“…Work with plantation-grown hybrid poplars has shown the potential to produce lumber suitable for appearance grade applications when prairie-grown (Knudson and Brunette 2015). Other species-specific work includes research by Clement et al (2004) that analyzed the component part distributions possible from sawing lumber from short-length white birch (Betula papyrifera Marsh.)…”

“…However, it has been noted that in recent years hardwoods in general (Schuler et al 2001) as well as specific hardwood species such as poplar and hybrids (Balatinecz et al 2001, Knudson andBrunette 2015) have realized increased utilization opportunities in the manufacture of various engineered wood products. Furthermore, low-grade hardwoods have long been used in the manufacture of pulp and paper.…”

There is a substantial body of research from the past half-century addressing hardwood utilization and markets in North America. This synthesis is the first to our knowledge to consider two major (and related) aspects of this research concurrently: low-grade hardwood utilization and marketing of character-marked wood features. We first consider low-grade hardwood resources, products, and key challenges in processing and utilization researched since the 1970s. We then discuss several themes influencing marketing of character-mark products, including product development and consumer and retailer response. This review (considering 119 scientific papers) should help guide future research and value-added utilization of low-grade hardwoods, as it identifies important research results, needs, and gaps yet to be filled. These findings are important in an era of structural changes in the North American hardwood industry and increased pressure to maximize economic value from all hardwood resources.Keywords: low-grade hardwoods, character-marks, value-added hardwoods, industrial wood use, product design, smalldiameter timber, wood perception RÉSUMÉ Une quantité considérable de travaux de recherche a été effectuée au cours des cinquante dernières années sur l'utilisation et les marchés pour les bois de feuillus en Amérique du Nord. Cette synthèse représente à notre connaissance la première étude simultanée des deux aspects les plus importants (et associés) : l'utilisation des bois de feuillus de faible valeur et la mise en marché des caractéristiques des bois avec défauts. Nous avons en premier lieu étudié les ressources en bois de feuillus de faible qualité, les produits et les principaux défis rattachés à sa transformation et son utilisation depuis les années 1970. Nous avons par la suite analysé plusieurs aspects qui influencent la mise en marché de produits de bois avec défauts, incluant le développement de produit ainsi que la réaction des consommateurs et des distributeurs. Cette synthèse (portant sur 119 articles scientifiques) devrait permettre de guider les recherches à venir et la mise en valeur des bois de feuillus de faible valeur marchande, puisqu' elle identifie les résultats de recherche les plus importants, les principaux besoins et les lacunes à combler. Ces résultats ont une importance capitale en cette ère de changements structuraux dans l'industrie du bois de feuillus en Amérique du Nord et alors qu'augmentent les pressions pour maximiser la valeur écono-mique de toutes les sources de bois de feuillus.Mots clés : bois de feuillus de faible valeur, bois avec défauts, bois de feuillus à valeur ajoutée, utilisation industrielle du bois, conception du produit, bille de faible diamètre, perception du bois

“…Investigations by Shukla and Kamden (2008) prove that low-density wood such as silver maple, yellow poplar and aspen can also be effectively applied in the production of LVL. According to Knudson and Brunette (2015) yellow poplar (Liriodendron tulipifera L.) as well as red alder (Alnus rubra Bong.) which are used in the production of interior design elements can be substituted by hybrid Walker poplar (P. deltoides P. petrowskyana) which is characterized by low density, similar to that of aspen, i.e.…”

The paper investigates the possibility of producing the water-resistant plywood of increased elasticity with use of veneers attained from European wood species, such as alder, birch, beech, pine as well as linden, poplar, willow and spruce. Plywood was produced in two variants. Variant I of plywood was made from various wood species, yet the veneers were of the same thickness. In variant II the centre layer in each case was made from 1 mm thick pine veneer and the face layers were made from 1.4 mm thick veneers of various wood species. The produced plywood was subjected to tests on modulus of rupture, modulus of elasticity and tensile strength, bond quality and compression ratio. Specific values of modulus of rupture and modulus of elasticity were also determined taking into consideration the differences in the thickness of applied veneers. Based on these investigations, the authors concluded that, regardless of the manufacturing method, the highest values of modulus of rupture as well as modulus of elasticity and bond quality are achieved for plywood made from linden, poplar, willow and spruce. The change in the plywood structure (variant II) resulted in a considerable decrease in the values of modulus of rupture and modulus of elasticity (and their specific values) both parallel and across the grain. The lowest values of these parameters were obtained for poplar, linden and willow plywood. What is more, as a result of the applied procedure the bond quality of the produced plywood increased and the compression ratio was reduced. Taking the above into account, we can assume that linden, poplar and willow wood is an optimum choice for the face veneers of plywood with increased elasticity. The centre layer of this kind of plywood can be made from pine veneer of lesser thickness.

“…Beyond traditional products, such furniture parts, picture frames, interior mouldings, venetian blinds, chopsticks, kitchenware, toys and pallets, over the last years hybrid poplar has been successfully used in the building sector, where lightweight wooden constructions increase the market share thanks to prefabrication and their great acoustic and thermal insulation performance . In particular, hybrid poplar has been used for outdoor applications such as veneers (Knudson and Brunette 2015) and WPC (Wood Plastic Composite) exterior decking (Fabiyi and McDonald 2010). In these cases, a comprehensive knowledge concerning the effect of weathering on material properties and the chemical modifications that can be applied in order to reduce wood degradation drawbacks assumes significant importance.…”

The effect of acetylation on weathering resistance of a hybrid poplar (Pacific Albus®) was studied by colour change evaluation, mechanical tests, FT-IR spectroscopy and moisture absorption measurements. The acetylation process was performed without any pre-treatment and it was verified by means of weight percentage gain and FT-IR spectroscopy: the average weight percentage gain was 14.4 ± 0.6% and the band areas at 1370 and 1740 cm −1 increased about 50% compared to unmodified wood. It was also demonstrated that acetylation process increased mechanical performance and reduced wood moisture absorption. Unmodified and acetylated wood samples were artificially weathered with a Xenon-arc lamp up to 400 h. The mechanical properties of both acetylated and untreated wood showed the same trend, but acetylated samples exhibited higher stiffness, strength and elongation at break. The outcomes demonstrated that acetylated samples were more stable to degradation mechanisms induced by artificial weathering.
