“The raw materials for epoxy resin production are today largely petroleum derived, although some plant derived sources are now becoming commercially available (e.g. plant derived glycerol used to make epichlorohydrin).”

if they were obtained from non-fossil sources - but they weren’t, and the industry hasn’t switched and may never switch to plant based.
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?
There’s more to the impact of a material than the carbon stored inside it.
Yes, we were all duped by the recycling industry. No that doesn’t make all attempts at recycling a lie.

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.
It seems to me you’re thinking of this in wayyy to much of a binary. It’s not pre-fossil fuel vs post fossil fuel - it’s how do we transition each thing we use fossil fuels for.
Like if we end fossil fuels for energy, the cost of plastics will skyrocket. They maybe don’t contain enough carbon on their own to drive global warming, but we still need alternatives because otherwise that’s a many-billion dollar industry that is going to oppose stopping burning fossil fuels for energy.
