A $60 Billion-a-Year Climate Solution Is Sitting in Our Junk Drawers – Mother Jones

...

Only 22 percent of that e-waste is collected and recycled, the UN estimates. The rest is dumped, burned, or forgotten—particularly in rich countries, where most people have no convenient way to get rid of their old Samsung Galaxy phones, Xbox controllers, and myriad other gadgets. Indeed, every year, humanity is wasting more than $60 billion worth of so-called critical metals—the ones we need not only for electronics, but also for the hardware of renewable energy, from electric vehicle (EV) batteries to wind turbines.

Millions of Americans, like me, spend their workdays on pursuits that lack any physical manifestation beyond the occasional hard-copy book or memo or report. It’s easy to forget that all these livelihoods rely on machines. And that those machines rely on metals torn from the Earth.

Consider your smartphone. Depending on the model, it can contain up to two-thirds of the elements in the periodic table, including dozens of metals. Some are familiar, like the gold and tin in its circuitry and the nickel in its microphone. Others less so: Tiny flecks of indium make the screen sensitive to the touch of a finger. Europium enhances the colors. Neodymium, dysprosium, and terbium are used to build the tiny mechanism that makes your phone vibrate.

Your phone’s battery contains cobalt, lithium, and nickel. Ditto the ones that power your rechargeable drill, Roomba, and electric toothbrush—not to mention our latest modes of transportation, ranging from plug-in scooters and e-bikes to EVs. A Tesla Model S has as much lithium as up to 10,000 smartphones.

...

In all of human history, we have extracted some 700 million tons of copper from the Earth. To meet our clean energy goals, we’ll have to mine as much again in 20-odd years. By 2050, the International Energy Agency estimates, global demand for cobalt for EVs alone will soar to five times what it was in 2022. Demand for nickel will be 10 times higher. Lithium, 15 times. “The prospect of a rapid increase in demand for critical minerals—well above anything seen previously in most cases—raises huge questions about the availability and reliability of supply,” the agency warns.

...

The harm is staggering. Metal mining is America’s leading toxic polluter. It has sullied the watersheds of almost half of the rivers in the American West. Chemical leaks and mining runoff foul air and water. The mines also generate mountains of hazardous waste, stored behind dams that have a terrifying tendency to fail. Torrents of poisonous sludge pouring through collapsed tailings dams have contaminated waterways in Brazil, Canada, and elsewhere and killed hundreds of people—in addition to the hundreds, possibly thousands, of miners who die in workplace accidents each year.

To get what they’re after, mining companies devour natural resources on an epic scale. They dig up some 250 tons of ore and waste rock to get just 1 ton of nickel. For copper, the ratio is double that. Just to obtain the metals inside your 4.5-ounce iPhone, 75 pounds of ore had to be pulled up, crushed, and smelted, releasing up to 100 pounds of carbon dioxide. Mining firms also suck up massive quantities of water and deploy fleets of drill rigs, trucks, diggers, and other heavy machinery that collectively belch out up to 7 percent of the world’s greenhouse gas emissions.

These operations are not popular with the neighbors. Irate locals and Indigenous communities at this moment are fighting proposed critical-metal mines across the United States, in addition to Brazil, Canada, the Philippines, Serbia, and many other countries. At least 320 anti-mining activists have been killed worldwide since 2012—and they are just the ones we know about.

...

Spent lithium batteries present their own recycling challenge. They are potentially among the world’s best sources for critical metals—one study found that battery recycling theoretically could satisfy nearly half of global demand for certain metals. Yet only about 5 percent of them get recycled because they are uniquely hard to handle—and dangerous.

Nigeria, for example, is awash in lithium-ion batteries, but no place on the continent recycles them. They need to be exported. Shippers don’t want to take them, however, because of their disturbing tendency to burst into flames when punctured, crushed, or overheated. Battery fires can exceed 1,000 degrees Fahrenheit. They also emit toxic gases and are very hard to extinguish. American consumers are asked to bring unwanted lithium batteries to a domestic recycler or a hazardous waste site, and for good reason. Every year, batteries from everything from old Priuses to sex toys cause hundreds of fires in US scrapyards, landfills, and even on garbage trucks, causing millions of dollars in damage. Residents of Fredericktown, Missouri, even had to evacuate their homes earlier this month when a local battery recycling facility exploded dramatically into flames.
