Black mass – bright future
At our battery recycling facility in Halmstad, we have now produced our first-ever black mass – a crucial step on the path towards sustainable battery production.
What is black mass?
Black mass can be found in lithium-ion batteries and is a mixture of valuable metals such as lithium, manganese, cobalt, and nickel.
Why produce it?
Lithium-ion batteries are the backbone of modern electric vehicles, but producing them often involves environmentally harmful practices. Our black mass is a potential game-changer for the electromobility industry.
Being able to produce black mass means that we can now recycle the entire battery. This minimizes the carbon footprint and labor compared to traditional mining for battery materials, making it the sustainable choice.
What’s the next step?
The goal is ambitious – to recycle 10,000 tons of batteries annually, with a substantial portion of the black mass to be refined and reused in new batteries.
As global directives like the 2026 Battery Directive emphasize the recycling of battery materials, producing black mass will become increasingly important.
A unique process
“I am extremely proud of the amazing team I work with and the dedication and drive that exists within our workgroup. It's great people like my colleagues who make this possible. I'm also proud that we are the first facility within Stena to work with lithium-ion batteries. We have an amazing new facility in Halmstad and a unique process that makes our battery recycling very efficient.”
