BioBag®  compostable bags are Compost Manufacturing Alliance (CMA) approved and accepted for Cedar Grove Residential and Commercial Organics Recycling Streams.

BioBag compostable bags have been accepted at Cedar Grove, and in King County/Seattle or over a decade. You can learn more about King County’s program here.

Please be aware that BioBag is one of a few brands accepted into this program because of our validation to compost efficiently and effectivity by the Compost Manufacturing Alliance (CMA). 

Buying ‘online’ only brands, whom are mostly manufactured in Asia, will not be accepted and could be rejected.

Why/About CMA
Compost Manufacturing Alliance (CMA) is a global leader in providing industrial composting facilities an acceptance standard for compostables by performing field disintegration testing. Not all ‘certified’ compostable items will compost (break down) as fully or quickly as needed. This is because traditional certification standards measure compostability based on laboratory conditions, not actual field conditions, therefore some “compostable” items don’t fully compost.
