Green360 Technologies Limited (ASX:GT3)'s executive chairman Aaron Banks earlier this week told Proactive it had completed the calcining of over 450 tonnes of high-purity kaolin from its Pittong Operation in Victoria. The processed material will be used to produce high-reactivity metakaolin for incorporation in green cement.
Highlights
- Green360 calcined over 450 tonnes of high-purity kaolin from its Pittong Operation to produce high-reactivity metakaolin.
- The run marks Green360's first commercial-scale production using waste from tailings dams and sediment ponds.
- Material will be used in Victorian government infrastructure projects, allowing both government and industry players to test it.
- The initiative is expected to address consistency issues in Australia’s green cement supply chain.
- Aaron Banks said this milestone could be a "tipping point" in disrupting the concrete industry.
- The company has 140,000 tonnes of available material and expects trial-related sales by year-end.
- Further announcements are due on which government projects the product will be used in — between 5 and 15 are expected.
- Green360 is building familiarity with major commercial players in cement application, such as Boral and Hanson.
First commercial-scale calcining run
For Green360, this was its first commercial-scale calcining run, converting waste from its tailings dams into construction-ready material for large-scale infrastructure projects. Banks highlighted that the demonstration validates the viability of its supply chain and cost structure, which are key to unlocking government and industry uptake.
The processed metakaolin will now be deployed in a range of Victorian government infrastructure developments. Banks said this represents a major step toward commercialisation and positions the company to become a consistent supplier of low-carbon cement inputs in Australia.
Banks said: “We now have product to deliver to government… and visibility on how the supply chain will work, as well as the costs.” He also noted that the company has about 140,000 tonnes of kaolin ready at one tailings dam, with further deposits available.
Sales expected later in the year
The company expects sales from these trials to begin later this year. Banks added that announcements would be made in the coming weeks identifying the specific government projects involved, which could range from five to fifteen.
Banks said the processed material is also being introduced to commercial players that manage concrete delivery on government jobs, enabling wider industry testing and engagement. It flagged that rising costs and limited availability of traditional materials could further enhance the competitiveness of its offering in the near future.
