The growing reliance on diverse analytical techniques and chemical solvents has raised significant environmental concerns due to their potential ecological impact. Dapagliflozin, a novel and effective SGLT2 inhibitor, has gained attention for its strong therapeutic benefits in managing type 2 diabetes mellitus, particularly due to its insulin-independent action and added cardiovascular protection. This study consolidates and critically evaluates the diverse analytical techniques established for the quantification of Dapagliflozin across distinct matrices, including its fixed-dose combinations. The methodologies encompass a broad spectrum of instrumental techniques, including UV spectrophotometry, high-performance liquid chromatography, high-performance thin-layer chromatography, ultra-performance liquid chromatography, and liquid chromatography–mass spectrometry. A special emphasis is placed on the types of solvents employed in these methods and the associated solvent waste, which is evaluated to determine the environmental sustainability of each approach. The environmental sustainability of these approaches was evaluated using established tools such as the Analytical Eco-Scale, Green Analytical Procedure Index, and AGREE metrics. This review aims to support the advancement of greener analytical strategies that ensure both the reliable quantification of Dapagliflozin and a reduced ecological footprint.

A biophotovoltaic technology (bio cathode MDC) on a new platform, featuring five cells instead of the customary three, is used to investigate MDC’s potential for treating specific minerals in real saline groundwater. The study examined how salt levels and nutrient concentrations affected the system’s performance in three concentration scenarios with a continuous operating mode. The experimental findings included power density with 1000 Ω of external resistance present, desalination efficiency, heavy-metal (copper) removal efficiency, hard-metal (magnesium and calcium) removal efficiency, percentages of chemical oxygen demand (COD) removed, percentages of nitrate and phosphate removed, and algae cultivation performance. The highest power densities were 49.8 mW/m² and 205.44 mW/m³, calculated based on the anode surface area and the anolyte volume, respectively, with a maximum total dissolved solids (TDS) removal of 55%. The highest ion removal percentages were 78.36%, 72.57%, and 96.9% for magnesium, calcium, and copper, respectively. The COD removal rate was 90.6%, with the highest clearances of 93.1% for phosphate and 84.55% for nitrate. The algae had a dry weight of 16 g/L. With this expanded platform, which provides more capacity to handle larger volumes of wastewater and to generate electricity, the MDC system efficiently removes minerals from saline water. It simultaneously enables the desalination of more saline water and the treatment of other effluents by using light to cultivate algae. Biophotovoltaic is a promising treatment method that could be applied to various industrial effluents.

新平台上的生物光伏技术（生物阴极MDC）具有五个电池而不是通常的三个电池，用于研究MDC处理实际含盐地下水中特定矿物质的潜力。该研究考察了在连续运行模式下，盐水平和营养浓度在三种浓度情况下对系统性能的影响。实验结果包括：外阻为1000 Ω时的功率密度、海水淡化效率、重金属（铜）去除率、硬金属（镁和钙）去除率、化学需氧量（COD）去除率、硝酸盐和磷酸盐去除率以及藻类培养性能。根据阳极表面积和阳极液体积计算，最高功率密度分别为49.8 mW/m²和205.44 mW/m³，最大总溶解固体（TDS）去除率为55%。对镁、钙和铜的离子去除率分别为78.36%、72.57%和96.9%。COD去除率为90.6%，其中磷酸盐去除率最高，为93.1%，硝酸盐去除率最高，为84.55%。藻类干重为16 g/L。有了这个扩展的平台，它提供了更多的能力来处理更大量的废水和发电，MDC系统有效地从盐水中去除矿物质。它同时使更多的咸水脱盐和处理其他污水利用光培养藻类。生物光伏是一种很有前途的处理方法，可应用于各种工业废水。

With the global push toward decarbonization and sustainable energy solutions, the demand for clean hydrogen production using electrolysis has surged in recent years. The objective of this experimental study is to investigate the effect of applied voltage on the performance of Proton Exchange Membrane (PEM) electrolyser at different operating temperatures. The experimental tests are conducted using PEM electrolyzer equipped with a Nafion 115 membrane electrode assembly. The PEM electrolyser begins producing measurable hydrogen and oxygen only above a threshold voltage of 1.6 V. The highest hydrogen production observed was 13.88 ml/min at 2.54 V and 1.7 A. The findings from this study have significant implications for optimizing the performance of PEM electrolysers in clean hydrogen production.

