"BPI Certified" refers to products verified by the Biodegradable Products Institute (BPI) as meeting specific standards for industrial compostability, meaning they will break down in commercial composting facilities without leaving harmful residues. The certification program provides third-party verification that products meet ASTM International (American Society for Testing and Materials) standards, such as ASTM D6400, ensuring they decompose into carbon dioxide, water, and biomass within a defined timeframe under industrial composting conditions.
