Europe imports all of its antimony
We produce it from waste
A critical raw material, essential to safety, to defence and to our digital and energy transition.
We extract antimony from everyday plastic waste that is burned today, such as the plastics of electronic equipment.
Europe burns a strategic resource it needs
DeeeMines recovers it
This critical metal goes into batteries, cables, touchscreens, solar panels and ammunition.
At end of life, with no recycling route, these products go to the incinerator along with the antimony they contain.
All the antimony used in the European Union comes from outside it.
China, Russia and Tajikistan account for most of world production.
Lasting pressure on a metal the European Union lists as critical.
Antimony from batteries is already recycled. Antimony from plastics is incinerated.
We bring three raw materials back to life, out of waste
We take from sorting centres the antimony-bearing fraction they incinerate for lack of any way to recover it, and we extract three resources from it.
European antimony
Recovered as trioxide or as metal, to the buyer's specification. A traceable material at a stable price, produced in Europe.
Flame retardants isolated instead of burned
The brominated molecules come out intact and separated from the polymer. Those that are persistent organic pollutants need to be transformed before any reuse.
A plastic freed of its additives, recyclable again
A stream whose only destination was the incinerator becomes a usable material again.
Separate,
without destroying
The process was developed at the Institut de Recherche de Chimie Paris, with the three researchers who co-invented it.
No other technology can recover the antimony contained in plastics today.
Shredding
Brominated, antimony-bearing plastics from electronic equipment are reduced to a uniform fraction.
Dissolution
The polymer is dissolved, which opens access to the additives trapped in the matrix.
Selective extraction
Antimony is extracted first, then the brominated molecules. Each family is isolated in its own phase.
Precipitation
The cleaned polymer is recovered as a solid, and the solvents go back into the next cycle.
