Generating electricity from landfill gas in Brazil

Landfills generate methane as organic waste decomposes. Rather than getting released as emissions, that methane can be captured and used to produce electricity.

 

Over the course of a century, methane has 34 times the greenhouse effect of carbon dioxide. Landfills are a top source of methane emissions, releasing 12 percent of the world’s total. Landfill methane can be tapped, captured, and used as a fairly clean energy source for generating electricity or heat, rather than leaking into the air or being dispersed as waste.

 

The climate benefit is twofold: prevent landfill emissions and displace coal, oil, or natural gas that might otherwise be used.
