News Review A household in Antananarivo, Madagascar, with their new Loowatt, which disposes of waste without water. No-flush REVOLOOTION E ELEONORE Rartjaras- oaniony — a 47-year-old mother, daughter and small- shop owner in Madagascar’s capital Antananarivo — stands in the middle of her yard, watching two young men in colourful overalls and rubber boots service her new waterless ‘Loowatt’ toi- let, which replaced her pit latrine a few months ago. At her feet, long-legged chickens flocked by a bunch of fluffy chicks peck at any- thing remotely resembling food, including my shoes. “My family of four uses it, and so do my three Traditional flush toilets aren’t an option in many parts of the world, but neither is leaving millions at risk of life-threatening disease.

There are reasons for this expression of grati- tude. Like all Malagasy mothers, she is terrified that her young children may one day fall into one of the many latrines across Antananarivo and literally drown in shit. Latrines aren’t a hygienic solution to the human waste prob- lem and not only because they smell and are hard to keep clean. Madagascar has so much groundwater that many Antananarivo residents grow rice in their yards. When torrential rains hit, everything floods. The waste from latrines rises and floats into the yards, houses, shops and streets bringing with it all the dark menace of disease. A waterless toilet Lack of toilets is not a prob- lem unique to Madagas- car. The WHO estimates that 2.4 billion people lack access to basic toilet facili- ties, and nearly one billion can’t even do their busi- ness in private, practising so-called ‘open defecation’, resorting to fields, street gutters or creeks. Many countries, primar- ily in sub-Saharan Africa and South Asia, face simi- lar sanitation challenges, says Professor Francis de los Reyes at North Caro- lina State University, who designs sanitation manage- ment solutions for develop- ing counties. That’s why Loowatt, a London-based startup, came up with a radically different flushing solution — one that doesn’t use water at all. In their basic appear- ance, Loowatt toilets don’t look much different from our Western dunnies, with their plastic seats and flush- ing handles, which come in the form of a pedal or a rope you pull. But instead of releasing a swirl of water into the basin, this move activates the white biode- gradable film that envelopes ONCE FULL, THE BAG IS REPLACED BY A SERVICE TEAM, AND THE WASTE IS BROUGHT (