The accelerating global demand for hydrogen is pushing for renewable and waste derived hydrogen production processes, where, date palm waste (DPW) has been identified as an available and unexploited agricultural residue that has the potential to be a sustainable source of hydrogen. The current work focuses on developing and evaluating four different process configurations in terms of energy, environment and economics for producing hydrogen from DPW using Aspen Plus® simulation tool. Case 1 represents the standalone DPW gasification with CO₂ capture via methanol absorption, Case 2 represents the DPW gasification with CaO-based chemical looping for CO₂ capture, Case 3 represents the DPW gasification integrated with steam methane reforming (SMR) and methanol-based CO₂ capture, and Case 4 represents the DPW gasification integrated with SMR and CaO-based CO₂ capture. Each case was evaluated in terms of syngas composition, hydrogen production, lower heating value, CO₂ captured, utility demand, process efficiency, and H₂ production cost. Hydrogen production ranged from 974.55 t/year (Case 1) and 988.83 t/year (Case 2) to 2032.32 t/year (Case 3) and 2048.61 t/year (Case 4). CO₂ capture was also more effective in Case 4 (16,929.49 t/year) compared to Case 1 (7676.30 t/year). Process efficiency improved from 33 % in Case 1 to 47 % in Case 2, and from 32 % in Case 3 to further to 55 % in Case 4. Economically, Case 1 offered the highest hydrogen production cost ($5.03/kg) followed by Case 2 ($4.77/kg), while Case 3 and Case 4 achieved significantly lower production costs of $2.89/kg and $2.69/kg, respectively.

全球对氢的需求不断加速，推动了可再生和废物衍生制氢工艺的发展，其中，枣椰树废料（DPW）已被确定为一种可用且未开发的农业残留物，有可能成为可持续的氢来源。目前的工作重点是利用Aspen Plus®模拟工具，从能源、环境和经济角度开发和评估四种不同的DPW制氢工艺配置。案例1为采用甲醇吸附法捕集二氧化碳的单机DPW气化，案例2为采用cao基化学环法捕集二氧化碳的DPW气化，案例3为采用蒸汽甲烷重整（SMR）和甲醇基捕集二氧化碳的单机DPW气化，案例4为采用SMR和cao基捕集二氧化碳的单机DPW气化。每种情况都从合成气组成、制氢量、较低的热值、二氧化碳捕获量、公用事业需求、工艺效率和制氢成本等方面进行了评估。氢气产量从974.55 t/年（案例1）和988.83 t/年（案例2）到2032.32 t/年（案例3）和2048.61 t/年（案例4）不等。与案例1（7676.30吨/年）相比，案例4（16,929.49吨/年）的CO₂捕获效果也更有效。流程效率从案例1的33%提高到案例2的47%，从案例3的32%进一步提高到案例4的55%。从经济角度来看，Case 1的制氢成本最高（5.03美元/kg），其次是Case 2(4.77美元/kg)，而Case 3和Case 4的生产成本分别显著降低，为2.89美元/kg和2.69美元/kg。

