    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?

        If it gets incorporated into the soil then some will stay there. Plus many landfill designs prevent decomposition entirely

          Well yea, but they claim the point is that it’s not going to need to end up in landfills because it biodegrades. Meaning at best it’s carbon neutral, but that’s unlikely unless only renewable energy is used it produce it in the first place.

          Don’t get me wrong, it sounds miles better for the earth than making more microplastics, but it’s not much more than that, and not some kind of panacea.

        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.
