Almost all lead is recycled, among the only elements on the periodic table to earn that distinction. With good reason, mind you: the soft metal is a potent neurotoxic known to impact children’s brain development, among other nasty health effects. Today, nearly all lead is used in batteries (though it was once put into gasoline, leading to widespread contamination, and, in places like Afghanistan, still is.) Most of this dangerous element is now endlessly cycled from battery to battery, thanks to stringent regulations (though enough of it ends up being improperly recycled to constitute one of the world’s worst pollution problems.)
In principle, all metals are infinitely recycleable and could exist in a closed loop system, note the authors of a survey of the metals recycling field published in Science on August 10. There’s a benefit too, because recycling is typically more energy-efficient than mining and refining raw ore for virgin materials. Estimates vary but mining and refining can require as much as 20 times the amount of energy as recycling a given material. Think about it: a vast amount of energy, technology, human labor and time are expended to get various elements out of the ground—and then that element is often discarded after a single use.

One day hopefully we can mine all the land fills for raw materials. I wonder why this hasn't been expioted yet.
I'm sure thiers money in it some how. The amount of metals and chemicals that could seperated in all the land fills in the U.S. alone could be worth 100's of billions.
