Vacuum fractional distillation (VFD) is an efficient and environmentally friendly method for the separation and purification of thermally unstable and oxidizable bioactive compounds from essential oils through a virtually solvent-free process. This review highlights the importance of essential oil fractionation to meet the growing demands in the fragrance, cosmetic, food, and pharmaceutical industries. Fundamental principles and thermodynamics are summarized alongside VFD modeling, enabling prediction of phase behavior, column performance, hydrodynamics, and residence times, while reducing development time and scale-up risk. Published simulation and experimental studies are synthesized to define key influencing factors and practical operating windows for VFD performance. In addition, the review also identifies persistent data gaps, including non-standardized reporting practices, limited vacuum vapor-liquid equilibrium (VLE) data for key binary systems, and insufficient pilot-scale studies, which currently constrain reproducible research transfer and broader industrial implementation.

The present study focuses on the fabrication of magnetized tamarind kernel powder (MTKP) nanocomposites and graphene oxide-blended tamarind kernel powder (MTKP-GO) nanocomposites via co-precipitation method, and were employed for their application in the removal of Congo red dye from wastewater. Several physico-chemical techniques were investigated to analyse the surface morphology and structural identification of these nanocomposites. FE-SEM, XRD, and FTIR tests yielded distinctive findings, demonstrating the successful fabrication of magnetic TKP-GO with a sizable surface area and favourable magnetic response. Batch adsorption tests revealed a relatively greater adsorption potential for M TKP-GO (qmax= 236.795 mg/g) compared to M TKP (qmax =150.8045 mg/g). The pseudo-second-order model best fitted the data for adsorption kinetics with R2 valus of 0.9952 and 0.99604 for MTKP AND MTKP-GO respectively. Of all the isotherm models investigated, interestingly it was found that the Langmuir model best fit the adsorption data for M TKP, while the Freundlich isotherm model best explained the adsorption behaviour for M TKP-GO.

Nanoplastics, or NPs (< 100 nm), are a dynamically evolving class of contaminants whose environmental fate and biological effects are due to continuous physicochemical transformations. These particles very quickly take up different kinds of eco-coronas that contain humic substances, proteins, lipids, and microbial metabolites through one process of competitive adsorption and noncovalent interactions, changing their surface charge, colloidal stability, and mobility. Secondary NPs are formed under the influence of abiotic processes such as UV photolysis, thermo-oxidative ageing, and mechanical abrasion along with microbial enzymatic degradation that are rich in reactive functional groups of higher pollutant affinity. The synergistic toxicity, as well as amplified oxidative stress and enhanced membrane permeability, are mainly caused by NP-pollutant complexes that contain heavy metals, pharmaceuticals, PFAS and pesticides. NPs come into most biological systems by many different routes, where bio-coronas having noncovalent binding proteins and biolipids are the means by which cellular internalization, immune evasion, and tissue accumulation in liver, brain, placenta, and reproductive organs occur. Their deposition is a source of concern for trophic transfer and transgenerational effects. Adequate mitigation therefore requires remediation strategies, real-time nanoanalytics, spredictive modeling, and a mechanistic toxicology framework to safeguard environmental and human health.

The growing concerns over synthetic hair dyes necessitate exploring natural alternatives. Mangosteen (Garcinia mangostana L.) pericarp, an abundant agricultural waste rich in anthocyanins, presents a promising, underutilized source for natural hair coloration. This research evaluates mangosteen pericarp extract for developing a natural reddish hair dye, addressing common limitations in natural dye stability and color range. This study investigated the type of mordants (FeSO4, MgSO4, and Ca(OH)2) and the concentration in terms of color development, alongside optimizing extract concentration to achieve the highest reddish color intensity. Hair color was characterized using visual assessment and colorimetric analysis (L*, a*, b*, ΔE*). Results revealed that FeSO₄ applied at acidic pH produced the desired reddish hair color, with a 2 % (w/v) mordant concentration yielding the most intense hue. Furthermore, a 10 % (w/v) crude extract concentration produced the most significant color difference (ΔE*) when applied to bleached hair, indicating a darker reddish coloration. Crucially, color fastness tests, involving 30 cycles of washing and simulated sunlight exposure, demonstrated good persistence of the reddish color with 18 % color difference observed. Functional groups analysis using FTIR confirmed the presence of anthocyanin on the dyed hair, and the dyed hair's tensile strength increased from 35.38 (bleached hair) to 57.65 MPa. This work highlights the potential of mangosteen pericarp as a viable, eco-friendly hair colorant, contributing to agricultural waste valorization and offering a safer alternative in the cosmetics industry.

