Dr. Anex’s research is focused on developing and assessing systems for producing energy, fuels and products from biorenewable resources. For example, Dr. Anex’s research group is studying economic and environmental feasibility of biorenewable chemicals being developed in the Engineering Research Center for Biorenewable Chemicals (CBiRC), nutrient recovery and cycling in biofuel systems, and impacts of biomass production on the hydrologic cycle.
Dr. Anex’s research combines process development in the laboratory with large-scale model-based assessment of agricultural-industrial systems. Key tools used to evaluate the economic efficiency and environmental sustainability of biobased products are Life Cycle Assessment (LCA) and Techno-economic Analysis (TEA). Dr. Anex and his students have been working to improve LCA and TEA methods to address the unique ways that biorenewable products couple agricultural and industrial systems.
