Yu Chen Guo and Yu Han Guo: A Biological Photovoltaic That Also Treats Wastewater
A Biological Photovoltaic That Also Treats Wastewater.
Yu Chen Guo and Yu Han Guo developed a dual-purpose biological photovoltaic system intended to optimise both electricity output and wastewater treatment. The concept makes the treatment process itself a site for resource recovery.
Innovation mindset: Ask whether cleaning a waste stream can simultaneously produce value instead of consuming resources alone.
Official project title: Dual-Purpose Biological Photovoltaic: Optimizing Power Output and Wastewater Treatment (Environmental Engineering).
