Young Mexican engineer harnesses waste to generate clean power and purify water

Maritza Sanchez, an engineer from Cuautlancingo in Mexico, is spearheading efforts to deploy microbial fuel cell technology as a means of addressing two critical environmental challenges: energy generation and water purification. Her venture, Aquayac Energy, targets the severely contaminated Atoyac River, one of Mexico's most polluted waterways, using bacteria-based systems to convert organic matter into electricity while simultaneously improving water quality.

Microbial fuel cells operate by harnessing the metabolic processes of naturally occurring microorganisms to generate electrical current. As bacteria break down organic compounds in contaminated water, they release electrons that can be captured and converted into usable electricity. This dual-benefit approach allows the technology to address energy deficits in regions with limited grid access while simultaneously tackling water pollution.

Sanchez's initiative reflects growing interest in bioelectrochemical systems as a sustainable alternative to conventional power generation methods. The technology has potential applications in regions across South Asia and Southeast Asia, where water pollution and energy access remain pressing concerns for millions of people.

According to her projections, Sanchez plans to establish 50 operational microbial fuel cells by 2027. The expansion would significantly increase both electricity generation capacity and the volume of contaminated water treated through the system, while simultaneously creating employment opportunities in the renewable energy sector.
