Texto completoThe waste input and the process technology of the plant appear to have a great influence on bottom ash quality. To better understand how these parameters can affect the residues characteristics, bottom ash from 6 different plants were tested and compared in this study. Bottom ash physico-chemical characteristics were investigated by chemical analyses, and leaching tests. In order to understand their long-term behavior, accelerated ageing experiments and biodegradation tests were also performed. The whole analyses gave complementary information. It was shown that the 6 samples do have different properties. Waste input have a great influence on Cl and S content in bottom ash, as well as on the Ca/Si ratio. The importance of this ratio on carbonation process has been demonstrated. Combustion parameters have an influence on quantity and mobility of the residual organic matter. Biological and physicochemical experiments were coupled with a view to developing a new rapid assessment method of bottom ash quality. Comparative results of leaching tests and biodegradation experiments showed a positive correlation between dissolved carbon and microbial activity. However, quantities of biodegraded or leached carbon are not representative of the samples total organic carbon content. Thermal analysis have revealed the presence of two fractions of organic components, showing different thermal behaviors. One of them can be directly linked to the leachable and biodegradable organic matter fraction. Calorimetric test is then a novel analysis method that allows to provide rapid and global information concerning the characteristics of organic matter in bottom ash and its possible short and long-term evolution

Texto completoGeosynthetic Clay Liners (GCL) are factory manufactured hydraulic barriers consisting of bentonite supported by geosynthetics (geotextiles or geomembranes). The last few years Geosynthetic Clay Liners are more and more often used as liners or in capping systems of landfills, as a single or part of a multilayer barrier, with traditional materials ( compacted clay or geomembrane). At the present, in most countries, tests on GCLs are performed using standards for geotextiles and low permeable soils, which are not always easy to adapt to GCLs. In this context, the aim of the presented work is to elaborate adapted devices and testing procedures and to study various GCL products (needlepunched, stitched, containing granular or powder bentonite) in real conditions and in similar manner. Original devices were developed in order to study the Geosynthetic Clay Liners hydraulic behaviour in simulated landfill conditions. They allow performing characterisation and performance tests, as well as to study the chemical compatibility with the leachate. The experimental part is focused on the study of the hydraulic performances of 4 products currently available on the market, in various situations: - in contact with smooth surfaces or granular materials; - in contact with a synthetic leachate, the GCL being dry, partially hydrated or saturated with • water. Tests performed on samples with defects allowed to verify the GCL's selfhealing capacity. The chemical compatibility of bentonite to synthetic leachate are analysed as a function of the degree of initial water saturation and of the type of GCL

Texto completoThe glass used to store high-level radioactive waste is produced by reaction of a solid waste residue and a glassy precursor (glass frit). The waste residue is first dried and calcined (to lose water and nitrogen respectively), then mixed with the glass frit to enable vitrification at high temperature. In order to obtain a good quality glass of constant composition upon cooling, the chemical reactions between the solid precursors must be complete while in the liquid state, to enable incorporation of the radioactive elements into the glassy matrix. The physical and chemical conditions during glass synthesis (e. G. Temperature, relative proportions of frit and calcine, amount of radioactive charge) are typically empirically adjusted to obtain a satisfactory final product. The aim of this work is to provide new insights into the chemical and physical interactions that take place during vitrification and to provide data for a mathematical model that has been developed to simulate the chemical reactions. The consequences of the different chemical reactions that involve solid, liquid and gaseous phases are described (thermal effects, changes in crystal morphology and composition, variations in melt properties and structure). In a first series of experiments, a simplified analogue of the calcine (NaNO3-Al2O3 ± MoO3/Nd2O3) has been studied. In a second series of experiments, the simplified calcines have been reacted with a simplified glass frit (SiO2-Na2O-B2O3-Al2O3) at high temperature. The results show that crystallization of the calcine may take place before interaction with the glass frit, but that the reactivity with the glass at high temperature is a function of the nature and stoichiometry of the crystalline phases which form at low temperature. The results also highlight how the mixing of the starting materials, the physical properties of the frit (viscosity, glass transition temperature) and the Na2O/Al2O3 of the calcine but also its crystallization all contribute to the success of the vitrification process and the homogeneity of the final glass

