composting toilet
A self-contained toilet that uses the process of aerobic decomposition (composting) to break down feces into humus and odorless gases. Advantages of a composting toilet include:
  • Water and the energy are conserved
  • Saves over 3000 gal/year compared to typical toilet; 1500 gal/year compared to a low-flush toilet
  • Turns a waste product into a valuable soil amendment, a key for sustainable agriculture
  • Nutrients and pathogens don't end up polluting waterways
  • The infrastructure is much cheaper than a conventional sewage system
