Recycle the coffee/tea in k-cups (solid waste) in wide mouth mason jars. Mix it with compost or garden soil. Fits where the lid to a wide mouth mason jar fits. Not recommended for persons with sensitive allergies, because mold will likely form if it gets used a lot and may cause sinus congestion, emphasis on not likely. It works good at my parents house though because they don't use the Keurig that often...

A friend tested this print in his office place with a huge (half gallon) mason jar and filled it up about twice a week(!)
