Supplying around a quarter of all energy to New South Wales, Eraring is Australia’s largest power station. Greg Jarvis, Origin’s Executive General Manager, Energy Supply & Operations, shares how we’re recycling coal ash to help rehabilitate the environment.
Origin’s goal of recycling 80 per cent of the coal ash generated at our Eraring Power Station has taken a big step forward after we entered a new agreement to supply 900,000 tonnes of ash to mining company Glencore over the next two and a half years.
Coal ash from the Eraring ash dam will be supplied to Glencore to help cap its Teralba mine tailings dam. The project is expected to bring forward final rehabilitation of the tailings dam by at least 10 years. Origin’s Executive General Manager, Energy Supply & Operations Greg Jarvis said the deal with Glencore signals a shift in approach to ash recycling.
“This agreement delivers great outcomes for the environment and the community. Not only are we significantly increasing our recycling, but Eraring’s ash will also be used to help rehabilitate the land at Glencore’s site,” he said.
“The resource recovery order from the NSW Environmental Protection Authority allows us to extract coal ash from the Eraring ash dam, so we’re now starting to view this facility as more of a resource, like a quarry”.
“We currently recycle around 35 per cent of the ash from Eraring for use in industrial and construction sectors. This new deal will help substantially increase our ash recycling levels at Eraring over the term of the supply,” Mr Jarvis said.
This project follows the successful partnership with a local ash supplier to install a high-capacity classifier to extract high quality ash to be used in cement and similar industries.
