The BPI Certification Mark indicates third-party verification of compostability for manufacturers and brand owners to use on products and packaging and for consumers, end-users, and composters to use when determining whether or not a product or package is compostable. BPI is the only third-party verification of ASTM-6400 or ASTM-6868 standards for compostable products in North America.
In order to achieve BPI Compostable accreditation, materials need to meet the following requirements in an industrial compost environment: - Minimum of 90% biodegradation of bioplastic materials within 180 days in compost. - Minimum of 90% of plastic materials should disintegrate into less than 2mm pieces in compost within 90 days. - Hazardous substances such as heavy metals should not be present above the maximum allowed levels. - Plastic materials should contain more than 50 percent organic materials.
