Members of the Western European Institute for Wood Preservation (WEI) have launched a strong appeal to European authorities to closely monitor implementation of their directives on creosote and arsenic compounds.

The WEI, which made the call during its annual meeting in Cannes, says different interpretations of the directive text between member states risked creating difficulties for companies operating at a European or international scale.

WEI members also want clarification on the directive on waste and the fate of treated timber after its service-life.

However, members are convinced that preservative-treated wood has a future provided its performance quality remains good and it is not a threat to the environment or human health.

The WEI will continue discussions on establishing an European quality system for preservative-treated wood, based on European standards and independent third-party control.
