“…As they are very harmful, checking of their elimination at the end of the bio-treatment is really important. Table 1 GC-MS analysis data for PAH and oxy-derivatives in the examined wood samples before (T 0 ) and after mycelium growth T 0 = CTW before mycelium treatment; T 1 A = 33% mixture of CTW-WS (sample A) after mycelium growth for 44 days (T 1 ); T 2 B = 50% mixture of CTW-WS (sample B) after mycelium growth for 60 days (T 2 ); T 2 C = T 1 A with an addition of CTW up to an overall content of 60% (sample C), after 60 days (T 2 ) of mycelium growth As demonstrated in previous works, methanol extraction is a good system for both phenols (Becker et al 2002) and PAH (Portier et al 1996) desorption from CTW. In the sample preparation for cryo-milling, necessary to homogenize samples and disrupt fibres, an excess of water must be avoided, as the frozen mass would have a vitreous consistence, hampering the milling process.…”

A bioremediation system for creosote-treated wood is proposed, based on the detoxifying capability of Pleurotus ostreatus, a ligninolythic fungus. Non-sterilized chipped contaminated wood was mixed at various ratios with wheat straw on which Pleurotus mycelia was grown. At 1:2 initial ratio contaminated wood:wheat straw, chemical analyses demonstrated an almost complete degradation of creosote oil components after 44 days, also confirmed by a significant reduction of ecotoxicity. Lower ratios, i.e. higher amount of contaminated wood, lower system efficiency, although a better creosote degradation was obtained by a stepped up wood addition.

“…Although the literature suggests that bacteria do not achieve high efficiency in the removal process of Cr, it has a remarkable effect on creosote and PCP (Portier and Miles 1996). Chemical and biological methods were performed.…”

This manuscript provides a brief review about chemical and biological agents used to bioremediate treated wood waste. Wood preservatives have been used to increase wood’s useful life, because any species is subject to decay. Studies indicate that the disposal of treated wood after its service has drawn concern and scrutiny. Practices have included disposal in landfills or construction sites as well as destruction by burning, so it is apparent that more environmentally friendly options are needed. To mitigate these problems, acidic agents, fungi, and bacteria can be used as alternatives to remove heavy metals. At optimum temperature and concentration, acids play a major role in the removal process. The process is enhanced when a bioremediation technique is used after chemical extraction. In fact, bioremediation has been shown to be a remarkable technique for recovering copper, arsenic, creosote, and other compounds. The major drawback is the extensive duration of fungal activity for release of heavy metals.

“…Efficiencies of such treatments are in the range of 98-99% of creosote removal (Catallo & Shupe 2003, Shupe et al 2006. Further bio-polishing with microbial consortia (such as mixtures of strains from the bacterial genera Pseudomonas, Flavobaterium and Acinetobacter strains) is possible (Portier et al 1996). All in all, taking in opportunity-costs such as for purification and other processing, incineration with co-generation of energy is however an easier and more eco-friendly solution for decommissioned creosote-containing wood (Werner et al 2007).…”
