Professor Jeehoon Han's research lab specializes in sustainable biorefining and carbon management, focusing on the integrated conversion of lignocellulosic biomass and food waste into advanced biofuels and chemicals. The lab develops innovative catalytic processes and system-level optimization models to enhance the efficiency and economic viability of biorefinery pathways, with a strong emphasis on life cycle assessment and uncertainty-resilient infrastructure planning. Key research directions include the co-production of liquid hydrocarbons from biomass fractions, scalable carbon capture and utilization (CCU) systems, and multiperiod stochastic modeling for sustainable CO2 management. The lab integrates chemical engineering, systems analysis, and environmental sustainability to support the transition toward low-carbon energy and industrial systems.

We develop and evaluate an integrated catalytic conversion strategy, which utilizes both the hemicellulose and cellulose fractions of lignocellulosic biomass to produce liquid hydrocarbon fuels (butene oligomers). In this strategy, the cellulose and hemicellulose fractions are simultaneously converted to levulinic acid (LA), using LA-derived γ-valerolactone (GVL) as a solvent. The LA is then converted to GVL, which is subsequently converted to butene, and then to butene oligomers. To generate th
An integrated assessment method for co-production pathways can give reliable results to decision makers for sustainable development of biorefineries.
Much of the previous research on carbon capture and storage (CCS) has focused on individual technologies for disposing of CO2, such as capture, storage, sequestration, or transport. Moreover, recent research work considers utilization of CO2 as fuels, chemicals, or nutrients for bioreactors. To efficiently manage CO2 and the economic benefits achieved by this process, the CO2 transport and processing infrastructure supporting CCS will have to be constructed at a macro-scale. This paper introduce
A cradle-to-gate life cycle assessment provides comprehensive insights into diverse environmental impacts and possible improvements in producing two formic acids.
Our work aims to identify critical factors that could become equally important in a coincident sustainability assessment of new green energy vehicle technologies with utilization of food waste as an alternative renewable resource to fossil fuels.
