Treating asbestos at 1,100 °C instead of 2,200 °C.

Asbestos treatment is the first process we are taking to national scale. It rests on research carried out in France by our founder and secured by a granted patent.

The technology relies on high-frequency coupling. It works at a markedly lower temperature than conventional vitrification: around 1,100 °C, against roughly 2,200 °C for a plasma torch. Less energy consumed, for the same result: a vitrified, inert material that can be handled safely.

Process developed and patented by F. Tedjar — patent FR 266062A1.

  1. Asbestos fibres before treatment 01

    The asbestos waste

    Fibres collected and packaged before treatment.

  2. Crucible at high temperature during melting 02

    High-frequency melting

    High-frequency coupling brings the material to around 1,100 °C.

  3. Molten material being poured in the workshop 03

    Pouring

    The molten material is poured, then cooled under controlled conditions.

  4. Blocks of vitrified material obtained after treatment 04

    Vitrified material

    An inert, stable glass that no longer releases fibres.

Test site · Laghouat

The trials have begun, in Algeria.

Trials have been started locally, at our Laghouat site, and the first results are encouraging. This is the stage that prepares the move to a national treatment capacity.

The processes developed by our founder

The urban mining concept was built on twenty years of applied work. These processes form the technical foundation of the technology transfers we are preparing in Algeria.

  • Primary recycling of cells and batteriesTechnology developed at the University of Grenoble, patent FR 9845467, commercialised in France, Spain, the United States, Italy, England, Singapore and China.
  • Electric arc furnace steel dustRecovery of the metal fractions contained in the dust emitted by steelworks.
  • Incineration bottom ash and fly ashTreatment of the solid residues from waste incineration.
  • Thermochemical conversion of asbestosVitrification by high-frequency coupling, at reduced temperature.
  • Electrical waste and screensTreatment of end-of-life electrical equipment, screens included.
  • Lithium batteries from electric vehiclesThe most recent work, at the heart of the strategic metals question.
