I can bring this thread back to life with some confidence.
What I do with the coffee grounds is simple, my sink is one of those with a little sink in the middle. Just the right size to park a medium sized economy-plastic sieve onto a corner.
The grounds or pucks go in there then are transferred to the compost heap.
What about a knock-box, I bought a knock-box when I bought my Sylvia. I sold the Sylvia because I don't care for espresso but the knock-box has become a standard on our kitchen worktop for T-bags and the occasional puck from a Moka pot.
Get a nice stylish knock-box from Happy-Donkey. This one is fantastic and quality.
