Hazardous solid waste encapsulation units

A brief overview of the process

The waste stabilisation principle is based on a heterogeneous assembly of agglomerated waste using a hydraulic binder.

The hazardous waste is conditioned by compacting and then placed into a package (drums: plastic, metal and concrete) or deposited into stabilisation cells. A concrete block confines the waste in the package; after a period of drying, a biological seal completes the package.

Syneox innovation

This method enables the coating of incinerated waste such as clinkers ashes, smelter dust and aggregates. The coating is produced from waste, a binder (Portland or alumina), water and chemical additives.

The advantages

  • Compression resistance (10 to 60 MPa)
  • Full automation of the process
  • Monitoring via a touch tablet
  • Traceability of information and events on a database
