Gennaro Trancone is a civil and environmental engineer and researcher specializing in environmental biotechnology, with a focus on anaerobic digestion, dark fermentation, waste-to-energy processes, and the sustainable valorization of waste materials. He earned his Ph.D. in Civil Systems Engineering from the University of Naples “Federico II,” where he developed an innovative bioleaching method for the treatment of construction and demolition waste and asbestos-containing materials. He contributes to teaching and research activities at the same University, serving as lecturer in the Soil Bioengineering PhD course and teaching collaborator in Contaminated Site Remediation, Solid Waste Management, and Sanitary and Environmental Engineering. His scientific interests include biofilm reactors, bioenergy from agro-industrial residues, environmental characterization, and coastal ecosystem monitoring. He is the author of numerous publications in international journals (Elsevier, MDPI, Wiley) on bioenergy, waste treatment, innovative adsorbents, and emerging contaminants. He has presented his work at national and international conferences and serves as a reviewer for more than 20 scientific journals. He is also Guest Editor of the MDPI Special Issue Next-Gen Biofuels. Beyond academic research, he has gained professional experience in industry and public-sector projects, contributing to waste management, wastewater treatment optimization, and marine pollution monitoring.
