Biodegradable fillers are materials used in various products to enhance their properties while being environmentally friendly. Unlike traditional fillers, which can persist in the environment for years, biodegradable fillers break down naturally over time. They are often made from renewable resources such as corn starch, cellulose, or plant fibers. These fillers are commonly found in applications like packaging, construction, and personal care products. By using biodegradable fillers, manufacturers can reduce their ecological footprint and contribute to sustainability efforts. As awareness of environmental issues grows, the demand for these eco-friendly alternatives continues to rise.
