Membrane process is a viable option for valuable compounds such as lignin and lignans recovery in aqueous discharges of thermomechanical pulp industries. Recovery of lignin and lignans with continuous mode ultrafiltration/nanofiltration installation has not been studied in detail previously. After flotation used to remove lipophilic matter of pulp mill effluent, the three steps membrane process was composed of a clarification step by a 150 kDa ultrafiltration used to remove suspended matter, followed by two nanofiltrations of 1 kDa and 300 Da to respectively retain lignin and lignans. A techno-economic evaluation of this process has been performed. The process with a plant capacity of 60 m(3) h(-1) was able to produce 12 tons of lignin and 825 kg of lignans per month. The influence of plant capacity between 0.1 and 60 m(3) h(-1) on extracts production cost allows determining a production cost equal or below 10 V.kg(-1) as plant capacity reached 10 m(3) h(-1). Valorization of lignin and lignans as parts of the formulas of high added value products could allow thermomechanical plants to head towards biorefinery and cleaner production concepts. Furthemore, the 300 Da permeate possessed the required characteristics to be re used and save fresh water utilization.

Three different types of lignin (kraft, organosolv and phosphoric acid lignin) were characterized and tested as precursors of electrospun nanofibers. Polyethylene oxide (PEO) was added as a plasticizer and dimethyl formamide (DMF) employed as a solvent. It was found that the molecular weight of lignin was the key parameter to understand the differences of the mechanical stability of the resultant fiber mats. In the case of kraft lignin (KL), the influence of some changes in the synthetic process was also tested: applied voltage, pretreatment in air or not, and the addition of a small amount of Ketjen black. After pyrolysis in nitrogen flow, the obtained carbon nanofibers (CNFs) were characterized by different techniques to analyze their differences in morphology and surface chemistry. Vanadium electrochemistry in 3M sulfuric acid was used to evaluate the different CNFs. All fibers allowed electrochemical reactions, but we observed that the oxidation of V(II) to V(III) was very sensitive to the nature of the raw material. Materials prepared from kraft and phosphorus lignin showed the best performances. Nevertheless, when 1 wt.\% of Ketjen black was added to KL during the electrospinning, the electrochemical performance of the sample was significantly improved and all targeted reactions for an all-vanadium redox flow battery were observed. Therefore, in this work, we demonstrated that CNFs obtained by the electrospinning of lignin can be employed as electrodes for vanadium electrochemistry, and their properties can be tuned to improve their electrochemical properties.

In order to investigate the effect of potassium addition on the composition of torrefaction condensates, two demineralized wood species were impregnated with different concentrations of K2CO3 and then torrefied at 275 degrees C up to an anhydrous weight loss (AWL) of 25\%. Torrefaction was carried out in both a thermogravimetric analysis (TGA) instrument and a laboratory fixed-bed reactor. Condensates from the fixed bed reactor were collected and analyzed by Gas Chromatography-Mass Spectroscopy (GC-MS). TGA of raw and K2CO3-impregnated biopolymers (cellulose, xylan and lignin) were performed to facilitate interpretation of the results. TGA showed that when potassium content increased in the biomass, shorter torrefaction times were sufficient to obtain the targeted AWL. GC-MS showed, for both wood species, that potassium promotes the formation of acetol and slightly enhances acetic acid yield. The amount of some lignin derivatives (guaiacol, syringol, 4-vinylguaiacol) also rose with potassium addition. Yields of levoglucosan, LAC (1-hydroxy-(1R)-3,6-dioxabicyclo [3.2.1]octan-2-one) and DGP (1,4:3,6-dianhydro-alpha-D-glucopyranose), as well as furfural and 5-hydroxymethylfurfural, decreased drastically in the presence of potassium. In conclusion, small additions of potassium carbonate deeply affected thermal degradation of wood species and the speciation of torrefaction condensates.

Tannins are food additives widely used due to their antioxidant and antimicrobial activities, and flavouring properties. Nevertheless, the information provided by the manufacturers are often generic, and data on the presence of specific phenolic compounds and potentially toxic elements are needed. In this work a selection of food-grade plant extracts - also called \&$\#$39;commercial tannins\&$\#$39; - from different botanical sources: Vitis vinifera sp., Camellia Sinensis, Quercus robur, were profiled using UV-vis spectrophotometry, matrix-assisted laser desorption/ionization-time-of-flight-mass spectrometry (MALDI-TOF-MS), and inductively coupled plasma-mass spectrometry (ICP-MS). The combined analytical approach was suitable for quality control of the polyphenolic fraction to highlight authenticity markers (e.g. galloylated flavonoids, glycosides, ellagitannins), and to ascertain the content of toxic elements (Cu, Sr, As, Co, Cr, Fe, Zn, Li, Ba and Pb) respect to their legal and/or recommended limits.

