Bio-based materials are substances derived from renewable biological resources, such as plants, animals, and microorganisms. These materials can include products like bioplastics, biofuels, and natural fibers, which are used in various applications, from packaging to construction. They offer an alternative to traditional materials made from fossil fuels, helping to reduce environmental impact. The production of bio-based materials often involves processes that are more sustainable and can lead to lower carbon emissions. By utilizing resources that can be replenished, such as corn or sugarcane, these materials contribute to a circular economy, promoting the use of renewable resources and reducing waste.