The increasing concern regarding Carbon dioxide (CO₂) emissions from fuel combustion and industrial exhaust underscores the necessity for efficient CO₂ capture techniques to attain the net-zero ambition for hard-to-abate industries. One of the sustainable methods for reducing CO₂ emissions from such industries remains absorption-based post-combustion CO₂ capture (PCC). In this process, amine solvents are used in conjunction with packed columns and Rotating Packed Beds (RPBs). The RPB absorber is a powerful alternative to conventional packed columns due to its compact design and enhanced mass transfer efficiency. Increasing the effectiveness of CO₂ removal necessitates a comprehensive solvent development. The present study focuses on a blended amine solvent comprising piperazine (PZ) and methyldiethanolamine (MDEA) to investigate CO₂ absorption. The study incorporates both mathematical modelling and machine learning (ML) to predict CO₂ absorption efficiency. Additionally, this study aims to optimize the energy requirements. Experimental data from the literature is used to assess the prediction accuracy of mathematical models and two ML techniques, namely Deep Kernel Learning with Gaussian Process Regression (DKL-GP) and Regularized Extreme Learning Machine (RELM). Statistical analysis is employed to enhance the ML models. Predictive performance is observed to be suitable for both models, although the DKL-GP accuracy is greater, with R², MAE, and RMSE values of 0.99, 0.006, and 0.006, respectively. Furthermore, the prediction results from the mathematical model and ML models are also in close agreement with each other. The results highlight the importance of integrating ML with conventional modelling to inform future design of increased carbon capture processes.

对燃料燃烧和工业废气产生的二氧化碳（CO₂）排放的日益关注强调了对难以减排的工业实现净零目标的有效CO₂捕获技术的必要性。减少这些行业二氧化碳排放的可持续方法之一仍然是基于吸收的燃烧后二氧化碳捕获（PCC）。在此过程中，胺溶剂与填充柱和旋转填充床（rpb）一起使用。RPB吸收塔是一个强大的替代传统填料柱，由于其紧凑的设计和提高传质效率。提高CO₂去除效果需要全面的溶剂开发。本文研究了哌嗪（PZ）和甲基二乙醇胺（MDEA）的混合胺溶剂对CO₂的吸收。该研究结合了数学建模和机器学习（ML）来预测CO₂吸收效率。此外，本研究旨在优化能量需求。文献中的实验数据用于评估数学模型和两种机器学习技术的预测精度，即深度核学习与高斯过程回归（DKL-GP）和正则化极限学习机（RELM）。采用统计分析方法对ML模型进行增强。虽然DKL-GP的准确率更高，R2、MAE和RMSE分别为0.99、0.006和0.006，但两种模型的预测性能都是合适的。此外，数学模型和机器学习模型的预测结果也非常吻合。结果强调了将机器学习与传统建模相结合的重要性，以便为未来设计增加的碳捕获过程提供信息。

MXenes, a class of two-dimensional transition metal carbides and nitrides, have emerged as versatile and high-performance materials for carbon capture and utilization (CCU) technologies. Their large surface area, adjustable surface terminations, and excellent electrical conductivity make them highly suitable for applications ranging from CO₂ adsorption and membrane separation to catalytic conversion. This review critically examines recent advances in MXene-based systems for CO₂ management, focusing on their roles in physical and chemical adsorption and integration into mixed matrix membranes (MMMs). Notable performance metrics include adsorption capacities ranging from 4.2 to 6.8 mmol/g, Faradaic efficiencies up to 85 %, and photoconversion rates exceeding 400 µmol/g·h. The review also discusses the engineering challenges related to scalability, oxidative stability, and compatibility with existing industrial infrastructures. Furthermore, MXenes are highlighted as key enablers in the transition towards a circular carbon economy, offering multifunctionality across various CCU stages. Despite hurdles related to synthesis and policy integration, MXenes present strong potential as next-generation materials for sustainable carbon-neutral technologies. The review concludes by outlining future directions, including green synthesis strategies, composite material engineering, techno-economic assessments, and the development of regulatory frameworks to support real-world deployment.

