Speaker Simon Leake Principal Soil Scientist SESL “ The soils and vegetation of Barangaroo Headland Park”

The Barangaroo Headland Park landscape uses almost completely recycled resources to make the soils suitable for the sensitive Sydney sandstone flora and the public park turf areas. The concept was first used at Sydney’s Olympic Parklands where crushed sandstone, an abundant natural recycled resource in Sydney, was successfully used to create soil profiles for bushland regeneration.

Building on that experience the SESL Australia soil scientists came up with a concept design for the completely reconstructed soils needed for the Headland Park..

In this concept the three main materials used were:

  • Crushed sandstone originating from building excavations in Barangaroo South commercial developments
  • Recycled sand from building excavations
  • Recycled green garden waste compost (produced from “green bin” and council drop off garden waste collections)
  • Composted wood mulch screened from green garden waste collections.
