Hospital liquid effluents in the Casablanca Settat region are marked by the lack of procedures for their management. They are evacuated with large volumes in collective sanitation networks, without prior treatment. These releases contain chemical and pathogenic hazardous substances which constitutes serious threats of pollution and deterioration of populations. This work investigates practices in the management of liquid waste in hospitals in the Casablanca-Settat region. Our methodology is based on 3 investigation methods namely; (a) the questionnaire survey of personnel who directly manage and manage hospital liquid effluents via a questionnaire; (b) also the estimation of the quantity of effluents discharged on the basis of the functional litter capacity of all hospitals the region ; and (c) finally, the systematic analysis of Moroccan articles dealing with the issue of hospital effluents. Among the outstanding results of this study were: (a) the identification of the main deficiencies in terms of effluent management in the Casablanca-Settat region; (b) the enormous quantity of hospital liquid effluents discharged without any prior treatment, (c) the poor quality of hospital liquid effluents in Morocco; (d) Same typology of liquid effluents at

<p class="Mabstract">This study offers an easy, economical, and ecological solution to manufacture a ceramic faience product with excellent mechanical properties by combining Moroccan phosphate mine tailings and two abundant local clays. The use of these clays alone was inconceivable because they do not generate a material that meets the mechanical requirements.</p><p class="Mabstract">A mixture design strategy conducted the optimization of the formulation. Therefore, ten tests were carried out. The ceramic tiles produced are characterized by their physical properties (water absorption, shrinkage), mechanical properties (flexural strength), and surface properties (observation by scanning electron microscopy).</p><p class="Mabstract">The results show that phosphate mine tailings improve the mechanical properties of ceramic tiles. Industrial use at a rate of 33% in formulas based on abundant local clays could, therefore, be envisaged to design faience products, conforming to the mechanical and technical requirements. This mode of production contributes to saving non-renewable natural resources, preserving the environment, and aligns with the principle of sustainable development.</p><div><div><p> </p><p> </p></div></div>

The Casa-Settat region is experiencing very worrying environmental and epidemiological problems and challenges, namely, population growth, the significant development of unsupervised industrial activities, road traffic, the significant weight of the spread of diseases with high epidemiological potential such as SARS-CoV-2, the increase in hospital activities, and the significant discharge of hospital effluents highly contaminated and untreated. To understand and analyze the factors influencing the high prevalence of deaths and the occurrence of diseases under surveillance, among others SARS-CoV-2, on the quantitative data recorded relating to ten regions of Morocco, and informing, on the one hand, on intrinsic data linked to the urban development, and on the other hand, on the evolution of diseases under epidemiological surveillance, a multidimensional analysis was made. The results reveal the typological framework highlighted by the factorial map F1 × F2 which showed the individualization of the region of Casablanca explained by a large number of variables and diseases that affect it. Finally, these results call for a diagnosis that will make it possible to model new approaches and implement new actions promoting the dynamics of environmental and epidemiological change in one of the most polluted and infected regions of Morocco.
