Abstract |
Wastewater treatment plants (WWTPs) may play a crucial role in shifting to a zero-emission future by becoming more sustainable and contributing to the circular economy (CE). Recovered lipids from urban sewage can serve as a raw material for biofuel production contributing to a waste reduction, mitigation of natural resources depletion and reinforcing security and energy independence. A novel, pilot-scale lipid accumulation technology (LAT) employing parameters to select M. parvicella for the biofuel/biodiesel production was implemented on a side stream of an urban WWTP. The LAT proved its concept as the average amount of extracted lipids accumulated in the bioreactors was three-fold higher when compared to the lipids existing in activated sludge. The average transesterification of extracted lipids to biodiesel resulted in a 1.6 % yield, meaning that from 1 kg of dried sludge, 16 g of biodiesel could be formed. The biodiesel produced complies with European standard specifications (EN14214). |
