Unlike other solid-to-liquid-fuel processes such as cornstarch into ethanol, this one will accept almost any carbon-based feedstock. If a 175-pound man fell into one end , he would come out the other end as 38 pounds of oil, 7 pounds of gas, and 7 pounds of minerals, as well as 123 pounds of sterilized water. While no one plans to put people into a thermal depolymerization machine, an intimate human creation could become a prime feedstock. “There is no reason why we can’t turn sewage, including human excrement, into a glorious oil,” says engineer Terry Adams, a project consultant. So the city of Philadelphia is in discussion with Changing World Technologies to begin doing exactly that.
