Earlier this year, Bill Gates raised concerns about drinking pure water extracted from human waste. But Gates’s move is not about making health challenges or performing performance art, but about the quality of the Janicki Omni Processor, which is funded by the company.
The Janicki Omni Processor is a waste treatment facility that converts human waste into electricity, ash and drinking water. Developed by Janicki Bioenergy, the Janicki Omni Processor converts 14 tons of human waste into drinking water and electricity every day.
Now, the Janicki Omni Processor has begun testing in the real world. Ultimately, the system will help 2 billion people who lack adequate sanitation to remove pathogen-containing wastewater from their communities.
The Janicki Omni Processor was first tested in reality in Dakar, the capital of Senegal, where 1.2 million residents do not have sewage treatment facilities. They often use vats to clean the septic tanks and then pour them into nearby holes, creating an ideal environment for health-related diseases such as cholera and typhoid.
Mechanical emptying may be better, using trucks to transport human waste to the wastewater treatment plant. But before the arrival of the Janicki Omni Processor, Dakar had not dealt with these technologies containing pathogen waste at the sewage treatment plant.
Now, Dakar has begun to replace the sewage treatment plant with the Janicki Omni Processor, which can handle 1/3 of human feces in Dakar, while removing pathogens and making useful by-products. In addition to being able to treat sewage, the next generation of machines can also dispose of waste.
The Gates Foundation says their ultimate goal is to make the Janicki Omni Processor cheaper than hiring trucks and reduce the need for people to dispose of their own. Janicki Bioenergy piloted the Janicki Omni Processor in Dakar this spring. Gates wrote on his blog that so far, the system works as expected, but there are still problems to deal with.
Gates wrote: "The machine must be tested. Unlike computer programs, sanitary equipment cannot be tested on a Seattle table. There are a lot of variables in the real world. For example, you have to find the right person to operate the machine, you have to work with the local Government cooperation and measuring public response."
So far, the Dakar government seems to be very satisfied. But this is only the first step. Next, Janicki Bioenergy will continue to develop better machines, including making it smaller and cheaper. The Janicki Omni Processor costs $1.5 million and the commercial version sells for about $2 million to $4 million.
