I don’t think it’s a small effect. There are something like 300 million tons of plastic waste per year, which is about 1 Gigatonne of CO2, or about 3% of global emissions… more than global aviation!

If we cut down all sources of emissions to zero, that would mean humanity using non-fossil plastic (like PLA or electrolytic syngas derived regular plastics) would be carbon negative.

The cost of PLA is about $2/kg, or equivalent to about $600/tonneCO2. About how much Climeworks currently costs for direct air CO2 capture.

It's probably even better than that, if the PLA cost is for ready-to-use PLA, because presumably dirty/unprocessed PLA costs even less.
