Disposable Toilet Could Help Fertilize Crops

According to The Global Water Supply and Sanitation Assessment 2000 by the World Health Organization, 40% of the global population does not have access to proper toilets, mostly in Asia and Africa.

The disposal of human waste is a problem in developing countries where those who do not have the privilege of a toilet simply answer nature's call outdoors. People defecating in the open is not an uncommon sight in India and this waste seeping into the ground poses a major health risk as it can contaminate drinking water.

Anders Wilhelmson, an architect and professor in Stockholm, saw slum dwellers in Kenya simply defecating in a plastic bag and flinging it into open spaces not bothering about where they land. While this does sound disturbing, it gave Wilhelmson an idea.

He has developed and is trying to market a single-use biodegradable plastic bag that once used can be knotted and buried. A layer of urea crystals breaks down the waste killing the disease-producing germs found in excreta and making it a fertilizer that can be used to grow crops.

Calling the bag Peepoo Wilhelmson is looking to sell this "green" alternative at a cost of 2-3 cents per bag, about a rupee.

The Restroom Association of Singapore (RAS) was established by Jack Simm in 1998 to break the taboo of toilet and sanitation and legitimize it for mainstream culture. In 2001, he founded the World Toilet Organization (WTO).
