodegradable options offer a more eco-friendly alternative. As industries seek greener solutions, biodegradable coatings are gaining popularity for their ability to provide protection while being environmentally responsible.
