Right beside the Tesla batteries

Took about 6 q-tips to clean my ears and nose at the end of the day. I've also worked at a couple of gold mines. If you want to hear about some scary chemicals in industry, do a little reading about how gold ore is extracted from dirt. Where is the public outcry for those companies to clean up their slurry piles? I think the power plants are just an easy target

We looked at that, dedicating a cell to nothing but fly ash. The profit would have been less than half of the MSW rate for a more desirable material, but even at that cost the power plants came out cheaper building their own cells. You can't really mix it with sludge during the lower stages of a cell because, like fedup said, it makes an impermeable barrier. It turns to concrete and won't let leachate go to the bottom of the landfill, it pushes it out the sides. I know of one landfill in particular that had to go back with a rock hammer on a trackhoe just to bust through it to relieve the pressure. It would be good on a cap, but caps are a short term project once every few years, and fly ash is constant
