Zeotech (ASX: ZEO) will commence a major on-site validation trial of its methane emissions control solution at a North Burnett Regional Council landfill, following execution of a research agreement with Griffith University.
The trial marks the next stage in commercialising the company’s Methane Control Program after successful simulated landfill trials completed in May 2025, and will test Zeotech’s zeoteCH₄ biofilter technology over a six-month period under real-world operating conditions.
The trial will utilise the highest-performing zeoteCH₄ biofilter identified during earlier simulated landfill testing at Griffith, in which – aside from a short period impacted by extreme rainfall – the biofilter consistently reduced methane emissions by more than 90% relative to controls.
Zeotech will use data from the on-site program to further refine biofilter development, maintenance requirements, and optimal operating conditions.
The company said the move from simulated environments to a live site represents a critical step in demonstrating commercial readiness.
Program Structure And Data Collection
Trial activities commencing in February 2026 will span a seven-month program comprising preparation, baseline methane measurements, and live technology testing.
Zeotech expects to collect and analyse more than 800 data points to assess methane oxidation performance in a real landfill environment, with the trial design also supporting optimisation of the system to maximise methane elimination rates.
The selected North Burnett site is representative of many small-to-intermediate regional landfills across Australia that operate without gas recovery systems.
Zeotech said most of Australia’s 1,168 operational landfills lack methane capture infrastructure due to cost and compliance constraints, and believes its non-invasive, passive biofilter solution is well suited to these conditions and could address a significant unmet market.
Cost-Effective Methane Solution
“This is a pivotal milestone for Zeotech as we progress our Horizon 2 methane emissions control solution from simulated environments to real-world validation,” chief executive officer James Marsh said.
“This program will demonstrate the practical application of our zeoteCH₄ technology and its potential to deliver a cost-effective solution for landfill methane mitigation, addressing a critical challenge in achieving Australia’s emissions reduction targets.”
Griffith University researcher Dr Chris Pratt said the trial would provide the opportunity to confirm earlier results at operational scale.
“If successful, the technology could offer landfill operators a practical and scalable solution to materially reduce methane emissions and make a meaningful contribution to Australia’s climate objectives,” Dr Pratt said.
