When you think about waste reduction, water saving, clean energy and repurposed materials, you probably don’t think about poo…but it’s time that you do!
SA Water has reported that a massive 90,000 tonnes of biosolids - created as a by-product from treated wastewater - is forecast to be collected for use as fertiliser from their wastewater treatment facilities this financial year.
Organic, high-quality biosolid matter helps primary producers improve soil quality and is in high demand from the state’s farming sector.
The production of biosolids is just one of the ways wastewater is reused, with one in every three litres of wastewater being used as recycled water in public parks and to supply dual-reticulation systems in housing developments across Adelaide.
SA Water are also harnessing the energy created through the biogas that is generated in the breakdown of bacteria in the treatment process. An estimated 15 gigawatts per hour of electricity is created each year, enough to meet around 80% of the electricity needs of their three major wastewater treatment plants in metropolitan Adelaide
