So many coffee lovers have switched to single portion delivery devices produced by a variety of brands, including Tassimo, Flavia and Green Mountain. The coffee taste is always fresh, perfectly brewed and one doesn’t waste extra coffee left from brewing a full pot. The single dose cartridge is a composite of aluminum, plastic and coffee. Its used cartridge is currently not recyclable and is what Bill McDonough would call a “monstrous hybrid” since all three parts on their own are either compostable or recyclable, but together they make a unit that isn’t readily recyclable and thus is headed to the landfill. (The same is true for a wide range of common products too long to list here).
