Origin set to significantly increase coal ash recycling at Eraring
Origin has reached an agreement that will see 900,000 tonnes of coal ash from the Eraring Power Station supplied to Glencore to help rehabilitate the tailings dam at its Teralba mine site.
The deal is expected to almost double Origin’s Eraring ash recycling program and will be a key aspect in progressing towards our goal to recycle 80 per cent of Eraring’s ash.
Ash will be supplied over a two-year period which is expected to commence in July 2021. Trucks will deliver the ash using the private Eraring haul road, which will limit truck movements along public roads.
Executive General Manager, Energy Supply & Operations Greg Jarvis said, “This agreement with Glencore delivers great outcomes for the environment and community. Not only is Origin significantly increasing our recycling, ash from Eraring will be used to help rehabilitate the land at Glencore’s site.
“The Eraring ash dam coal ash order and exemption were issued by the NSW EPA in 2020 following extensive analysis of the ash to demonstrate it was suitable for the proposed purpose and allows us to extract coal ash from the Eraring ash dam, enabling the use of the facility as a resource.
“We already recycle around 35 per cent of the ash from Eraring for use in industrial and construction sectors and this new deal will help us substantially increase our ash recycling levels at Eraring over the term of the supply,” Mr Jarvis said.
A trial conducted in 2020 found that coal ash from the Eraring ash dam would enable Glencore to cap its Teralba mine tailings dam. Glencore has since worked with Origin, specialist consultants and regulators to build appropriate safeguards and secure the required environmental approvals for this work. The project is expected to bring forward final rehabilitation of the tailings dam by at least 10 years.
Eraring is Australia’s largest power station, supplying around a quarter of NSW’s energy needs and is Origin’s only coal-fired generator.
