Circular recycling is going to upgrade the EV industry.♻️
"Ford sent us 10 pounds of mixed plastic waste from a vehicle shredding facility," said Tour, in an embargoed release shared with."We flashed it, we sent the graphene back to Ford, they put it into new foam composites and it did everything it was supposed to do.""Then they sent us the new composites and we flashed those and turned them back into graphene," added Tour."It's a great example of circular recycling.
But separating the different kinds of plastic in cars at the end of their life for recycling has remained a problem for a long time, said Tour. And this problem is all the more acutely felt because of upcoming surrounding end-of-life vehicles."In Europe, cars come back to the manufacturer, which is allowed to landfill only 5 percent of a vehicle.""That means they must recycle 95 percent, and it's just overwhelming to them," added Tour. Flash Joule heating, the method used to recycle graphene, was first introduced by
in 2020. It places mixed ground plastic and a coke additive between electrodes inside a tube. Then this is placed high voltage.— and that's simple for scientists to solubilize. This flash heating process also provides benefits for the environment, since it doesn't take solvents, and only uses a comparably small amount of energy to generate viable graphene.
Rice lab tested its process by grounding Ford's waste"fluff" — consisting of plastic bumpers, carpets, gaskets, mats, and seating and door casings from expiredThe first process left highly carbonized plastic that was roughly 30 percent of the initial bulk . Then the high-current flashing converted the carbonized plastic into graphene, which had 85 percent of the second bulk. Doing the multiplication, that leaves 25.5 percent of the initial bulk from Ford successfully recycled.