This study investigates the corrosion inhibition of AA6063 aluminium alloy in 1 M NaOH using calcinated bovine bone ash-derived hydroxyapatite (BBA-HAp). Electrochemical analyses revealed that at 0.6 g L⁻¹ inhibitor and 323 K, the inhibition efficiency (IE) reached 90.31 %, with the corrosion current density (Jcorr) decreasing from 2.04 × 10⁻⁴ A cm⁻² (control) to 2.01 × 10⁻⁵ A cm⁻². Adsorption behaviour transitioned from Freundlich-dominated (R² = 0.986 at 303 K) to Langmuir-dominated (R² = 0.998 at 323 K), indicating temperature-dependent monolayer formation, with ΔG°ads values between −16 and −25 kJ/mol confirming mixed adsorption mechanisms. Optical microscopy verified reduced surface degradation. Response Surface Methodology (RSM) optimization identified 0.541 g L⁻¹ inhibitor at 41.2 °C as optimal, yielding a corrosion rate (CR) of 0.19 mm/yr. These findings demonstrate that BBA-HAp provides effective, thermally stable, and sustainable corrosion protection for aluminium alloys in alkaline environments.

Achieving sustainable agricultural productivity and ensuring global food security are among the most pressing challenges faced in the 21st century. Currently, nanobiopesticides offer new possibilities for enhancing the efficacy of pest management strategies, which leads to improved crop production without compromising food and environmental safety. In this study, we have developed a nanobiopesticide using Delphinium cashmirianum-derived bio silver nanoparticles (DC-bAgNPs). To produce stable DC-bAgNPs, the effect of plant extract volume and silver salt concentration was studied and optimized. The analysis of the UV–visible spectrum revealed a distinct surface plasmon resonance (SPR) peak at 417 nm, which confirmed the photo fabrication of DC-bAgNPs. The morphology, elemental composition, particle size, stability, and surface functionality of the prepared DC-bAgNPs were studied using scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), dynamic light scattering (DLS), zeta potential, and Fourier transform infrared (FTIR) spectroscopy. The developed DC-bAgNPs based nanobiopesticide was then screened for antifungal activity against the fungal pathogen Cladobotryum dendroides, which causes cobweb disease in commercially cultivated mushrooms. The results demonstrated that the prepared DC-bAgNPs based nanobiopesticide showed good antifungal activity in the tested microbial strain. Thus, this study provides evidence that the developed nanobiopesticide can serve as an eco-friendly and non-toxic agent for treating fungal diseases in mushrooms, offering a sustainable solution to our agricultural system.

