Green360 Technologies (ASX:GT3) unveils low-carbon cement using alumina byproduct
Red mud-kaolin blend meets environmental safety and strength benchmarks
Joint venture with PERMAcast advances towards commercial validation
Green360 Technologies (ASX:GT3), part of the industrial and sustainable materials sector, has marked a new development in green construction solutions. The ASX 200 constituent continues to gain attention for innovation in environmental technology. Read more on ASX 200 performance.
The company has successfully transformed red mud, a waste byproduct generated from alumina refining, into a viable component of low-carbon cement. This material breakthrough supports broader environmental goals, aligning with global efforts to repurpose industrial residues for safer and more efficient infrastructure.
Transformation of Red Mud with Kaolin
Red mud is a residual substance formed during the extraction of alumina from bauxite. Its volume and hazardous nature present significant disposal challenges. Green360 has developed a proprietary transformation process involving the use of kaolin to stabilise red mud.
The treatment results in a red mud-kaolin blend suitable for partial substitution of Portland cement. Through this process, uranium and thorium are fully immobilised, and leachability of certain hazardous elements such as chromium is substantially reduced. These advancements position the material blend as an alternative that aligns with strict inert waste and water quality criteria.
Compliance with Performance Standards
Testing of the new cement blend has demonstrated strong structural attributes while maintaining environmental safety. The cement's performance under international guidelines indicates its capacity to meet the demands of commercial applications.
A key metric in material assessment, compressive strength over a standard testing period, revealed that the blend retains a high level of durability compared to traditional cement. These findings reinforce the technical feasibility of introducing this new formulation into construction environments requiring certified strength and safety compliance.
Partnership Supports Commercial Scale Development
Green360 Technologies has entered into a joint venture with PERMAcast to accelerate the path to full-scale deployment. The companies are working collaboratively on validation phases to ensure the blend's readiness for widespread use in civil and industrial projects.
This partnership enables access to production capabilities and industry expertise, facilitating faster transitions from laboratory innovation to real-world utility. Focus remains on replacing traditional cement products with materials that meet both regulatory expectations and practical performance benchmarks.
Environmental Footprint Reduction in Focus
The red mud-kaolin cement blend is positioned to contribute meaningfully to reductions in emissions linked to construction activity. Traditional Portland cement production is a major source of global emissions, and replacing part of its content with industrial byproducts represents a step toward lower environmental impact.
By immobilising radioactive elements and reducing leachability, the solution also addresses key safety issues tied to red mud storage. Green360’s approach supports circular economy goals while enabling compliance with environmental standards across construction supply chains.
As sustainability goals influence decisions across sectors, innovations like this from Green360 Technologies (ASX:GT3) demonstrate shifts in material science focused on waste repurposing and green infrastructure development.
