How is the impact of a consumer good or service calculated? A techno-economic analysis (TEA) can help determine economic viability. An environmental life cycle assessment (LCA) can help calculate the total environmental impact. Smith Pittman wants to go further to quantify the social impact.
At a recent Speaker Series, Smith presented her efforts to develop a way to calculate the total social benefits and burdens. Smith hopes the new social impact assessment can be used along with TEA and LCA to create a more complete understanding of the sustainability of products. These tools, used together, can help evaluate proposed processes prior to resource investment.
Smith is a bioprocess engineer at the National Laboratory of the Rockies (NLR) and a 5th year Ph.D. in Mechanical Engineering at Colorado State University. Her research focuses on developing computational and quantitative methods for complex bioprocesses, including process modeling, TEA, LCA, and quantitative social impact assessment (QSIA).
