Board 26: Reducing Environmental Impact in Higher Education: Curriculum Design for the Sustainable-Unit Operations Laboratory

Abstract

As outlined in the Paris Agreement, the global commitment to achieving net-zero emissions by 2050 necessitates a multifaceted approach encompassing clean energy initiatives and carbon taxation.Higher education institutions, recognizing their role as key contributors to sustainability, are increasingly focusing on reducing their carbon footprint.The teaching laboratories, essential for various disciplines, contribute significantly to the university's carbon footprint.In this study, we applied the common practices of Life Cycle Analysis (LCA) in the industry to the Unit Operations Laboratory, which resembles the industrial settings yet focuses on teaching and learning that may not have set production scopes nor define operation conditions and processes (i.e. for learning purposes and study impact of various factors on common chemical processes).As learning is the main objective in undergraduate laboratories, LCA methodologies related to laboratory equipment and incorporating technical information on global climate initiatives, clean energy, and the Paris Agreement need to be followed, but some modifications to make such calculations possible.To illustrate the feasibility of this approach, a case study on bioethanol production through yeast fermentation and subsequent distillation processes is employed as a proof-ofconcept.This case study serves as a platform for estimating LCA and redesigning experiments with the aim of reducing the carbon footprint.Since not all chemical process units are designed the same (i.e.sizes, power/production capacity), this project is a collaborative effort internationally amongst universities with similar equipment but different sizes.The carbon footprint approaches, and the preliminary data collected can enable fine-tuning and test the robustness of the approaches and models.The Unit Operations Laboratory emerges as a valuable platform for students to assess their carbon footprint and actively engage in practical LCA applications.This research contributes to the broader goal of embedding sustainability principles within the educational framework, fostering a generation of professionals equipped with the knowledge and skills necessary to address environmental challenges.
