Steven Cobb and a team at the University of Durham in the United Kingdom proposes to develop a macroporous scaffold that can support bacterial cells and metal nanoparticles that work together to catalyze conversion of fecal sludge into hydrogen for electricity. This technology could be used as a stand-alone sanitation solution or integrated into existing sewage pipe networks.
