WLSSD Biogas

The Western Lake Superior Sanitary District handles the wastewater for Duluth and the surrounding area. They needed a way to simplify and explain their biogas program. They collect the gas produced by sludge left over from the sewage treatment process, and convert it into usable energy, in the form of heat and electricity. As icky as that process may be, the animation turned out quite nice, and kind of cute.
