We are developing a battery waste recycling technology based on innovative hydrometallurgy.
Unlike traditional methods using sulphuric acid, our process operates under basic conditions, using an ammonia-based route.
Using the properties of CO2 as a precipitating agent, we selectively extract all the strategic metals present in batteries.
Carbonates
metals
We produce metal salts in the form of carbonates, which have the same properties as conventional metal salts, but without the sulphates, a problematic component both for the environment and for pCAM and CAM manufacturers.
Performance
This process generates no effluent, making it compact and enabling us to adapt to the quantities of available deposits and to locate as close as possible to waste sources.
Economic performance
By combining environmental performance, our technology enables batteries to be recycled in a virtuous way, while actively supporting the energy transition.
Operation in a basic environment using ammonia, eliminating harmful inputs for reprocessing.
Very little waste is generated, making the plants compact and enabling them to be set up close to the deposits, or even in-situ for gigafactory scraps.
Production of carbonates instead of sulfates, eliminating the environmental and industrial constraints associated with sulfate products.
Our amines are regenerated and reused for continuous metal extraction.
Low input consumption, reducing environmental impact and costs.
The main stages in our process
Thanks to our innovative recycling technology, we produce recycled metal salts in the form of carbonates or hydroxides, with optimum purity for reintegration into the battery value chain and for use by industry.
Here are some examples of the carbonates we produce:
LiC03
Lithium carbonate
Indispensable in the manufacture of Li-ion battery cathodes, our recycled lithium carbonate enables us to reduce dependence on primary resources while maintaining high electrochemical performance.
NiC03
Nickel carbonate
Nickel is a key element in high-energy density batteries. In its carbonate form, it is ready to be converted into a precursor for the manufacture of active materials for new-generation batteries.
MnC03
Manganese carbonate
Used to extend the life and safety of batteries, manganese carbonate from our recycling is easily integrated into industrial processes.
CoC03
Cobalt carbonate
Cobalt is essential for the thermal stability of batteries. Our process extracts a valuable form of cobalt, helping to secure this critical supply.
