Case study: Microplastics in cosmetics

Case study: Microplastics in cosmetics
Learning Objets
Summary
This case study involves a young engineering student on an industrial placement year at a firm that manufactures cosmetics. The student has been working hard to impress the company as they are aware that this may lead to them being offered a job upon graduation. They are involved in a big project that focuses on alternative, more environmentally friendly cosmetic chemistries. When they notice a potential problem with the new formulation, they must balance their commitment towards environmental sustainability with their desire to work for the company upon graduation.

This dilemma can be addressed from a micro-ethics point of view by analysing personal ethics, intrinsic motivations and moral values. It can also be analysed from a macro-ethics point of view, by considering corporate responsibility and intergenerational justice. The dilemma can also be framed to emphasize global responsibility and environmental justice whereby the engineers consider the implications of their decisions on global communities and future generations.

The case study is a part of the Engineering Professors Council and Royal Academy of Engineering's Engineering Ethics Toolkit and was authored by Dr. Natalie Wint.

Excellent resource, thank you. It will help me show my undergraduate students how green chemistry impacts ethical, environmental, and even economic decisions. In other words, it helps show them the impact of chemistry on sustainable development and encourages them to start thinking about their role as future environmental engineers.
