Having posted a review of the year in pee and poop in 2009, and again in 2011, it's been encouraging to see how many people are interested in what we do with our human waste.
It is, after all, a matter of huge importance for the future of humanity. (Not to mention an opportunity for some base toilet humor too!)
From pee-powered generators to pigeons that shit soap and a composting toilet scheme said to save hippos, it's been a busy year for toilet-related stories. And that's before we even get to Bill Gates' big money bet on a toilet of the future.
Here are some of our favorite posts.
