Mineral processing technology company Zeotech (ASX:ZEO) has yielded promising early results from its Methane Control Program, which is being run at Queensland’s Griffith University in collaboration with Cleanaway Waste Management.

Crucially, the study shows the company’s two zeoteCH₄ products are able to achieve a mean efficiency of between 70 and 85% in reducing methane emissions, with these results being taken from simulated landfill configurations.

Zeotech’s zeolite-based products also show a much more impressive performance than the third configuration containing methanotroph inoculum-only, which did not show any ability to reduce methane emissions.

These studies arise from recognition of methane’s status as the second most significant greenhouse gas (GHG) with a 100-year global warming potential 28 times greater than carbon dioxide and landfills release just under one billion tonnes of atmospheric CO₂-e methane per annum.

Dr Chris Pratt from the Australian Rivers Institute at Griffith University’s School of Environment and Science, said that this early-stage work had provided optimistic expectations.

“Griffith University values its technical partnership with Zeotech and the positive outcomes we have achieved over the past two years, culminating in these promising early pilot-scale field results averaging 70-85% methane removal over the September to November period, further validating the potential for zeoteCH₄® technology to control methane emissions,” said.

“We look forward to working closely with Zeotech and Cleanaway to progress to the nextphase, targeting on-site landfill trials in 2025.”

Zeotech has been trading at 5.1 cents through Tuesday morning.
