Green360’s MKX Gains Traction Across Major Melbourne Infrastructure Projects

MKX Passes 3,500m³ Commercial Use Milestone

Green360 Technologies Limited (ASX:GT3) has moved its MKX calcined-clay product further into the construction mainstream, with more than 3,500m³ of concrete containing MKX now placed across major Melbourne infrastructure and civil projects. The volume is equivalent to more than 500 concrete truckloads, according to the company.

The material has been purchased and used in commercial pours by concrete suppliers including Holcim Australia, which Green360 identifies as its first commercial customer, and Eifers. Applications include work connected with the Suburban Rail Loop, the Eastern Freeway Extension and other metropolitan Melbourne civil programs. A further pour is scheduled for taxiway pavement at Melbourne Airport this week and next.

Infrastructure Projects Build MKX’s Operating Record

For Green360, the significance of the milestone lies less in the concrete volume itself than in the range of participants now handling the product. The company says repeated use gives customers, engineers, contractors and infrastructure owners the chance to assess MKX in live conditions, while building experience around applications, specifications and logistics.

That is a more useful test than laboratory validation alone, although the announcement does not disclose MKX sales revenue, pricing, margins or the product volume purchased by each customer. Nor does it provide binding contract values or confirm when a dedicated production facility might be funded or built.

Calix Capacity Delays Dedicated Production Decision

Green360 is pursuing a deliberately staged commercialisation plan. Kaolin from its Pittong operations is currently calcined at Calix Limited’s Bacchus Marsh facility, giving the company access to up to 30,000 tonnes per annum of capacity near the Melbourne concrete market.

That arrangement allows Green360 to develop customer relationships and demand before investing in substantially larger dedicated production capacity. The company says it intends to increase commercial volumes through this existing platform, using real-world adoption to establish the requirements for any later scale-up.

SCM Shortages Create a Larger Addressable Problem

MKX is being positioned as an alternative to traditional supplementary cementitious materials such as fly ash and blast furnace slag. Green360 says the availability of those materials is expected to tighten as coal-fired power stations close and steelmaking shifts towards newer technologies, prompting concrete and infrastructure users to consider other sources.

MKX can replace up to 40% of Portland cement in concrete, the company says, but the strategic opportunity remains dependent on converting project exposure into recurring orders and proving that supply can scale economically. The next practical markers are the Melbourne Airport pour, repeat purchasing by established suppliers and any decision on dedicated manufacturing capacity.
