Yes. I have posted on this before. All class 4 landfills produce methane gas which is generally burned off.
I have to give credit to Waste Management, they are one of the first to use the Methane gas in their plants, and on the sites.
In Northern Arkansas, they even convert the methane gas into fuel for their heavy equipment.
It is not so expensive to pipe this gas, it is just that there isn't enough profit to be generated since it comes from an abundance of garbage.......Some day soon, when there are regulators and administrators.....
One person commented that landfills letchete goes into the ground and contaminates water tables...if they are they are in violation of reg. 22 and they will be fined and a clean-up will ensue. Until Katrina landfills were regulated by EPA on a Fed level and Dept of Environmental Equality on the State levels.
If you know of a landfill whose 2 ft of clay liner, and geosynthetic liner is leaking, notify your Dept. of Environmental Quality......
imho & over 8 million square feet of liner installation inspection
