CIRCULAR ECONOMY DEMANDS


STEPPING UP TO


Andy Hodge, marketing director at Arxada Wood Protection (EMEA) explains how the wood preservation industry is working to support the ambitions for a circular economy


In the UK there is a clear commitment to increasing productive forestry and championing the use of timber. For softwood species to excel in service, effective chemical wood preservation is a key requirement. In this article I explore how the wood preservation industry is working to support the ambitions for a circular economy and a more sustainable, low-carbon future as set out by the Timber in Construction (TiC) Roadmap. Additionally, I highlight how poorly treated timber products are deflecting the spotlight from this, emphasising the need for change for the future credibility of the industry.


PROPELLING RECYCLABILITY AND REUSE


Industrial wood preservatives extend the service life of timber species that are not naturally durable, such as spruce and pine, enabling carbon to be locked up in the treated timber product much longer than an untreated product. Historically the sticking point has been the reuse and recyclability of the treated wood at end of life. Waste regulations are complex and take into account timber density and the amount of preservative in the treated wood.

The wood preservative industry has collectively worked hard to propel recyclability and reuse of treated wood at end-of-life, with many wood preservative manufacturers committed to the integration
