A Breakthrough in Low-Carbon Cement

Green360 Technologies Limited (ASX:GT3) has announced a significant milestone in its journey to revolutionize the cement industry with low-carbon alternatives. The company has successfully produced high-quality metakaolin from its own kaolin deposits, achieving purity and reactivity levels that surpass many existing metakaolin products both in Australia and globally. This breakthrough positions Green360 at the forefront of sustainable building materials innovation.

Metakaolin, a processed form of kaolin clay, is prized in the construction sector for its ability to partially replace traditional Portland cement in concrete mixes. This substitution not only enhances the strength and durability of concrete but also significantly reduces its carbon footprint, a critical factor as the cement industry faces mounting pressure to decarbonize.

Quality and Performance Validation

Laboratory testing conducted in partnership with Murdoch University confirmed that Green360’s metakaolin contains an exceptionally high amorphous content exceeding 88%, a key indicator of its reactivity and effectiveness in cement formulations. This level of quality outperforms typical metakaolin products, which generally range between 55% and 75% amorphous content.

Unlike other supplementary cementitious materials such as fly ash or blast furnace slag, which can vary in consistency and composition, Green360’s metakaolin offers superior purity and uniformity. This translates into concrete with a denser microstructure, improved longevity, and enhanced structural performance, qualities highly sought after in premium construction projects.

Commercial Trials with Industry Partner PERMAcast

Building on this technical success, Green360 has commenced commercial-scale concrete trials with its joint venture partner PERMAcast, a leading pre-cast concrete manufacturer. These trials are designed to rigorously test the metakaolin-based low-carbon cement formulations under real-world conditions, assessing critical factors such as workability, setting times, temperature sensitivity, and compatibility with admixtures.

The formulations have been developed to comply with Australian Standards, with performance benchmarks set against conventional mixes using Portland cement, slag, and fly ash. Concrete specimens are being monitored over multiple intervals up to 90 days to ensure the product meets stringent structural requirements.

Looking Ahead

Executive Chairman Aaron Banks highlighted the importance of this achievement, emphasizing the company’s commitment to delivering cost-effective, low-carbon cement solutions that can be rapidly adopted by the industry. The ongoing collaboration with PERMAcast and Murdoch University is expected to refine these formulations further, paving the way for commercialisation and broader market acceptance.

As Green360 advances its product development and validation, the company is well-positioned to address the urgent need for sustainable construction materials, offering a promising alternative to the carbon-intensive traditional cement industry.

Bottom Line?

Green360’s metakaolin breakthrough sets the stage for a new era in sustainable cement, with commercial trials poised to unlock market potential.

Questions in the middle?

• How will the results of PERMAcast’s commercial trials influence Green360’s timeline for market entry?
• What are the cost implications of scaling metakaolin production compared to traditional cement manufacturing?
• How might regulatory changes in emissions standards impact demand for Green360’s low-carbon cement?
