Obviously I need to repeat the question as I have not yet gotten an answer.

So, I ask again, since oil (or other forms of energy, natural gas...) is consumed as a reactant and for energy to drive the reaction to make plastics,

So then, why would I waste energy to unmake the plastic and turn it back into oil?

Why not recycle the plastic as plastic using less energy?

I know of no plastic scrap that can not be recycled into plastic products.

The answer is not that challenging.

If you have actual thermodynamic data and verifiable links to justify your claim, then lets see them please.
