One point is not clear to me though. Are the benzene amounts from fuel production sufficient for all plastic manufacturing or are they in short supply nowadays because of the risen demand for plastic? Or are they just shifting around their processes to be less fuel optimized to create enough plastic precursors if needed?
So, it’s not just benzene but a whole cocktail of aromatics (carbon molecules with rings in them) in addition to the ethane which is used to make poly ethylene plastic.
To answer your question, no, they never alter production for the sake of making more plastic, rather changes in production are driven by the availability of certain types of crude oil (heavy vs light, sweet vs sour) and demand for certain types of fuel. These changes result In more or less production of plastic precursors as a side effect.
Demand for plastic is almost entirely driven by the availability of the precursors, more supply means a lower price, means more uses for plastic become cost effective and displace other materials. They make far more money selling fuels than they do selling plastics. The margins on fuels are much higher as plastic requires additional inputs, additional manufacturing/processing, and additional marketing to be sold.
The fuel sales are effectively subsidizing the cost of plastic, as it would not be cost effective to produce on its own. Other, cheaper, and easier to manufacture materials would displace its uses if it wasn’t already being produced as a byproduct of fuel.
So plastic use is standing on the shoulders of fuel production. Interesting to imagine what materials could emerge as the next default when the prices are not offset by waste disposal needs.

Thank you for clarifying!
