India, Feb. 17 -- Researchers tested microbial fuel cells using 20%, 50% and 75% urine mixtures

Systems with 50-75% urine produced the highest electricity output

Urine nutrients accelerated microbial growth and pollutant removal

Shifts in bacterial dominance affected energy generation efficiency

Technology could support low-cost sanitation and off-grid communities

Researchers have refined a technique that turns human urine into electricity, advancing a low-cost approach to both wastewater treatment and renewable energy generation.

A team of bioresource engineers at McGill University found that higher concentrations of urine significantly improve the performance of microbial fuel cells (MFC). MFCs are devices that use naturally occur...
