Scentre Group reports on whole building waste generation, which includes waste generated by construction and development activities and waste generated by tenants and visitors.
In 2015, the Group’s shopping centres disposed of 48,256 tonnes of general waste to landfill and and our design and construction activities an estimated 136,953 tonnes of landfilled waste.
We are looking at ways to minimise the amount of operational and construction waste ending up in landfill and we continue to divert large amount of recyclable materials including concrete, metals, cardboard, plastics and organics to specialised waste recycling facilities.

Across the Australian portfolio our centres have managed to divert 47% of waste generated on site to recycling waste streams. Some waste streams in particular have seen a steady increase in volumes collected since 2014 including cardboard, organics (producing natural fertiliser) and cooking oil (ending into biofuel) as a result of our recycling efforts. This consistent improvement is a great outcome for the environment.

* Scentre Group used the guidance provided by GRI-G4 Global Reporting Initiative Implementation Manual to report on waste. Scentre Group reports on
whole building waste generation, which includes waste generated by our tenants, with the exception of major tenants, who report separately on their
generated waste.
Design & Construction waste volumes were estimated based on information provided by contractors from the Pacific Fair (QLD) & Warringah (NSW)
projects. Data was extrapolated for the top 10 major projects by spend, based on the average quantity of waste generated per project per dollar, by state.
Where no state level DD&C information was available, an average of the two states was applied. In 2015 we have amended our approach to estimating
waste amounts from construction projects. Up until 2014 reporting year, construction waste was estimated based on the Sydney City project which was
completed in 2010. This project was one of a kind with significant amount of material excavated from the site. This project no longer represented the nature
of our current projects and therefore was considered to be an outdated baseline for extrapolation of waste volumes for other projects. Scentre Group
continues to review its approach to estimating waste from DD&C.
