“…Moreover, the peak around 1450 cm −1 could be attributed to the C=C vibrational mode of the phenyl groups; this is qualitatively confirmed with those deduced from the study of surface functions revealing the notable presence of lactone and phenol functions. While the pronounced peaks around 1000 cm −1 can be attributed to the elongation vibrations of C-O bonds characteristic of alcohols, this peak can also be attributed to the elongation vibrations of Si-O bonds in silica [49]. The peak extending to 860 cm −1 is due to the presence of calcite (CaCO3) [50].…”

The objective of this study is to valorize two waste products which, until now, caused major problems concerning their management and impacts on the environment and health. This study concerns the sludge of the wastewater treatment station of the city of Fez-Morocco and the olive mill wastewater, which are produced, respectively, in quantities of around 51,100 t/year and 514,350 m3/year, by pyrolysis for the production of biochar. The obtained biochar was characterized by physicochemical and spectroscopic analyses. The results show that the biochar is close to neutrality and is characterized by an important organic and mineral load; further, it is endowed with a porous surface, which could facilitate the adsorption of different polluting substances, composed mainly by micropores. It is mainly composed of alcohol, phenol, carboxyl and phenyl groups, as well as other mineral elements including silica and calcite. The composition, structure and morphology of the biochar thus prepared recommend its use in various fields, such as the treatment of pollutants, organic amendment, the reinforcement of polymers and as a secondary building material.

Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae) is a major pest causing substantial economic losses to date palm fruit in southern Tunisia and Algeria, where climatic conditions are very favorable to its development. As part of a study into sustainable management strategies for O. afrasiaticus, two essential oils extracted from Lantana Camara and Ruta chalepensis were tested as adulticides against female O. afrasiaticus mites. For this purpose, an analysis of the chemical composition of these two oils was carried out using the GC-MS method in conjunction with laboratory experiments against fertilised O. afrasiaticus females. The EO of L. camara was mainly composed of caryophyllene (24.33%), Humulene (26.65%) and Muurolene (14.22%). The EO of R. chalepensis was mainly composed of 2-Undecanone (50.52%), 2-Nonanone (11.27%) and 2-Octanol, acetate (9.17%). The acaricidal activity of the EOs against O. afrasiaticus was assessed by contact with females. The LC 50 after 72 h of treatment was 3.198 µL/mL and 8.312 µL/mL for L. Camara and R. chalepensis, respectively. According to the LT 50, the acute toxicity of the EOs to O. afrasiaticus, from high to low, was the Essential Oils L. camara and R. chalepensis at the concentration of 200 µl/ml. In conclusion, the Essential Oils of L. Camara and R. chalepensis have a better acaricidal effect and a high application value for the biological control of O. afrasiaticus, which provides a basis for the development of botanical acaricides.

The present research concerns the development of a new device and process intended for the purification and treatment of sulfurous elements, and more particularly, of hydrogen sulfide (H2S) from the biogas produced at the time of the anaerobic fermentation in the purification stations. The controlled dumps or any other unit are likely to produce biogas with concentrations of H2S harmful to the operation of the machines for the valorization of the produced biogas or deodorization. This device uses new biochar from a mixture of dehydrated digested sludge from sewage treatment plants and margins from traditional crushing units, followed by biological treatment in a liquid medium at a controlled temperature. The liquid medium is based on a margin (nutrient) with culture support (large granules of biochar) in suspension by the injection under the pressure of biogas coming from the biochar filter. Physico-chemical characterization of the biochar and a test practiced on the new device of raw biogas treatment were realized. The results showed that the newly synthesized biochar has a low specific surface and a highly undeveloped porosity. The spectrum corresponding to the images of the biochar reveals the presence of C, O, N, Al, Si, P, and Fe, as significant elements with the following respective percentages: 37.62%, 35.78%, 1.87%, 4.26%, 7.33%, 8.56%, and 4.58%. It is important to note that the C content of the biochar thus synthesized found by EDX is quite comparable to that estimated from ATG. Biogas treatment test results on the prototype object of the invention eliminated 97% of the H2S from the biogas produced.
