Australia’s electric vehicle fleet has quietly reached a milestone: more than 100,000 units now traverse its roads. Yet behind the progress toward lower carbon emissions lies a rapidly approaching challenge—what to do with the vast number of lithium-ion batteries that will eventually reach the end of their service life. Research from the University of Technology Sydney (UTS) projects that by 2030, the nation will need to manage approximately 30,000 tonnes of retired EV batteries. By 2040, that figure could rise to 360,000 tonnes, and by 2050, a staggering 1.6 million tonnes.
Experts describe this as a “huge waste stream” with a triple threat: fire hazards in landfill, environmental contamination, and health risks from toxic chemical leaching. Libby Chaplin, CEO of the Battery Stewardship Council (BSC), warns, “We need to take action now.” The BSC, a government-backed body tasked with battery waste planning, has documented frequent fires in waste trucks caused by smaller lithium batteries in general waste and recycling streams. “Electric vehicles are just going to take that to another level,” Chaplin said, noting the significant financial and health impacts on communities.
The World Health Organization has long cautioned about the dangers of e-waste, including respiratory issues, infertility, congenital disorders, and cancer linked to toxic exposure. While EV manufacturers typically guarantee batteries for a decade, UTS researchers estimate an average lifespan of 16 years. However, Griffith University’s Professor Rodney Stewart believes this may be optimistic, citing reduced performance over time and potential for early disposal. “Lithium ion battery effectiveness gets reduced over time. It’s definitely an issue that really hasn’t been tested,” Stewart said.
Each EV battery, weighing around half a tonne, contains not only plastics, aluminum, and wiring but also valuable metals such as lithium and copper. These finite resources underscore the importance of recovery and reuse. Some automakers engage recyclers like EcoBatt in Melbourne to process damaged or recalled batteries. EcoBatt’s Hamish Lee describes their custom “explosion box” transport cases, lined with fire-retardant vermiculite and fire blankets, designed to contain any thermal events. Once inside the facility, technicians dismantle the battery’s outer casing, strip metals, plastics, and wiring, and separate the cells. Certain metals can be sold domestically, while cobalt and lithium are sent offshore for processing.
The concept of a circular economy—recycling materials from old batteries into new ones—is gaining traction. Volkswagen and others have expressed interest, though the industry remains in its infancy. “We want to reuse [these batteries] for future generations,” Lee said. The BSC sees circularity as critical, both to avoid unnecessary mining and to preserve finite resources. Chaplin emphasized, “It’s very important that we recover those precious resources. If we’re going to have a renewable future, we need to figure out how to deal with these batteries.”
A 2020 CSIRO report, still considered valid, projected 180,000 tonnes of lithium-ion battery waste by 2036. It identified a potential economic upside: if Australia could recycle and reuse all projected waste, the benefit could reach $30 billion by 2036. The BSC has already implemented a stewardship scheme for small batteries, funded by levies on imports, but scaling such a program for EV batteries presents logistical complexities due to global supply chains and the sheer size of the units.
Chaplin noted, “Obviously, if the industry doesn’t step up, I’ve no doubt that government would regulate in this space—just because of the massive number of batteries that are going to be coming to end of life in the not too distant future.” The Department of Climate Change, Energy, the Environment and Water confirmed ongoing collaboration with industry to reduce waste from all products, including EVs. Its National Battery Strategy, under development by the Department of Industry, Science and Resources, aims to address the full lifecycle of batteries, from production to recycling.
