"converting human waste from home septic systems into phosphorus-rich fertilizer... could reduce the cost of pumping out septage by as much as 25 percent... high temperature, high-pressure process called hydrothermal carbonization (HTC)... a thermochemical conversion technique that can transform wet biomass into energy and chemicals without pre-drying... a mobile unit that can pick up the waste, convert it to fertilizer and then move on to the next house"
