I hope this is true but I remain skeptical of the initial claims. PLA is supposedly biodegradable as well, however in practice, it only biodegrades under very specific circumstances that are tricky to sustain without putting a good amount of work and planning in.

Regardless of whether or not it truly biodegradable, switching from oil to a plant based plastic is a carbon sink.

I'd imagine it's also better than having microplastics in my balls. Bamboo polymers in the brain sounds less threatening.

Plus if it biodegrades in 300 years that's still way better than what we are doing

Isn’t it only a carbon sink if you keep microbes from digesting it?

Is there a biodegradation of it that doesn’t release co2?

[–] sga@piefed.social 3 points 4 weeks ago

if it enters eco system back, its biodegradation. more technically, biodegradation just means breaking polymers by biological processes. most of the times, it either means hydrolysis (usually breaking ester/amide linkages) or oxidation (so producing acid from alcohol, or producing co2 in end). all carbon in body "eventually" becomes co2, so it is not a problem, purely biological means of co2 production are usually not that scary.
