  • The trial achieved a 50% reduction in Portland cement within the shotcrete mix.
  • Eco-Clay was tested using standard commercial batching and shotcreting equipment.
  • Green360 identified underground Mining, tunnelling, and civil infrastructure as potential target markets.
  • Green360 shares traded at AUD 0.037 on 7 May, remaining unchanged intraday.

Green360 Technologies (ASX:GT3) traded unchanged at AUD 0.037 on 7 May after announcing the successful completion of a practical plant trial using its Eco-Clay product in shotcrete applications.

The trial was conducted in Partnership with Victorian concrete supplier Eifers Concrete and Complete Shotcrete, with Eco-Clay incorporated into a sprayed concrete mix that reduced Portland cement usage by 50%.

Although the market reaction remained muted, the announcement reflected another step in Green360’s broader strategy to commercialise Eco-Clay across multiple construction and infrastructure applications.

For emerging materials technology companies, practical industrial validation can become an important milestone because it demonstrates that products can operate within existing commercial systems rather than only under laboratory conditions.

In Green360’s case, management positioned the trial as evidence that Eco-Clay can integrate into conventional batching and shotcreting operations while maintaining industry-standard workability and handling characteristics.

Shotcrete Trial Targets New Market Segment

The company stated that the trial involved constructing a demonstration wall section using standard plant, batching, and shotcreting equipment at an Eifers Facility in Victoria.

According to Green360, product handling and workability during the trial were reported as being comparable to existing industry standards despite the significant reduction in Portland cement content.

Shotcreting is widely used across industries requiring rapid concrete Placement, complex formwork, vertical applications, and underground support systems. Typical applications include underground mining, tunnels, rail infrastructure, marine projects, and civil engineering works.

Green360 indicated that demonstrating Eco-Clay performance under practical shotcrete conditions was important for validating factors such as pumpability, nozzle performance, rebound, adherence, and surface quality.

The successful outcome may now support larger-scale field trials and future commercial discussions with shotcrete suppliers and contractors.

Cement Reduction Theme Remains Central

A major focus of the announcement was Eco-Clay’s ability to reduce Portland cement usage.

Cement reduction technologies have attracted increasing attention globally as construction and infrastructure industries face mounting pressure to lower emissions intensity and improve sustainability outcomes.

Portland cement production is widely recognised as a significant contributor to industrial carbon emissions, leading to growing interest in supplementary cementitious materials capable of partially replacing traditional cement inputs.

Green360’s Eco-Clay technology is positioned within this broader industry trend.

The company suggested that shotcrete Demand could provide another pathway to increase utilisation at its Pittong plant, which has a nameplate production capacity of approximately 60,000 tonnes per annum.

Commercial adoption levels, however, will likely depend on broader market acceptance, field performance, pricing competitiveness, and contractor confidence.

Partnerships Support Market Validation

The involvement of Eifers and Complete Shotcrete formed another important aspect of the announcement.

Eifers operates concrete batching and plant facilities across Victoria and services commercial, residential, civil, and infrastructure projects. Complete Shotcrete is described by the company as one of Melbourne’s largest shotcrete applicators.

For early-stage industrial materials companies, collaboration with established industry operators can provide credibility and practical validation pathways that may be difficult to achieve independently.

Management indicated that the successful plant trial now allows the parties to pursue further market opportunities in sectors where shotcreting is regularly used.

Green360 also stated that the trial supports progression toward potential Supply agreements and commercial-scale field programmes.

Commercialisation Remains the Key Challenge

While technical validation is an important milestone, the company still faces the broader challenge of converting trials into sustained commercial adoption.

Construction materials markets are often highly competitive, operationally conservative, and sensitive to performance reliability. New materials typically require repeated testing, certification processes, and contractor acceptance before widespread adoption occurs.

At the same time, sustainability-driven procurement trends may continue creating opportunities for alternative cement technologies capable of reducing emissions and lowering cement intensity.

For Green360, future investor focus may increasingly shift toward:

  • commercial supply agreements,
  • recurring customer adoption,
  • production utilisation rates,
  • and Revenue generation potential.

Bullish and Bearish Perspectives

From a bullish perspective, investors may view the successful shotcrete trial as evidence that Eco-Clay is progressing beyond laboratory validation into practical industrial applications. Supporters could argue that shotcrete represents a meaningful new addressable market across mining, tunnelling, and infrastructure sectors.

The ability to reduce Portland cement usage by 50% while maintaining workability may also strengthen the product’s sustainability positioning.

From a bearish perspective, commercial construction markets often adopt new materials slowly due to certification requirements, operational risk concerns, and established supply chain relationships. Successful trials do not necessarily guarantee commercial-scale adoption or meaningful revenue generation.

Some investors may also remain cautious around production scalability, customer conversion timelines, and broader competition within the low-carbon cement materials sector.

About the Company

Green360 Technologies (ASX:GT3) is focused on developing and commercialising sustainable construction material technologies.

The company’s Eco-Clay product is designed as a supplementary cementitious material aimed at reducing Portland cement usage across concrete applications.

Industry Trends and Market Context

Global construction and infrastructure sectors continue facing increasing pressure to reduce carbon emissions and improve environmental performance. Cement replacement technologies and alternative supplementary cementitious materials have become an important area of industry focus as governments and contractors pursue lower-emission construction solutions.

Shotcrete demand remains significant across underground mining, transport infrastructure, tunnelling, and marine protection projects, particularly as governments globally continue investing in major infrastructure programmes.

At the same time, adoption of new construction materials often depends on technical performance validation, regulatory acceptance, pricing competitiveness, and contractor familiarity.

Companies capable of demonstrating compatibility with existing infrastructure and construction workflows may improve their chances of broader industry adoption.

Investment Risks and Challenges

Green360 faces commercialisation and market adoption risks common to emerging industrial technology companies. Successful plant trials may not necessarily lead to long-term supply agreements or widespread industry acceptance.

The company also remains exposed to construction market cycles, production scalability challenges, competitive technologies, and regulatory approval processes linked to building materials standards.

Commercial success will likely depend on customer adoption rates, operational execution, pricing competitiveness, and broader demand for low-carbon construction materials.
