Keurig, the company that got us all hooked on single-serve coffee systems and has helped us churn through billions of plastic throwaway K-cups, just reinvented its single-serve system in what may be the most sustainable way: K-Rounds.
K-Rounds are plastic and aluminum-free, highly-compressed coffee ground pods held together by an ultra-thin layer of plant-based material (alginate). As one Keurig exec described it, "It’s just coffee in those pods."
