The use of light organic solvents in industrial wood preservation - an environmental perspective
1995 - IRG/WP 95-50040-22
The paper examines the evolving regulatory environment concerning the use of hydrocarbon solvents in industry and, in particular, the European wood preserving sector. The implications of the proposed EU Directive on industrial solvent use are explained and possible responses to such regulation examined, including process modification, product changes and emission abatement, where necessary. The de...

Potential use of an emulsified tar oil fraction as a wood preservative: Preliminary technological and environmental assessment
1994 - IRG/WP 94-50028
In order to meet the recent environmental concern specifications of creosote are altered, the B[a]P content is limited and restrictions on the emission of volatile organic compounds (VOC) and higher polyaromatic hydrocarbons (PAH) are expected in some countries. Research has been conducted on an emulsion of a selected tar oil fraction. Using a waterborne formulation opens new perspectives for targ...

Identification and inhibitory effect of volatiles from different ages of a Trichoderma aureoviride culture on selected wood decay fungi.
1995 - IRG/WP 95-10110
The ability of a Trichoderma sp. to produce volatile organic compounds (VOCs) over a four week period of growth was examined and the inhibitory effect of these volatiles against four selected basidiomycetes over the same period was assessed. After trapping, on tubes filled with chromatography packing material, VOCs were analysed on an integrated automated thermal desorbtion mass spectrometer syste...

New method to find out the volatile organic compounds (VOC) of wooden material
2000 - IRG/WP 00-20189
Volatile organic compounds (VOC) of pine, spruce and larch wood were studied using a new technique developed at VTT Chemical Technology. 50 mg of crushed wood material was placed into glass tubes. The tubes were closed with a glass wool, which is pressed with a tube cap. Wood samples were analysed with a gas chromatograph after thermal desorption using four different temperatures (50°C, 100°C, 1...

The use of thermal desorption and pyrolysis combined with a semiconductor VOC detector for the on-site detection of preservative-treated wood
2010 - IRG/WP 10-20456
The purpose of this study was twofold; to identify possible marker molecules released from preservative-treated wood upon heat treatment and then develop a prototype detector for this marker. Two methods for heating the samples were used: Pyrolysis combined with Gas-Chromatography with IR-detection and Thermal Desorption combined with Gas-Chromatography with mass detection. A first prototype detec...

VOC-free remedial treatment agent on organic solvent basis with surface cleaning by photocatalysis using titanium dioxide
2014 - IRG/WP 14-40651
Due to the EU Regulations according to the harmonisation of the European market of biocidal products and the EU Regulations regarding emissions of volatile organic compounds in residential properties a new VOC free yet organic solvent based remedial treatment agent is introduced including a potential method to clean up the wooden surface of remaining biocides after a remedial treatment using photo...

A non-VOC approach of solvent-based wood preservatives for remedial treatment
2016 - IRG/WP 16-30681
Solvent-based wood preservatives are the workhorses in the field of remedial treatment. Due to new European regulations on the indoor air quality there is an increasing pressure on the VOC-content on these solvent-based product types. The transfer of these European regulations into national law is left up to each European member state and handled in different ways. E.g. France has introduced a VO...

Tree bark as a renewable source of wood protection materials for building applications (BarkBuild)
2023 - IRG/WP 23-30792
The BarkBuild project aims to address climate change mitigation by developing new, sustainable, and long-lasting wood building materials with low environmental impact. The project focuses on developing bark-based wood protection and building formulations that demonstrate technical performance, safety, and sustainability in both outdoor and indoor applications. The research objectives of the projec...
