The main by-product from burning coal at our sites is coal combustion products (CCPs), including fly ash, bottom ash and cenospheres. These materials are either stored on site or reused by other industries, such as in the production of concrete and building products, helping reduce reliance on natural quarry materials.

Reusing CCPs conserves natural resources, saves energy, reduces associated carbon emissions, and supports a more efficient circular economy.

In 2023/24, 15.85 per cent of our ash by-product was reused (up from 14.29 per cent in 2022/23).

Rehabilitation is a key part of responsible mining, helping ensure a positive legacy long after mining activities are complete.

At Meandu Mine, 25 kilometres south-east of Kingaroy in the South Burnett, we work closely with regulators to restore mined land to native ecosystems, using species suited to the region’s climate and conditions.

In 2023/24, more than 39.4 hectares of native ecosystem rehabilitation was completed at Meandu, bringing the total area rehabilitated since the 1980s to 704.9 hectares.

In late 2022, a long-term study began at Stanwell Power Station to explore how silvopastoral systems – combining trees and livestock grazing – can support carbon neutrality in sub-tropical and tropical farming.

Stanwell has provided land within our 100-hectare hardwood tree plantation for the project team to use.

Led by the Queensland Department of Agriculture and Fisheries and co-funded by Meat and Livestock Australia, the five-year study is generating data to inform practical tools for local cattle farmers. These tools will guide decisions on tree species, planting configurations and land use to deliver carbon and productivity benefits.

In 2023/24, Stanwell partnered with the Fitzroy Basin Association to complete creek rehabilitation works at Stony Creek – a natural waterway that runs through our Stanwell Power Station site.

The project involved reshaping and stabilising eroded creek banks to allow revegetation and reduce sediment runoff.

Supported by the Reef Trust and Great Barrier Reef Foundation, the works will help protect the Great Barrier Reef by preventing sediment from entering downstream waterways. Stanwell contributed planning, technical advice and on-the-ground support for the project.

Stanwell has partnered with Tunuba, an Indigenous business, to manage around 1,200 hectares of conservation land at Stanwell Power Station, including the Stanwell Nature Refuge.

Tunuba (named after the Darumbal word for the Fitzroy River) delivers land management services that support local employment, cultural practice and economic development in Central Queensland.

Tunuba’s rangers are working alongside ecologists to apply strategic and cultural land management techniques that enhance and protect the natural values of the site.
