Landfill Gas Management

Methane, which is a main compound of landfill gas, causes 21 to 27 times more global warming than CO2 and presents a potential risk of explosion, intoxication and fire. Where landfill gas cannot be utilized, we offer standardized plants, as well specific individual solutions for the safe collection and disposal of landfill gas.

‍

Our standard modular gas plants are the ideal solution for typical landfill gas with methane concentration of 35% to 55%. The compact plants are skid-mounted or containerized and ready for immediate use in landfills. The basic module comprehends a moisture knock-out pot, a blower, a flare and a completely automatic control system with PLC. Raw- and flue gas analyzers and telemetry are optionally available.  For older and decommissioned landfills, we engineered our LOWCAL flare, which is capable of burning landfill gas with methane concentrations as low as 15%. Hofstetter Gastechnik Gas Management systems offer the highest possible investment security as standard flares can be retrofitted into LOWCAL flares. Even lower methane concentrations of down to 4% can be addressed using flameless oxidation technologies.

For the collection of landfill gas, we offer the full design and build of the upstream degassing solutions from gas wellheads to collector units and condensate shafts.

For CO2 certificate purposes, all of our solutions can be ordered with advanced CDM-ready measurement and control systems. To learn more about CO2 certificate revenue opportunities, have a look at our value concept service.
