Abstract: Wood is an excellent building material and is suitable for a wide range of residential and industrial applications. Wood is a biodegradable biopolymer and is often pressure treated to extend its useful service life. Preservative-treated wood is required for critical members and structural elements in contact with soil by the uniform building code, both nationally and internationally. However, the presence of preservatives complicates end-of-life disposal and downstream reuse of these materials because of residual metals and co-biocides. Past research has utilized wood decay fungi with inherent tolerance or resistance to metals in attempts to detoxify wood wastes (Harms et al. 2011). Ectomycorrhizal (ECM) fungi—an often overlooked but vital part of the forest ecosystem—have been shown to tolerate high levels of metal contamination.Wood is an excellent building material and is suitable for a wide range of residential and industrial applications.
