Does your office use Keurig K-Cups to brew fresh coffee one cup at a time? While they are convenient, they are also ecological disasters, since they are difficult to recycle and are wasteful. If you can't convince others to give up their K-Cup addiction, try the next best thing: Recycle them. The new Grounds to Grow On program is a mail-in recycling box that you can fill up with used K-Cups. The recycling company separates the used grinds for compost, and the other materials are used to generate energy with almost no landfill waste. Learn more at groundstogrowon.com.
