> Also, what you said isn’t necessarily true even with plant based resins. What is the carbon cost of producing new resin vs recycling old?

In the post-fossil fuel age, where is the net carbon supposed to be coming from? Unless we're using limestone, it's from the air, so there can't be net emission.

In the not-yet post-fossil fuel age, what matters is displacing fossil fuels as quickly as possible, not the relatively very minor amount of carbon embodied in the renewable energy machinery.
