While this is true, it's worth noting that recycling is not the preferred step in eco consumerism. Refuse, reduce, reuse, recycle, compost. Nespresso pods cannot be reused, unless someone has hacked a kludge for that, and I doubt the recycling process composts the grounds (more info on that would be great). Extracting aluminium from its ore is hugely energy-consuming. So the most sensible thing to do is simply not use Nespresso, and avoid contributing to the aluminium problem.

There are Nespresso-compatible pods made by third parties, but they tend to be plastic. I'm unconvinced that these can be effectively recycled.

FWIW, before my landlord bought a fancy-pants bean grinding espresso machine, I'd use a stove-top espresso maker. A mokka/mukka, spelling varies. 3 mins to make a perfect espresso from grounds, and I could compost the grounds.
