BLACKSBURG, Va., Aug. 20 (UPI) -- U.S. scientists are developing portable pyrolysis units that can convert poultry litter into bio-oil in a system that addresses biosecurity issues. Virginia Tech Associate Professor Foster Agblevor, who is leading the research, said the technology can convert poultry litter into three value-added byproducts -- pyrodiesel, producer gas, and fertilizer. The pyrolysis unit heats the litter until it vaporizes, the scientists said. The vapor is then condensed to produce the bio-oil and a slow-release fertilizer is recovered from the reactor. The gas can then be used to operate the pyrolysis unit, thereby making it a...
