Poly-L-lactic acid (PLLA) is a biodegradable polymer derived from renewable resources, specifically corn starch or sugarcane. It is commonly used in medical applications, such as sutures and tissue engineering, due to its biocompatibility and ability to degrade safely in the body over time. In addition to medical uses, PLLA is also utilized in the production of biodegradable plastics and packaging materials. Its properties allow for a sustainable alternative to traditional petroleum-based plastics, contributing to efforts in reducing environmental impact and promoting sustainable development.
