Manufacturing of organic chemicals has historically largely been dependent on petroleum feedstocks, a finite resource which is becoming increasingly expensive and for which renewable replacements are needed. Green Chemistry is helping to drive forward the uptake of renewable resources as a substitute for fossil feedstocks and to move towards a more circular economy approach in resource utilisation. 
By the end of this module you should:
- Understand the need to change the current sources of raw materials;
- Understand the different types of renewable materials available to us;
and be able to:
- Define what a platform molecule is;
- Describe the main components of biomass.
