Simphiwe Gift Nkuna, a Tshwane University of Technology (TUT) Master's graduate from the Faculty of Engineering and the Built Environment’s (FEBE)) pioneering research on sustainable energy recovery from municipal wastewater sludge, was recognised on 9 May, during the recent autumn graduation ceremonies at the Pretoria Campus, when he graduated Cum Laude.
Nkuna, from FEBE’s Department of Electrical Engineering (DEE)/ French South African Institute of Technology’s (F'SATI), significant research has been published widely in reputable scientific journals and peer-reviewed conferences, including the Institute of Electrical and Electronics Engineers (IEEE) and Elsevier's ScienceDirect. Collectively, these articles have received in excess of 40 citations, reflecting the study's impact and relevance within the scientific community.
His dissertation, titled "Multi-Process Extraction of Electrical Energy from Municipal Wastewater Sludge," explores integrating thermochemical conversion technologies with Combined Heat and Power (CHP) systems to generate heat and electricity from wastewater sludge.
“This innovative approach aims to transform wastewater treatment plants into energy-producing facilities, aligning with global efforts toward sustainability and circular economy principles. It also facilitates access to clean energy research and technology, including renewable energy, energy efficiency, advanced and cleaner fossil-fuel technology, as well as promoting investment in energy infrastructure and clean energy technology,” said Nkuna.
Prof Thomas Olwal, Head of DEE and Nkuna’s research supervisor, said Nkuna's success reflects both his commitment and academic excellence and places TUT at the forefront of sustainable energy research.
"His work contributes to the broader conversation on renewable energy and resource recovery, offering practical solutions to the environmental challenges urban communities face. His achievements inspire fellow students and demonstrate the University's commitment to fostering innovative research that addresses real-world problems. This initiative aims to reduce the negative per capita environmental impact of cities, focusing on air quality and the management of municipal and other waste," Prof Olwal said.
