Electric vehicles (EVs) are generally more eco-friendly than traditional cars, but they still present environmental challenges, particularly in battery production. Innovations in battery recycling, including new facilities and materials like sodium batteries, show promise. By 2030, recycled lithium could power over 2 million EVs in Europe, addressing some material needs and potentially preventing the need for new mines. However, many recycling projects face significant obstacles, with only a small percentage currently operational.
The Environmental Impact of Electric Cars
It’s widely recognized that electric vehicles (EVs) are more environmentally friendly compared to traditional combustion engine cars. This fact has been substantiated through extensive research. However, we must acknowledge that electric cars are not entirely free from environmental concerns, and the journey towards achieving 100% cleanliness and zero emissions is still ongoing.
Advancements in Battery Recycling
One of the primary criticisms aimed at electric cars revolves around the environmental toll of battery production, particularly the extraction of materials like lithium and rare earth elements, which often occurs under questionable ethical and ecological standards. Fortunately, there are positive developments on the horizon. Innovations such as sodium batteries and enhanced recycling methods are gaining traction.
Leading manufacturers and suppliers are increasingly focusing on battery recycling solutions. For instance, Mercedes has recently launched a dedicated recycling facility, though it admits that this approach is not a panacea. The NGO Transport & Environment (T&E) has investigated this issue and presented promising statistics in its recent report.
T&E estimates that by 2030, recycled lithium could power over two million electric vehicles in Europe. While this number is impressive, it still falls short of the projected 9.6 million electric vehicle registrations in the region by that time. Nevertheless, recycling is projected to fulfill about 15% of lithium requirements and contribute significantly to other essential materials: 13% of manganese, 25% of nickel, and 62% of cobalt needs for electric vehicles. As time progresses, these contributions are expected to grow. By 2040, zero-emission vehicle sales could hit 16.3 million, with lithium recycling potentially supporting 5.2 million of those vehicles, alongside 15.4 million for cobalt and 7.6 million for nickel.
Moreover, T&E highlights that the growth of the battery recycling industry in Europe could prevent the establishment of 12 new mines worldwide by 2040, which is a substantial step towards sustainability. This progress will not only make electric vehicles cleaner but will also reduce reliance on China for raw materials.
Additionally, the carbon footprint could be reduced by nearly 19% if lithium is recycled within Europe rather than being mined in Australia and processed in China, as is often the case currently. However, challenges remain. The development of recycling facilities is encountering significant hurdles, with nearly half of the proposed projects facing threats of cancellation.
Currently, only 8% of recycling plants are operational, 4% are under construction, while 22% are on hold and another 22% are at high risk of being scrapped. For example, the Parkes project in Carling-Saint-Avold, Moselle, has been stalled. Yet, there is hope with initiatives like the Norwegian company Hydrovolt’s new battery recovery site in France, which is set to open next year, and BMW’s upcoming factory in Germany that will employ a “direct recycling” approach.
