Abstract: Apparatus and methods for improved composition of floor coverings, utilizing bio-renewable materials, is disclosed. Floor coverings, or tacky mats, may be used in cleanroom environments to capture particulate matter from foot and equipment traffic. Bio-renewable materials may include thermoplastic starch (TPS) blends made from sustainable raw materials such as corn, tapioca, or the like. These bio-renewable materials may be blended and coextruded with synthetic or petro-based polymers. This reduces the environmental impact on production and disposal of the floor mat, while maintaining the physical and mechanical properties demonstrated by pure synthetic polymers.
