Abstract
1re partie Empreinte environnementale du CLT – résultats préliminaires Dans la présente partie, nous déterminons expérimentalement certaines caractéristiques environnementales quantifiées du CLT en tant que matériau de construction, sans toutefois effectuer une analyse du cycle de vie (ACV) exhaustive. Puisqu’il n’existe aucune documentation comparative sur le CLT, nous utiliserons plusieurs approches pour estimer son empreinte environnementale et pour le comparer au béton. À l’aide des données d’ACV existantes du bois lamellé-collé canadien en tant que valeurs de remplacement, nous examinerons l’empreinte du matériau en soi comparé aux matériaux du béton armé ainsi que des matériaux utilisés dans les bâtiments de moyenne hauteur comparativement au béton. Nous ajusterons ensuite les données de l’ACV du bois lamellé-collé pour qu’elles se rapprochent de celles d’une section de plancher de CLT aux fins de comparaison à une section de plancher en béton équivalente sur le plan fonctionnel. Dans chacun des cas, nous estimons que le CLT surpassera considérablement le béton dans chaque mesure environnementale abordée selon l’ACV. 2e partie Effets potentiels sur la qualité de l’air intérieur de l’utilisation du CLT dans les bâtiments – résultats préliminaires Cinq produits de bois lamellé-croisé de différentes épaisseurs et lignes de collage ont été testés aux fins d’analyse de leurs composés organiques volatils (COV) comprenant les émissions de formaldéhyde et d’acétaldéhyde afin d’aider les ingénieurs et les constructeurs à mieux choisir les matériaux de construction ayant le moins d’incidence sur la qualité de l’air intérieur. Les émissions ont été évaluées selon la norme ASTM D 5116 et ont été recueillies après que les échantillons aient été exposés dans la chambre d’essais pendant 24 heures. Aucune corrélation n’a pu être établie entre l’épaisseur du bois lamellé-croisé, les lignes de collage ou la quantité de COV individuels (COVi) émis, comprenant le formaldéhyde et l’acétaldéhyde, ou les COV totaux (COVt). Les cinq produits de CLT ont démontré de très faibles taux d’émissions de COVi et de COVt. La plupart des COV détectés provenaient de composés de terpène de bois résineux utilisés dans la fabrication de bois de construction laminé. Ainsi, lorsque le CLT est employé dans la construction d’un bâtiment, l’effet des COV sur la qualité de l’air intérieur est mineur, voire inexistant. Lorsqu’on évalue les effets du produit sur la qualité de l’air intérieur, on peut facilement conclure qu’il serait négligeable, sinon nul. Les résultats relatifs aux COVt et aux émissions de formaldéhyde des cinq produits de bois lamellé-croisé après une exposition de 24 heures étaient généralement inférieurs à ceux indiqués dans les systèmes européens de marquage des émissions. En outre, le niveau européen E1 pour les émissions de formaldéhyde des produits de bois, qui est établi à 0,1 partie par million (ppm) ou à 100 parties par milliard (ppb), est de 6 à 20 fois supérieur aux niveaux mesurés pour les produits de bois lamellé-croisé. D’ici juillet 2012, l’application de la phase 2 des normes du CARB (organisme de réglementation de l’État de Californie) relative à tous les produits composites sera complétée et les limitations d’émissions de formaldéhyde seront établies à des valeurs variant entre 0,13 ppm (130 ppb) pour les panneaux de MDF (panneaux de fibres de densité moyenne) minces et 0,05 ppm (50 ppb) pour le contreplaqué de feuillus avec noyau de composite (HWPW-CC). En comparant ces limitations à celles des produits de bois lamellé-croisé, on peut conclure que ces produits respectent amplement les limitations les plus rigoureuses du CARB, qui sont de 50 ppb.

Abstract
FPInnovations commissioned the Athena Institute to develop a biogenic carbon calculation tool for use in Environmental Product Declarations, EPD’s, developed under their Product Category Rules, PCR, for North American wood products. Athena has developed two such tools to supplement two types of LCA studies. Cradle-to-gate: Cradle-to-gate LCA refers to those that begin in the forest “cradle” and end with the packaged product at the manufacturing “gate”. Business-to-business, B2B, EPD’s are developed form cradle-to-gate LCAs. Cradle-to-grave: Cradle-to-grave LCA includes the cradle-to-gate processes as well as the transportation to user, end-use, and end-of-life treatment or “grave”. Business to Consumer, B2C, EPD’s are developed from cradle-to-grave LCAs.

Abstract
This study provides a comparative life cycle assessment (LCA) of a 4060 m2, 4-storey cross laminated timber (CLT) apartment building located in Quebec City, Canada and an equivalently designed building consisting of reinforced concrete slabs and columns with light gauge steel studded walls (CSSW). The emergence of CLT as a structural material that can be used in mid-rise building structures combined with limited work investigating the environmental performance of CLT in building applications provides the motivation for this comparative study.

Abstract
This study presents a cradle-to-gate life cycle assessment (LCA) of hardwood lumber produced in eastern Canada. LCA is a comprehensive analytical examination of the flows to and from nature related to a product or a process. LCA is typically performed following international protocols and is considered by many to be the best mechanism for quantifying the true environmental footprint of a product. An LCA can address some or all of the stages in the life of a product. This LCA addresses environmental impacts up to the mill “gate” for hardwood lumber; such a cradle-to-gate assessment is typical for products that are usually destined to be components in any number of secondary products. For those secondary products, a full cradle-to-grave LCA could be developed (incorporating effects from transportation, installation, usage and disposal), using the cradle-to-gate LCA as part of the input data. 201002820 - 1.1

Abstract
Chitosan is an amino polysaccharide obtained from the deacetylation of chitin, which is naturally occurring in the shells of a large number of marine crustaceans. Chitosan is soluble in weakly acidic aqueous solutions and possesses adhesive properties. Chitosan has received much attention for medical and industrial applications; however, only limited studies have been conducted on the application of chitosan as a wood adhesive, because its bonding properties on wood are poor. To improve the adhesive quality of chitosan resin, an innovative study on chitosan adhesives has been conducted to use selected fungal species to modify chitosan and improve its bonding properties, to synthesize non-formaldehyde resins with the fungus-modified chitosan, and to enhance urea-formaldehyde (UF) and phenol-formaldehyde (PF) resin performance with the fungus-modified chitosan. The bonding properties of wood composites made with these chitosan-based green wood adhesives were significantly improved, in terms of lap-shear strength. Unmodified chitosan solution was not compatible with ammonium lignosulfonate, liquid PF resin, soybean resin, powder PF resin, or soybean flour, but was compatible with UF resin, polyvinyl acetate (PVA) resin, and phenol. With the addition of chitosan in UF and PVA resins, both the dry and wet shear strengths of plywood panels were improved, compared with those of panels bonded with the control UF and PVA resins, i.e. without chitosan. A number of chitosan and chitosan-reinforced UF resins were prepared as a binder for particleboard panel manufacturing. Six (6) types of particleboard panels with different levels of resin loadings and press conditions were manufactured. The resulting boards were tested to evaluate the bond quality of the chitosan and chitosan-reinforced UF resins. The test results showed that particleboard panels with good visual quality could be produced with all formulations of chitosan-UF adhesives, even with resin systems made with 1% of chitosan resin only. All chitosan resins used alone or added to UF resins yielded panels with better internal bond (IB) strength than those made with the UF control resin. The panels made with 1% chitosan resin plus 66% UF resin in a 1:1 ratio yielded panels with the highest IB strength and the best overall mechanical properties.
