The evolution of laws on the use of biocide products has led to important changes in the field of wood preservation leading to an increasing interest for non “biocidal treatments” like thermal or chemical modifications. While thermal modifications become more and more common on industrial scale, development of chemical modifications progresses slowly. One reason for the challenges encountered i...
The influence of physical and chemical properties of 20 species of imported wood on degradation of the wood by termites under field conditions was studied. The wood species studied were: Sycamore maple, Acer pseudoplatanus L. (Sapindales: Sapindaceae) (from two countries), Camphor, Dryobalanops aromatic C.F.Gaertner (Malvales: Dipterocarpaceae), Beech, Fagus grandifolia Ehrhart (Fagales: Fagace...
Abstract Four variants of the thermochemical modification were conducted on beech wood at a temperature 130 °C, employing NH 4 OH concentrations 5% or 10% for durations either 12 24 h. The weight% gain (WPG) and bulking coefficient (BC) initially calculated. Subsequently, wood’s degree discoloration was assessed using CIELAB-colour-system. Chemical structure alterations determined through Fouri...
An essential element for the sustainable use of renewable resources is an efficient comminution process. For processes, detailed knowledge fracturing processes necessary. Therefore, single-particle under impact stress was investigated, and influence moisture content particle size in beech wood described. The extent applicability existing models to wood, modeling breakage probability function br...
Wood fly ash is an industrial by-product of the combustion of different wood materials and is mostly disposed of as waste on landfills. In our preliminary experiments, wood ash exhibited antibacterial activity against urban wastewater bacteria and we focused on wood fly ash as a potential substrate for wastewater disinfection. The addition of ash at a concentration of 10 g L⁻¹ (1%) caused an in...
