But to make a cup the plastic needs to be melted, put in a form and cooled. This process requires a lot of water. Most of it is reused. But at least half a liter goes away.
The production of disposable cups consumes 500 ml of water, while washing in the sink uses 400 ml, as estimated by the Federal Institute of Education Science and Technology (IFSP) Itapetininga. Washing in the machine is even more economical and spends only 100 ml per cup, ie only 20% of what is spent to produce a plastic cup.
The most popular cups on the market have a capacity of 200 ml of plastic and cost R$ 0.02. The 300 ml, which costs R$ 0.04, is the size most similar to the glass used at home. The firmer plastic cup, the crystal, costs R$ 0.16 cents each.
For those who are experiencing a lack of dishwasher water, buying may be the solution right now. In the long term, it can contribute to further undermining supply.
Good Morning Sao Paulo has already shown establishments in Vila Mariana, in the South Zone, and Vila Madalena, bohemian neighborhood of the West Zone, have already adopted plastic cups. Some consumers do not get used to it and even carry their own glass for the toast.
