Zeotech (ASX:ZEO) has reported early trial results from a North Burnett Regional Council (NBRC) landfill using the company’s zeoteCH4Ⓡ technology, reducing methane emissions by around 92%.
The trial at the landfill commenced in February 2026 and is being conducted in partnership with Griffith University. The company noted that it represents the “live operational validation phase” of the program, following successful simulated landfill trials.
The initial report from Griffith confirms that the program is progressing as planned, “with early results exceeding expectations”.
Key highlights from the program include a 92% reduction in methane emissions compared to untreated control cells, with an additional analysis of the methane-to-carbon dioxide ratio demonstrating methane oxidation (reduction) of around 90%.
Zeotech notes that these results support the view that the technology is materially reducing methane emissions at the landfill surface.
The trial has now progressed through the first two stages, with material preparation and blending complete, along with baseline site measurements. Technology testing is now underway, with monitoring to continue through to early August 2026, as the company assesses performance over a longer period of time and across different environmental conditions.
CEO James Marsh says the trial is an important milestone for the company and validates the proprietary technology in real-world conditions.
“Compared with untreated areas of the landfill, the zeolite-treated cells achieved an average 92% reduction in methane emissions during the initial reporting period, with multiple readings exceeding 97% methane elimination, representing an exciting and highly encouraging outcome for a live landfill environment,” Marsh says.
“Importantly, these results have been generated through an on-site trial at a representative regional landfill, reinforcing the program’s commercial relevance and scalability.
“Many Australian landfills do not have gas capture infrastructure in place, and our objective is to develop a practical, passive, and cost-effective methane control solution suited to these operating conditions.”
Dr Chris Pratt from Griffith’s School of Environment and Science and the Australian Rivers Institute also notes that the early results are “highly encouraging and represent an exciting milestone for the program, demonstrating strong technology performance under real-world landfill conditions rather than controlled laboratory environments”.
Zeotech is focused on building a future-focused company, leveraging wholly owned ‘high-grade’ kaolin resources to produce high-reactivity metakaolin for the low-carbon concrete market and advanced materials for greenhouse gas mitigation.
