I could have sworn that I had posted about this before, but apparently not. National Geographic News has a new article about the Java Log, a fireplace log made from coffee grounds. Burning brighter and hotter than sawdust logs, it's better for the environment than either sawdust logs or traditional firewood. Besides recycling material that would otherwise enter the waste stream, it puts out 14 percent less CO2 than firewood and 54 percent less CO2 than sawdust logs. With Winter having bum-rushed the stage here in the SF area, I'm going to see if I can pick some of them up this weekend.
