“…Borates have also proved to be an efficient ingredient for dual protection. Lloyd et al (2018) studied the application of dual borate and CuN treatment of timber bridges. The authors pointed out that the addition of borate to protect heartwood provided significant increase in bridge tie useful life, therefore it can be used either with creosote or copper naphthenate.…”

The wood preservation industry has taken large leaps to develop and produce chemicals that protect wood from microorganisms and weathering degradation with no or low environmental impact. These improvements occurred after concerns of federal and public agencies about the release of toxic components into atmosphere, soil, and water. These days, reduction in use of non-renewable resources is a crucial concern. Wood and wood-based products are generally low in CO2 emissions and can be gained from sustainable forest resources. Therefore, they can play a significant role as renewable resources. In comparison to other building materials, wood has numerous advantages, such as suitable thermal insulation, high strength to weight ratio, easy machinability, and attractive esthetics. Wood as a valuable building and industrial material requires to be protected due to its biodegradable properties especially when it is submitted to harsh conditions. Wood durability can be improved through wood protection which include wood preservatives and modification systems. Wood protection should be safe to use, efficient, cost-effective, permanent, and should not corrode metal or degrade wood components. Numerous reviews of wood protection can be found in the scientific literatures, but until now a review of a combination of wood preservation and wood modification has not been studied. It should be considered that the latest research projects in wood protection in academia not always reflect the most current developments in the industry due to exclusive rights. The findings reported in academia contribute to the safe use of preservatives, advancement of wood modification techniques, as well as recycle and disposal of treated material. Therefore, in this study, the most current research and advancements promoted in the wood protection in academia are discussed which including an overall summary of the recent developments on wood preservatives, different types of preservatives, natural preservative compounds, and modification technologies in academia.

“…Specimens treated with waterborne copper naphthenate (1% Cu) were also largely sound, with a few specimens showing early stages of decay. Copper naphthenate has been used in combination with other preservatives such as borate salts in ties and bridge ties (Lloyd et al 2017) and for remedial or supplemental treatment of poles, piles, bridge components and other commodities after years in service to extend their useful service life (Barnes et al 2011).…”

This paper reviews the history and use of copper naphthenate as a heavy-duty wood preservative, with a focus on use patterns within the USA and opportunities for expansion in Canada and Europe. Copper naphthenate has demonstrated efficacy to preserve and protect cellulosic and wooden items essential to critical infrastructure and is an ideal choice for use in the replacement of pentachlorophenol and creosote where less toxic and environmentally friendlier alternatives are required.

Before being put to use, wooden railway sleepers are impregnated with creosote to increase their longevity and protect them from any adverse environmental impact. Creosote consists of a number of chemical substances, and some of those substances, namely, the polycyclic aromatic hydrocarbons, phenolic compounds and heterocyclic aromatic compounds, are potent carcinogens. Apart from polycyclic aromatic hydrocarbons and phenolic compounds, during their use, sleepers are mostly contaminated with heavy metals and petroleum products. Upon railway reconstruction, wooden railway sleepers become the waste, which must be handled by the current legislation of the European Union. After determining the concentration of contaminants with laboratory research, it is possible to identify their hazard level and classify them as hazardous or non-hazardous waste. After conducting laboratory research on the waste of wooden railway sleeper analysed, they are classified as hazardous waste.
