Consumers, End-Users, Composters, and others use the BPI Certification Mark to determine whether finished items are compostable. Using it properly is essential to helping mitigate contamination from non-compostable products in organics streams. The following are examples of improper use of the BPI Certification Mark:
Use of the BPI Certification Mark may not meet the requirements to make claims of home compostability in all states in the United States. In Maryland, MD Environment Code § 9-2102(b)2, established by House Bill 1389 in 2017, requires items labeled as “home compostable” to meet the OK compost HOME requirement adopted by Vincotte. In California, section 42357(a)(4) of Assembly Bill 1201, adopted in 2021, states, "A product shall not be labeled with the term “home compostable” unless the manufacturer of that product holds OK compost HOME certification." BPI is working to have BPI Certification accepted in these two states to support claims of home compostability, as the BPI Home Compostability Certification Scheme is more restrictive than OK Compost HOME certification. Nonetheless, licensees are responsible pursuant to the terms of the licensing agreement between licensee and BPI for ensuring their products are compliant with the requirements of markets where such products are sold.
