I manage an urban composting site and we frequently get compostable bags. Our site generates enough heat to semi-reliably break down the bags, but do they actually break down the same as organics? Do they just turn into microplastic faster?
The main certifying body (in the US anyway) is BPI who actually have their criteria posted:
https://bpiworld.org/BPI-Certification-Scheme
I couldn't find any methodologies that specifically addressed microplastics, but its also a bit above my reading level.
Any information would be exceptionally valuable and will help guide us on what we accept at our site. Thank you!
