TL;DR: Pyrolysis with a yield of 60 percent styrene monomers.
So what does that mean?
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.
Woohoo!
Just outlaw it already. It was a bad idea
But then how will I make homemade napalm?
This is the way to upcycle it
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
Here is an alternative Piped link(s):
Piped is a privacy-respecting open-source alternative frontend to YouTube.
I'm open-source; check me out at GitHub.
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.
How will people convert convenience into money and become rich at the expense of future generations?
10Mj/kg = 2.7kWh/kg
Not bad efficiency.
The problem is how low the density is.
Sure: per kilogram it looks ok, but that one kilogram took up an entire train car to move around.
And imagine being the guy who's got to clean out the train car afterwards of all the tiny pieces. Nightmare fuel.
Oh my God my wife bought this bean bag once. It was a photography thing so it had to be absolutely packed full. So the skin came folded up in this tiny little plastic bag and then it came with three giant bags of styrofoam balls.
If you stuck your hand in the back and pulled it out it would just be coated. I spent hours just trying to scoop them into the bean bag.
When I got to the second bag to fill I found a long narrow box and taped it up to the side of the bean bag slice the bean bag open and used it to pour them through.
The whole experience was awful. And the cleanup took nearly as long as the fill.
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.
