"Why are so many companies working on this process
Post# of 43064
I suspect most companies can immediately see that hyrdocarbon-only plastic pyrolysis can never be economically viable so PTOI probably only has very few, if any, 'competitors' trying to pyrolyze those plastics.
For pyrolysis of other materials, people have been trying since at least the mid 1980's and so far nobody has found a way to make money. If I had to guess, I would say that the term "oil" is associated with value even though some oils are worthless. Additionally, some pyrolysis companies like PTOI, SSTP and EFTI are outright scams designed to play on investors' hopes and others like Dynomotive, at least in the past, seemed to be open and honest that they weren't profitable--although they were issued a cease trade order because they stopped publishing financials a few years ago. Others like Agilyx I suspect are a hybrid--investors are willing to pay them to continue to so they don't have any incentive to figure out that they're worthless.
