Multriwell eliminates the emission of greenhouse gases from landfills, especially methane, which has an up to 28 times higher global warming potential than CO₂. By safely capturing all formed landfill gas, Multriwell prevents uncontrolled emissions and solves any odour nuisance for the surroundings.

Additionally, the recovered gas can be suitable for conversion into renewable energy (electricity and/or heat), thus creating revenues for the landfill operator. Last but not least, via carbon credits additional revenues can be created, that can (co)finance the installation of environmental protective measures, such as a safe capping on the landfill.
