CELYS™ Compostable Certifications

The BPI Certification program is a third-party verification of ASTM standards for compostable products in North America.

Certificate No. 10529267-1


DIN CERTCO from Germany is an independent certifier of compostable products.

Registration No. 9K0130


The Seedling logo is a registered trademark owned by European Bioplastics (i.e. EUBP).

Registration No. 7W0801


The BPI Certification Mark indicates third-party verification of compostability for consumers, end-users, and composters to use when determining whether or not a product or package is compostable.

NOTE: Please make sure your final product, say a garment, is BPI certified before you use the BPI Certification Mark for consumer-end promotions, although CELYS™ fibre, as an ingredient fibre, has obtained BPI certification.
