(59b) Novel Framework To Examine Sustainability Of Biorefining Processes

As the recent research is exploring possibilities for developing renewable bio-based fuel, there arises a need for a supporting model that guides the existing research to the appropriate path of process and product design. Biomass as a potential feedstock raises concerns on long term feasibility of this nonconventional method amidst increasing greenhouse gas emissions and growing demand for energy and transportation fuel. Considering the challenges inherited due to the inclusion of biomass as feedstock, a model is developed, demonstrating an innovative multidimensional approach to create a framework for comparing various processes and analyzing their upstream and downstream supply chain effects. This concept shows developing, interfacing and linking of various multidisciplinary optimization models utilizing supply chain modeling and process systems engineering skills. To illustrate its applicability, a case study is performed in the Jackson Purchase region in Western Kentucky. Initially, the model developed will encompasses various financial parameters involved in major conversion techniques pursued in the given region of interest. On evaluating the locally available biomass feedstock, thermochemical and biochemical processes for the production of energy and transportation fuels weredetermined to be the possible options. Subsequently, this analysis involving variable costs and capital investments will be appraised for its environmental and societal impact, capturing all possible aspects of sustainability. The resulting model is unique and informative in assisting policy makers and various stakeholders for evaluating sustainability of biofuels in any given region. Finally, the model can be applied to many other regions due to its generalizability, making it a powerful tool for assessing multiple facets of sustainability.
