In Germany, the Munich-based startup Tozero, which focuses on recycling lithium-ion batteries, has put its first hydrometallurgical pilot plant into operation in Karlsfeld close to Munich. Its building was financed partly by a pre-seed spherical from final 12 months.
In accordance with Tozero, which was based in mid-2022, the pilot plant options large-scale technical gear and helps the startup’s proprietary hydrometallurgical recycling expertise.
A few 12 months in the past, Tozero raised €3.5 million in its pre-seed spherical, which it mentioned was primarily supposed to finance the plant close to Munich. The startup’s backers embody former VW government Jochem Heizmann. In Tozero promotional movies, a consultant from MAN Truck and Bus converse extremely of the startup.
On the finish of July this 12 months, Germany-based Bethmann Financial institution mentioned, of their on-line publication Tenor (in German), “Though the start-up is only a 12 months previous, it reached a milestone a couple of weeks in the past: in keeping with the corporate, the method not solely works within the lab, however the founders have already carried out their concept on a bigger scale.”
Secret restoration processes
Tozero continues to not disclose particulars about its expertise. In an emailed assertion we obtained, it merely says the method “permits the sustainable restoration of all vital battery supplies equivalent to lithium, graphite, nickel, cobalt and manganese.”
Tozero will probably be doing what different battery recycling corporations do: they work with corporations that discharge the batteries and take aside the casing, shredding the content material to kind a black powder. This may be separated into recoverable vital supplies talked about above with the assistance of sieves, magnets and chemical processes. Whereas the method of manufacturing black mass shouldn’t be new, Tozero has developed a novel chemical strategy of part separation that’s attracting the eye of the nascent German and European battery industries.
Now, with the brand new pilot plant, Tozero says it may possibly already meet the EU’s minimal lithium restoration fee necessities of 80 per cent from 2031. The form of curiosity the startup is buying and what different recyclers are aiming at would counsel their secret chemical course of can do way more.

Accessible battery recycling materials in Europe
Whereas the processing capability of the brand new plant goes unmentioned, the quantity of batteries in a position to be recycled in Europe will rely on laws, numbers of obtainable electrical car and stationary storage batteries, and the second-life companies and functions in what China calls the “cadence” battery makes use of earlier than recycling. China is additional alongside on this course of, now legislating for “cadence” battery use with many enterprise fashions and processes concerned. Tozero founders spotlight their objective to make sure “the countless life” of batteries.
In June this 12 months, the EU Parliament adopted new guidelines for the design, manufacture and recycling of all forms of batteries bought within the EU. Battery producers will thus be topic to stricter environmental and due diligence necessities in the event that they need to promote on the European market.
The curiosity in collaborations with battery recyclers in Europe, equivalent to Tozero, consists of battery makers, electrical car producers – which in Germany, now consists of a number of the worlds largest automotive gamers, digital waste recyclers, and second-life battery companies, equivalent to their fellow German battery circularity companies, Voltfang (second-life batteries for stationary storage), or Volytica Diagnostics (expertise to evaluate the life-cycle section of a battery to find out the optimum time to maneuver the supplies onto the following section of second or third-life functions and recycling).
Huge ambitions, nice begin
On LinkedIn only a week in the past, the Tozero founders mentioned that in 5 years, they need to be one of many main battery recyclers worldwide.
Earlier than founding Tozero, Dr. Ksenija Milicevic Neumann labored as a Senior Researcher at IME Course of Metallurgy and Steel Recycling Institute on Battery Recycling, Area Assets and Zero-emission Metallurgy. Tozero is technically suggested by Bernd Friedrich, head of the Institute for Course of Metallurgy and Steel Recycling (IME) at RWTH Aachen College.
Dr. Neumann’s Co-founder is Sarah Fleischer, a graduate of Havard Enterprise College and Columbia Enterprise College within the US, her earlier expertise consists of being a visiting fellow for innovation in science at Harvard, and an financial advisor to the Luxembourg Area Company.
Now, opening the pilot plant, shrouded in relative secrecy, Fleischer says: “Along with our clients, suppliers and buyers, Tozero is on the forefront of the electrification revolution in Europe. The newly opened pilot plant is a vital milestone in our mission to really deliver lithium-ion battery waste to zero”.
