Our differences

We cultivate our difference by transforming waste into raw materials, combining environmental and economic performance to offer a virtuous model.

Green hydrometallurgy technology for the circular economy

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.

Performance

By combining environmental and economic performance, our technology enables batteries to be recycled in a virtuous way, while actively supporting the energy transition.

Our advantages

No acid

Operation in a basic environment using ammonia, eliminating harmful inputs for reprocessing.

No waste generated
(to be reprocessed on site)

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.

No sulfate

Production of carbonates instead of sulfates, eliminating the environmental and industrial constraints associated with sulfate products.

Amino regeneration

Our amines are regenerated and reused for continuous metal extraction.

Energy efficiency

Low input consumption, reducing environmental impact and costs.

Metal salt carbonates
for battery production

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:
