Module aims
This module considers the production methods of many chemicals, which are changing rapidly, driven partly by the need to reduce costs but more especially the search for ‘cleaner’ processes. Many factors have to be considered in selecting an ideal ‘clean’ process: the cost of raw materials, energy inputs, process safety, the amount and cost of disposal of waste and the environmental impact of the operation being just some of these. This module will explore changes occurring in the industry and seeks to predict where the industry is heading.
Module learning outcomes
- Students will study different methods of measuring “greenness” and assess their relative merits.
- Students will learn the principles of life cycle assessment in order to quantify the environmental impact of an industrial chemical process.
- Students will gain an understanding of chemical feedstocks, in particular contrasting traditional processes with their new cleaner analogues.
- Students will study the nature and use of sustainable feedstocks, reagents and solvents.
- Students will learn about sustainable energy sources, including biofuels and hydrogen, and the application of fuel cells and microwaves.
- Students will develop an awareness of financial and social factors connected with reducing environmental impact.
- Students will work through case studies in order to apply their understanding in context, in particular sustainable polymers.

Additional assessment information
Group Poster Presentation: Poster submitted by Monday week 7 Spring Term. Poster session on Wednesday week 7 Spring Term with verbal feedback. Written feedback sheet by Friday week 10.
Indicative reassessment

|---|---|
| Closed/in-person Exam (Centrally scheduled) | 80 |
Module feedback
Students will receive ongoing verbal or written feedback on their performance in the formative workshops and on the summative group poster presentation. The closed examinations are marked typically within 4 weeks with mark slips (with per-question break-down) being returned to students at the end of the Summer Term. Outline answers are made available via the Chemistry web pages when the students receive their marks, so that they can assess their own detailed progress/achievement. Examiners reports are made available for each question to the students via the Chemistry web pages.
