This free course will cover the role chemists play in achieving the United Nations Sustainability Development Goals and helping to ensure a sustainable future for the planet. In particular, it looks at how chemicals can be manufactured (at scale) whilst minimising any detrimental environmental impact – leading to a discussion of the principles of Green Chemistry and production of ammonia by the Haber-Bosch processes. Using mobile phones as a focus, the course will look at elements that are likely to be in short supply in the future, and the increasing necessity for urban mining.
