Thank you for the link.
I have a feeling these shells will degrade in less than 90 days, thanks to the bacteria having a lot more surface area to work on. My guess is there would be a similar volume of plastic in one of these paintballs to a BB.
This sentence "One big difference with ECOBBs, is unlike past PLA formulas, ECOBBs are not particularly light sensitive and light does not trigger the decomposition process" seems to suggest PLA is photodegradable as well. Is this true?
