Coffee capsules from Nespresso and other brands are made out of aluminium, right? So what could be more useful than to produce even more coffee capsules made out of secondary aluminium? Hmm, it is hard to believe, that I’m the first one to come up with that idea. There might be a catch to it. But if it isn’t possible (or allowed) to make coffee capsules out of secondary aluminium, doesn’t that automatically mean that all future coffee capsules will be made out of newly extracted primary aluminium? Wouldn’t that mean, that it is just impossible to make coffee capsules in an eco-friendly fashion?