Texto completoThe first part of this work concerns the monitoring of treated olive mill waste water (OMWW) transformations during biological and chemical processes : different physico-chemical parameters (pH, C/N ratio, chemical oxygen demand (COD), level of total phenols and lipids) and spectroscopic analysis (UV-Visible, IRTF, 13C-NMR). The results of the biological treatment permitted us to determine the optimal conditions of OMWW treatment. After 45 days, the treatment decreased the COD, particularly for treatments without lime with a drop of 21. 8% while the COD drop in treatments with lime only reached 4. 8%. Neutralising the pH by the addition of lime had a positive effect on the degradation of total phenols, lowering their levels by 75. 9%. The results of FTIR and 13C-NMR spectroscopy showed that during treatment with lime, the aliphatic groups decreased and the aromatic structures increased, indicating polymerisation of the organic matter. The lipid content showed an appreciable change in the relation to the applied treatment both for total lipids and for the lipidic fractions (neutral lipids, monoglycerides and phospholipids). Total lipid increased for treatment without lime and decreased for treatment with lime, corresponding to the variation in the level of phospholipids. 13C-NMR confirmed these variations and showed the likeness between the treatment of the OMWW with lime and the treatment with solvent (chloroform/methanol). The main spectral differences were observed in the C O-Alkyl region (50 -110 ppm) and in the C-carboxylic region (160-200 ppm). The results of the chemical treatment using TiO2 under UV showed depollution of the OMWW. Over 24 hours, the treatment degraded 22. 2% of the pollutant COD, 57% of the coloured molecules (UV to 330 nm) and 94. 3% of the total phenols. The UV-Visible and FTIR spectroscopy showed extensive attack of the aromatic structures and revealed the occurrence of three successive phases during the degradation process, thought to correspond to three different categories of molecules in the OMWW. The second part of this work concerns the study of the toxicity and the genotoxicity of OMWW after biological treatment, on Vicia faba plants, by micronucleus and agronomic tests. The results of the micronucleus test showed that raw OMWW was genotoxic at a 10% OMWW concentration. This genotoxicity was associated to two phenolic compounds: gallic acid and oleuropein. After biological treatment, the genotoxicity disappeared at a 20% OMWW concentration. This can be explained by the extensive degradation of phenols during the treatment (75. 9%). The agronomic test showed the absence of toxicity of treated OMWW on Vicia faba plants. Indeed, at doses of 5 t/ha and 10 t/ha outputs were 36. 3% and 29. 9% greater than the negative control respectively. OMWW treated by a biological process do not present any risk of toxicity or genotoxicity on Vicia faba plants, the treated effluent can be used, without risk, as organic amendment on Moroccan soils

Texto completoIn this thesis we have taken advantage of catalysis for the development of new fuels, limiting the accumulation of waste during the selective activation of new chemical systems. In a first part, we transposed the principle of reversible hydrogenation reactions to the field of molecular machines. This approach has allowed the development of a tolane-type molecular switch operating during two consecutive de/hydrogenation cycles. This represents the first system powered by chemical fuel without any waste production. We have also extended the use of trichloroacetic acid (TCA), for the development of new self-assembly systems and in particular time-controlled organogels. Thus, starting from a natural amino acid derivative (O-tert-Butyl-L-tyrosine), we were able to develop two complementary systems allowing a gel-sol-gel or sol-gel-sol transition. We were able to perform 11 consecutive gel-sol-gel cycles, and more than 25 consecutive sol-gel-sol cycles before having to regenerate the system by simple evaporation. This strategy could be extended to octadecylamine with which we performed 12 consecutive gel-sol-gel cycles. It is important to note that both gel-sol-gel and sol-gel-sol systems based on O-tert-Butyl-L-tyrosine, have unique chiroptical properties. Finally, we set out to develop hybrid systems capable of responding to two different stimuli, hydrogen and TCA. Based on phenanthridine backbones, they allow a controlled rotation in response to these two types of stimuli

Texto completoThe first part of this thesis is a market study of the availability of recycled wood. Each year, in France, 16 million tons of wood waste are collected by specialist companies and waste reception centres. Less than 14% of this is recycled, partially because regulations do not allow highly contaminated wood resources and also because of inadequate sorting techniques, which are often limited to visual assessment. Clearly, recycled wood should be analysed chemically. European standards DD CEN/TS 14778-1:2005 and DD CEN/TS 14780:2005 describe how to obtain samples weighing tens of kg from stockpiles of hundreds of tons. The particles in the sample, often with a top size of several centimetres, must be ground to a fine flour of less than 500 µm. It is impractical to grind the whole sample and so a robust protocol which permits sub-sampling without introducing bias is necessary. A model sample of recycled wood was created using clean particles impregnated with different metals. Different sub-sampling protocols were applied to this model. The samples were analysed chemically in order to see differences via statistical analysis. Standard wet chemistry methods and analyses (ICP-AES and AAS) were used to measure metal contents. In addition, a potentially non-destructive technique based on Fourier Transform Near Infrared Spectroscopy (FT-NIRS) was used to characterize and to predict the presence of metals in wood samples. Multivariate statistical techniques permit the discrimination between particles containing different metals or organic preservatives. It is demonstrated that the level of contamination, particularly with copper slats, can be determined by comparing observations with a database of spectra obtained from known samples (PLS modelling)

Texto completoThe Tournemire (France) site has been selected for research programmes on deep geological waste disposal in clay-rich rock formation. A railway tunnel is used to study the evolution of rock properties and water-rock interactions in the excavated disturbed zone. Multi-scale and multi-technique investigations were carried out. Experiments and numerical modelling were used to predict changes due to rock mineralogy and water chemistry modifications. The tunnel and galleries digging induces fracture formation. In the altered samples, the clay particles show a better orientation in the stratification plan. The oxidation effect yields to mineralogical transformation on the surfaces of the argillite: oxidation of pyrite, dissolution of calcite, dissolution of illite layers in interstratified I/S and formation of gypsum, Fe-oxi/hydroxides, celestite and jarosite. During cycles of hydration/dehydration, condensation water interacts with the argillite and quickly becomes Ca and SO4-rich
