ENGR 22b Engineering a Circular Economy
[ sn ]

The way we produce, use, and dispose of materials and products today is unsustainable. Resource extraction destroys ecosystems and biodiversity worldwide; manufacturing is responsible for an enormous fraction of global greenhouse gas emissions; and waste plastics are now found in every corner of the earth, including our bodies, with as-yet unknown consequences to human and ecological health. The circular economy is a model of production and consumption that offers a potential solution to these problems -- where all materials and products are designed to be used, reused, and recycled again and again, minimizing environmental impact from resource extraction, manufacturing, use, and final disposal.

In this class, students will learn what is required to realize this vision of a circular economy from an engineering and design perspective. Based on a methodological foundation from industrial ecology, students will use life-cycle assessment and material flow analysis to characterize the profound issues with contemporary manufacturing and waste systems, and justify the principles of materials and product stewardship that underpin the circular economy model. Students will also learn to critique materials management and circular economy proposals at various scales, including materials and product design, so-called "circular business models," and municipal, national, and global materials systems. Finally, students will use what they have learned to propose new engineering design solutions to real-world challenges. Usually offered every second year.
