The Eco-Angle on Poop

The green issue, i.e. the least green thing about toilets, and therefore poop, is water. It takes a lot of water to wash away each person's daily "production." And in a world where fresh water is in increasingly high demand ... at some point the discussion becomes, "Do we prioritize drinking water or toilet water?"
But we green folk are nothing if not inventive, so of course there are solutions. For ages, one of my favorite eco-home-porn items has been a grey water toilet. The concept is simple enough: you collect the water from showers, face-washing and tooth-brushing and use it to flush toilets instead of valuable drinking water. Two people using a grey water system can save as much as 14 gallons of water per day!
As neat as that idea is, toilet developers with green, um, brains, have branched out further, taking it into the realm of non-water toilet solutions. For example, the Huffington Post just ran a story about compostable toilets, which dehydrate and convert human waste into garden friendly fertilizer. An interesting way to make your garden grow! Perhaps the Obamas will consider something like that for the White House garden.
But wait, the ideas get even more space age: an industrial designer named Virginia Gardiner is working in London to create a waterless toilet that converts poop into energy. It uses an "anaerobic digester" to produce methane cooking gas from the poop. Which ironically would get used to cook food, which would be eaten, and then turned into waste, which would then be turned into more energy -- yeah, it's a magical closed loop energy system! Go watch her explain it in a video, it's so cool!
See? Poop talk isn't just for fifth graders anymore. It's a bona fide eco-topic! So get smart about it, and bring it up next time you're at a dinner party. People who get the green movement will be impressed with how sophisticated you are. And if there are any 5th graders around, chances are they'll be pretty impressed, too.
