Extraction processes involving hemicellulose from barley bran and straw have garnered significant attention in recent literature, primarily due to their implications for the sustainable utilization of agricultural residues. In this meticulously crafted investigation, the salient application of process simulation techniques is foregrounded, delineating the profound effects of diverse operating...
Heavy metal contamination has harmful consequences for the ecosystem. They are naturally non-biodegradable, and can cause severe ecotoxicity and numerous pathologies. Several techniques have been used for metal pollution control. The aim of the present work is to exploit the rearing waste of the Black Soldier Fly Hermetia illucens (pupal stage) to produce chitin and its derivative chitosan,...
This study aims to increase the solar energy conversion into electrical energy by integrating two different systems, namely the photovoltaic system PV and the thermoelectric generator TEG. The thermoelectric generator will convert by Seebeck effect the thermal energy produced by the photovoltaic panel which will add additional electrical power to the overall power. A comparison between the...
This study revolves around two main parts. First, we conducted an assessment of Bias-adjusted Euro-Cordex simulations to examine their capability to reproduce the thermal and precipitation characteristics, both in terms of mean and extreme values, at the local scale of Morocco. This assessment was performed in comparison to data obtained from observations at weather stations and ERA5...
Over the past 50 years, West Africa has experienced one of the greatest variations in rainfall observed on a global scale. These climatic fluctuations not only affected the precipitation regime but also had consequences on hydrological and plant resources. As a first approach, climatology is interested in the average values of meteorological parameters, their dispersion around this average,...
Wastewater treatment plants (WWTPs) provide optimal conditions for the maintenance and spread of antibiotic-resistant bacteria. In this work, we describe the occurrence of antibiotic-resistant fecal coliforms in the inlet and the outlet of WWTPs in Settat City Morocco. This leads us to identify the role of WWTPs in the dissemination and the spread of antimicrobial-resistant Enterobacteriaceae...
The objective of the current study was to evaluate the nutritional value of tomato by-products on chickens. A total of 150 broiler chicks were randomly divided into groups of 15 pens and fed with standard diets supplemented with different percentages of tomato by-products (5%, 10% and 15%) for 39 days. The control group was fed only with standard diets under the same conditions as the treated...
Climate change and socio-economic development will have important implications on the long-term sustainability of natural resources supporting the human and ecological systems globally. These impacts also interact in complex and non-linear ways that transcend beyond traditional sectoral ad regional boundaries with cascading and potentially pervasive implications. This is particularly relevant...
North African nations, including Morocco, face increasing vulnerabilities due to global warming and rising electricity demand, driven by heavy dependence on imported fossil fuels. This dependency poses threats to both energy security and economic stability.
The adoption of nuclear energy in Morocco could serve as a viable and strategic alternative to address the country's growing...
Addressing the global spike in organic waste, worsened by rising agricultural operations, is critical in the context of escalating environmental issues. The danger of non-point source contamination grows with improper handling of organic waste. This study emphasizes the need of thorough monitoring as a remedy across the composting process. This research focuses on organic waste management,...
The aim of this work is the investigation of a natural organic coagulant for the pretreatment of olive oil mill wastewater (OMW), aiming to replace conventional metal-based coagulants. The goal was to produce healthy OMW that could potentially be reused in several fields of application such as pharmaceuticals and cosmetics. Chitosan was selected as a model natural organic coagulant, and the...
Grapevine (Vitis vinifera L.) is a highly significant perennial plant with more than 6.95 million hectares of vineyards worldwide, producing table grapes, wine grapes, and derivatives. Wine production alone generated a global market value of over 29 billion euros in 2020. Morocco ranks fourth among major grapevine-producing countries, with a vineyard area of 42,286 hectares. Crown gall (CG),...
Industrially, the amount of chitinous waste based on cuttlebone discarded annually in some coastal areas of Morocco is considerable and harmful, is about 1,732, 034 tons. This biological waste constitutes a potential source of active biomolecules such as chitin, chitosan and aragonite. Interest in these natural resources is limited to fishing, and waste is dumped on the coast. In the present...
The utilization of Plant Growth-Promoting Rhizobacteria (PGPR) has shown significant potential in mitigating the adverse effects of salt stress on the growth of date palm trees in saline environments. These beneficial microorganisms enhance the plant's ability to tolerate and adapt to high salt concentrations by stimulating root growth, improving nutrient uptake, and facilitating the synthesis...
