A number of the UN’s Sustainable Development Goals (SDGs) concern environmental and climate aspects. The micro-module provides students with background knowledge about the SDGs. The micro-module deals with strategies for dealing with complex global environmental and sustainability problems. Particular focus is placed on technical solutions that are explored in laboratory experiments. In the laboratory exercises, we study how anaerobic digestion can be used to purify organic waste from environmental toxins and produce useful resources such as biogas and fertilizers. Analysing solutions to complex sustainability challenges often requires interdisciplinary expertise. The chemical, biological and physical perspectives applied in the lab environment are therefore integrated with technical and social science knowledge of environmental issues. In this way, the micro-module integrates perspectives from different scientific disciplines in the analysis of complex relationships between the SDGs to identify synergies and avoid goal conflicts.
