This could potentially stimulate the Chicago regional economy by locating a plastics partner near the treatment plant and reduce reliance on petroleum. The MWRD is supporting leading-edge research in this field to help make algae technology a practical and sustainable approach to nutrient management for urban wastewater treatment plants.
