Aside from the extraordinarily silly name, this seems like a very good idea:
Once used, the bag can be knotted and buried, and a layer of urea crystals breaks down the waste into fertilizer, killing off disease-producing pathogens found in feces.
The bag, called the Peepoo, is the brainchild of Anders Wilhelmson, an architect and professor in Stockholm. […]
In the developing world, an estimated 2.6 billion people, or about 40 percent of the earth’s population, do not have access to a toilet, according to United Nations figures.
They say a bag will retail for two or three cents. I wonder what the monetary value of the resulting fertilizer would be.
