Microbial Fuel Cell: Novel Anaerobic Biotechnology for Energy Generation from Wastewater

World energy demand is expected to rise from 421 quadrillion British Thermal
Units (BTUs) in 2003 to 563 quadrillion BTUs in 2015 and 722 quadrillion BTUs
in 2030 (USDOE 2006). Energy production from renewable feedstocks holds great
potential to meet these needs in a sustainable and environmentally sound manner,
and to reduce dependence on fossil fuels.
At the same time, impairment of water resources requires increased investment
in water and wastewater treatment infrastructure. Some estimates of the needed
investment in the United States approach $1 trillion over the next 20 years (Water
Infrastructure Network 2007). Energy generation from “negative-value” waste
streams can simultaneously help meet the world’s energy needs, reduce pollution,
and reduce costs associated with water and wastewater treatment.
