Engineering encapsulation processes

Expert in the encapsulation treatment of hazardous solid waste, Syneox offers a comprehensive range of innovative solutions for the implementation of ceramic or Portland based cementation.

Syneox carries out packaging processes resulting in the safety of the ultimate compound. Its innovations permit long-term encapsulation (sustainability…) of hazardous waste.

Its collaboration with research institutions (CNRS) has ensured the relevance of process engineering.

Several patented processes offer solutions for solid waste such as irradiating waste, asbestos, ash, polluted soil, sludge, slag, clinker, smelter dust …
The waste status is also considered: whole, compacted, crushed …

Treatments offered

Encapsulation by cement packaging

  • Encapsulation or coating in packaging
  • Double encapsulation (packaging and simultaneous encapsulation)
  • Stabilisation by mortar
  • Encapsulation for sanctuarisation (local)
  • Recycling as substructure or stabilising material

The packaging used is: metallic, concrete, ceramic and plastic.

The advantages

Particle capture is possible on solids of 10 nm¯¹ to 10 mm¯¹; coating comprises the body from 10 mm to several tens of centimetres.

Ceramics provide centuries of encapsulation with a duration of over 10 centuries.

Our processes are suited for the encapsulation of radioactive or contaminated waste ranging from Low-level waste (LLW) to Intermediate-level waste (ILW).

Encapsulation by ceramic cementing offers safety and greater biological security, consequently preserving the environment and human biological protection.
