In the EV era, “urban mining” means getting valuable metals not from the ground, but from used batteries, old electronics, and factory scrap that are already inside our cities and supply chains. This idea is becoming more important because battery demand is rising quickly. The IEA says EV battery demand could reach more than 3 TWh by 2030, and the European Commission says global battery demand may grow 14 times by 2030. In other words, yesterday’s batteries are starting to look like tomorrow’s mines. (iea.org)
Governments are now turning that idea into real rules. In the EU, the new Batteries Regulation entered into force on August 17, 2023, and it is designed to make batteries more circular from production to recycling. From February 18, 2027, EV batteries sold in the EU must have a digital battery passport. The rules also set targets for recovering lithium from waste batteries: 50% by 2027 and 80% by 2031. From 2031, new EV batteries will also need minimum levels of recycled material, including 16% cobalt and 6% each for lithium and nickel. In 2025, the Commission added detailed rules for how recycling efficiency and material recovery should be measured and verified. (environment.ec.europa.eu)
Companies are racing to become leaders in this new business. In the United States, Redwood Materials says it now recovers more than 20 GWh of lithium-ion batteries each year and produces over 60,000 tons of critical materials annually. In China, CATL reported that its spent-battery recycling volume reached 210,000 tonnes in 2025, up 63.2% from the year before. The competition is also visible in technology: on April 29, 2026, the IEA and the European Patent Office said that patenting in battery circularity is growing even faster than battery patenting in general, with Asia leading the field.

Still, recycling is not a magic answer yet. The IEA warns that because the supply of old batteries is still limited, recycling will need about a decade before it makes a major cut in demand for newly mined minerals. Even so, the environmental benefits are impressive. Stanford researchers found that recycling lithium-ion batteries can create less than half the greenhouse gas emissions of conventional mining and use about one-fourth of the water and energy. That is why the battery recycling race matters so much: it is not only about waste, but about who can build the cleanest and smartest resource system for the EV age. (iea.org)
