This study proposed the development of a nanoscale adsorbent material using waste from Moringa oleifera seeds for the removal of Indigo Carmine from textile effluents. The adsorption process was found to fit the Langmuir isotherm in the equilibrium of adsorption and the power function in the kinetic behavior. The maximum adsorption capacity of the absorbent nanoparticles was significantly higher than that of the bulk Moringa oleifera seeds. The dominant mechanisms of Indigo Carmine adsorption on the nanoparticles were identified as hydrogen bonding, electrostatic interlinkage, and pi-pi interactions. The Moringa oleifera seed nanoparticles showed promise as a green and low-cost adsorbent for textile wastewaters.
The release of Indigo Carmine in waterbodies may cause serious impact in aquatic ecosystems and human health. There is an interest in developing green, low-cost and effective adsorbents for the removal of toxic dyes from textile effluents. This study proposed the developing of an adsorbent material at the nanoscale using the waste from Moringa oleifera seeds generated after the oil extraction. Moringa oleifera seeds were grounded to obtain an adsorbent material at the nanoscale. Batch-adsorption tests were carried out to evaluate the capacity of the absorbent to retain Indigo Carmine from liquid solutions. The following variables were studied: pH, adsorbent-dye ratio, contact time, initial dye concentration and temperature. The adsorption process fitted the Langmuir isotherm in the equilibrium of adsorption and the power function in the kinetic behavior. The maximum adsorption capacity of the absorbent nanoparticles was 60.24 mg/g, which is 4.3 times higher than that of the bulk Moringa oleifera seeds. Thermodynamic results proved the adsorption process was spontaneous and exothermic. Hydrogen bonding, electrostatic interlinkage and pi-pi interactions were identified as the dominant mechanisms of Indigo Carmine adsorption on the nanoparticles. The adsorption-desorption study resulted in a slight decrease of the adsorption capacity after 4 cycles, from 94% to 88%. The removal of Indigo Carmine from a textile effluent (85%) was similar to that with pure Indigo Carmine solutions (91%). The results suggested the feasibility of Moringa oleifera seed nanoparticles as a promising, green and low cost adsorbent for textile wastewaters with dyes.

Olive-mill and grape-mill residue impact the growth, physiology and nutrient status of grapevines young cuttings
Nikolaos Tzortzakis, Antonios Chrysargyris
Summary: The cultivation of olive trees and grapevines in the Mediterranean area has expanded, but the processes that follow harvesting have negative effects on the environment and human health. This study explored the potential use of olive-mill and grape-mill residues in soil, finding that they can provide minerals and organic matter to the mixtures. However, further research is needed to develop the appropriate fertilization scheme.

Environmentally friendly process for phytosterols recovery from residues of biodiesel production.
Renzo Carlucci, Juan A. Arancibia, Guillermo R. Labadie
Summary: Phytosterols, naturally occurring plant sterols, have been found in various plant-based foods and have potential beneficial effects on human health, particularly in reducing the risk of cardiovascular disease. In this study, an efficient method for preparing phytosterols from a by-product of biodiesel production was developed and optimized using an environmentally friendly alternative to traditional mineral acids. The optimized method showed improved yield and offered a greener approach in terms of E factor, energy consumption, and safety. This has important implications for the food and nutraceutical industries, which are increasingly focused on using renewable and eco-friendly sources.

Different ligand functionalized bimetallic (Zr/Ce)UiO-66 as a support for immobilization of phosphotungstic acid with enhanced activity for the esterification of fatty acids

Summary: Different ligand functionalized bimetallic organic framework composites with phosphotungstic acid (HPW) were prepared and used as catalysts for the esterification of methanol with oleic acid. The HPW/(Zr/Ce)UiO-66-NO2 catalyst showed the most promising catalytic features, including the highest number of strong Bronsted and Lewis acid sites, wider pores, higher surface area, and synergistic catalytic effects with the (Zr/Ce)UiO-66-NO2 framework. The catalytic activity of the HPW/(Zr/Ce)UiO-66-NO2 catalyst was higher than other catalysts, and it also exhibited good reusability over multiple cycles.
