Octowood, part of the Rundvirke Industrier AB Group, has invested in a new Tanasote treatment plant to offer an additional choice of long-term wood protection to their fencing and powerline customers.

This is a significant commitment by one of the leading creosote treaters in Europe to offer a modern wood protection technology to propel sustainability through the heart of its operations.

An innovative copper-oil wood preservative, Tanasote was developed by Arxada as a modern alternative to creosote. Protecting against a wide spectrum of decay fungi, it has been specifically designed to minimise early failures while providing a long service life. A combination of organic biocides and copper in a mobile oil formulation, Tanasote achieves a high penetration depth into the timbers, providing excellent water repellent properties for improved stability in service.

Renowned for innovation in the agricultural fencing sector with its Octopost range, sustainability and quality are the key drivers for Octowood investing in Tanasote copper-oil. Leif Berglund, Octowood’s Tanasote Project Director and acting board member commented, “Sustainability requirements and environmental aspects are crucial today. We have to keep up not only because of legal requirements for our business, but a desire to find new ways to produce as sustainably as we can.

The challenge for Octowood is to impregnate our carefully sourced pine to give it a long shelf life. After assessing extensive efficacy test data, including equestrian fencing trials, and reviewing the BPR risk assessments reports, we are confident that Tanasote copperoil is the best long-term option. With it obtaining the maximum authorisation period before reauthorisation under BPR, we know it’s a wood preservative that is worth the significant investment to ensure we achieve quality in our treated wood with minimal impact on the environment.”

To date, Tanasote has been granted Biocidal Products Regulation (BPR) authorisation for use as an industrial wood preservative for Use Classes 3 and 4 in 23 countries across Europe.
