As you already know, I’m a big fan of coffee. Since it’s something I consume to excess, I do try to be aware of limiting my impact by buying locally roasted, organic, and fair trade beans. My other secret green coffee weapon is, very simply, to employ a reusable filter.
I use a gold filter that was a hand-me-down from my parents (lowering my impact even more!), but if you’re in the market for one, they cost around $15. If you’re worried about time, I would estimate that dumping my grounds in the compost and giving the filter a quick rinse takes pretty close to the same amount of time it would to compost a disposable and then pull a new one from the box.
Looking for another opinion? I found this relevant, albeit somewhat dated, conversation on Apartment Therapy.
Give it some thought over your next cup.
