Florida City Will Soon be Powered by its Own Poo

Florida Town Turns Sludge into Energy
Florida, United States [RenewableEnergyWorld.com]
Sanford, Florida will be the first municipality in North America to  
adopt the MaxWest gasification system to dispose of biosolids. MaxWest  
Environmental Systems has developed the gasification system, which  
converts sludge from the municipal wastewater treatment system into  
energy.

"Compared to the projected cost of natural gas, a fossil fuel, Sanford  
will save $9,000,000 over the 20-year life of our contract. This  
technology has provided us with the opportunity to save money while  
managing our waste stream and protecting the environment."

--Paul Moore, Utility Director, City of Sanford
MaxWest will build a facility at a wastewater treatment plant. The end  
product of a sewer plant, wastewater sludge, also called biosolids,  
will be gasified in an enclosed primary gasifier to produce syngas. In  
a continuous integrated process, the syngas will be oxidized in an  
enclosed thermal oxidizer to produce thermal energy. ForSanford, the  
thermal energy will replace natural gas to power a new dryer.

"Compared to the projected cost of natural gas, a fossil fuel, Sanford  
will save $9,000,000 over the 20-year life of our contract," said Paul  
Moore, the city's utility director. "This technology has provided us  
with the opportunity to save money while managing our waste stream and  
protecting the environment."
