Microbial fuel cells are presented as the promise of technology to generate electricity by using organic waste. In
this research, molasses waste from Laredo Agroindustrial Company was used as fuel, as well as graphite and zinc
electrodes, managing to build low-cost cells. It was possible to generate voltage and current peaks of 0.389 ± 0.021
V and 1.179 ± 0.079 mA, respectively. The cells showed that acid pH levels and conductivity values were around 100
mS/cm during the period of the highest bioelectricity generation. The maximum power density was 3.76 ± 0.62 W/
cm2 for a current density of 247.55 mA/cm2, showing a peak voltage of 0.459 ± 0.52 V. The yeasts showed a logarithmic
phase up to day 25 reflecting an increase in cell growth. Microbial fuel cells are projected to be the most viable
solution for organic waste and clean energy generation problems.
