Waste

Ash disposed onsite, which is the largest of AGL's waste streams, decreased 3% in FY25. There was a 2% decrease at Bayswater Power Station and a 21% decrease at AGL Loy Yang which aligns with a 10% reduction in coal combustion.

Bottom ash recycled offsite at Bayswater Power Station was incorrectly reported as ash recycled onsite in FY23 and FY24. Combined bottom ash and fly ash recycled decreased 52% compared to FY24. There was no bottom ash recycled in FY25 at Bayswater in FY25 as it was required on site.

Hazardous waste disposed increased 37% compared to FY24, mainly driven by an increase in hazardous waste disposed at Silver Springs Gas Project.

Hazardous waste recycled decreased 46% compared to FY24. The decrease was mainly driven by a decrease in decomissioning activities at Liddell Power Station and Torrens Island Power Station.

Non-hazardous waste disposed increased 20% compared to FY24. AGL Loy Yang was the main contributer of non-hazardous waste disposed.

Non-hazardous waste recycled decreased 40% compared to FY24. Despsite a 361% increase in non-hazardous waste recycled at AGL Loy Yang, an overall decrease was driven by the Camden Gas Project due to the decrease in decomissioning activities compared with the year before.

Notes

For the purposes of this data set, AGL Torrens comprises the Torrens Island Power Station and the Barker Inlet Power Station.

AGL is focused on minimising waste generation and managing waste in accordance with the waste management hierarchy of ‘avoidance, resource recovery, disposal’. AGL’s Waste Standard and Waste Standard Methodology applies to AGL controlled sites where waste is generated, and covers all waste management activities including waste segregation, storage, transportation, reuse, recycling, treatment or disposal carried out by AGL employees and contractors. The Waste Standard has 16 minimum controls to ensure that: potential risks from waste management activities (e.g., waste transportation, treatment, and disposal) to the environment and human health are minimised to as low as reasonably practicable; generation of waste is managed and minimised as far as practicable and in accordance with the waste management hierarchy, relevant legislation, and approvals; and regulatory licence conditions and other compliance obligations with respect to the management of waste are met. The Waste Standard Methodology provides guidance on how to achieve the Waste Standard minimum controls.

Unless otherwise indicated, waste categorised as 'disposed' and 'recycled' refer to waste taken offsite for these purposes.

AGL Loy Yang manages the disposal of its own fly ash (non-hazardous waste) as well as the fly ash produced by the neighbouring Loy Yang B Power Station. Figures reported above include two-thirds of the amount of fly ash disposed by AGL Loy Yang, which is the best estimate of the proportion of fly ash originating from AGL’s power generation activities at AGL Loy Yang.
