Over the past few decades, polymers have been extensively employed in various sectors attributed to their exceptional properties. The presence of vast quantities non-degradable environment, addition industrial effluents, has become one serious global issues. chemically sourced polymers/composites are potentially hazardous biosphere due slow degradation mechanism. Currently, there is a growing interest geopolymers as upcoming competitors over synthetic polymers, efficaciously extracted from natural resources. These environment-substitutes exceptionally beneficial environmental applications, particularly wastewater treatment processes. Therefore, this review article comprehensively discusses synthesis geopolymers/composites different precursors. most prevalent analytical methods used characterize discussed get insights into physico-chemical characteristics. Moreover, potential technologies using geopolymers-based materials (i.e., adsorption, photocatalytic degradation, membrane filtration, and solidification/stabilization pathway) briefly highlight developments engineering Furthermore, circular economy model framework proposes approaches applying principles management sector. Overall, can be considered promising materials, making strides cutting down dependency on remediation.

The stress of pharmaceutical and personal care products (PPCPs) discharging to water bodies the environment due increased industrialization has reduced availability clean water. This poses a potential health hazard animals human life because contamination is great issue climate, plants, humans, aquatic habitats. Pharmaceutical compounds are quantified in concentrations ranging from ng/Lto μg/L environments worldwide. According (Alsubih et al., 2022), carbamazepine, sulfamethoxazole, Lutvastatin, ciprofloxacin, lorazepam were 616–906 ng/L, 16,532–21635 694–2068 734–1178 2742–3775 ng/L respectively. Protecting preserving our must be well-driven by all sectors sustain development. Various methods have been utilized eliminate emerging pollutants, such as adsorption biological advanced oxidation processes. These their benefits drawbacks removal pharmaceuticals. Successful wastewater treatment can save bodies; integrating green initiatives into main purposes actor firms, combined with continually periodic awareness current implications environmental/water pollution, will play major role conservation. article reviews key publications on adsorption, biological, processes used remove environment. It also sheds light capability methods, efficacy concentration removal. A research gap identified for researchers explore order problem associated wastes. Therefore, future study should focus combining an excellent way products, even at low concentrations. Biological ideal circumstances microbial that enable simultaneous effects diverse efficiency.

This study investigated the successful synthesis of functionalized algal biochar-clay composite (FBKC). Subsequently, sorption performance FBKC towards norfloxacin (NFX) antibiotic and crystal violet dye (CVD) from water was extensively assessed in both batch continuous flow systems. A series characterization techniques were carried out for utilized precursors, indicating that surface area increased thirty-fold with a well-developed pore structure compared to original precursors. demonstrated maximum capacity 192.80 281.24 mg/g NFX CVD, respectively. The suited fitting experimental data Freundlich Clark models suggested multi-layer NFX/CVD molecules. mechanistic studies onto unveiled multiple mechanisms, including π-π interaction, hydrogen bonding, electrostatic attraction, surface/pore filling effect. estimated cost 5.72 €/kg superior makes an efficient low-cost sorbent emergent pollutants.

Industrial residues like Basic Oxygen Furnace (BOF) slag and Iron Ore Tailings (IOT) in the construction sector conserves natural resources by reducing carbon emissions enhancing sustainability. However, it is crucial to establish significant research findings build confidence among end users stakeholders facilitate adoption of same for practical applications. This study aims investigate feasibility using BOF Fly ash (FA) as primary precursors development steel fibre (SF) reinforced Engineered Geopolymer Composites (EGC) with IOT replacing M-Sand fine aggregate. Trial mixes (600 No.s) were conducted synthesize EGC slag, FA, IOT, SF. Compressive strength was measured found significantly improve EGC, following SF levels. Six optimized identified subjected water absorption, flexure, impact resistance leaching toxicity heavy metals. The mix comprising 40% BOF, 1.5% 45% showed highest characteristics viz., 41.8 MPa, 5.78 MPa 313.92 Nm correspondingly compression, flexure impact. obtained results have implications sustainable involving FA viable precursors, alongside a partial substitute
