MIDAR Technology

MIDAR is a revolutionary sustainable geopolymer technology that can be used for numerous applications, such as encapsulating nuclear waste.

What is MIDAR?

A technology platform that uses a low temperature chemical reaction to consolidate aluminosilicate materials and form a robust solid inorganic material with high strength and chemical stability.  The resulting material can be used as an encapsulation and immobilization agent by incorporating a solid or liquid waste stream into the inorganic solid matrix that is formed during the reaction.

The MIDAR geopolymerization process can be varied to accommodate different methods of forming: extrusion, moulding & casting.

The dominant raw materials are aluminosilicate materials.  Examples include:

  • Coal fly ash
  • Blast furnace slags
  • Perlite
  • Waste glass
  • Construction waste, e.g. bricks & concrete
  • Mine tailings
  • Amorphous clays, such as meta-kaolin
  • Volcanic ash.

Why use MIDAR?

  • Potential to utilize waste raw materials to form a high strength, solid matrix similar to ceramics
  • As the technology is based on a chemical reaction, no firing is required. This reduces energy usage and carbon emissions
  • The resulting material is fire, frost, chemical, shock, water and heat resistant
  • It has a low level of leachability of encapsulated materials (e.g. radioactive substances)
  • Curing time can be altered to suit system needs
  • The resulting solid has negligible shrinkage (near net shape)
  • It is a technology that has been honed by an experienced team of scientists and engineers whose aim is to produce materials technologies that address your technical challenges and commercial needs.
