Description: Selected greenhouse gas and air pollutant emissions from municipal wastewater treatment plant energy supply scenarios were quantified and compared. In all scenarios, anaerobic digester biogas-fuelled energy recovery systems were utilized to meet thermal energy and electricity demands. Any demands not met by energy recovery systems were supplied by natural gas-fuelled boilers and the regional power grid. Each of the four scenarios analyzed included one of four energy recovery systems: boilers (the most common scenario), cogeneration internal combustion engines, cogeneration microturbines, or cogeneration phosphoric acid fuel cells.All of the cogeneration scenarios when compared to the Boiler Scenario lowered facility greenhouse gas emissions by more than 40% and sulphur dioxide emissions by more than 50%. In addition, the Fuel Cell Scenario lowered nitrogen oxide, carbon monoxide, and total particulate matter emissions by more than 50%. For the Internal Combustion Engine Scenario, nitrogen oxide emissions were 50% greater than the Boiler Scenario.
