Industrial strength sewage sludge dryers weighing 34 tonnes on their way to Loganholme Wastewater Treatment Plant from Germany's Black Forest region

A pair of 34 tonne sewage sludge dryers built in Germany's Black Forest are on their way to Logan.

The industrial strength dryers will be integral parts of the bio gasification facility turning human waste into energy at the Loganholme Wastewater Treatment Plant.

Logan commissioned Dutch company ELIQUO to build the dryers at its German factory after being unable to find an Australian company with the expertise to produce the appliances.

It took nearly five months to build the dryers, which are larger than a shipping container at 18 metres long and 3.5 metres wide.

They were then trucked through the narrow streets of Bonndorf in southwest Germany, to port.

They are being shipped to Australia and should arrive in Logan in August for assembly.

Infrastructure chair, Councillor Teresa Lane, said the dryers were another mind-boggling component of the Loganholme Biosolids Gasification Project.

"Council has been looking at emerging technology as part of the project since officers first drew up plans to build the gasifier," Cr Lane said.

"I think it's great they are pushing the boundaries on emerging environmental and innovative ideas that save residents money in the long run.

"The dryers are an engineering feat given their size and the challenges posed by testing and transporting them during COVID-19.

"Once they arrive in our city, they will be assembled along with the many other components required to bring the gasifier online.

"This is an Australian-first and I'm confident we will achieve great outcomes for all the hard work put in."

Council, along with project partners Pyrocal and Downer, successfully trialled a process of thermally treating sewage sludge (biosolids) to produce biogas last year.

The biogas is then used as a renewable energy source as heat drying the remaining biosolids, turning it into a biochar, suitable for agricultural purposes.

The Loganholme Gasification Project is designed to reduce CO2 output by about 4800 tonnes annually and prevent organic pollutants from entering the soil.

The $17m project was made possible by a $6 million grant from the Australian Government's renewable energy agency ARENA.

It will come online mid-2022.
