What is the significance of the agreement between Green360 Technologies (ASX:GT3) and Holcim?

Green360 Technologies has secured Holcim (Australia) as the first named commercial customer for its proprietary Eco-Clay product. This is a major validation of the company's low-carbon cement substitute by a subsidiary of one of the world's largest building materials groups.

What exactly is the Eco-Clay product being supplied by Green360 Technologies (ASX:GT3)?

Eco-Clay is a high-reactivity metakaolin designed to serve as a sustainable, low-carbon alternative to traditional cement. By replacing a portion of standard cement in concrete mixes, it helps construction firms reduce the overall carbon footprint of their projects.

How much product will Green360 Technologies (ASX:GT3) supply under this MOU?

The memorandum of understanding outlines the supply of up to 4,800 tonnes of Eco-Clay over an initial 12-month period. This volume will support Holcim’s concrete operations across Victoria, providing a consistent baseline for Green360’s production requirements.

Is the agreement between Green360 Technologies (ASX:GT3) and Holcim legally binding?

The current agreement is a non-binding Memorandum of Understanding (MOU), which serves as a formal framework for cooperation rather than a final contract. Both companies are currently working toward a binding supply agreement, which they aim to finalise within 90 days.

What recent operational milestones has Green360 Technologies (ASX:GT3) achieved?

The company has reached three major milestones in just seven weeks: signing a toll treatment agreement with Calix, completing its first commercial production at the Bacchus Marsh facility in April 2026, and securing Holcim as a foundation customer.

Who is Holcim and why does their involvement matter for Green360 Technologies (ASX:GT3)?

Holcim (Australia) is a subsidiary of the global Holcim Group, which reported net sales of CHF 15.7 billion in 2025. Partnering with an industry giant of this scale provides Green360 with immediate "blue-chip" credibility and a massive potential distribution network.
