Turn CO₂ in Biogas into Extra Methane and Extra Revenue.
MethaneMax helps farm and commercial biogas plants turn waste CO₂ into extra methane, boosting your output and revenue.

Up to 40% of Your Biogas Is CO₂ and It’s Untapped Energy
Most biogas plants generate biogas containing 35–45% CO₂, which is typically released or not fully utilised. This means a significant portion of your gas has additional methane potential that remains unexploited.
By valorising this CO₂ and converting it into extra methane, plants can boost biomethane yield, improve overall efficiency, and unlock new revenue opportunities without major changes to existing infrastructure.

How MethaneMax Works
Use the CO₂ Already in Your Biogas
MethaneMax connects to your existing biogas line and takes the CO₂ naturally present in raw or upgraded biogas. Instead of releasing or discarding this CO₂, the system channels it into our catalytic reactor.
Convert CO₂ with Renewable Hydrogen
The CO₂ is reacted with renewable hydrogen in our catalytic system (Sabatier-based process) to produce additional methane with high selectivity.
Boost Your Biomethane Output
The newly generated methane is blended back into your gas stream, increasing saleable biomethane yield without adding extra feedstock or major changes to your plant.
Smarter CO₂ Conversion, Built for Biogas Plants
MethaneMax is a modular add-on that turns waste CO₂ from AD plants into extra methane. Simple to integrate. Powerful in return.
Boost Gas Output
Convert the CO₂ already present in your biogas into usable methane, increasing overall biomethane yield.
Cut Carbon Emissions
Reduce overall greenhouse gas emissions with a cleaner, more circular methane production process.
Qualify for Green Incentives
Strengthen your plant’s sustainability profile and improve eligibility for future green incentives, subsidies, or carbon credit schemes.
Integrate Without Disruption
Low-CAPEX, modular system that integrates with your existing biogas setup with minimal modifications and minimal downtime.

Who MethaneMax Is For?
AD biogas plants
MethaneMax is ideal for anaerobic digestion plants looking to maximise gas yields. If you’re currently releasing CO₂, this system helps you convert it into usable methane – boosting revenue from your existing setup.
Farm-based digesters
Designed with low-maintenance needs in mind, MethaneMax integrates easily into agricultural biogas units. It helps farmers generate more methane from the same feedstock without additional inputs or complexity.
Food/agri-waste processors
For facilities processing food or agricultural waste, MethaneMax improves methane yield and carbon efficiency. It’s a powerful add-on for waste-to-energy operations aiming to enhance sustainability and profit margins.
Municipal and wastewater operators
MethaneMax supports municipal sites using anaerobic digestion for sludge or organic waste. It improves gas recovery and helps meet decarbonisation goals – without major upgrades or disruption to service.
