Electric vehicle battery manufacturer Northvolt, and leading metal recycler EMR have built and commenced operations at a battery recycling facility in Hamburg. The brand new site will recycle the huge number of electric vehicle (EV) batteries that will reach their end of life in the years ahead and provide much-needed capacity to support the recycling of batteries in Europe.
The new facility will play a crucial role in dismantling these complex batteries before material is sent on for further processing or re-enters the circular supply chain.
The facility, operated and furbished by EMR, features equipment enabling the discharge and dismantling of approximately 10,000 tonnes of electric vehicle battery packs per year. This will provide crucial recycling capacity as millions of drivers switch to electric vehicles. The layout and process flow of the facility was undertaken by Northvolt, integrating battery discharging and dismantling solutions designed and delivered by the company.
The discharge and dismantling of the battery packs is the first step in the battery recycling process. With more than 70 years of experience in the metal recycling industry, EMR will use its expertise to safeguard the high-quality copper and aluminum used to build modern EV battery frames. The process will ensure this material can, once again, be used to manufacture sustainable technologies, such as the next generation of electrical vehicles.
Following this, the remaining battery modules recovered from packs at the plant will be delivered to Northvolt’s facilities for further recycling. There, the modules will be crushed to enable the recovery of plastics, aluminum and copper. The remaining material, known as black mass, will be processed at Revolt Ett recycling plant in northern Sweden using Northvolt hydromet technology to recover battery-grade materials including more lithium, nickel, manganese, and cobalt.
These materials will be fed to Northvolt’s adjacent cathode active material production facilities, which in turn support on-site battery manufacturing. When fully built, Revolt Ett will enable the processing of 125,000 tonnes of black mass per year – sufficient to cover approximately half of Northvolt Ett’s raw material needs for cathode production.
At every stage, the material that EMR and Northvolt recycle creates an entirely new pathway to sourcing minerals required for battery manufacturing – one that is economically and environmentally preferable to mining.
Now in operation, the Hamburg facility is receiving battery packs and modules from the European electric vehicle market, secured by Northvolt. Alongside end-of-life battery packs of varying designs, the facility is also equipped to receive and process battery packs that are recalled from the market.
With these capabilities, the facility represents a key piece of infrastructure within Northvolt’s offer to its automotive customers, as well as to other stakeholders requiring battery recycling solutions.
