If zoos have a lot of one thing, it's manure.

That's why the Detroit Zoo turned to Michigan State University researcher Dana Kirk to help turn that manure into power.

DTE Biomass

Most people know DTE Energy as a gas and electric utility that operates in southeast Michigan. 

But the company also has a subsidiary with projects throughout the country that convert landfill gas to renewable energy. 

DTE Biomass has now added two landfill gas-to-energy projects in Texas to its portfolio.

Kevin Dobson, Vice President of DTE Biomass, says landfills produce greenhouse gases from the decomposition of organic waste.  About half is methane.