This study proposes a model using data from a scanner (X-ray and grain angle measurements) to perform strength grading. The research also includes global measurements of modulus of elasticity (obtained by vibrations and ultrasound methods), static bending stiffness and bending strength of 805 boards of Douglas fir and 437 boards of spruce. This model can be used in an industrial context since it requires low computational time. The results of this study show that the developed model gives better results than the global non-destructive measurements of the elastic modulus commonly used in the industry. It also shows that this improvement is particularly higher in the case of Douglas fir than for spruce. The comparison has been made on both the quality of the mechanical properties assessment and on the improvement of the grading process according to the European standards by using different index.

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 food. To enlarge these applications, the pre-treatment of the raw material by grinding and air-classification offers technological outlooks for the conception of new extraction processes of interesting components. The present publication has the following goal: to examine the diversification of oleoproteaginous meal market, out of traditional usage in the chemistry domain; to characterize the meals chemical composition and their techno-functional properties; to evaluate the feasibility of valorizing these meals and their derivatives as substitutes or additives allowing the reduction of the level in petro-chemical product, for example, for the production of adhesive formulations for particle boards. To achieve this, different actions have been performed: evaluation of the potential and accessible market starting from metropolitan crops; analysis of the panorama of intellectual property for the identified markets; chemical characterization of ground plant meals and their soluble and insoluble fractions; applicability of the different obtained fractions, in terms of foaming power, emulsifier and gelifier; first application tests starting from rapeseed and sunflower meals in the wood panel board domain. The obtained results have allowed: to draw up a map of the inventive activity bound to the valorization of proteins from rapeseed, sunflower and soy meals and pea flour in various applications, highlighting the dynamism and the growing interest for industrials and academics to use oleo-proteaginous plant proteins; to explore techno-functional properties brought by these plant meals and their derivatives, in particular in the wood panel domain.

Tannin of chestnut (Castanea sativa Mill.) wood, commonly used in winemaking was characterised with a spectroscopy qualitative approach that revealed its phenolic composition: several vibrational diagnostic bands assigned using the Attenuated Total Reflectance-Infrared Spectroscopy, and fragmentation patterns obtained using the Laser-Desorption-Ionization Time-of-Flight technique evidenced polygalloylglucose, e.g. castalagin/vescalagin-like structures as the most representative molecules, together with sugar moieties. The implication of these findings on winemaking application and the potential influence of the chemical structure on the sensory properties of wine are discussed.

Timber strength grading has become a major issue in the European Union during the last years, due to the introduction of the Eurocode 5 and all its related standards. Currently, the most performing strength grading machines are able to locally detect the boards\&$\#$39; knots sizes and positions and interpret this information through adapted grading models. The best lead to improve their accuracy seems to be the introduction of new information about the boards and adapt the mechanical model to take them in account. Small grain angle causes high reduction of clear wood\&$\#$39;s mechanical properties; local value of slope of grain appears to be of high interest. The aim of this study is to quantify the additional accuracy that grain angle information can bring to an optical scanner used as a strength grading machine. A specific grading model has been developed accordingly, and the results obtained for different machine/model/loading combinations are presented. These results show that slope of grain measurement can significantly improve the accuracy of the optical scanner, for both modulus of elasticity and modulus of rupture estimations.

Condensed flavonoid tannins from Maritime Pine (Pious pinaster), Mimosa (Acacia mearnsii), and Radiata Pine barks, and Quebracho (Schinopsis lorentzii and balansae) wood, were first reacted with dimethyl carbonate. Then hexamethylenediamine was added to these mixtures to form urethane linkages. The resulting materials were analyzed by Fourier transform infrared (FTIR) spectroscopy, matrix assisted laser desorption ionization time of flight (MALDI-TOF) mass spectrometry, gel permeation chromatography (GPC), and thermogravimetric analysis (TGA). Finally the resulting analysis indicated that the products obtained are polyurethanes. Initial wood coating applications tests were carried out under conditions of higher temperature and some pressure, and the contact angle of the surface coatings so prepared was measured.
