So what is wrong with this? I am assuming it only takes soft plastic but still why we don't see widespread use of it.

I'm guessing the answer is, "Because you can already burn the plastic directly." Presumably burning this oil would have the same levels of pollution as burning the plastic in the first place, but also takes extra energy to produce.

I think the oil it produced would be worth about £0.25 (GBP) (400ml assuming the price is the same as Brent crude and ignoring the cost of the input plastic or the machine itself etc). But the power to run it (3kWh) would cost about £1 (1GBP) at current rates at least here in the UK.

I might be wrong, I'm not sure whether the oil produced is equivalent to Brent crude (I picked it at random) or more valuable or less...

Still might make sense when solar/wind is at peak to make it as a longer time storage? While still getting rid of plastic waste.

When running on spare hydro, wind or solar power which cannot be accumulated or returned to grid, it can have some uses.

More worth than crude. Crude also needs processing. The output from this bench processor is probably somewhere around the red fraction here:

Other than if you have a Mr Fusion you can’t run a car off of solid plastics. But, I assume some additional steps are required to make it usable. The site doesn’t detail the possible uses of the the oil, but generally liquids and solids can be used in different situations. The oil could also be used as lubricant rather than an energy source.

Also, plastics can contain all sorts of nasty toxic surprises. Better to burn it at a centralized location with proper filtering and treatment than having little batches or mystery oil of varying quality and toxicity.

But of what use is that mystery oil? All current petroluem products are highly quality controlled, both for lubrication and use in engines. You didn't get rid of the plastic, you converted it into a liquid which you must now dispose of safely. The only upside I see is that the plastic won't litter and turn into micro plastics in the ocean, but since it's already collected, then burn in a central plant ASAP IMHO.
