Which would be best achieved by leaving that CO2 locked up in plastic in the landfill, not to convert the plastic back into fuel to be burnt.

Agree with your first assesment - e-fuels are pushed by big oil to keep the status quo up as long as possible.

Disagreeing on the last technicality though: leaving stuff on landfills tends to leak methane into the athmosphere, which sucks.

For food waste we should replace compost and landfills with biodigesters, so that the methane gets captured, burned for energy and thus gets double use and lower impact (if done enough it can replace a big part of nat gas consumption)

If they manage to digest plastic into something useful too, why not. But Unfortunately good things like these will be used to keep producing plastic, which is an entire problem in itself.

Plastic will not decompose to methane. And the reason not to convert it to something else is that that process will release its embedded co2 into the atmosphere.

Yes, the methane comed mostly from bio stuff. But plastic will degrade into smaller plastic, eventually getting into our drinking water. Already they found microplastics in the human bloodstream. We really need to get away from single use platics, plastic clothing and plastic fishing nets.
