Interesting question. I do know that expanded Polystyrene (EPS) is made from residual acids from the refining process. It was invented by the Germans in WWII. As a waste material source there is a choice between EPS and huge lakes of toxic acids.
Obviously there is a need to reduce petroleum use in concert with the production of plastics.

Assume the best and ask questions.
