"Circular Economy", via renewable energy and resource recovery (2024-2027)
Abstract
In a circular economy context, wastewater utilities are well placed to exploit the commercial potential of microalgae. Sewage treatment plants have an abundance of key nutrients required for algae growth, existing dewatering infrastructure that is suitable for harvesting algae and in some cases, existing anaerobic digestion infrastructure suitable for the conversion of microalgae to renewable energy in the form of biogas. This project aims to upscale wastewater-based algae production that will enable increased renewable energy production via anaerobic digestion, for onsite thermal, electrical energy and upgraded liquefied natural gas.