The sludge generated by the excipient manufacturing industry at the end of the effluent treatment process is usually disposed of in landfills, which can be detrimental to the environment. This study evaluated the potential to convert this pharmaceutical industry sludge (Especially a cellulosic sludge derived from excipient production unit) into biodiesel under different conditions during transesterification at 25 °C and 55 °C. Eight samples derived from four experimental conditions were tested (using Soxhlet extraction, ultrasonication at two different temperatures, and direct heating methods), yielding eight distinct properties, seven of which exhibit biodiesel characteristics as indicated by FT-IR and confirmed by GC-MS analysis. Out of the eight samples obtained, seven exhibited a minimum of 4 and a maximum of 46 ester groups at the retention time, while one sample did not produce any. The maximum composition was primarily methyl ester, followed by dimethyl ester. Across the four operating conditions, the Fatty Acid Methyl Ester (FAME) content ranged from 39.39 % to 67.4 %, with yields from 72 % to 81 %. The biodiesels produced were tested to ensure compliance with American Society for Testing and Materials (ASTM) standards, and their properties were thoroughly characterized. Two samples matched closely, except for their acid values (which were significantly higher) and flash points (which deviated considerably ≈, 7–18 %). The flame burning stability of the two samples was assessed as raw and blended with 2–10 % conventional diesel. The calorific values of those samples ranged from 3033.16 Cal/g to 8058.18 Cal/g. The study indicated that biodiesel produced from pharmaceutical industrial sludge waste exhibits good fuel characteristics; however, a significant drawback is the presence of sulfuric acid along with esters, which require further purification for potential application. Also, this investigation can divert waste from landfills and will reduce environmental impact.

This study evaluated the potential to convert this pharmaceutical industry sludge (<em>Especially a cellulosic sludge derived from excipient production unit</em>) into biodiesel under different conditions during transesterification at 25 °C and 55 °C. Eight samples derived from four experimental conditions were tested (<em>using Soxhlet extraction, ultrasonication at two different temperatures, and direct heating methods</em>), yielding eight distinct properties, seven of which exhibit biodiesel characteristics as indicated by FT-IR and confirmed by GC-MS analysis. Out of the eight samples obtained, seven exhibited a minimum of 4 and a maximum of 46 ester groups at the retention time, while one sample did not produce any. The maximum composition was primarily methyl ester, followed by dimethyl ester. Across the four operating conditions, the Fatty Acid Methyl Ester (FAME) content ranged from 39.39 % to 67.4 %, with yields from 72 % to 81 %. The biodiesels produced were tested to ensure compliance with American Society for Testing and Materials (ASTM) standards, and their properties were thoroughly characterized. Two samples matched closely, except for their acid values (which were significantly higher) and flash points (which deviated considerably ≈, 7–18 %). The flame burning stability of the two samples was assessed as raw and blended with 2–10 % conventional diesel. The calorific values of those samples ranged from 3033.16 Cal/g to 8058.18 Cal/g. The study indicated that biodiesel produced from pharmaceutical industrial sludge waste exhibits good fuel characteristics; however, a significant drawback is the presence of sulfuric acid along with esters, which require further purification for potential application. Also, this investigation can divert waste from landfills and will reduce environmental impact.</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"9 ","pages":"Article 100167"},"PeriodicalIF":0.0,"publicationDate":"2025-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145977067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Green catalysis has emerged as a cornerstone of sustainable organic synthesis, addressing global demands for environmentally responsible and cost-effective chemical production. While individual studies have demonstrated remarkable progress in catalyst efficiency and reusability, a systematic synthesis of recent innovations remains limited. This Systematic Review with Quantitative Synthesis consolidates evidence from 20 shortlisted studies (2020–2025) selected from an initial pool of 99, applying a structured review methodology to evaluate efficiency metrics (yield, turnover number, turnover frequency) alongside reusability indicators (recycling cycles, operational stability). The findings reveal that heterogeneous catalysts, particularly supported nanocatalysts and single-atom systems, consistently deliver superior yields and high turnover rates, while biocatalysts excel in selectivity and sustained reusability, often retaining > 90 % activity after multiple cycles. Organ catalysts and MOFs/POPs as heterogeneous catalysts contribute niche advantages in environmental benignity and scalability. Notably, innovative approaches such as biochar-modified g-C3N4, single-atom catalysts, and plasma-driven catalysis represent high-impact breakthroughs. The analysis also identifies trade-offs, where high efficiency does not always align with long-term recyclability. Beyond scientific insights, the study situates green catalysis within broader innovation and sustainability frameworks, highlighting implications for industrial translation and policy adoption. By integrating fragmented evidence into a coherent synthesis, this work advances both academic understanding and practical pathways for sustainable chemical innovation.
