About the Course

Metals are present everywhere around us and are one of the major materials upon which our economies are built. Economic development is deeply coupled with the use of metals. During the 20th century, the variety of metal applications in society grew rapidly. In addition to mass applications such as steel in buildings and aluminium in planes, more and more different metals are in use for innovative technologies such as the use of the speciality metal indium in LCD screens. A lot of metals will be needed in the future. It will not be easy to provide them. In particular in emerging economies, but also in industrialised countries, the demand for metals is increasing rapidly. Mining and production activities expand, and with that also the environmental consequences of metal production. In this course, we will explore those consequences and we will also explore options to move towards a more sustainable system of metals production and use. We will focus especially on the options to reach a circular economy for metals: keeping metals in use for a very long time, to avoid having to mine new ones. This course is based on the reports of the Global Metals Flows Group of the International Resource Panel that is part of UN Environment. An important aspect that will come back each week, are the UN Sustainable Development Goals, the SDGs. Those are ambitious goals to measure our progress towards a more sustainable world. We will use the SDGs as a touching stone for the assessment of the metals challenge, as well as the solutions we present in this course to solve that challenge....

As a Professor of Materials and Metallurgical Engineering, I find this course very useful in presenting new ideas for sustainable systems of metals production and use. The lecturers are very good.

The course itself was absolutely great!

The negative assessment is just and only related to the last asignment. If you mark all evaluations as "good" (which means to me passed) you fail the assignement.

This caused me plenty of approaches to pass which was time consuming and taking the satisfaction from the entire course.

Good course however use of further case studies in the metals / resources sector would be useful. In terms of each unit would be good for a one page summary to be produced at the end of each week to highlight / reiterate key points, themes and definitions from each week

Though the topics is super interesting, relevant and recent, the approach to teaching is super boring! I snoozed off several times just because the instructors are really not engaging, slow to get to the main points, lousy in using visualization , animation or compelling graphics to capture the audience's attention. One of the worst courses , what a pity!
