Opis:: Future options for addressing the depletion of fossil fuels and reducing pollution from internal combustion engines may include biofuel as an alternative fuel. This study aims to experimentally and statistically assess the effect of using diesel-biofuel blends on the emissions of a single-cylinder direct-injection engine. Using recycled olive oil, a chemical Tran’s esterification process was used to create biofuel. The experimental results were contrasted with those of a one-dimensional engine model for exhaust emissions and torque, which showed high agreement between test and numerical data. In order to comprehend the factors that affect the engine’s reaction to variations in fuel composition, the thermodynamic characteristics of the engine for various blends were also supplied. According to the investigation, a mixture with 20% of the volume fraction of oleic acid methyl ester olive-based biofuel and 80% of the volume fraction of pure diesel can be an effective fuel alternative for cleaner exhaust emissions while offering almost the same performance.

Opis:: The olive mill wastewater, effluents from the trituration of olives, are treated in most Mediterranean countries by natural evaporation. However, this method of treatment is a source of air and soil pollution by the generation of solid waste, called olive mill waste cake. This work focused on extracting of vegetable oil from this by-product for biodiesel production by transesterification. The extraction took place with a Soxhlet extractor, using hexane as solvent. The vegetable oil and biodiesel were characterized by measuring the physicochemical parameters that identify them according to AFNOR standards. The extraction results show that the oil yield is 21.28%. The oil obtained is characterized by density, water and ash content, acidity, saponification, peroxide and ester. The yield of the oil esterification reaction is 86.41% or about 185 Kg of biodiesel/ton of olive mill waste cake, and in terms of energy 2783.7 MJ or 2 GW.t-1. The biodiesel produced is comparable to petroleum diesel according to EN 14214, 2013.

Opis:: Olive mill wastewaters represent a severe environmental problem, especially in Mediterranean countries. Indeed, the treatment and recovery processes developed so far remain very limited and their cost is very high. However, treatment by shallow evaporation ponds in the open air remains, until now, the most used technique despite the efforts made. The volume and characteristics of this liquid effluent depend, among other things, on the nature of the extraction process used. In this context, this work aims to evaluate the effect of the mode of trituration and storage in the evaporation ponds on the quality of olive oil mill wastewaters. These effluents were collected from three olive mills located in two different provinces in Northern Morocco during the 2021–2022 olive growing season. The sampling has considered different points according to different steps of the process. The analytical work corresponded to the measurement of in-situ parameters (Temperature (T°), Dissolved Oxygen (DO), Electrical Conductivity (EC) and pH degree (pH)) and other laboratory analysis (Suspension Matter (SM), Dry Matter (DM), Fatty Matter (FM), biochemical (BOD5) and chemical (COD)demands in oxygen). Results showed a high degree of environmental degradation. Indeed, these effluents are characterized, on average, by elevated concentrations of biological and chemical oxygen demands and suspended solids reaching up to 0.43 g/L ± 0.87, 1.69 g/L ±0.71 and 30.78 g/L ±25.1, respectively. This study also showed, except for two-phase olive mill BNANDA, a slightly alkaline nature of the vegetable waters (7.81<pH<8.52), as opposed to what was reported in the literature, and high levels in fat content (4.73 g/L ±3.85). Moreover, the estimated volume of vegetable water released in the study area during the 2019/2020 olive growing season (350×10³ m³) is very high considering its equivalence to domestic water. Normalized Principal Component Analysis (ACPN) and Hierarchical Principal Component Classification (HCPC) indicate that differences in the composition of this wastewater were more pronounced between the extraction processes than by the origins of the vegetable waters (fresh or stored in the natural evaporation pond).
