Capture of Biogas from Landfills
- 2.6k Downloads
Sanitary landfills begin releasing biogas within a few weeks of being laid out and continue to do so for several decades. It has been estimated that as much as 12% of the total global methane emission is contributed by sanitary landfills. Till recently sanitary landfills were predominantly located in developed countries but as developing countries also begin taking resort to sanitary landfills, the landfill-based methane emissions are expected to rise.
This chapter describes the manner in which sanitary landfills are laid out and the way in which biogas is generated therein. It then describes the methods with which landfill gas is captured and purified for use as an energy source. The environmental and safety issues related to landfill gas generation and capture have also been addressed.
