If we could turn plastic straight into diesel fuel. The amount of fuel would not drive the truck back to the plastic recycling plant. Plastic recycling is a myth.
(unless you are extruding YOUR used plastic into filament to be used in YOUR 3D printer.)
We should be burning all of this in high temperature, vortex reburning power plants.
Turning that waste into electricity at the source of the waste.
Recycling is pretty much a myth to keep people complacent and consuming, without guilt.
