The given diagram compares the amounts of resources used to make two types of disposal cups: paper and polystyrene cups. Overall, paper cups need a greater number of materials, whose harmful emissions are significantly less than polystyrene cups.
It is immediately apparent that the production of polystyrene cups makes 100kg steam and 13kg chemicals particles per 1000 cups, representing a dangerous nature for the globe. However, the production of paper cups drains just half of a kilogram steam and 8kg chemicals particles per 1000 cups. Additionally, petroleum which comprise the main material of producing cups, used 8kg and 18kg in polystyrene and paper production, respectively. It is noticeable that environment friendly materials are used only in paper cups, where 10m3 water and 220kg wood needed for making 1000 cups. Ultimately, the amount of electricity used in these procedures are 78 kilowatts for paper cups and 6 kilowatts for polystyrene cups.
In conclusion, paper cups are made by recycle materials,
