Waste
Ash waste disposed on-site, which is the largest of AGL's waste streams, decreased at Bayswater Power Station (down 2%), increased at Liddell Power Station (up 7%) and increased at AGL Loy Yang (up 30%). This resulted in an overall 4% increase in total ash waste disposed on-site. Ash waste recycled off-site decreased by 14% overall, arising from a 14% decrease at Bayswater Power Station and an 11% decrease at Liddell Power Station.
Hazardous waste recycled decreased 27% compared to FY21, driven by lower hazardous waste generation volumes at Torrens Island Power Station and Liddell Power Station.
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 license 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 Energy’s power generation activities at AGL Loy Yang.
FY22 ash waste disposal data for AGL Loy Yang is based on estimates only. Final ash waste disposal data will be available later in 2022.
