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.
