Feasibility study for a CCA vineyard post aggregation site

This feasibility study evaluates the viability of establishing dedicated aggregation sites in South Australia for discarded chromated copper arsenate (CCA)-treated vineyard posts. 

It examines environmental, health, safety, and economic risks posed by uncontrolled stockpiling or improper disposal, including contamination, fire hazards, and regulatory non-compliance.

More than 500 potential sites in South Australia were assessed, with 15 high-potential locations shortlisted across 5 key wine regions, with a focus on the Riverland and Limestone Coast. Three operational models were considered, with the co-location of an aggregation site at an existing waste facility (Brownfield Site with Existing Operations) identified as the most cost-effective and feasible option due to its low capital cost, faster implementation, and existing infrastructure.
