If customers take the cups home, they can also take advantage of Starbucks’ partnership with Ridwell, a company that will collect reusable cups at home. Each cup is then cleaned and sanitized and put back in rotation for another customer to use.
The traditional hot disposable cups of the hammock are made of plastic and paper, so they are difficult to recycle. And while compostable cups can be a more environmentally friendly option, they need to be composted in an industrial facility. Therefore, reusable cups can be a more practical ecological choice, although this approach can be difficult to scale.
Starbucks launched a reusable cup test at London Gatwick Airport in 2019, a year after the company launched the NextGen Cup Challenge in collaboration with McDonald’s and other partners to rethink cup materials. Competitors, from amateurs to industrial design firms, submitted proposals for cups made from mushrooms, rice husks, water lilies, corn leaves and artificial spider silk.
