Cats have toilets. Dogs have toilets. Even rats have toilets... but according to the World Toilet Organization, 2.5 billion *people* worldwide still do not have access to sanitation. Peepoo (YouTube video), developed by Swedish entrepreneur, architect and professor Anders Wilhemson, is a new biodegradable single-use toilet that could help grow crops (New York Times). A layer of urea crystals in the bag kills off disease producing pathogens and breaks the waste down... into fertilizer. If you prefer patent-free alternatives, Joseph Jenkins offers Humanure. You can get his Humanure Compost Toilet System Instruction Manual (Direct Download PDF) free of charge. All you need is a bucket, cover materials (sawdust, rice husks or coffee grounds) and the knowledge in his handbook. Peepoo or Humanure? Poo decide.

About 15% of the average American's household waste is compostable. Even apartment dwellers can turn their potato peelings and coffee grounds into gorgeous, nutrient-rich plant food with the help of worms. You can even buy the little dudes online! Once you have your worm farm set up, the big question is "Can I compost this?" You may be surprised at how often the answer is, "Yes!"
