Methane Oxidation

In collaboration with Griffith University, the Company is undertaking industry-led research to develop a process for controlling fugitive methane emissions from landfill. The Methane Control Program, underway since February 2023, has achieved its objective of developing an effective zeolite-based biofilter that adsorbs and eliminates methane emissions through combined chemical and biological oxidation.

The results from the research will also be used to evaluate the potential of our targeted zeoteCH₄® product to be applied for methane emissions control across diverse industries such as mining and agriculture.

Simulated landfill field trials conducted at Griffith University, concluding in May 2025, delivered encouraging early-stage results. The highest-performing zeoteCH₄® biofilter consistently reduced methane emissions by more than 90% compared with control samples under simulated landfill conditions.
