vineyard post

The current and projected availability of end-of-life treated-timber vineyard posts in Australia has been assessed and mapped to enhance timber recycling and reuse potential by improving the visibility oftimber flows. While timber provides benefits such as low embodied carbon and renewability, chemically treated variants present significant challenges for reuse and recycling. This study addresses these barriers and aims to develop circular economy pathways for preservative-treated timber products in Australia, ultimately reducing the amount of timber sent to landfill. Data were collected through industry site visits, surveys, and publicly available sources. The inclusion of councils with existing circular economy strategies highlights regions that could develop into circular economy hubs, supporting new business opportunities. This map helps identify resource distribution, infrastructure, and regulatory constraints, enabling informed decision-making and fostering stakeholder collaboration.
