Polylactic Acid (PLA) is a biodegradable and bioactive thermoplastic made from renewable resources like corn starch or sugarcane. It is commonly used in 3D printing, packaging, and disposable items due to its environmentally friendly properties. PLA is known for its ease of processing and ability to decompose under industrial composting conditions. PLA is produced through the fermentation of sugars into lactic acid, which is then polymerized to form long chains. This material is popular in the manufacturing of bioplastics, offering a sustainable alternative to traditional petroleum-based plastics. Its applications extend to medical devices and food packaging, promoting a circular economy.
