Loganholme Waste Water Treatment Plant

In 2022 AWE entered in a contract with Downer Utilities Australia to design, supply and manufacture Penstocks, Stopboards and Weirs to satisfy the Loganholme WWTP Stage 8 Upgrade project.

Logan City Council has opened an innovative new facility that turns human waste into energy and fertiliser.

The $28 million biosolids gasification facility was developed by Logan City Council’s water business Logan Water.

The facility, which is the first of its kind in Australia, blasts sewage with extremely high heat to turn it into a product called biochar.

Biochar can be used for a variety of purposes including as a fertiliser for the agricultural industry. It also has potential applications in the building industry.

The gasification process destroys chemicals in biosolids such as persistent organic pollutants and micro and nano-plastics.

The project received $6 million in funding from the Australian Renewable Energy Agency (ARENA) as part of its Advancing Renewables Program.

The gasifier, at the Loganholme Wastewater Treatment Plant (LWWTP), is a centrepiece of Council’s drive towards carbon neutrality by the end of this year.

Operational cost savings and carbon credits will return almost $1 million annually to the City of Logan while a new revenue stream will be created from biochar sales.

Carbon emissions will be reduced by about 6000 tonnes a year.
