Building Life Cycle Assessment skills with GREET and SimaPro to engage students in analyzing the sustainability of biofuel alternatives
Abstract Engineering students take two Sustainable Engineering courses focused on understanding of the environmental, social, and economic impacts of design and technology by exploring the relationships between industrial and ecological systems. This paper focuses on the second part of the two course sustainability sequence that is a problem-based course based on quantifiable life cycle analysis using multi-parameter sustainability tools, including footprint analysis, GREET LCA software and Sima Pro LCA software.
This paper discusses the implementation of a semester-long deep-learning project designed for students to engage with and compare GREET and SimaPro LCA platforms for analyzing the environmental impacts associated with biofuel production from ethanol and miscanthus.
The Greenhouse gases, Regulated Emissions and Energy in Transportation (GREET) model has become the standard in performing life cycle analyses of transportation fuels. The GREET model focuses on energy options and is idea for introducing students to the goal and scope, system boundaries, pathways and process analysis required for Life Cycle Assessment. The GREET output provides a greenhouse gas indicators and other pollutants, but does not cover the comprehensive environment and health impacts that are associated with other LCA packages and databases.
SimaPro is the world's leading life cycle assessment (LCA) software employed by businesses, consultants and research institutes in more than 80 countries. SimaPro is a comprehensive LCA package that utilizes the EcoInvent database. This software was introduced to students in their second deep-learning exercise and allowed students to develop a SimaPro based LCA and evaluate and interpret the multiparameter outputs from the LCA.
This paper will include the deep-learning assessments assigned to the students, examples of student work, a summary of student perceptions of the course and placed-based project and a mixed-methods assessment of the course.
