In other words, it powers itself, with electricity to spare. Through the ingenious use of a steam engine, it produces more than enough energy to burn the next batch of waste. That means they use a lot of energy, which makes them impractical in most poor countries. Others burn it using diesel or some other fuel that they buy. government.īefore we even started the tour, I had a question: Don’t modern sewage plants already incinerate waste? I learned that some just turn the waste into solids that are stored in the desert. The machine runs at such a high temperature (1000 degrees Celsius) that there’s no nasty smell in fact it meets all the emissions standards set by the U.S. If they took it to the Omniprocessor instead, it would be burned safely. Either way, it often ends up in the water supply. Today, in many places without modern sewage systems, truckers take the waste from latrines and dump it into the nearest river or the ocean-or at a treatment facility that doesn’t actually treat the sewage. The Omniprocessor is a safe repository for human waste. I recently went to Janicki’s headquarters to check out an Omniprocessor before the start of a pilot project in Senegal. The project is called the Omniprocessor, and it was designed and built by Janicki Bioenergy, an engineering firm based north of Seattle. One idea is to reinvent the toilet, which I’ve written about before.Īnother idea-and the goal of the project I toured-is to reinvent the sewage treatment plant. So a few years ago our foundation put out a call for new solution. Western toilets aren’t the answer, because they require a massive infrastructure of sewer lines and treatment plants that just isn’t feasible in many poor countries. If we can develop safe, affordable ways to get rid of human waste, we can prevent many of those deaths and help more children grow up healthy. The waste contaminates drinking water for millions of people, with horrific consequences: Diseases caused by poor sanitation kill some 700,000 children every year, and they prevent many more from fully developing mentally and physically. Why would anyone want to turn waste into drinking water and electricity?īecause a shocking number of people, at least 2 billion, use latrines that aren’t properly drained.
