1.1. It is becoming increasingly more important for chemists to develop manufacturing processes sustainably.

Explain what is meant by sustainable development and how chemists play a role in sustainable development.

Include an example in your answer.

1.2. Carrier bags are often made from poly(ethene) but chemists have developed bags that can be made from other materials including one made from corn starch.

Table 1 shows some information about the bags made from these materials.

Table 1

Evaluate the use of poly(ethene) and corn starch to make carrier bags, commenting on the sustainability of the production and disposal of both types of bags.

Use the information in Table 1 and your understanding of LCAs to help you answer.
