Down on the Farm That Harvests Metal From Plants
“Nickel is a crucial element in stainless steel. Its chemical compounds are increasingly used in batteries for electric vehicles and renewable energies. It is toxic to plants, just as it is to humans in high doses. Where nickel is mined and refined, it destroys land and leaves waste.
In areas where soils are naturally rich in nickel, typically in the tropics and Mediterranean basin, plants have either adapted or died off. In New Caledonia, a New Jersey-size French territory in the South Pacific that has been a major source of nickel, botanists know of at least 65 nickel-loving plants.
Such plants are the most common metal-craving vegetation; others suck up cobalt, zinc and similarly crucial metals. With new electronics spurring surging demand for rare minerals, companies are exploring as far as outer space and the bottom of the ocean. Far less explored is one of humanity’s oldest technologies, the farm.
The language of literature on phytomining, or agromining, hints of a future when plant and machine live together: bio-ore, metal farm, metal crops. “Smelting plants” sounds about as incongruous as carving oxygen.”
