... In this study, we conducted a survey to quantify and assess the generation of wood waste by Ohio’s wood industry cluster. We find that large amounts of wood waste are produced in the state, and that limited markets exist for their use. These findings suggest a potential need for cooperative structures to manage and find markets for sawmills, as well as the need for a recycling facility to handle t ...

Abstract:
... Wood dust produced in medium-density fiberboard (MDF) processing is a major occupational hazard in wood industry and may damage processing equipment. In many wood processing factories, dust collecting systems need to be optimized for the distributional and morphological characteristics of dust in the workshop so that economical and efficient dust control can be achieved. In this study, weighting, ...

Abstract:
... The practice of timber harvesting in natural forests which has been conducted up to now still leaves wood harvesting residue and residual stand damage. Most condition of wood harvesting residue is still good and can be utilized. The objective of this research was to determine the potency of wood harvesting residue and residual stand damage on timber harvesting in natural forests. The data on wood ...
... This study aims to determine the sorption isotherms of three tropical woods from Cameroon to understand the conditions for their use and drying. The equilibrium moisture contents were experimentally determined using saturated salt solutions. Some anatomical parameters were also measured to assess the influence of the structure of these woods on their sorption behaviour. Among the sorption models t ...

Abstract:
... Assessing intrinsic wood qualities such as modulus of elasticity and internal decay in trees and logs can be challenging. However, acoustic technologies have been investigated for a possible solution. This paper reviews available literature on non-destructive acoustic methods for assessing wood quality, both in tree and log form. The paper further reviews the effects of silvicultural practices (su ...

Abstract:
... For wood screw connections, the withdrawal capacity is essential and is therefore an optimization target for wood screws. The withdrawal capacity is based on the composite action between the screw thread and the wood. Optimizing thread geometry requires knowledge of how thread parameters influence the withdrawal capacity. Up to now, this knowledge is largely unknown. Therefore, the objective is to ...

Abstract:
... Nowadays, sustainability is one of the critical factors for the success of supply chains in organizations and firms that strive to maintain a competitive edge in the market. In wood industry, due to the need for integrating several business units such as forest entrepreneurs, carriers, pulp and paper mills and sawmills, such industries encounter various difficulties in maintaining effective supply ...

Abstract:
... We incubated 196 large-diameter aspen (Populus tremuloides), birch (Betula papyrifera), and pine (Pinus taeda) logs on the FACE Wood Decomposition Experiment encompassing eight climatically-distinct forest sites in the United States. We sampled dead wood from these large-diameter logs after 2 to 6 y of decomposition and determined wood rot type as a continuous variable using the lignin loss/densit ...

Abstract:
... Aminoplastic particleboard adhesives are reactive, inexpensive and well established in industry. Even so, potential adhesive savings are of interest due to a number of reasons. Therefore, fibrillar cellulosic additives derived from sugar beet pulp and from wood pulp were examined with regard to beneficial effects on adhesive performance. Particleboards were prepared with, varying adhesive content ...

Abstract:
... Wood science covers in particular the areas of the formation and composition as well as the chemical, biological and physical-mechanical properties of wood. First comprehensive studies have already been published in the last century. Detailed knowledge of wood is required for the processing of wood, the production of wood-based materials, and the utilization of wood and wood-based materials as bui ...

Abstract:
... The uptake of moisture severely affects the properties of wood in service applications. Even local moisture content variations may be critical, but such variations are typically not detected by traditional methods to quantify the moisture content of the wood. In this study, we used near-infrared hyperspectral imaging to predict the moisture distribution on wood surfaces at the macroscale. A broad ...

Abstract:
... Poplar is raw material for various panel, paper and fiber products. The 12 sample trees of clone Nanlin-895 from four spacings were destructively harvested after thirteen growing seasons to assess the influence of spacing on radial growth and wood properties. Spacing significantly affected tree-ring width and wood basic density (p < 0.05) but not fiber traits. The highest diameter and wood basic d ...
... Based on the measurements of the biomass of the stems of 3 699 trees of Scots pine, Norway spruce, and silver birch in Europe since 1950, it has been shown that these tree species show a reduction in biomass and wood density. These results contradict the fact that the volume of wood is directly converted to biomass using the historical values of the conversion rates. From 1950 to 2020 the biomass ...

Abstract:
... Wood density (WD) is a central trait driving life-history variations among tree species. Density, however, is a property of wood that depends, in angiosperms, on three cell types, namely vessels, fibers and parenchyma. These wood cells are mainly involved in water transport, mechanical support and storage, respectively. Therefore, wood anatomical traits may provide a more mechanistic understanding ...

Abstract:
... Poplar is an important tree species in the phytoremediation of Cadmium (Cd) in the soil. However, the research on its transport and accumulation mechanism in wood cells has not been conducted. In this paper, Poplar 69 [Populus deltoides Bartr. cv. ‘Lux’ (I-69/55)] was selected to study the distribution of Cd accumulated in the wood, both macroscopically, by Cd analysis along the trunk heights, and ...

Abstract:
... KEY MESSAGE: The higher the basic density and the lignin content, the higher the cleavage strength tends to be and the less prone to checking the wood tend to be. The checks that often affect Eucalyptus wood, also called cracks or cleavages, depreciate the material and cause considerable loss of yield in higher value-added products for the sawn wood industry. Information about the influence of bas ...

... In this study, the fuzzy analytic hierarchy process was employed to prioritize some factors affecting the surface roughness of wood and wood-based materials in CNC machining. Within the model, four main factors and eighteen subfactors were defined. After constructing the hierarchical structure, the factors were analyzed through experts’ opinions. The results demonstrated that wood properties and m ...

Abstract:
... Wood, which belongs to organic-based building materials, is useful and natural. Despite the many benefits, environmentally exposed wooden building elements are prone to weathering and gradual damage that significantly reduces the structural durability of aged wooden buildings. To effectively assess the structural health of wooden buildings, it is vital to detect, categorize and localize the damage ...
