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.
Basically, a single dose of coffee, wrapped, and sealed in traditional coffee filter material, which is inserted into the machine,can be thrown in to the compost.
So I’m learning that the Keurig isn’t even innovative. Shame!
