A disposable toilet bag that can be used as fertilizer!

A Swedish entrepreneur is planning to mass produce Peepoo, a biodegradable plastic bag that acts as a single-use toilet, which may help millions of urban slum dwellers in developing countries like India.

The bag, which is currently undergoing field trials in India and Kenya, is the brainchild of Anders Wilhelmson, an architect and professor in Stockholm. Once used, the bag can be knotted and buried, and a layer of urea crystals breaks down the waste into fertiliser, killing off disease-producing pathogens found in feces.

"Not only is it sanitary, they can reuse this to grow crops," Wilhelmson was quoted as saying by The New York Times. According to Wilhelmson, he has drawn inspiration to design the biodegradable toilet from Kenyan slum dwellers, who collect their excrement in a plastic bag and dispose of it by flinging it, calling it a "flyaway toilet" or a "helicopter toilet".

"People will say, it's valuable to me, but well priced," said the Swedish entrepreneur who has patented the bag and is confident that the bag will turn a profit. He plans to sell the bag for about 2 or 3 cents -- comparable to the cost of an ordinary plastic bag. According to United Nations figures, an estimated 2.6 billion people in the developing world, or about 40 percent of the earth's population, do not have access to a toilet.

It also estimated that 1.5 million children worldwide die from diarrhoea every year due to of poor sanitation and hygiene, which is largely because of open defecation of waste that contaminates drinking water.
