Wastewater to energy: New treatment process can improve biorefinery sustainability
URBANA, Ill. -- Wastewater from biorefineries that convert plants into fuel is full of organic materials that cannot be efficiently treated with conventional wastewater systems, making it costly and energy-intensive to manage.
However, those rich organic materials are an untapped source of chemical energy that can be recovered as valuable products, including biogas, a clean-burning renewable fuel.