The rapid growth of the global population has significantly increased the production of bio-wastes, which are rich in essential plant nutrients such as phosphorus (P), nitrogen (N), and potassium (K). These nutrients can help mitigate the negative effects associated with synthetic fertilizers in agriculture. By repurposing bio-waste from sources like agricultural residues, animal manure, and sewage sludge, it is possible to recover valuable nutrients and create products that support a circular economy. This process of waste valorisation transforms waste into valuable products that improve soil health and promote plant growth. For example, vermicomposting of municipal solid waste using microbial consortia such as Nitrosomonas, Azotobacter, and Nitrobacter has been shown to significantly increase nutrient recovery, with reported improvements in nutrients to as high as 2.1–2.6% N, 1.5–1.7% P, and 1.4–1.6% K in vermicompost—considerably higher than those found in traditional animal manures. Using bio-based fertilizers derived from these wastes can boost agricultural productivity while reducing the environmental impact of non-organic fertilizers. Further investigation is required to evaluate the practical applications of bio-based fertilizers in the field. This need is underscored by insights from previous studies referenced in this review, which aim to uphold agricultural sustainability and productivity. This review highlights the potential of cutting-edge technology and microbial activity in developing bio-based fertilizers, advancing waste minimization, and optimizing resource use within a circular economy. Microbial and biological systems offer sustainable and efficient strategies for converting various bio-wastes into bio-based fertilizers, thereby supporting a circular economy in agriculture.

全球人口的快速增长大大增加了生物废物的产生，这些废物富含必需的植物营养物质，如磷(P)、氮(N)和钾(K)。这些营养物质有助于减轻与农业合成肥料有关的负面影响。通过重新利用农业残留物、动物粪便和污水污泥等来源的生物废物，有可能回收有价值的营养物质，并创造支持循环经济的产品。这一废物增值过程将废物转化为有价值的产品，改善土壤健康并促进植物生长。例如，利用亚硝化单胞菌、固氮杆菌和硝化杆菌等微生物群落对城市固体废物进行蚯蚓堆肥，已被证明可显著提高营养物质的回收率，据报道，蚯蚓堆肥中营养物质的氮含量高达2.1-2.6%，磷含量为1.5-1.7%，钾含量为1.4-1.6%，远远高于传统动物粪便。使用从这些废物中提取的生物基肥料可以提高农业生产力，同时减少非有机肥料对环境的影响。评价生物基肥料在田间的实际应用还需要进一步的研究。本综述中引用的以往研究的见解强调了这一需求，这些研究旨在维护农业的可持续性和生产力。这篇综述强调了尖端技术和微生物活性在开发生物基肥料、推进废物最小化和优化循环经济中的资源利用方面的潜力。微生物和生物系统为将各种生物废物转化为生物基肥料提供了可持续和有效的战略，从而支持农业循环经济。

By repurposing bio-waste from sources like agricultural residues, animal manure, and sewage sludge, it is possible to recover valuable nutrients and create products that support a circular economy. This process of waste valorisation transforms waste into valuable products that improve soil health and promote plant growth. For example, vermicomposting of municipal solid waste using microbial consortia such as Nitrosomonas, Azotobacter, and Nitrobacter has been shown to significantly increase nutrient recovery, with reported improvements in nutrients to as high as 2.1–2.6% N, 1.5–1.7% P, and 1.4–1.6% K in vermicompost—considerably higher than those found in traditional animal manures.

Microbial Fuel Cells (MFCs) are a bioelectrochemical technology that is associated with innovation, as they utilize the metabolism of microorganisms to break down organic waste into electricity, offering two key benefits: clean energy and wastewater treatment (dual benefits). This review presents an overview of recent innovations in MFC design, materials, and microbial engineering that aim to address critical issues, including low power density, biofouling, and scalability. The power densities have been considerably enhanced to 600 mW/m², and COD removal efficiencies and Coulombic efficiency have increased to 92% and 65%, respectively, over the past five years. The most prominent trends in this development are the appearance of nanostructured electrodes, conductive polymers, well-designed microbial consortia, and innovative membrane materials. Artificial intelligence and hybrid renewables have created a new opportunity to improve performance and minimize cost. Nevertheless, commercial application is still hindered by the high cost of the material and its long-term stability issues. This review explores the potential of MFCs in the context of decentralised energy systems and the circular economy, critically appraising the existing research on the topic. By combining waste management with clean energy production, MFCs offer a promising approach to achieving environmental sustainability and energy resilience.

