For several weeks I have been using CoffeeB capsules to prepare coffee in an environmentally more friendly manner. In the process I used an old ice cream box made from cardboard to store the punctured balls of seaweed coffee.
It doesn’t smell at all, so you can keep it in your kitchen without hesitation. As the capsules decompose they dry up and the surface becames like paper or a wasp’s nest.
I have played with Dolce Gusto machines and Nespresso machines and both of them have the same flaw. They’re quick and convenient when you’re preparing coffee but less convenient when you need to get rid of the capsules. With Nespresso getting rid of the aluminium capsules is easy, once you have a container for them. You amass them at home and when you go to the recycling centre you have two wheelie bins devoted to the task of recovering the aluminium capsules and their content.
