Landfill gas and energy

Landfill gas, a mixture of methane and carbon dioxide is generated in the landfill body when organic material in waste is anaerobically degraded. Uncontrolled release of landfill gas can create a number of problems including fires, explosions and odour nuisance. Methane is a potent greenhouse gas which is 25 times more powerful than carbon dioxide. But when recovered, landfill gas can also be a valuable renewable energy resource.

Methane generation starts within six to twelve months, then, depending on the waste composition of the landfill site, can continue to be generated for up to 30 years or more. It would be a major contribution to climate change mitigation if landfill gas is recovered and flared at as many landfill sites as possible.

We have several methods at our disposal to calculate how much methane is generated and emitted from a particular landfill site. This can serve as the starting point for introducing measures to recover the methane gas.

Recovered landfill gas can be used to generate electricity, heat or green gas. Instead of being a problem landfill gas can be used for the production of "green energy" and thus create revenues from waste. This way landfill gas projects create great incentives that will improve landfill operation. When unsuitable for energy purposes, landfill gas is burned in a flare to prevent greenhouse gases escaping into the atmosphere. Afvalzorg is highly experienced in landfill gas recovery and utilisation.
