The European Union has implemented new regulations mandating the recycling of electric vehicle batteries, marking a key step in the bloc's approach to sustainability and resource sovereignty. These rules apply to batteries used in electric cars, bicycles, and scooters, aiming to enhance the recovery and reuse of valuable materials from used batteries. The regulation is framed as an issue of sovereignty for the EU, emphasizing the importance of managing battery lifecycle within Europe. In parallel, industry efforts are underway to extend the life of used electric vehicle batteries, as exemplified by a German company repurposing these batteries for secondary uses. However, challenges remain, highlighted by a recent fire incident at Tesla's German factory in the battery pack area, which led to a partial evacuation. Overall, the EU's new battery recycling rules represent a strategic move to boost sustainability and resource efficiency in the rapidly growing electric mobility sector.
