Logan City Council has created an Australian-first by successfully turning human waste into energy at its high-tech Loganholme Wastewater Treatment Plant.
Council, along with project partners Pyrocal and Downer, have 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 a 'biochar', suitable for agricultural purposes.
Logan Mayor Darren Power has described the successful trial as a 'huge win' for ratepayers and the environment.
"Every day the plant sends three truckloads of treated waste to the Darling Downs to be used as a soil conditioner," Cr Power said.
"The gasification process perfected at Loganholme will reduce the volume of biosolids by 90 per cent and help our farmers.
"This will save ratepayers around $500,000 annually while significantly reducing our carbon footprint.
"Council's water business Logan Water and development partners Pyrocal and Downer deserve great credit for coming up with such an innovative solution."
The Federal Government's Australian Renewable Energy Agency (ARENA) contributed $6 million towards the $17 million project.
Infrastructure Committee Chair, Councillor Teresa Lane, said the project has attracted global interest from renewable energy companies and municipal councils.
"Using synthetic gas in this way in something that hasn't been tried before so everyone has been watching to see how it would pan out," Cr Lane said.
"To be able to say that this technique was perfected in Logan is something we can all be proud of.
"This is a game-changer for the industry and it was developed and trialled right here in Logan."
The process will reduce CO2 output by 4800 tonnes annually and prevent organic pollutants from entering the soil.
Council is exploring opportunities to market the biochar.
