Day 1 :
National I-Lan University
Keynote: Exploring optimal supplement strategy of medicinal herbs and tea extracts for bioelectricity generation in microbial fuel cells
Time : 9:00 - 9:30
Bor-Yann Chen has expertise in biomass energy and environemntal biotechnology. His serial stuides focused on applications in wastewater treatment, bioremediation engineering, biofuel cells. He completed PhD from University of California, Irvine in 1995 and used to be NRC awarded Research Associate to work in NRMRL/US EPA, Cincinnati Ohio. He is Professor, Department of Chemical and Materials Engineering, National I-Lan University, Taiwan. He has published 150+ SCI-peer reviewed papers in reputed journals and has many National Awards (e.g., Professor Yen-Ping Shih Best Paper Awards of 2007, 2011, 2013 and 2016 from Taiwan Institute of Chemical Engineers).
This first-attempt study used extracts of appropriate antioxidant abundant Camellia and non-Camellia tea and medicinal herbs as model electron shuttles (ESs) to stably augment bioelectricity generation performance in microbial fuel cells (MFCs). As ESs (or redox mediators) could stimulate electron transport phenomena by considerable reduction of electron transfer resistance, the efficiency of power generation for energy extraction in microbial fuel cells (MFCs) could be appreicably augmented. That is, using environmentally friendly natural bioresource as green bioresource of ESs is the most promising to sustainable practicability. As comparison of power-density profiles indicated, supplement of Camellia tea extracts would be the most appropriate, then followed non-Camellia Chrysanthemum tea and medicinal herbs. Moreover, antioxidant activities, total phenolic contents and power stimulating activities were all electrochemically associated. In particular, the extract of unfermented Camellia tea (i.e., green tea) was the most promising ESs to augment bioenergy extraction compared to other refreshing medicinal herb extracts
Delta State University, NIGERIA
Dr. Kigho Moses Oghenejoboh who is currently an associate professor in environmental studies at the Delta State University, Abraka – Nigeria holds a PhD in Chemical Engineering. He is an ardent scholar and the head of the Bio-environmental Laboratory of the University. He has published more than 35 papers in reputable journals covering a wide range of environmental issues. He also attends and present papers at major international conferences on environment annually.
Effective waste management require a multidisciplinary approach with Chemical Engineering as the fulcrum. The problem of sustainable waste management is as old as creation itself, for the creator of the universe put ecological cycle in place to effectively manage waste generated in the universe either through recycling or conversion into useful products. It can rightly be said then, that the Almighty God started the profession of Chemical Engineering. However, over the years, man had succeeded in destroying this perfect system put in place by God either through greedy manipulation of the system or out of ignorance. Over the past decades, Chemical Engineers in collaboration with Biotechnologists and Environmentalists have been working tirelessly to see how wastes generated from various industrial processes including the agro-based industries can be used sustainably in the treatment of industrial wastewater, generate energy or converted to useful chemical products. Agricultural wastes are unwanted materials produced from agricultural processes like growing of crops or raising of animals. One area of great success is the use of agricultural crops waste as polymerized biochar for the adsorption of lethal heavy metals from wastewater. In tropical Africa like Nigeria, an important agricultural product that generates a lot of waste is cassava, a vital staple delicacy. The leaves, peels, stems and wastewater from the processing of this agricultural product poses great environmental nuisance. However, the leaves, peels and stems are currently being put to economic use either as animal feed or as biomass for wastewater treatment. Research is presently on-going in the utilization of the large volume of wastewater generated from cassava processing for the cultivation of microalgae. In this review, the potential of cassava wastewater in growing microalgae for algae crude production is enumerated. The economic benefit of the venture as a supplement to Nigeria’s dwindling fossil fuel reserve as well as its positive impact on environmental sustainability are discussed
