Abstract:
Food, energy and water systems interact closely with environment (food-energy-water-environment nexus). Interdisciplinary research to enhance energy and resource recovery from various sources is needed to address the complex nexus challenges. Thermophilic solid-state anaerobic digestion is promising for bioenergy production from high solid wastes (e.g. lignocellulosic biomass). A sequential batch solid-state anaerobic digestion process has been developed and optimized. Improved methane production and adapted microbial community were obtained. The system’s technical and economic feasibility has been compared to composting to facilitate decision-making. Electro-active microbes can be incorporated with anaerobic digestion to further enhance process efficiency and stability. They promote direct interspecies electron transfer instead of interspecies H2 transfer. Conductive materials (e.g. carbon fibers, magnetite) can be effective to enrich various electro-active microbes. Alternatively, photocatalysts can also potentially convert CO2 to fuels under visible light at low cost. Computational modeling can be useful to reduce empirical costs as a complementary tool.

Long Lin received her doctorate in environmental science from The Ohio State University in 2017. She is currently working as a post-doctoral fellow at the University of Alberta, Canada. Her research interests and experience focus on environmental biotechnologies and bioprocesses for energy and resource recovery from bioresources, wastewater, and organic solid wastes. She has worked on bioprocesses like anaerobic digestion, composting, acidogenic fermentation and microbial electrochemical systems. She also has experiences in techno-economic analysis, computational fluid dynamics modeling and nanotechnology. She earned her bachelor’s degree in environmental engineering from Sun Yat-sen University, China in 2010 and master’s degree in environmental science and engineering from Nanyang Technological University, Singapore in 2011. She has also been to Stanford University for a two-month program during summer 2010. To date, she has published 10 peer-reviewed journal articles in journals including renewable and sustainable energy reviews, bioresource technology, waste management, and energy and fuels.
