A:Answer Rosie, I bought the Nespresso package deal with a free recycle mail-in bag and have wondered about the same question. I make use of reusable capsules for my Keurig to eliminate the single use, multi-material, non-reusable capsules used in that machine. I found at least one reference online to "Refillable Nespresso Capsules & Pods", however, I have not bought or tried them myself, so can not offer an opinion. I do find some comfort in that the Nespresso capsules are 100% aluminum (other than the coffee) and recyclable. Since espresso is a high pressure coffee maker, I understand the need for a pressure capsule like the Nespresso aluminum pods, and would have to be confident that a reusable pod would supply the necessary pressure integrity to perform correctly. Sorry I can't share first hand experience.
