Zeotech (ASX:ZEO) completes methane control program in partnership with Cleanaway (ASX:CWY) and Griffith University
Biofilter demonstrates effective methane elimination through chemical and biological oxidation
Results achieved under landfill simulation settings with consistent emission rates and weather exposure
Zeotech Limited (ASX:ZEO), listed under the materials sector, has concluded a collaborative methane emissions mitigation program involving Cleanaway Waste Management (ASX:CWY) and Griffith University. Operating within the broader scope of the ASX 200 environmental and materials sectors, the project focused on advancing technologies to manage waste-derived greenhouse gases.
The company has directed its focus towards the development of mineral-based technologies, targeting emissions management solutions in landfill scenarios. The program, launched at Griffith University’s Australian Rivers Institute, reached completion with the development of a zeolite-based biofilter designed to reduce methane emissions generated at landfill sites.
Methane Control Initiative Yields Positive Environmental Outcome
The methane control program involved extensive monitoring and optimisation to establish a robust filtration system. Using engineered layers that emulate landfill soil structure and emission patterns, the field configurations aimed to replicate real-world conditions over an extended research timeline.
The biofilter integrates chemical and biological oxidation techniques. According to project leads, the solution demonstrated high efficiency in adsorbing and eliminating methane without requiring complex maintenance protocols. The aim was to generate consistent results across various landfill types, especially those subject to climate-related operational stressors.
Griffith University Supports Research Outcomes
Griffith University’s research body contributed key scientific oversight through its School of Environment and Science. In-field simulations reflected conditions encountered in medium-scale landfill operations, integrating similar cover materials and emission dynamics. According to the institution, the biofilter maintained its methane removal function across fluctuating weather systems during testing periods.
As field simulations reached operational milestones, the participating institutions indicated alignment between lab-based data and on-ground results. This alignment is regarded as a key factor in the progression of emission mitigation research within waste management infrastructure.
Pathway to Further Application in Waste Management
Cleanaway Waste Management (ASX:CWY), a major national waste management entity, collaborated in facilitating field conditions conducive to testing the biofilter’s viability. The joint program supports future engagement between scientific developers and landfill operators, focusing on practical deployment in waste sites facing methane control challenges.
With landfill emissions remaining a persistent source of greenhouse gases, the integration of low-maintenance solutions that function under diverse conditions presents a strategic step in environmental management practices within the sector.
Zeotech’s Broader Materials Development Framework
In parallel to the methane biofilter initiative, Zeotech (ASX:ZEO) continues to expand its product pipeline using its proprietary kaolin assets. The company’s current initiatives include the production of high-reactivity metakaolin for the low-carbon concrete segment, alongside advanced materials targeted at emissions management, including zeolite-based solutions.
As part of its contributions to the broader materials and environmental technology sectors, Zeotech's program with Griffith University highlights continued development in sustainable materials engineering. These developments contribute to ongoing environmental discussions within ASX 200-aligned sectors, reflecting active industry participation in climate-focused innovations.
