Water resources are under pressure worldwide, resulting in scarcity and deterioration of freshwater quality. According to European directives, we could reduce the on water urban areas by increasing reuse treated wastewater, reducing impact bodies, promoting recycling through multiple uses wastewater. Besides need address supply challenges, wastewater treatment systems show environmental stewardship innovative practices. Using reclaimed for agricultural irrigation is gaining interest because...
This work presents an updated overview of waste lubricant oil (WLO) management practices in Europe to promote a circular economy. The characteristics virgin and oil, their hazardous properties the impacts improper disposal are addressed. Current treatment routes regeneration technologies adopted presented. An life cycle assessment (LCA) WLO strategies summarized. Finally, future developments concerns about process discussed. current objectives European Union toward economy represent...
The optimization of extraction by using solvents phenolic compounds (TPh) grape pomace (GP) based on a central composite design was investigated. GP characterized, and preliminary assays were conducted with five different (water, ethanol, acetone, methanol, butanol) the aqueous mixtures thereof. Ethanol acetone revealed to be best for TPh extraction. main parameters (temperature-T, time-t, solvent concentration, liquid-solid ratio-L/S) optimized design. conditions ethanol (T = 60 °C, t 1.5...
Abstract In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Ascenza Agro S.A. submitted a request to competent national authority in France modify existing maximum residue level (MRL) for active substance metalaxyl‐M honey. The data support were found be sufficient derive MRL proposal Adequate analytical methods enforcement are available control residues honey matrix at validated limit quantification (LOQ) 0.01 mg/kg. Based on risk assessment results, EFSA concluded...
In this work, activated carbon nanoparticles (AC) at concentrations ranging from 0 to 1 wt% were used prepare polyethersulfone nanofiltration membranes. The effectiveness of these membranes in separating lignin black liquor (BL) was evaluated under various operating conditions. addition AC improved all desirable properties. For instance, water permeability increased by 57.50 % with the and surface hydrophilicity reducing contact angle 66.8° 55.2° for 0.5 AC-based compared simple polymeric BL...
This work focuses on the precipitation of lignin from kraft black liquor (BL) along with its valorization into nanoparticles (LNP). Two organic acids namely, acetic acid, and lactic acid were used for as an alternative to sulfuric acid. An optimization study was carried out determine effect three key variables, namely type, temperature, pH, isolation yield purity lignin. The showed that all factors primarily influenced yield, while precipitated varied only around 1 % between minimum maximum...
The Kraft pulp industry is a relevant industrial sector in many countries with considerable social, economic, and environmental impact. Thus, sustainability the adequate framework to address this activity sector. This work presents review of literature, particular focus on bleaching area its relevance reducing water use. reports most prominent paper companies were analyzed, considering their specific utilization targets they have outlined. industrially applied sequences also addressed stages...
Phosphorus (P) is a critical element for life, and wastewater treatment systems can be strategic points its recovery, thereby avoiding eutrophication pollution in nature. The aim of this research was to investigate P recovery via struvite, namely terms the influence operating parameters, coexisting interfering ions, seeding. This paper focuses on synthetic solutions, although an assessment performed wastewater. results indicated that, solution, minimum concentration struvite precipitation...
Potato peel (PP) is generated in high quantities and commonly wasted by potato processing industries. However, PP can be valorized through different routes while recovering value-added compounds energy. There an urgent need to evolve toward appropriate circular management approach for human health ecosystem protection. Biorefinery maximizes the valorization of residues closing carbon loop. has mainly been used animal feed or biogas production anaerobic digestion, but its value may increase...
