“…Some research has been performed regarding its ability to bond wood. [1][2][3][4] Wheat gluten is an industrial by-product from wheat starch processing, and the annual worldwide production is $ 400,000 metric tons. 5 It possesses unique viscoelastic properties and is mainly used in the bakery industry, although the field of food applications varies worldwide.…”

Plant proteins, such as wheat gluten, constitute attractive raw materials for sustainable wood adhesives. In this study, alkaline water dispersions of the protein classes of wheat gluten, glutenin, and gliadin were used as adhesives to bond together wood substrates of beech. The aim of the study is to measure the tensile shear strength of the wood substrates to compare the adhesive performance of glutenin and gliadin and to investigate the influence of application method and penetration of the dispersions into the wood material. A sodium hydroxide solution (0.1M) was used as dispersing and denaturing agent. Dispersions with different protein concentrations and viscosities were used, employing wheat gluten dispersions as references. Two different application methods, a press temperature of 110 C and a press time of 15 min, were employed. The tensile shear strength and water resistance of the wood substrates were compared, using a slightly modified version of the European Standard EN 204. The bond lines of the substrates were examined by optical microscopy to study the penetration and bond-line thickness. The results reveal that the adhesive properties of gliadin are inferior to that of both glutenin and wheat gluten, especially in terms of water resistance. However, the tensile shear strength and the water resistance of gliadin are significantly improved when over-penetration of the protein into the wood material is avoided, rendering the adhesive performance of gliadin equal to that of glutenin and wheat gluten.

“…Wheat gluten is a by-product from the production of wheat starch and bioethanol, and has been studied as a binder for wood adhesives with promising results [34][35][36][37][38][39][40][41][42][43][44]. Other proteins that have been evaluated are, for example, zein protein [45], pea protein [45], canola protein [46,47], cotton-seed protein [47], triticale protein [48], and lupine protein [49,50].…”

Today's society relies heavily on glued wood products for constructions, furniture, and floorings, for example. Essentially, all adhesives on the market are based on fossil-based resources, and many also contain formaldehyde to yield sufficient reactivity and adhesive performance. Formaldehyde is soon to be banned from consumer goods in Europe, due to its carcinogenic and allergenic features. With the rapidly growing societal environmental awareness, it becomes evident that it is crucial to seek greener, more sustainable alternatives. There is nothing new to this idea; on the contrary, prior to the advent of synthetic polymers, a range of biopolymers such as proteins and starch, were successfully used. However, since adhesives based on synthetic polymers were found to perform better, especially regarding the water resistance, the naturally sourced adhesives have had a subordinate role up until recently. The growing interest for using bio-polymers from renewable resources, such as wood/forest, corn, and cereals have spurred significant R&D developments toward the use of bio-polymers in green wood adhesives. The scope of the present chapter is to summarize, in short, some of the most recent scientific literature regarding the development of green adhesives.

Reçu le 26 octobre 2015 -Accepté le 27 mai 2016Résumé -La demande mondiale en produits bio-sourcés en pleine expansion engendre un intérêt croissant pour la recherche de nouvelles ressources de matières premières. Pour générer une valeur économique accrue dans les filières oléo-protéagineuses, les tourteaux, co-produits de l'extraction de l'huile, présentent des qualités pouvant être exploitées dans des secteurs diversifiés. Ces tourteaux sont principalement commercialisés en alimentation animale, mais restent peu utilisés dans le secteur de la chimie ou encore de l'alimentation humaine. Afin d'en étendre les applications, le prétraitement de la matière par broyage et classification granulométrique offre des perspectives technologiques pour la conception de nouveaux procédés d'extraction de composés d'intérêt. Le présent article a pour objectif : d'examiner la pertinence d'une diversification du marché des tourteaux, hors usage traditionnel et dans le secteur de la chimie ; de caractériser la composition chimique des tourteaux ainsi que leurs propriétés techno-fonctionnelles ; d'évaluer la faisabilité de valoriser ces tourteaux ainsi que leurs différentes fractions comme substituts ou additifs permettant la réduction de la teneur en produits d'origine fossile, par exemple, dans la production de formulations adhésives pour les panneaux de particules. Pour ce faire, un certain nombre d'actions ont été menées : évaluation du marché potentiel et accessible à partir des cultures métropolitaines ; analyse du panorama de la propriété intellectuelle pour les marchés identifiés ; caractérisation chimique des tourteaux broyés et de ses fractions solubles et insolubles ; applicabilité des différentes fractions obtenues, en termes de pouvoir moussant, émulsifiant et gélifiant ; premiers tests d'application à partir de tourteaux de colza et de tournesol dans le domaine des panneaux de bois composite. Les résultats obtenus ont permis : de dresser une cartographie de l'activité inventive liée à la valorisation des protéines de tourteaux de soja, colza, tournesol et farine de pois dans des applications variées en mettant en avant le dynamisme et l'intérêt croissant d'industriels et d'universitaires pour l'utilisation des protéines d'origines oléo-protéagineuses ; d'explorer les propriétés techno-fonctionnelles apportées par ces tourteaux broyés et leurs dérivés, en particulier dans les domaines des panneaux de bois composite. Mots clés :Rapeseed / sunflower / ground plant meal / plant protein / lignocellulose Abstract -Ground plant meal potential market, functional properties and applications. The growing demand of bio-sourced products leads to an increasing interest for the development of new resources of raw materials. In order to generate a higher economic value in the oleoproteaginous sector, meals, co-products of oil extraction present qualities capable of being exploited in a wide range of sectors. These meals are mainly commercialized in feed application, but remain relatively weak used in the chemistry domain or even in...
