Paragraph starter

Microbial electrochemical technologies (METs) present a promising avenue for sustainable resource recovery from wastewater, offering the potential to generate electricity and recover valuable nutrients. Research indicates that METs can effectively treat wastewater while simultaneously producing energy carriers like hydrogen and methane, aligning with circular economy principles. However, challenges in scaling up, high capital costs, and material limitations currently hinder widespread commercial adoption. Future design efforts should focus on optimizing electrode materials, modular configurations, and integration with existing infrastructure to enhance performance and reduce costs.
