Declaring life cycle inventory of toxicity related emissions in environmental product declarations of preservative treated wood products
2018 - IRG/WP 18-50339
Life cycle assessment (LCA) including impacts on toxicity for preservative treated wood has been shown to have large uncertainties. With the growing demand for verified LCA in environmental product declarations (EPD), the need for reliable data is crucial for realistic assessment of wood products. Uncertainty is caused by several issues such as service life prediction, leaching rates and calculati...

Environmental protection and long term in-service sustainability of preserved wooden poles is secured by non-toxic barrier protection system – History and case studies in South Africa
2018 - IRG/WP 18-50340
Non-toxic flexible sheeting systems have been developed to encapsulate the ground contact regions of preserved wooden poles and prevent their premature failure in South Africa since 1992 but the technology also has a long history of resistance by individuals with vested interests in the built-in redundancies of such poles. The concept has, however, been simultaneously validated by many independent...

CCA wood preservative: Trust with destiny
2019 - IRG/WP 19-30731
This paper traces the history of Copper-Chrome-Arsenic (CCA) and its current status in India and worldwide. CCA was invented as ASCU at the Forest Research Institute, Dehra Dun in 1933 by Dr. Sonti Kamesam. Although its efficacy was doubted by the British colonial rulers resulting in several hiccups at home, the patent rights were purchased by US Bell Telephone Co. and it was adopted by the US woo...

Thermal performance and fire safety properties of traditional circumferential log-cabin walls
2019 - IRG/WP 19-40872
The paper describes the experiment of fire resistance of a circumferential log-cabin wall fragment using various structural modification of the gap between two log members. The influence of the gap structural modification on the criterion of fire resistance E (envelop integrity) and I (insulation) is evaluated. The evaluating criteria are represented by the development of temperatures measured in ...

Durability and climate change - implications for wood building structures
2019 - IRG/WP 19-50361
Sustainable building practices are rooted in the need for reliable information on the long-term performance of building materials; specifically, the expected service-life of building materials, components, and assemblies. This need is ever more evident given the anticipated effects of climate change on the built environment and the many governmental initiatives world-wide focused on ensuring that ...

Aiming for eco-friendly log production and wooden construction!
2021 - IRG/WP 21-50365
In order to reduce greenhouse gas (GHG) emissions to zero by 2050 in the fields of forest and forest products, it is necessary to promote appropriate management and renewal of planted forests, and development of wooden building materials and the wooden construction of mid-to-high-rise buildings with lower GHG emissions. Unless we also try to reduce the environmental loads other than GHG for such d...

DuraSoft Project: a multidisciplinary approach for softwood protection
2021 - IRG/WP 21-50367
Over the course of millennia, fishing and agro-pastoral activities have produced unique housing types in the Italian lagoons and in the Slovenian highlands where the use of wood is predominant. They are associated with wooden service infrastructures such as piers, moorings, piling and fences. However, the existence of these structures and the associated cultural heritage are subject to constant ...

Evaluation of ecotoxicological effects of different coniferous wood treatments on two marine bioindicator species
2022 - IRG/WP 22-10999
Coniferous wood panels (Picea abies) were treated with two concentrations of copper-based impregnating agent to increase its durability in marine and brackish environment. In order to assess the environmental compatibility of the treatments a laboratory experiment was conducted with two marine invertebrate species: bivalve Mytilus galloprovincialis and a gastropod Steromphala albida. The bioindica...

Simulations of microclimates for wood-decaying fungi in the built environment using environmental analysis
2023 - IRG/WP 23-20703
Simulations of fungal decay risk were run on two similar building geometries exposed to typical annual climate conditions of two different geographical locations, Brunswick (Germany) and Cairns (Australia). The simulations were conducted to capture the effect of wind-driven rain and solar irradiation exposure over nodes of the common building geometry. The moisture content and temperature variatio...

CIOL Wood - towards industrial scale production
2023 - IRG/WP 23-40980
CIOL® is a new, low cost, non-toxic wood modification system, needed to replace traditional and non-sustainable alternatives with great potential. It’s important to find sustainable, environmentally friendly replacements to heavy metals and biocides. In the new European Bauhaus, Ursula Von der Leyen, president of the European commission, talks about how new living environment should be beautifu...

Multi-scale Experimental Study on Self-sustained Smouldering of CCA-treated Timber Poles
2023 - IRG/WP 23-40988
While it is accepted that appropriate treatment with chromated copper arsenate (CCA) will extend the design life of wood markedly, there are concerns regarding the effect of treatment on fire performance. Smouldering combustion in CCA-treated timber infrastructure can self-sustain, destroying the timber elements, as the chromium and copper present in the CCA can act as catalysts of the smouldering...

Environmental Benefits of Wood Preservation
2023 - IRG/WP 23-50377
Over the past decade or two, many people have become significantly more aware and concerned about the global environment and the health of our planet. Building with wood products from sustainably managed forests carries significant environmental benefits. The ability of a growing tree to absorb carbon dioxide (CO2) and sequester the carbon is beneficial in the role of combating rising CO2 levels...

Enhanced durability of bio-based materials for green building
2023 - IRG/WP 23-50382
Wood protection technologies provide tools to enhance the durability of bio-based materials for green building. Both wood and related bio-based material are regarded as eminent for green building. It allows to underpin several of the United Nations sustainable development goals and is regarded critical for the Green Deal objectives of the EU. Nevertheless, to enhance the potential it needs to be b...

Quantifying metal migration from a deck constructed with copper-azole-treated lumber
2024 - IRG/WP 24-50391
Soluble copper or micronized copper wood preservatives are the most common available wood preservative systems for residential applications in the United States. Copper containing wood preservatives have been scrutinized for their potential negative impacts on the environment, across many jurisdictions. Concerns arise from the potential for preservatives to migrate out of treated wood upon water e...
