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.
I was surprised to learn that the store brand k-cups around here are already fully compostable. It’s just a biodegradable plastic ring with half a sphere of coffee filter on the bottom and a paper disc on top.
i imagine “biodegradable” plastics are the things that we’re finding down in deep sediment layers where they shouldn’t be; the ones that aren’t biodegradable don’t fall apart hard enough to hitch rides in water droplets.
I’d bet millions of dollars on the proposition that we don’t know the answer to that question yet, if I had it.
