The landfills often tap the fill for methane generated by the contents. I happened to run into a guy the other day who worked at the power generation plant for one of these. The theory is that burning the methane to produce electric, and breaking it down to CO2 is generally preferable than the slow leak of it into the atmosphere where methane has a stronger greenhouse gas effect than CO2. Edit: stronger not "strong"
