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
