The Original Recyclers

The Shakopee Mdewankanton Dakota community tries very hard to be self-sufficient.  Having that giant casino helps, no doubt.  They have their own water-treatment plant, DNR department, police and fire, and an energy cooperative.  And I have to say, this energy plant is genius.  All of the materials burned in this plant would just be waste otherwise.  Barley dust from beer production?  Oat hulls from Cheerios?  Genius.
