At least in NA, it's either through Nestle facilities or via community recycling facilities. Each order comes with bags for either mail-in (red bags), recycling bin (green bags), or store drop off (I believe black bags).
Coffee grounds is also bio degradable.
I don't really understand the need for the pods. Coffee is best fresh roasted and freshly grinded, which the ones in pods are absolutely not. Once i saw an ad where they sold "vintage coffee" nice rebranding to sell old ass pods, this isn't wine.
Then they made these coffee balls that fit in a new machine, what are you doing?? Instead ob buying beans and grind them in your machine that can grind all the coffee, people rather buy some pre-ground weird ass coffee balls?
Some people don't care about the flavor of their coffee, only how much of a buzz it can give them and how quickly. Either that or they've been conditioned by Starbucks marketing to think that stale, burned coffee actually tastes good.
