Citizen scientist Rob Cockerham decided to test SunChips’ claim that its bag disintegrates in a compost pile. His conclusion:
The SunChips bag didn’t disintegrate in my compost pile, and I doubt they will disintegrate in any home compost pile. In 25 weeks, most of the other material in the pile had completely broken down, which might actually halt what little decomp was occurring on the bag itself.
Does the SunChips Bag Really Break Down in a Compost Pile?
