Children play near open drainage of sewers in Nairobi, Kenya’s Kibera slum, underscoring the urgency of improved sanitation options in crowded Third World periurban settings.

Three African social entrepreneurs, David Kuria, Joseph Adelegan and Trevor Mulaudzi, spoke at the National Press Club in Washington, D.C., in February to share this revolutionary approach to solving the global sanitation crisis. The entrepreneurs speak from experience; each has established lucrative and groundbreaking businesses related to people “doing their business” — and providing the proper sanitation facilities for it often in crowded urban centers of Africa and their periurban suburbs. Their business models, once considered distractions in the traditional policy or charity realm, are proving to be successful ventures. Their innovations are successfully shifting social behavior and improving public health, the environment and the economy. Trevor Mulaudzi, a South African entrepreneur, stressed that “no one wants to use a dirty toilet no matter how poor they are.”
Nairobi entrepreneur David Kuria is making the toilet a hot commodity in Kibera, one of the largest slums in Kenya. To increase demand for and maintenance of toilets in the slums, he founded a venture called Ecotact. “Why just do two quick things in the toilet?” Kuria asks. Ecotact builds “toilet malls” that provide bathroom facilities along with shoe shines, food, phone booths and other commercial services.
Each toilet complex is equipped with eight toilets, a water kiosk, a baby changing station and gender separate showers. About 30,000 customers use Ecotact’s facilities every day. Corporations now vie for advertising, while the nearby vendors strive to keep the toilets clean. And it’s the business model, not charity or education alone, that drives this success.
Lately, the toilet malls have been attracting unlikely champions — a popular comedian who does a stand–up sketch about toilets, the country’s beauty queen Miss Kenya, and the nation’s Vice President Kalonzo Musyoka himself, who recently stopped in to use the facilities and pose for photos. In a continent where more than six out of every 10 people don’t have a sanitary toilet, this new service is removing the taboo around human waste, creating jobs, improving self esteem and making communities enthusiastic about hygiene.
Kuria has recently won several international awards for his work. He’s collaborating with Ashoka, Rotary, Global Water Challenge, the Acumen Fund and other social entrepreneurs internationally to scale up his model and combine it with similar innovations. There’s promise for it to extend throughout Kenya and the rest of Africa.
For Nigerian entrepreneur Dr. Joseph Adelegan, a civil engineer by training, human and animal waste wasn’t waste but an opportunity that shouldn’t be wasted. A nearby slaughterhouse had been disposing daily the waste of 1,000 slaughtered cows directly into a local river. Dr. Adelegan designed a bioreactor that digests the waste into biogas that generates electricity and is used for cooking fuel. Local women’s organizations sell the fuel at affordable prices for urban poor. The solid waste left over is a cheap and effective fertilizer. His models, named “Cows to Kilowatts” and “Power to the Poor,” also reduce emission of methane gas, a potent greenhouse gas. His initiative also has improved the quality of the water that the local community uses for cleaning and bathing.
The successful business model not only tackles the technological aspects of this problem, but — even more powerfully — it has mobilized the community. It has even stirred the Nigerian government, which used to block such initiatives, into action. In 2008, Dr. Adelegan’s model was accepted into national policy and will be replicated within other slaughterhouses in Nigeria. Meanwhile, he has also been featured on CNN, awarded prizes from the World Economic Forum and covered recently in Fortune magazine. He’s now working with other social entrepreneurs to extend the approach to other African countries.