微生物燃料电池（MFCs）是一种与创新相关的生物电化学技术，因为它们利用微生物的代谢将有机废物分解为电能，提供两个关键好处：清洁能源和废水处理（双重好处）。本文概述了MFC设计、材料和微生物工程方面的最新创新，旨在解决包括低功率密度、生物污垢和可扩展性在内的关键问题。在过去的五年中，功率密度大大提高到600 mW/m²，COD去除效率和库仑效率分别提高到92%和65%。这一发展中最突出的趋势是纳米结构电极、导电聚合物、精心设计的微生物群落和创新膜材料的出现。人工智能和混合可再生能源为提高性能和降低成本创造了新的机会。然而，由于材料的高成本及其长期稳定性问题，商业应用仍然受到阻碍。本综述探讨了分散能源系统和循环经济背景下mfc的潜力，批判性地评估了关于该主题的现有研究。通过将废物管理与清洁能源生产相结合，mfc为实现环境可持续性和能源弹性提供了一种有希望的方法。

An industrially relevant method for obtaining hydrogen from hydrocarbons without emitting carbon into the atmosphere involves ethanol-steam reforming followed by carbon capture. Herein, we present a detailed conceptual process using ethanol-stream reforming to produce blue hydrogen, integrated with a carbon capture plant, followed by a techno-economic analysis. In the first step, the Aspen plus-based simulation of ethanol-stream reforming reactions is performed to optimize the reforming reactor geometrical parameters for a 10 t/day of hydrogen production. Afterward, the carbon capture system was designed with a standalone absorber and stripper, which were subsequently integrated for solvent makeup calculation. Considering the target value of hydrogen production, the optimized reactor diameter and length were found to be 0.18 and 2 m, respectively, corresponding to reactant flow (200 t/day) and heat duty (3.14 MW) at optimal circumstances. Absorber and stripper packing heights of 12.2 m and 5 m, respectively, with column diameters of 1.22 m and 2.60 m are required to extract 95 % CO₂ from the reformed product stream. The techno-economic analysis indicates that the cost of producing one kilogram of H₂ is $3.5. The computed internal rate of return is 16.6 %, the discounted payback period is 6 years, and the net present value is $13 million.

从碳氢化合物中获得氢而不向大气中排放碳的工业相关方法包括随后的碳捕获的乙醇-蒸汽重整。在此，我们提出了一个详细的概念过程，使用乙醇流重整生产蓝色氢，与碳捕获装置相结合，然后进行技术经济分析。在第一步中，进行了基于Aspen plus的乙醇流重整反应模拟，以优化重整反应器的几何参数，以实现10吨/天的氢气生产。随后，碳捕获系统设计了一个独立的吸收塔和汽提塔，随后集成溶剂组成计算。考虑产氢目标值，优化后反应器直径为0.18 m，反应器长度为2 m，对应最优条件下反应物流量为200 t/d，热负荷为3.14 MW。吸收塔和汽提塔填料高度分别为12.2 m和5 m，塔径分别为1.22 m和2.60 m，可从重整产物流中提取95%的CO2。技术经济分析表明，生产一公斤氢气的成本为3.5美元。计算的内部收益率为16.6%，贴现回收期为6年，净现值为1300万美元。

The catalytic conversion of carbon dioxide (CO₂) into valuable sustainable aviation fuel (SAF) is a " two-birds in one-stone" strategy for addressing the environmental challenges and fulfilling the present fuel demands in the aviation sector. In this present review, recent advances in various catalytic pathways, including mechanistic insights, catalyst architecture for conversion of CO₂ to SAF are systematically explored. For conversion of CO₂ into SAF with maximum conversion and high selectivity, the determining factors are reaction pathway, design of catalyst, their composition etc. Generally, production of SAF from CO₂ takes place via two pathways: indirect and direct path. Here we have investigated recent progress in various reaction pathways, such as Reverse Water Gas Shift (RWGS) and Fischer-Tropsch synthesis (FTS) reaction, alcohol to jet fuel (AtJ) process, direct CO₂ conversion etc. The research underlines the necessity of improved catalytic methods in achieving excellent selectivity and robustness during commercial application, particularly important for CO₂ to SAF synthesis. Finally, the goal of this study is to present an in-depth evaluation of the present status of SAF investigation and commercialization for future prospectives.
