Addio usa e getta, Starbucks sperimenta il vuoto a rendere (Goodbye disposable cups, Starbucks experiences returnable cups)

About 7 billion cups are thrown away in Starbucks cafes every year. The company has been around for some time trying to encourage the use of reusable mugs. The American brand, in fact, is conducting around twenty different tests in eight world markets. The target is to identify the best way to say goodbye to disposable cups and halve by 2030 C02 emissions.
