Carbon-based preservatives are susceptible to biological degradation whereas metal-based preservatives can only be chelated by fungal metabolites. While biodegradation may prove a disadvantage in long-term preservation of wood, recycling treated wood through bioremediation will recover value from end-of-service- life wood, and enhance the perception of wood as a sustainable building material. An experiment was designed to determine whether bioremediation of treated wood could degrade the wood preservative, leaving no residual contamination. The proposed research included an accelerated exposure of treated wood to mimic end-of-service-life preservative concentrations, followed by inoculation of the weathered wood with fungi. However, after one year of accelerated exposure, preservative concentrations were not sufficiently low to proceed to the bioremediation phase.
