Co-incineration of CCA-treated wood and Municipal Solid Waste in MSWI plant
2005 - IRG/WP 05-50224-19
The Norwegian Association of Energy Users and Suppliers (Norsk Energi) have carried out incineration tests with addition of 10 % by weight CCA-treated wood waste to municipal solid waste in a MSWI plant. The objective with the test was to determine emissions and composition of bottom ash. The incineration test was done at the Klemetsrud plant in Oslo The main conclusions are: -No significant inc...

Bioassays of extracts from scaly ash (Ganophyllum falcatum B1) against the subterranean termite Coptotermes acinaciformis (Froggatt)
1983 - IRG/WP 1206
Scaly ash, Ganophyllum falcatum B1. wood shavings were extracted by methanol, and fractionated with ethyl acetate, diethyl ether and water, and the anti-termitic properties of these materials bioassayed against the subterranean termite Coptotermes acinaciformis (Froggatt). Laboratory techniques were developed to overcome the problem of limited extractive materials. The results of the various bioas...

Durability of heat-treated wood
1999 - IRG/WP 99-40145
Heat-treated wood from the French process were laboratory tested against decay using agar block test and a modified soil block test. Water absorption, bending strength, lignin content and acid number were also determined to evaluate the effect of heat treatment. Heat treated samples exhibit a higher lignin content and a lower acid number compared to untreated control indicating the degradation of ...

Long-Term Release of Arsenic, Chromium, and Copper from CCA-Treated Wood and Ash
2005 - IRG/WP 05-50227
In this study, laboratory long-term leaching studies were conducted to characterize the leaching behavior of arsenic, chromium, and copper from CCA-treated wood samples (block, chip, and sawdust) and CCA-wood ash and to determine the rate of release of the metals from the CCA wood products. The leaching solutions were periodically collected and analyzed for the concentrations of arsenic, chromium,...

The effect of woody and non woody plants extractives on microbial resistance of non-durable species
2006 - IRG/WP 06-30392
The effect of Elm (Zelkova carpinifolia), Oak (Quercus castanifolia), Mulberry (Morus alba), Ash (Fraxinus excelsior) as woody plants, Rose (Rosa damascene) and Fumitory (Fumaria sp) as non woody plants extractives on durability of Beech (Fagus orientalis), Maple (Acer insgin), Alder (Alnus subcordata), and Lime (Tilia sp) were studied. First wood species having extractives were cut to small piece...

Treatment of Green Logs infested by Exotic Pest: Case Study of the Emerald Ash Borer: Agrilus planipennis Fairmaire
2007 - IRG/WP 07-10628
Invasive alien insect species periodically infest forests in the United States causing the destruction of plant species and decimating populations, resulting in significant economic and ecological losses for areas involved. The Emerald Ash Borer (EAB) was first discovered on North American soil in the summer of 2002 near Detroit, Michigan and has since spread to several other Midwestern states and...

Morphological and Impregnability Properties of Narrow-Leaved Ash (Fraxinus angustifolia Vahl.) Wood Taken From Plantations with Different Spacings
2009 - IRG/WP 09-40475
Narrow-Leaved Ash, an important hardwood in Turkey, (Fraxinus angustifolia) is one of the fast growing species. In Turkey, several plantations have been established for 40 years. Narrow-Leaved Ash grows very fast and produces 25 (m3/year) mean increment. Except for eucalyptus and poplar, this increment is the highest compared to the other imported fast growing wood species. Until 1980, the spacing...

Resistance of heat treated Ash wood under steam pressure: rot fungi, soil micro-organisms and termites
2016 - IRG/WP 16-40724
Thermal modification processes have been developed to increase the biological durability and dimensional stability of wood. The aim of this paper was to study the influence of ThermoWood® treatment intensity on wood decay resistance improvement against soil-inhabiting micro-organisms, brown/white rots and termite’s exposures. All of the tests were carried out in the laboratory with two differen...

Chemical, physical-mechanical characterization and durability of thermally modified beech and ash wood by thermo-vacuum process (Termovuoto)
2016 - IRG/WP 16-40758
The paper illustrates part of the results from the CIP Eco-innovation project “Thermo-vacuum: new process for new generation of thermally modified wood”. The project is part of the 7th Framework Programme for European Research and Technological Development, and thermo-vacuum modified wood is already on the European market. The project was selected by the European Commission, EASME Agency, as "...
