This article aims to develop a method for regenerating and reusing carbon glass fibers extracted from unrecyclable scraps of plastics, printer parts, laminating coating. A comparison known methods fiber regeneration revealed the advantages thermal treatment: absence costs reagents complex equipment; better preservation composition; strength fibers. Based on results thermographic analysis wastes in nitrogen air, destruction temperatures their organic matrices were determined (200-460°С), use calcination instead pyrolysis was justified. The appearance surface quality regenerated are characterized by optical electron microscopy. It has been established that quantitative extraction pure waste crushed 1 cm is efficient at 700 °C 0.5 h 500 h, respectively. principle creating new composites with obtained based similarity composition binding materials (matrices) proposed. shown introduction wt% into slag blocks active pellets considerably increases compressive strength, but bending does not change due dispersed reinforcement. Possible improvement mechanical properties products requires reagent treatment or binder additives. Calculations show developed recycling composite can produce 2.3 tons/hour reinforced building good environment economy, excluding expenses landfill disposal reducing cost product replacing primary secondary one.

Forward osmosis (FO) is a low-energy treatment process driven by to induce the separation of water from dissolved solutes/foulants through membrane in hydraulic pressure absence while retaining all these materials on other side. All advantages make it an alternative reduce disadvantages traditional desalination processes. However, several critical fundamentals still require more attention for understanding them, most notably synthesis novel membranes that offer support layer with high flux and active permeability solute rejection both solutions at same time, draw solution which provides low flux, easy regeneration. This work reviews controlling FO performance such as role substrate advances modification utilizing nanomaterials. Then, aspects affect are further summarized, including types operating conditions. Finally, challenges associated process, concentration polarization (CP), fouling, reverse diffusion (RSD) were analyzed defining their causes how mitigate them. Moreover, factors affecting energy consumption system discussed compared (RO). review will provide in-depth details about technology, issues faces, potential those help scientific researcher facilitate full technology.

Membrane distillation (MD) has emerged as a highly promising method for the treatment of intricate and heavily contaminated water sources, such those containing oily wastewater. The present study endeavors to advance field by designing evaluating novel nanocomposite membrane comprised polyvinylidene fluoride (PVDF) Bentonite (BNT) application in vacuum (VMD) processes targeted at treating A series five flat sheet membranes were meticulously fabricated, incorporating varying quantities bentonite (ranging from 0 0.8 g). Systematic characterizations undertaken comprehensively elucidate influence BNT incorporation on structural functional attributes developed membranes. These encompassed an array analytical techniques, including Fourier Transform Infrared Spectroscopy (FTIR), atomic Force Microscopy (AFM), X-Ray diffraction (XRD), emission scanning electron microscopy (FESEM), contact angle measurements (CA), well assessments thickness, porosity, pore size, size distribution. findings distinctly showcased successful integration within PVDF matrix, which correspondingly led discernable augmentations surface roughness, hydrophobicity, porosity. Employing consistent operational conditions involving feed temperature 50°C, pressure 30 kPa, NaCl solution with concentration 14.75 g/L, VMD experiments systematically conducted. empirical outcomes revealed that notably conferred substantial enhancements upon membrane's performance. pinnacle achievement was evidenced flux rate 34 L/m2.h remarkable rejection 99.92%, result achieved highest content additives.

It is estimated that Reverse Osmosis (RO) desalination will produce, by 2025, more than 2,000,000 end-of-life membranes annually worldwide. This review examines the implementation of circular economy principles in RO technology through a comprehensive analysis membrane life cycle (manufacturing, usage, and management). Future design should incorporate biobased composition (biopolymers, recycled materials, green solvents), improve durability (fouling chlorine resistance), facilitate recyclability modules. Moreover, proper maintenance at usage phase, attained feed pre-treatment, early fouling detection, cleaning methods can help extend service time elements. Currently, are dumped landfills, which contrary to waste hierarchy. analyses up now developed alternative valorisation routes membranes, including reuse, direct indirect recycling, energy recovery, placing special focus on emerging recycling strategies. Lastly, Life Cycle Assessment presented as holistic methodology evaluate environmental economic burdens According European Commission’s objectives set Green Deal, future perspectives indicate strategies keep gaining increasing interest upcoming years.
