Abstract
Wood has many positive environmental attributes including excellent physical and mechanical properties, reduced energy requirements for processing, and the ability to sequester carbon. Wood is also susceptible to biodegradation under proper conditions. Preservative treatment markedly reduces the risk of degradation but many chemicals used for wood protection can pose a disposal challenge at end-of-life. Identifying options for reuse/recycling of treated timber is essential for ensuring the timber remains in use without causing negative impact. This paper reviews challenges and opportunities associated with treated timber at end-of-life from an Australian perspective and outlines potential options for reuse, recycling and disposal of wood treated for residential and industrial applications. While there exists options for reuse and disposal, most are currently not economically or logistically feasible.
