Diversion from landfill
Construction and demolition waste represent one third of all waste sent to landfill in NSW. JHCPB’s efforts focus on reducing the Project’s contribution to landfill by recovering and reusing waste materials (on site and off site) as much as practicable.
From the commencement of construction to March 2021, JHCPB has diverted 21,866.38 m3 of construction waste from landfill (90%) and reused 4,207,883 tonnes of spoil (97%). Project spoil has been beneficially reused on site for civil works and at various approved offsite reuse sites, such as the Northern Roads Project and Western Sydney Airport. Annual waste to destination audits are also conducted for all waste streams.
JHCPB are currently exceeding both construction and spoil diversion targets but the Project’s office waste diversion is performing under the target. The spoil diversion performance graph below reflects suboptimal performance against IS V1.2 Was-2- Level 2 (40%- 60%). As outlined in the previous annual review, focus during 2020-2021 was set on improving the office waste performance against the target through implementation of a Project Wide Waste Strategy.
The below actions were completed as part of the strategy implementation:
JHCPB is currently investigating the use of recycled materials in concrete. These include:
