USA exports used solar panels for disposal in trash dumps 'over there'. The entire lifecycle of electric usage is important and easily overlooked.
Be precise with legislation. For example, some States forbid landfill of whole tires. This led to collection of per-tire disposal fee and the landfills purchasing new wheel loader to scoop whole tires into new shredder which uses new conveyor to pile up the tire shreds. Wheel loader then scoops shreds and sprinkles the shreds into landfill.
