Calix re-invents the 5,000 year-old kiln

to develop more environmentally friendly solutions for a broad range of industries.

The industries we help

Calix has developed, and is commercialising, a patent-protected technology platform that produces new materials and processes targeted at achieving a better and more sustainable future for all.

Calix’s technology involves grinding minerals to between one hundredth and one thousandth of a millimetre in size, and then “flash” heating them in an externally heated reactor in a very short time, at up to 950 °C.

As trapped gases in the minerals “bubble out” of the particles, they create highly porous structures in the particles. These particles are then cooled very quickly, leaving a very porous, honeycomb-like structure.

Frequently Asked Questions

  • What does “nano-active” mean?

    Research into nano-particles (defined as particles between 1 and 100 nanometers, or billionths of a meter, in size) is rapidly increasing, due to the unique physical and chemical properties these materials manifest, and the potential high value applications in health, electronics, catalysts, 3d printing and batteries.

    However, problems associated with fixing these particles in place to allow practical use, as well as the expense in producing them, has restricted more widespread use.

    Calix’s CFC technology can be used to produce “nano-active” particles…particles which, because of their high surface area, display many of the unique properties of nano-particles, while being a thousand times larger (and therefore more easily and cheaply produced and utilised).

  • What is industrial carbon capture?

    Carbon capture is the process of selectively removing and capturing carbon dioxide (CO2) from industrial processes. It can then be used (eg as an industrial gas, or via technologies under development such as fuel recycling, etc) or permanently stored (eg sequestered in saline aquifers, or via technologies under development such as in building products or plastics).

    Both the cement and lime industries have relatively high CO2 emissions with around 60% of their total CO2 emissions being released directly, and unavoidably, from the processing of limestone (which is 50 % by weight CO2). Carbon capture is the only means by which these industrial processes can dramatically reduce their emissions

  • What is Calix technology used for?

    Calix technology has been successfully scaled to commercial (30kTpa) production, and we are continuing to find new materials and applications with a rich development pipeline.

    New materials produced by our Calix technology are proving to have similar properties to highly active nano-materials, without the safety concerns and high cost, but with all the benefits that nano technology is developing into numerous solutionsapplications and industries.

Solving global challenges

Calix has unique potential to scale solutions to the United Nations’ Sustainable Development Goals. Innovating for the Earth is the very essence of what we do.
