Now that the restaurant still serves coffee in a cup made of polystyrene, the material is called Styrofoam. Companies like them because they are cheaper, and customers like them because they are good for hot beverages. However, Styrofoam is one of the least environmentally friendly materials, which is blocking landfills and suffocated animals in the wild. And Styrofoam recycling is also hard to realize.
Because of the environmental detriments of the bubble, many municipalities in the country have banned the foam cups. At these locations, Dunkin 'Donuts introduced a cup made of recyclable plastic called polypropylene, which the company claims is "the best foam replacement available today."
Polypropylene is easier to recycle than polystyrene, though it is not as easily recyclable as polyethylene terephthalate or PET, the material used to make most plastic soda bottles.
Polypropylene can be identified by the number 5 appearing at the bottom of the cup. 6 represents polystyrene. PET encoded with 1.
McDonald's announced in 2013 that it will eliminate the foam cup at all American restaurants and switch to a paper cup. As early as 1990, the fast food giant abandoned foam containers.
Starbucks has given priority to putting bins in stores, but this solution can only do that. After all, many customers pick up their Starbucks cups and throw them in the trash. As of last year, about 60% of Starbucks stores have storefront ps foam cups recycling.
Although the coffee chain has been offering reusable cups, it has provided discounts to its customers, which is progressing slower than expected. Starbucks had to significantly reduce the target of 25% of its reusable drinks by 5%. Currently, only about 1.6% of Starbucks drinks are served in personal cups.
