The valorization of plant waste, so abundant in Morocco, offers great potential for the development of a new sector of composite materials. Nevertheless, this potential remains under-exploited. In this context, this study was carried out to investigate the thermal and acoustical characteristics of local composite panels based on plant fibers. The aim is twofold: on the one hand, to offer an alternative solution to waste management in Morocco, and on the other hand, to improve the thermal and acoustic performance of walls.Several samples of composite materials based on plant fibers (wood chips, sawdust, crushed hemp shiv, and fibred hemp shiv) were developed to assess their thermal and acoustical characteristics.From a thermal point of view, the experimental results have shown that the majority of composites studied exhibit low values of the thermal conductivity and diffusivity. In addition, the variation in bulk density has a considerable effect on the thermal properties of the composites. In addition, the thermal inertia parameters of the exterior wall are influenced by the thermophysical properties, thickness, and position of the insulation in the wall, as well as the internal global heat exchange coefficient.From an acoustic point of view, the samples have a significant acoustic absorption capacity, particularly at high frequencies. They can absorb more than 50% of incident sound energy over a wide range of frequencies. Composite bulk density and particle size also influence acoustic absorption.In conclusion, the results obtained provide a reliable and promising assessment of the thermal and acoustic performance of plant-based insulation materials. The development of this sector will contribute to Morocco's energy efficiency development program and enrich the database of insulation materials available in the country

The aim of the proposed research was to provide a better understanding of the mechanisms of biomass torrefaction and to propose practical methods to improve the efficiency of this process. As for the mechanism, torrefaction of two woody biomass samples from Quebec forests (aspen and birch) and their main constituents, i.e., lignin, cellulose and hemicellulose is studied in details using different experimental techniques and a kinetic model is developed for their torrefaction. Our studies on the mechanism and kinetics of biomass torrefaction also revealed the slow rate of biomass torrefaction which motivated us to propose and develop a new ionic-liquid assisted torrefaction process with the aim of increasing the rate of biomass torrefaction. Although torrefaction improves the physicochemical properties of biomass fuel, release of oxygenated hydrocarbons (in the form of volatiles) from biomass reduces its overall energy. To recover volatiles energy, a new combination of biomass torrefaction and chemical looping volatiles combustion was studied. In this regard, the already comminuted, abundant and cheap iron and magnesium bearing silicate minerals found widely in the form of mining residues in the province of Quebec were tested as solid oxygen carrier and up to 96% of volatiles conversion at 700°C was achieved in CLC reactor. As a supplementary work, we were also interested to explore the potential of mining residues containing sizeable quantities of iron for catalytic cracking of tar released during the gasification of biomass. For this purpose, iron-bearing mining residues and minerals obtained from the mining activities in Quebec were evaluated comparatively to olivine (known as an active mineral for tar cracking) for benzene cracking in simulated syngas. It was found that chrysotile showed up to four-fold increase in benzene and methane conversion than olivine.

The work in this thesis has tried to improve the characteristics of aminoplastic and phenolic resins used to make wood particleboard and plywood. To achieve this a number of different additives, active extenders and fillers have been added to the resins. These were polymeric diphenylmethane diisocyanate (pMDI), micronized waste polyurethane (PUR) powders, a protein namely albumin, a number of fluorinated polyethers (PolyFox) and urea-formaldehyde (UF) polycondensates in which part of the formaldehyde was substituted with propionaldehyde to form urea (formaldehyde-propionaldehyde (UFP) resins. The totality of the formulations and methodologies used for the preparation of the resins is presented in this thesis. Four types of laboratory resins have been synthetised: UF (Urea-Formaldehyde), PF (Phenol-Formaldehyde), UFP (Urea-Formaldehyde-Propionaldehyde) and UP (Urea-Propionaldehyde). Two commercial UF resins have also been used. All the resins were analysed by 13C NMR, gel permeation chromatography (GPC), thermomechanical analysis (TMA) and infrared spectrometry (FT-IR). The plywood and wood particleboard were prepared with the different glue-mixes, and tested according to the specifications of the relevant European Norms. Some of the panels were also analysed by X-ray microdensitometry and MEB

This work aims to substitute resins based on formaldehyde as UF by “green” thermosetting adhesives based on natural and renewable local products, in the wood composite industry. The resins studied in this thesis are made from local resources (dextrins from corn starch and tannins from maritime pine barks) and must respect certain industrial requirements. To meet these industrial constraints, the research work of this manuscript deals with studies ranging from the structural understanding of basic product mixtures, up to the characterization of the properties of panels manufactured in the lab, including the formulation and reticulation of resins. These studies show that it is necessary to work in an alkaline medium to solubilize the tannins. In this situation, the tannins / dextrin mixtures give colloidal suspensions. The mass fractions in tannins and dextrins allowing to obtain parameters respecting the specifications vary from 0 to 40%. The epichlorohydrin has been used as hardener to cross-link these resins. Thermosetting materials with good dimensional stability have been obtained. However the resin swelling depends on the composition of the formulation. Adhesive, mechanical and thermal properties of these materials were characterized. Thus, adhesive formulations with the best thermomechanical performances have been selected. Finally, composites have been made from these adhesives and wood particles, respecting an industrial procedure. It has been shown that these panels and those obtained with UF adhesives have equivalent mechanical performances
