Vineyard Post Reuse Pilot launch – towards timber circularity

A groundbreaking pilot project to reuse vineyard trellis posts has been launched in South Australia, marking a significant step towards advancing a circular economy for treated timber.

Together with Forest & Wood Products Australia (FWPA) and Wine Australia, the National Centre for Timber Durability and Design Life (NCTDDL) launched its Vineyard Post Reuse Pilot as part of the Timber Circularity Project in McLaren Vale on Monday 17 February.

The pilot is a practical trial testing how end-of-life treated vineyard posts can be recovered, processed and reused in a commercially and environmentally viable way.

The launch marks an important milestone in the ongoing collaboration between key partners Wine Australia, Forest and Wood Products Australia (FWPA), the Australian Forest Products Association (AFPA), and the University of the Sunshine Coast.

Professor Tripti Singh, Director of the NCTDDL, emphasised the importance of collaboration. “Together with our partners in both the forestry and viticulture sectors, we are developing practical pathways for the reuse of treated posts and other end-of-life timber products, demonstrating what collaboration across sectors, in research, industry and government can achieve,” Professor Singh said.

“There will not be one single recovery solution for posts. A diverse range of options from small mobile solutions to large scale technologies will be required to ensure a shift towards a net positive future,” Professor Singh added.

The pilot builds on extensive groundwork undertaken through the Timber Circularity Project, including mapping the volume and condition of unused wood resources, assessing national regulations and logistics challenges, and evaluating potential recovery solutions.

Seeking solutions for problematic waste

With additional funding from the SA Department of Primary Industries and Regions, as part of the South Australian Wine Recovery Program, the FABAL Group will undertake the pilot which features a mobile processing unit that removes fasteners such as clips, staples, and nails, then cuts the posts to size using a guillotine. This process avoids hazardous sawdust and prepares the posts for reuse as agricultural fencing or landscape timber.

Ashley Keegan, CEO of the FABAL Group, highlighted the practical benefits of the pilot. “Our goal is to convert a problematic vineyard waste stream into a product that others are willing to confidently use,” Mr. Keegan said.

The bigger picture

Preservative-treated timber and engineered wood products play a critical role in storing carbon and supporting a renewable construction future. Ensuring these products have clear and viable end-of-life pathways is essential to strengthening timber circularity. The re-use of CCA treated vineyard posts also has the potential to save the wine industry up to $3000 per hectare in disposal costs.

Professor Singh highlighted the extensive groundwork that has enabled the pilot to move forward and the importance of testing practical solutions. The pilot is one of several being planned to test other options in locations around Australia.
