A popular destination in Japan has begun receiving the first biotoilets for Mount Fuji by the non-profit organization Fujisan Club. Over 300,000 people visit the mountain annually and until the year 2000, the toilet contents were emptied down a part of the mountain.
The new biotoilets called Bianics Toilets utilize bacteria to decompose the human waste into a non-foul odor mix of water, carbon dioxide and other compounds. Decomposition begins when water is added to the waste, goes through a bacteria layer to catalyze the process, and finally goes through cedar chips for final decomposition leaving behind just CO2 and water.
Keeping up with being eco-friendly and retaining a less messy process, Mount Fuji expects to setup a seventh station prior to the next climbing season.
