Yeah, I've even bought compostable and refillable pods for friends who own Nespresso machines so they can try them out but they always go back to the aluminium ones. What percentage of total pods used are niche manufactured and environmentally friendly? I think the big issue is the prevalence of them in almost every office and client room now.. I've seen entire bins filled with pods in a single day for just one floor. Nobody is accountable or even notices. 300,000,000 are used in the U.K annually.
I'd never heard of ESE pods before. Couldn't someone just use a calibrated tamper? I would have thought that and a basic grinder would make much nicer espresso. Arghhh.
