Researchers uncover key to converting human urine into usable energy: 'Reducing pressure on freshwater systems'
Scientists have found a way to turn human urine into electricity by mixing it with wastewater and feeding it to bacteria in specialized fuel cells, according to a study published in Results in Chemistry. Treating wastewater takes a lot of energy and money, and the nutrients in what gets flushed typically go unused. Microbial fuel cells tackle both problems at once: Bacteria inside the cells break down organic material in the waste, producing ele…
Human urine is often seen as an uncomfortable waste, something that needs to be evacuated quickly and away. A McGill University team proposes to look at it with other eyes: as a constant raw material, available wherever people are, and with enough organic load to become a biological “fuel”. Their work focuses on a technology called microbial fuel cells or microbial fuel cells (MFCs), capable of transforming organic waste into electricity while a…
