Bio-based polymers are materials made from renewable biological resources, such as plants and microorganisms. Unlike traditional plastics derived from fossil fuels, these polymers can be produced from materials like corn, sugarcane, and cellulose. They offer a more sustainable alternative, reducing reliance on non-renewable resources and minimizing environmental impact. These polymers can be used in various applications, including packaging, textiles, and automotive parts. Examples of bio-based polymers include polylactic acid (PLA) and polyhydroxyalkanoates (PHA). As technology advances, the development of bio-based polymers continues to grow, promoting a circular economy and reducing plastic waste.
