Abstract

The transition to a sustainable bioeconomy is critical for achieving decarbonization, reducing dependence on non-renewable resources, and decreasing greenhouse gas emissions. This project aims to achieve the following: i) evaluate the environmental and economic impacts of bioprocesses using BioSTEAM, a python platform and ii) investigate capacitive deionization as an alternative strategy for industrial separations. BioSTEAM is a free, open-source platform that encompasses the design, simulation, techno-economic analysis (TEA), and life-cycle assessment (LCA) of biorefineries. By applying various parameters and combining process modeling and engineering design with economic evaluation, BioSTEAM helped guide research and development by identifying the most influential factors on cost and sustainability. Regarding capacitive deionization, varying concentrations of aqueous sodium chloride, an inorganic salt, were passed through an electrochemical cell to investigate the effects of concentration on performance metrics. The applied voltage was also varied to quantify the effects on adsorption capacity. The internal stack components were also reassembled and adjusted to attain greater yields. Overall, the BioSTEAM modeling supports the production of [biofuel/product] from [feedstock] through system analysis, and the capacitive deionization experiments provides a basis for the development of an electrochemical separation technology for the separation and recovery of inorganic ions from aqueous solution.
