1.1. Cups used for drinking can be made from different materials.

Table 1 shows information about paper and ceramic cups.

Table 1

Table 1 shows information about the energy required to manufacture a cup but does not give details of any other energy requirements during other stages of the life cycle.  

Give two other pieces of information about the energy usage during the life cycle that would help to complete a life cycle assessment (LCA).

1.2. Use the information from Table 1 and your knowledge to evaluate the use of paper and ceramic as raw materials to make cups.

1.3. The information given in Table 1 did not provide any information about how much pollution is produced during any of the stages of the life cycle.

Allocating numerical values to indicate the pollutant effect of materials is not straightforward and requires a personal judgment.

What problems could this cause? 

1.4. State the two main stages in the production of ceramic cups.
