| Mar 12, 2021 at 17:57 | comment | added | Kav | Andrew, I think you are suggesting that the cost-effective process -- if exists --- makes S itself valuable than burning S or PS as fuel. Or in other words, the process counters the motives to find a plastic replacement of PS. | |
| Mar 12, 2021 at 17:48 | comment | added | Kav | Well, the directions of ideas shall diverge then. Let us take polystyrene (PS) as an example. Firstly, find an alternative and/or replacement of PS. Secondly, pyrolyze PS to simple hydrocarbons and refine them in similar processes existent in petrochemical industries. Thirdly, potential eight carbons monomer -- styrene (S) -- is made into isooctane (IO) the fuel, instead of polymerization. | |
