Texto completoLike other European countries, France is currently mobilizing for the energy recovery of its agricultural wastes by anaerobic digestion. Nevertheless, the production of these resources undergoes several fluctuations throughout the year. Consequently, in order to allow the continuous supply of biogas plants, these raw materials must be often stored for long periods (several months). This thesis focuses on the optimization of agricultural wastes management practices before anaerobic digestion. Different storage conditions were studied, notably the open-air storage and ensiling, with the aim of improving the conservation of the biochemical methane potential and optimizing the conversion of organic matter during anaerobic digestion. An original experimental methodology was developed and implemented for the multiphasic characterization of biomass at different stages of its management and storage, including analysis on the different biochemical fractions and bioavailability of carbon for anaerobic digestion. First, this methodology was applied to the preparation and long-term storage of catch crops. This evidenced a major advantage of using ensiling rather than open-air storage for the preservation of biomass and methane potential. Second, long-term storage trials were conducted for cattle manure. These experiments highlighted the poor conservation of manure and the benefits of co-substrates in the improvement of storage performances under ensiling conditions. To explain the major mechanisms that occur during the ensiling process, a modelling approach was used to synthesize and interpret the results. Finally, this research work led to the identification of good conservation practices for the major feedstocks of agricultural biogas plants

Texto completoBorn out of misery, agricultural co-operatives have been walking hand in hand with farrners through economie, political and societal changes since the beginning of the 20th century.. Economie tool designed tofulfill the development of their members and their territories, they never stopped proving their capacities to adapt. However, their political model involving members to the decision-making process had suffered from changes such as diversification, the establishment of subsidiaries, the opening to non-co-operative partners.The place of members has to be reassessed, their loyalty being an undeniable asset for the co-op.This study is based upon the analysis of the minutes of the general assemblies of five agricultural coops.It aims at making history an asset in the management of the members: by building knowledge, history can feed communication towards members. Finally, it is proposed to carry out this research in a co-operative way so as to pool resources

Texto completoThe aim of this study was the valorization of industrial by products (fly ash) or agricol wastes (rice husk ash) in the cement industry. The principal objective was to determine a durable and economical binder containing the highest amount of by-product. The pozzolanique activity of these blend was studied using physicochemical methods-conductimetry, thermal analysis, x-ray diffraction, I-R spectrometry, scanning electron microscopy, mercury porosimetry and mechanical test. The use of rice husk ash led to the maximum consumption of lime whereas the best strength were obtained with fly ash blended cements. The kinetics of reactivity are different : a good activity at early ages for the rice husk ash and more progressive action of fly ash. Mortars cast with these blended cement were placed in aggressive solutions. The results showed that 30 to 50% fly ash blend can be used when the solution is meanly aggressive. In high chloride solution a 50% rice husk ash blend gave good results

Texto completoBiocatalytic extrusion, also named bioextrusion, is a reactive extrusion technique using enzymes as catalysts. Bioextrusion is considered as a link between the previous physico-chemical pretreatment (like alkaline extrusion) and the subsequent enzymatic hydrolysis in batch conditions. The extrusion allows a continuous, flexible and versatile process for high consistency media, easily transferable to the industrial level. However, complexity of both lignocellulosic biomass and lignocellulolytic enzymes and their interactions during the extrusion process are underlined by the literature. Numerous response surface methodology experiments with starchy biomass indicate that bioextrusion efficiency is mainly influenced by substrate and enzymes loading. Enzymatic activity during the bioextrusion process of lignocellulosic biomass is confirmed by the experiments despite the mechanical constraints and the limited residence time. During bioextrusion, best holocellulosic fraction hydrolysis results were obtained with high substrate and enzymes loadings. Significant modifications of the solid fraction like particule size reduction, visual deconstruction of the biomass structure, increased sensibility to thermal decomposition and the evolution of the surface exposure of crystalline and amorphous cellulose were observed. Enzymatic hydrolysis of the bioextrdates is prolonged in batch conditions. Clear improvements of speeds and rates of sugars conversion up to 48 h indicate a long term influence of the bioextrusion. Gain observed are steady for the pretreated wheat straw whereas it increases with time for corn residues and birch barks. Post-extrusion, a negative influence of the substrate loading is measured. However, best enhancements for the glucose conversion of pretreated wheat straw are detected for high substrate and enzymes loadings. From 4 to 48 h, significant losses in xylose conversion are measured with previous bioextrusion. Indicators of the solid fraction deconstruction, observed during the bioextrusion step, indicate a stronger biomass degradation after 48 h. Improvements of glucose conversion rates can be associated with good mixing conditions of the extruder, especially due to the use of kneading elements. Enzymes are probably more homogeneously distributed (distributive mixing) and can access more catalytic sites available. Moreover, dispersive mixing limits the enzyme jamming due to the biocatalysts concentration. Extrusion process permits an better agitation efficiency, good mass transfer conditions and probably a higher contact between substrate and enzymes. Lower xylose conversion results may be attributed to non-specific adsorptions or inactivation phenomena due to mechanical constraints and lignin residues. Good deconstruction results on the solid fraction may be associable with a synergetic action between mechanical and biochemical constraints. Autofluorescent signal analysis of the lignin fraction show its evolution during the deconstruction of the solid residue. During the hydrolysis, a progressive production of very small particles, appearing to be associated with the lignin fraction is observed. Lignin-carbohydrate complexes are also detected in the liquid fraction. These heteropolymeric complexes, difficult or even impossible for the enzymes to hydrolyze, are an obstacle to the biomass valorization. If lignin deconstruction is mainly due to the alkaline pretreatment, bioextrusion process seems to reduce the proportion of these heteropylymers with high molecular weights
