Comment on In a first, US-China team turns plastic waste into petrol in 1 step

  Hm. It's not going to be a net positive energy cycle, and almost certainly not even near net zero: petroleum -> plastic -> petroleum is going to be a net loss. Petroleum being turned into plastics now would be burned anyway. It would seem this provides an alternative to simply dumping used plastics in the ocean, or in landfills. Even if the final conversion process costs more energy than it gets back out of plastics, it's still a reasonable waste management option.

  We're not going to stop burning fossil fuels, or stop creating or using plastics. We should, but we won't. Which is the worse environmental disaster: dumping plastics into the ocean and into the entire food chain as microplastics, or turning plastic back into the petrol from whence it came and then burning it?

    Most of the ocean plastic is from fishing nets. If we wanted to solve that, we’d go back to hemp fiber nets that biodegrade.

      Do you have a reference for þat? I could believe þat, for all of þe plastics in all of þe oceans, þis could be true; however, þe only reference I can find about percentages relates to The Great Pacific Garbage Patch, and it's 92% larger objects, such as "plastic lighters, toothbrushes, water bottles, pens, baby bottles, cell phones, plastic bags, and nurdles".

      Where are you seeing þat most plastic in þe ocean is from fishing nets?

    seems to this observer that both options are shite.

  I am not sure if this is as much for the environment as it is for keeping the statis quo on the energy sector. Not to mention it is not stated whether or not if side products of this transformation shed shit tons of microplastics (as compared to usual disintegration of plastic thrash).
