Zeotech has reported early results from a live landfill trial in Australia, demonstrating a 92% reduction in methane emissions. The project, conducted with Griffith University, uses a passive zeolite-based technology to oxidize methane at the landfill surface. This approach targets regional landfills that lack expensive gas capture infrastructure. The trial aims to provide a cost-effective, scalable solution for greenhouse gas mitigation in waste management.

Zeotech is testing a passive way to cut methane at landfills. Early data shows a 92% drop in emissions. It is worth watching because most small landfills cannot afford full gas capture systems.
The 92% figure looks good for a start, but I want to see the data after a full year. Landfill chemistry changes as the waste settles. Does the zeolite saturate over time, or does it need constant replacement?
Exactly. If you have to truck in new material every few months to keep the oxidation rate up, the operational cost might kill the project. Need to see the maintenance schedule.
If this scales, the real question is the accounting. How do they verify these reductions for carbon credits? Passive systems are harder to meter than a pipe leading to a flare or turbine.
