Scientists at the Pacific Northwest National Laboratory in Richland, Washington, can turn human waste into biocrude oil, which can be refined in several types of fuel.
The team uses a process called hydrothermal liquefaction to mimic the same process that naturally produces oil in the earth.
To produce biocrude oil from human waste, the researchers need to apply high pressure and temperature to sewage, turning it into biocrude oil.
Through the process called refining, the biocrude oil is then turned into gasoline, diesel or jet fuel.
EPA (U.S. Environmental Protection Agency) says that waste water facilities in the country can provide about 34 billion gallons of sewage per day, and with the current technology, all this energy resource can be used to produce a cleaner fuel, which can be the intermediate step between fossil fuels and the green energy sources of the future.
Metro Vancouver already plans to build the first demo facility in 2018 to turn human waste into a useful energy source.
