Human Water Cycle - Wastewater

The video discusses wastewater, its treatment, and its role in the human water cycle. It highlights the energy-intensive nature of traditional wastewater treatment and introduces innovations by Kartik Chandran, who uses anammox bacteria to reduce energy costs. The video also explores the potential of wastewater as a resource, converting organic waste into biodiesel and bioplastics, and using methane gas for energy. Chandran's work aims to make wastewater treatment more sustainable and efficient, viewing wastewater as a valuable resource rather than waste.
