Water and waste
The Group is exploring options for responsible natural resource management, which largely includes waste and water. Achieving efficient water consumption and reducing the amount of operational waste across the Group’s portfolio can help to better service stakeholders and reduce the Group’s environmental impact.
This year we implemented multiple initiatives in water and waste management under the guidance of the Board.
Initiatives
This year, we worked in partnership with an external consultancy to identify waste tracking and reporting processes for the Australian office portfolio.
By establishing a baseline, supplier reviews, cost optimisation and tenant engagement, Centuria plans on conducting NABERS waste assessments and data driven improvement strategies to efficiently manage the waste generated by assets in the long term.
The strategic plan aims to introduce the Bintracker program, where the source and weight of all waste generated on-site will be measured. This creates efficient waste collection strategies and insights into the types of waste generated that could help Centuria have more effective engagement with tenants on how best to manage their waste.
Exchange Tower and 140 St Georges Terrace, were recognised among Western Australia’s most water efficient office buildings by the Water Corporation’s Waterwise Development Program. Exchange Tower was the recipient of the ‘Platinum’ Waterwise award, which recognises one business as a leader in water efficiency, demonstrating best practice and innovation in water management for the reporting year.

Water and waste management is an important part of asset management. The ESG Management Committee oversees the systems set in place for future and current assets. Regular updates are provided to the Culture and ESG Board Committee, who then present any material information to the Board.
