The given chart displays the composition of resources for making 1000 disposable cups in different materials i.e polystyrene and paper. Overall, water, electricity, petroleum and wood were used significantly more in developing the paper cups than polystyrene cups, whereas polystyrene cups comprised more steam usage and other chemicals compared to paper cups.
The 1000 paper cups require 78 kilowats of electricity and 18 kg of petroleum, which is remarkably higher than the quantities required in producing 1000 polystyrene cups. On similar lines, 10m3 of water is consumed in paper cups production, as opposed to 0.6m3 of water for polystyrene cups. Additionally, wood is not at all needed to make the polystyrene cups, while paper cups need a whopping 220 kg for production.
On the other side of the coin, steam and other chemicals (kg) go into the development of polystyrene cups by a notable degree, where 130kg steam and 13 kg other chemicals are used as compared to 0.56kg and 8kg for paper cups.
