Keywords:
wastewater, bioelectricity, microbial fuel cells, alternative energies, human urineAbstract
From an early age, society instills in us a prejudice towards our physiological waste. Urine and feces are associated with poor hygiene. However, in a healthy person, urine is a bacteria-free liquid that originates in the kidneys and its main components are water and nutrients. In the last decade scientists have shown an interest in studying human urine as a possible fuel and water source; To this day, some models of batteries have been invented that use bacteria to convert human urine into electrical energy. Although still under development, urine-based bio-batteries have shown interesting and promising results.
