What innovative process do some cities use to transform wastewater into renewable energy?
Anaerobic digestion
Anaerobic digestion is a biological process that breaks down organic matter in the absence of oxygen, producing biogas, a source of renewable energy. Modern wastewater treatment facilities incorporate this technology to convert waste into energy, thereby reducing reliance on fossil fuels and minimizing the ecological footprint of cities. This process exemplifies how waste can be transformed into resources, contributing to a more circular and sustainable economy.
