Abstract This study addresses the pressing issue of environmental pollution caused by antibiotics and synthetic dyes in aquatic ecosystems, presenting a novel approach for their efficient photocatalytic degradation. Zinc oxide (ZnO)-based nanoscale photocatalysts, including ZnO nanoparticles (NPs) ZnO/Ag nanocomposite heterostructure (NCH), were synthesized through an innovative eco-friendly method utilizing extract derived from discarded lemon peels as biogenic reducing agent. The materials extensively characterized UV spectrophotometry, X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR). results confirmed different morphologies NPs NCH, with average sizes 20 nm 42 nm, respectively. Notably, NCH exhibited optical bandgap energies 3.2 eV 2.85 eV, respectively, signifying potential photocatalysts. Under natural sunlight irradiation, these demonstrated exceptional activity, achieving remarkable 98.8 % degradation rate metronidazole 90 ciprofloxacin just 12 min. Furthermore, effectively removed 84 Toluidine Blue 77 Congo red after 120 min, while enhanced rates to approximately 90.5 86 Red. research highlights significant physicochemical properties synthesis methods employed, positioning sustainable nanomaterials promising solutions mitigating effectively.

In the last decades, evidence has indicated beneficial properties of dietary polyphenols. vitro and in vivo studies support that regular intake these compounds may be a strategy to reduce risks some chronic non-communicable diseases. Despite their properties, they are poorly bioavailable compounds. Thus, main objective this review is explore how nanotechnology improves human health while reducing environmental impacts with sustainable use vegetable residues, from extraction development functional foods supplements. This extensive literature discusses different based on application stabilize polyphenolic maintain physical–chemical stability. Food industries commonly generate significant amount solid waste. Exploring bioactive waste been considered line emerging global sustainability needs. Nanotechnology can an efficient tool overcome challenge molecular instability, especially using polysaccharides such as pectin assembling material. Complex biomaterials extracted citrus apple peels (from juice industries) constitute promising wall material stabilizing chemically sensitive Pectin excellent biomaterial form nanostructures, it low toxicity, biocompatible, resistant enzymes. The potential polyphenols residues inclusion food supplements possible constitutes approach for effectively including diet.

Food waste and by-products have attracted attention in recent years due to the reduction of food resources negative impact on environment current production consumption systems. However, can be transformed into new products that useful for human because they represent a source nutritional technological (e.g., preservative, colorant, fibres) added-value compounds. Those compounds interest extracted using several advanced and/or emerging extraction techniques, which follow green chemistry principles, incorporated products. This is true many types foods; even dairy cheese one most appreciated consumed worldwide. Therefore, effective vehicles valorization. review focuses opportunities valuing various wastes sector, especially cheese. It also highlights contributions recovered bioactive enhancing nutritional, technological, sensory properties expected could used improve functionalities future, leading innovative functional decrease environmental footprint simultaneously contribute sustainability sector.

In the upcoming years, world will face societal challenges arising, in particular, from impact of climate change and inefficient use natural resources, addition to an exponential growth population, which according United Nations (UN) estimations be 9.8 billion 2050. This increasing trend requires optimized management resources with value-added waste a significant reduction food loss waste. Moreover, recent pandemic situation, COVID-19, has contributed indisputably. Along agri-food supply chain, several amounts or by-products are generated. most cases, these biomass wastes cause serious environmental concerns high costs enterprises. The valorisation industry emerged as useful strategy produce certain compounds potential applications, namely food, health, pharmaceutical, cosmetic, fields. Therefore, this review, some crucial sustainable impacts on loss/wastes discussed identified, opportunities, trends innovations. Potential applications usages important found loss/waste highlighted, focus industry, pharmaceutical environment.

Fruit waste has emerged as a significant environmental issue in recent years, adding to the global burden. In Ghana, extensive use of plantains at various stages ripeness results substantial during each processing stage, leading disposal challenges. Interestingly, these wastes often hold considerable economic value and can be repurposed source valuable raw materials or products. Given broad range uses for pollution problems associated with their processing, finding new this organic become pressing necessity. This study investigated impact method extraction ripening on physicochemical characteristics pectin obtained from two different cultivars plantains, namely, Apem (M) Apantu (T), which are indigenous Ghana. Pectin samples were extracted (matured-green (G), half-ripe (H), full-ripe (R)) by utilization acidic (D) alkaline (L) methods. The analyses conducted included proximate composition moisture content determination, assessment mineral/elemental composition, solubility testing. Phytochemical investigations performed determine phytoconstituents present extracts. characterized determining equivalent weight, methoxyl anhydrouronic acid content, degree esterification. yields ranged 10.01% 46.55%. levels all pectins below 20%. All had swelling indexes between 37.5 ± 0.01% 185.71 0.02%. weight (EW) 1351.00 0.6 g/mol 10000.00 0.07 g/mol.
