If we get it right, it will be a good example of how philanthropy can provide seed money that draws bright people to work on big problems, eventually creating a self-supporting industry. The next-generation processor, more advanced than the one I saw, will handle waste from 100,000 people, producing up to 86,000 liters of potable water a day and a net 250 kw of electricity. 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.Д«efore we even started the tour, I had a question: DonвЂ™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 thereвЂ™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 doesnвЂ™t actually treat the sewage. The Omniprocessor is a safe repository for human waste. I recently went to JanickiвЂ™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 IвЂ™ve written about before.ДЄnother 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 arenвЂ™t the answer, because they require a massive infrastructure of sewer lines and treatment plants that just isnвЂ™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.

Make sure only appropriate substances are stored to minimize the risk of this happening.Why would anyone want to turn waste into drinking water and electricity?Д«ecause a shocking number of people, at least 2 billion, use latrines that arenвЂ™t properly drained. In case of an emergency or fire breaking out the cabinet is designed to hold back the fire and give people time to respond before it gets out of hand. Red cabinets are mainly used to store flammable products that must be kept away from chemicals and other substances that can act as accelerants. These pesticide COSHH cabinets are also clearly labeled with theвЂ™ hazardous to healthвЂ™ warning sign. You can find common pesticides and weed killers stored in those cabinets, as well as more specialized agriculture-related chemicals. These substances can leak gases if their containers are compromised so the cabinets need to be well ventilated to prevent the entrapment of those gases. Red and green cabinets are used for agrochemicals and pesticides. HereвЂ™s what you need to know about color-coded cabinets and what each is used for.
