Australian WWTP successfully converts human waste into energy

摘要

Logan City Council in Australia has successfully converted human waste into energy at Loganholme Wastewater Treatment Plant.Working with gasification systems provider Pyrocal and Downer Group,the council has been trialling a process that sees sewage sludge(biosolids)baked in extreme temperatures to produce biogas.The biogas is then used to heat the remaining biosolids,turning it into biochar,which can be used for agricultural purposes.Logan's Mayor Darren Power said the trial was a"huge win"for ratepayers and the environment."Every day the plant sends three truckloads of treated waste to Darling Downs to be used as a soil conditioner,"said Power.
