There is a very large dairy farm in Michigan which runs all the cattle waste through a methane digestor and this is used to power a couple of large generators. Methane is used to generate all of their electricity plus there is electricity being sold to the power company.

After the bacterial action is completed the waste is still used for fertilizer.


There is a resource on the web on methane generation from livestock waste.
