Honestly, I love 3d printing, but I still worry about microplastics in the environment.
It's complicated but PLA is bio-degradable ... eventually. Not months but years. That's much better than the horrors you see on Blue Planet II.
PLA requires industrial high heat composting to breakdown. Otherwise it will be around as long as any other type of plastic.
Is this true also for microplastics? I am aware of the marketing claims and the helpfull oversight of the needed bioreactor but i thought that was in part due tl the larger pieces. Wondering about micro
I’m not sure how much sooner it degrades, but the study still suggests that it causes cellular damage before it’s able to degrade.
