Keurig's new K-Rounds coffee pods are plastic-free and could finally make single-serve coffee-making sustainable ( www.techradar.com )
This is quite exciting in that it removes plastic waste. I see no reason why different companies can't make different shape ones to maintain their lock-in. I expect a knock-off market to pop-up, but that exists with plastic pods too. It's a step in the right direction at least.
