Green360 Completes First Commercial Eco-Clay Production, Eyes 1H 2026 Market Launch

First Commercial Production Marks Key Milestone

Green360 Technologies (ASX:GT3) has completed the first continuous commercial production run of its Eco-Clay low-carbon cement replacement, delivering 150 tonnes under a toll treatment agreement with Calix Limited (ASX:CXL). This production run is a significant step beyond pilot stages, demonstrating the company’s ability to manufacture Eco-Clay at a scale relevant for industry adoption.

Eco-Clay, a calcined kaolin-based material, can replace up to 40% of traditional Portland cement in concrete, offering a substantial reduction in carbon emissions. The product is manufactured from Green360’s own kaolin by-products, transforming industrial tailings into a high-reactivity metakaolin through calcination at approximately 750 degrees Celsius, a process that consumes considerably less energy than conventional cement production.

Scaling Production via Toll Treatment with Calix

The toll treatment agreement with Calix, announced in March, allocates up to 30,000 tonnes per annum of Calix’s plant capacity to Green360, enabling a capital-light pathway to scale production rapidly. This arrangement allows Green360 to focus on commercialising Eco-Clay without the upfront costs of building its own manufacturing facilities. The company has already produced over 600 tonnes of Eco-Clay, which have been distributed to concrete suppliers in Victoria for customer-led field validation within major infrastructure projects.

Green360 expects to finalise its first commercial supply agreement for Eco-Clay within this quarter, setting the stage for broader market penetration. Executive Chairman Aaron Banks emphasised the importance of this milestone, noting ongoing efforts to improve production efficiencies and expressing confidence in the product’s commercial viability. The company remains on track to commence commercial sales in Victoria during the first half of 2026.

Eco-Clay’s Potential in Decarbonising Construction

Eco-Clay’s ability to reduce concrete’s carbon footprint aligns with growing demand for sustainable building materials amid tightening environmental regulations and industry commitments to net zero. By utilising kaolin tailings and settlement pond residues, Green360’s circular economy approach not only lowers emissions but also diverts waste from landfills.

This development follows Green360’s recent binding toll treatment agreement, which laid the groundwork for scaling production. It also complements earlier capital raises and federal grants that have underpinned the company’s commercialisation strategy. However, the company has yet to disclose pricing details or the exact terms of upcoming supply contracts, leaving some uncertainty around near-term revenue generation.
