The chart below shows the resources used to make 1000 disposable cups in different materials: polystyrene and paper. Summarize the information by selecting and reporting the main features and make comparisons where relevant.
The chart below shows the resources used to make 1000 disposable cups in different materials: polystyrene and paper. edyGW
The given table compares 1000 disposable cups made of polystyrene and paper in terms of the elements which are used to produce them. We can see from the chart that steam is the main ingredient used to make polystyrene cups and paper cups that consist principally of wood.
According to the statistics, the production of 1000 polystyrene cups needs 8 kg of Petroleum and 13 kg of other chemicals. In addition, Steam is required in large quantities, which is 10 times as much as other chemicals. This process is rather energy-saving because it only needs 0. 6 m3 of water and 6 kilowatts of electricity to generate.
In contrast, in the process of 1000 paper cups, the consumption of water and electricity (10 m3 and 78 kilowatts respectively) is more than the polystyrene cups. It also requires more petroleum, about 18 kg. Moreover, the amount of wood that is needed in the process of 1000 paper cups is much more than in a thousand polystyrene cups. This is an enormous figure, 220 kg. However, the paper cups consume smaller quantities than the polystyrene cups in steam and other chemicals (0. 56 kg and 8 kg respectively).
