Best way to up plastic production on vulcanus

[nsdemon]

So I noticed that the liquids that are used in plastic production take awhile to be made and I've tried adding speed and production mods to the chemical plants to boost plastic production
Other than adding more plants and lines bringing in coal
What else can I do this seems like it's really slow

Also I'm not using any quality items I'm just not setup for it yet

Beacons? Even more chemical plants?

If you are using chemical plants, i suppose it's because you are still in early game, as for plastic , one could use some other buildings later.

There is also a research increasing plastic productivity, which would allow to make increasingly more plastic from the same amount of fluid.
