      It’s in more stuff than you think. High density polystyrene is what a good chunk of disposable plastic spoons/forks/knives is made of.

        The clear brittle kind. Cups too, the clear ones that snap when you squeeze them too hard.

      Honestly probably pretty easily. Its not even a good packing material.

    TL;DR: Pyrolysis with a yield of 60 percent styrene monomers.

        ELI5: They can now make the fluffy white plastic go back to liquid very well, and they don’t even need too much work for that.

    Just outlaw it already. It was a bad idea

        I’m very against this unless it’s praxis

    Just mix it with petrol and then you have sticky flammable substance to do with what you will

      Experimenting with spreading mine on a cookie sheet to dry in the sun. Chop it up and you got handy fire starters.

      EDIT: It works perfectly!

    Maybe we could just stop making plastic of all kinds. Reduce Reuse Recycle. Recycling is literally the last resort, we don’t need most of our plastic stuff today.

    10Mj/kg = 2.7kWh/kg

    Not bad efficiency.

      In situ processing should solve that. Imagine a machine where you put that in, it gets crushed and sprayed and the liquid is transported and recycled.

    why is this better than just icinerating it for baseload power? That is the only truly safe way to dispose of plastic, plus pyrolisis adds an extra step, which costs more energy.
