The Future of Landfill Gas-to-energy

Operators champion landfill gas as a source of renewable energy and revenue. But as communities seek to divert more organics and climate anxiety intensifies, the practice has been decried as greenwashing.

The full story of landfill gas (LFG) is complicated.

Capturing LFG creates beneficial use opportunities and earns operators revenue, in addition to reducing the global warming potential of the gas that is successfully captured. However, the system may be imperfect from an economic and environmental standpoint. Other forms of electricity generation from waste have efficiency advantages, and the ability of LFG capture systems to effectively mitigate net greenhouse gas emissions is contested.
