Description

Life cycle assessment (LCA) is widely accepted as the gold standard of holistic environmental impact analysis tools. The LCA methodology was developed to assess the impact that industrial practices have on ecological and biological systems by measuring lithospheric (terrestrial toxicity), hydrospheric (freshwater and marine toxicity, eutrophication), and atmospheric (global warming, acidification, ozone depletion) emissions from a given product system. Within the scope and framework of LCA practice, is the identification of carbon-intensive unit processes, or ‘hotspots’ within a system, and the potential for decarbonisation innovation. This forms a natural synergy between the LCA methodology and decarbonisation initiatives. The objective of this module is firstly to educate students on the concept of “the lifecycle” as it pertains to a product, system, or service. The students will then develop the knowledge and skills required to carry out Carbon Footprinting as part of a full LCA study of a product system. The students will become familiar with, and learn to interpret the ISO 14040 series of LCA standards. Students will develop LCA models for a given product system using LCA software, present their results and make recommendations.

Learning Outcomes

1. Understand the concept of life cycle thinking and its application to engineering
2. Understand and apply the LCA framework as defined by the ISO 14040 series of LCA standards
3. Compile life cycle inventories for a range of engineering product systems
4. Conduct life cycle impact assessments with suitable impact assessment methodologies
5. Conduct carbon footprinting on a range of product systems and services
6. Identify and develop decarbonisation opportunities in industrial applications
7. Apply chemical exergy analysis to quantify resource use
