The BPI Certification program is the only third-party verification of ASTM standards for compostable products in North America.The certification program was developed to apply science-based testing to prove a material will compost in a municipal or commercial facility.The Certified Compostable program uses a specific set of testing criteria published by the American Society for Testing and Materials (ASTM).
