If customers take the cup home, they can also take advantage of Starbucks’ partnership with Ridwell, a company that will collect the reusable cups from your home. Each cup is then cleaned and purified and placed back in the rotation for another customer to use.
The traditional, disposable, hot cups of the necklace are made of plastic and paper, so it is difficult to recycle. And while compostable cups may be a greener option, they should be composted in an industrial facility. Thus, reusable cups can be a more practical eco-friendly choice, although this approach can be difficult to scale.
Starbucks launched a reusable cup trial at London’s Gatwick Airport in 2019, a year after the company launched the NextGen Cup Challenge in partnership with McDonald’s and other partners to reconsider the cup material. Participants ranging from amateurs to industrial design firms submitted suggestions for cups made from mushrooms, rice husks, water lily cubes, corn leaves and artificial spider.
