In the production process of cellulosic ethanol, all sections are closely related. It is difficult to study its producing law and key factors that affect the process only by experimental means. Computer simulation has a powerful data mining ability, which can analyze, design, and evaluate the production process of cellulosic ethanol. Specifically, it can use data calculated by Aspen Plus before, and analyze the impact of cellulose ethanol production on the environment by life cycle assessment (LCA). Results show that the total environmental impact value of the whole process is 0.20∼0.37 person·a/t. And in the whole process, the growth stage and the production stage have the biggest impact.

L'accumulation de sédiments dans de nombreux barrages construits en Algérie pose un problème préoccupant qui nécessite une attention et une action immédiate de la part des autorités et des gestionnaires de l'Agence Nationale des Barrages et des Transferts (ANBT). De plus, diverses recherches sur les sédiments ont révélé que le fait de les soumettre à un traitement thermique (calcination) permet de les utiliser dans la production de matériaux cimentaires comme substitut partiel au ciment. Additionnés à la perlite, une pouzzolane naturelle, de nombreux avantages peuvent être obtenus, notamment une consommation de ciment réduite, une génération de chaleur minimisée, une maniabilité améliorée, une perméabilité réduite et une résistance accrue. Dans cette étude, l'objectif est d'explorer le potentiel d'utilisation des Les sédiments extraits du barrage Chorfa II ainsi que la perlite provenant de Hammam Boughrara (tous deux situés dans l’ouest algérien) dans le mortier, comme substituts partiels au ciment. Une analyse des sédiments calcinés et de la perlite a révélé la faisabilité d'un remplacement partiel du ciment. Les recherches se sont principalement concentrées sur l'évaluation des propriétés des mortiers à l’état frais et durci.

“…[6] For the sake of environmental protection and in the spirit of sustainable development, it is imperative to find a solution to the problem of massive sediment storage. [27,28] Our work is based on a study of the valorization of these sediments which are found in considerable quantities (that of the Chorfa dam located in western Algeria, commonly called sediment. These materials (after calcination to make them active) find their use in several fields including that of civil engineering as fullfledged components (partly substitutable addition to cement) of cementitious materials.…”

Dam reservoirs are exposed to a loss of water storage capacity due to the phenomenon of siltation. This particularity can be expressed by the siltation of reservoirs and the entrainment of particles transported by watercourses. Siltation of reservoirs is a critical state which causes a reduction in the storage capacity of dams. Algeria is characterized by a semi-arid climate, which annually loses a considerable volume of water storage. The carbonation of concrete is influenced by a number of parameters which accelerate its kinetics. These parameters are the porosity of the concrete, the quantity of lime contained in the cement, the concentration of CO2 in the atmosphere and the humidity of the environment. It should be noted that, water being the vector for moving aggressive agents, carbon dioxide can only diffuse through the concrete if the latter is not completely saturated and not perfectly dry at the same time. Another factor increasing the permeability of concrete is the amount of limestone added to the cement during its manufacture at the factory. This permeability allows the diffusion of CO2 or other aggressive agents in the concrete. The addition of limestone to cement must therefore be used with caution. The objective is to propose economically competitive and easy-to-implement formulations which allow the valorization of these materials in the making of ordinary concrete by partial substitution of cement (10, 20 and 30%) and its influence on the progress of long-term carbonation after six years of curing in the open air. The sediment is treated by calcination at 750°C to make it active. Natural carbonation tests were carried out on the study concretes in order to evaluate their durability. The results obtained confirmed the possibility of producing concretes incorporating calcined sludge at dosages of up to 30% without compromising the quality of these concretes from the point of view of behavior in the face of attacks by the dissolution of carbon dioxide from the air in the interstitial solution of concrete, meeting economic, ecological and technological objectives.
