Our efficient and low-CO2 battery recycling processes combine mechanical and hydrometallurgical recycling technologies. The technology was developed by Fortum, and the battery treatment processes have been optimised for high safety, sustainability, and a high recovery rate.
Lithium-ion Battery Recycling Technology
We use a combination of mechanical and hydrometallurgical technologies to recycle the battery materials. Our industrial-scale, low-CO2 processes allow us to recover lithium, cobalt, manganese and nickel from the battery for reuse in the production of new batteries. Our optimised battery treatment processes are safe, sustainable, and efficient.
The lithium-ion batteries are first disassembled and treated during a mechanical process at Fortum’s plant in Ikaalinen, Finland. The mechanical processing enables us to recover plastics, aluminium, copper, and black mass. The battery’s black mass, containing critical metals, is collected and then taken for hydrometallurgical processing at Fortum's plant in Harjavalta, Finland. Other recovered materials are recycled in separate processes.
The hydrometallurgical recycling process involves a chemical precipitation methodology that allows scarce minerals to be recovered from the black mass and delivered to battery manufacturers for reuse in the production of new batteries. We are continuously looking into different ways and processes to extract a higher yield and higher purity from the battery materials.
Our low CO2 battery recycling process
Hydrometallurgical recycling facility
We are building a new,state-of-the-art hydrometallurgical plant in Harjavalta, Finland. The new plant will enable us to expand our recycling capacity of lithium-ion batteries and the production of sustainable battery chemicals. The new Harjavalta facility will help to meet the rising demand for recycled battery materials and enable the sustainable recovery of lithium, nickel, cobalt, and manganese, all of which are essential in the manufacturing of new EV batteries.
