The production of Peepoople bags is being subsidized by its creator, Anders Wilhelmson, but this brilliant idea could become completely self-funding once it catches on more in developing countries. The bags currently cost users 3.4¢. FastCompany writes:
For less than four cents a bag, Peepoople’s mobile toilet takes dangerous waste and turns it into valuable fertilizer. Peepoople makes bags for going to the toilet, but not any old bags. Inside are chemicals that break down the poo and pee into fertilizer. Peepoople’s bags not only help contain dangerous waste, offering alternative sanitation in slums and refugee camps. They also begin to turn the feces into a positive material that can nourish crops.
The business was started 10 years ago by Anders Wilhelmson, an architect, urban planner, and professor at Sweden’s Royal Institute of Technology … (who) started to think of the bag – which he considers a sort of mobile toilet, something akin to what a cell phone is to a landline.
