CreoSub – New protection technology to substitute creosote in railway sleepers, timber bridges, and utility poles
2014 - IRG/WP 14-30644
Creosote oil is one of the oldest industrially used wood preservatives. Due to its toxic profile, the European Commission has restricted the use of creosote specific applications, but it is highly controversial within the European Commission. Its approval for use after 2018 is very questionable and may depend on derived research results until then, i.e., the viability of alternatives developed to ...

A Green and Novel Technology for Recovering Copper and Wood from Treated Waste - Part I
2015 - IRG/WP 15-50309
Preservative treatment of wood extends its service life. The US consumes about 70 million pounds of copper and produces about 7 billion board feet of treated wood annually. Burning and reusing CCA and copper treated wood wastes are disallowed by US EPA due to health and environmental concerns. Millions of pounds of copper and wood are disposed by landfill annually. The objective of this study was...

A Green and Novel Technology for Recovering Copper and Wood from Treated Wood Waste – Part II: Optimization, copper metal recovery, and process design
2017 - IRG/WP 17-50326
The US consumes 70 million pounds of copper and produces 580 million cubic feet treated wood annually. The EPA disallows burning and reusing treated wood waste due to health/environmental concerns. Vast quantities of copper and wood are landfilled. Two safe and low cost extraction systems, citric acid and ammonium citrate, were identified in Part I of this study. In Part II of the study, effects o...

The InnovaWood Module Bank: Building an international e-learning platform for shared MSc courses in wood science and technology
2019 - IRG/WP 19-50355
The InnovaWood Module Bank is a shared e-Learning platform for standalone science, technology and education modules in wood science. A group of members of InnovaWood have committed to jointly develop this platform. The institutes benefit in that they can widen the range of courses they offer and use their teaching capacities more efficiently. Students obtain the possibility to take online courses ...

Bioremediation technology for cleaning-up of the soil contaminated with creosote oil – the overall concept of BIOREM project
2020 - IRG/WP 20-50363
The aim of the communication paper is to present the conceptual framework of the BIOREM project, which started in May 2019. The final result of the entire project will be an innovative bioremediation technology that can be used in areas contaminated with creosote oil – a commonly used wood preservative being a complex mixture of various compounds such as polycyclic aromatic hydrocarbons (PAHs). ...

A new approach to wood protection: Potential of biologically synthesised CuO and ZnO nanoparticle formulation as a wood preservative
2022 - IRG/WP 22-30758
Even though metal nanoparticles are effective in protecting wood, they are less preferred, as they are synthesised using methods which are expensive and are not environmentally friendly. Biological synthesis of nanoparticles using plants, fungi, yeast, bacteria and viruses, has been accepted as an alternative approach and is referred to as green synthesis. Utilization of biologically synthesised n...

A novel wood preservation technology improving durability and water-related properties
2022 - IRG/WP 22-40926
A newly developed silicone oil (Archroma Management GmbH, Switzerland) was tested for wood modification purposes. Scots pine sapwood was treated with aqueous solutions of this silicone oil and showed a penetration of the modification agent into the wood cell wall. Both, biological durability and moisture-related properties, experienced significant improvements by the modification. Besides, the mod...

Recent studies into improved fire retardancy of wood undertaken at Luleå University of Technology
2023 - IRG/WP 23-30784
Modern construction is moving more towards engineered wood products, such as glulam and cross-laminated timber (CLT). This increase is driven by the aspiration to deliver high-rise buildings with enhanced environmental profiles and human well-being. This desire to use wood in construction is pushing the need for fire treatments capable of meeting a products service life. However, the use of wood ...
