This review offers a comprehensive and structured analysis of recent advancements in the synthesis, modification, and application of activated carbon, with an emphasis on sustainable development. The study critically evaluates fabrication techniques—including physical activation, chemical activation, hydrothermal carbonization, and microwave-assisted methods—using renewable precursors such as agricultural residues, industrial by-products, and natural biomass. Comparative insights into physical forms (powdered, granular, pellet, and membrane) and their influence on adsorption efficiency are also presented. The paper explores various chemical, physical, and microwave-assisted modification techniques aimed at enhancing surface area, porosity, and functional selectivity. It highlights the role of pore size distribution (micro-, meso-, and macropores) in adsorption dynamics and explains how surface functionalization, metal doping, and nitrogen/sulfur treatments tailor activated carbon for specific contaminants. Applications span multiple domains, including the removal of dyes, heavy metals, volatile organic compounds (VOCs), pharmaceuticals, and greenhouse gases like CO₂. In addition to mapping out practical applications, the study identifies key benefits such as cost-effectiveness, resource circularity, and regenerability. It also acknowledges prevailing challenges—including environmental concerns associated with chemical activation, material variability, and scale-up limitations. The manuscript integrates emerging trends in green activation, hybrid composites, nanotechnology, and predictive modeling, providing a forward-looking roadmap for researchers and industry practitioners. By aligning technological innovation with environmental sustainability, this work establishes activated carbon as a cornerstone material for future eco-engineered solutions.</p>","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146139734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sanitary waste, co-gasified with CO₂, produces hydrogen-rich syngas, offering a novel route for both waste valorization and partial diesel displacement. The engine was operated under varying load conditions using different diesel-syngas injection strategies (DS2–DS10), with syngas port-injected and diesel directly injected. A combined energy and exergy analysis was performed to evaluate combustion behavior, emission characteristics, entropy generation, and the sustainability index. The results revealed that the DS2 blend (2 ms syngas injection) delivered the most balanced performance, achieving only a 4.1% reduction in exergy efficiency compared to diesel while limiting exergy destruction and entropy generation. Higher syngas fractions such as DS10 degraded performance, leading to an 18.45% drop in exergy efficiency and a 36.26% increase in entropy generation. Compared to diesel, DS2 showed minor losses in BTE (4.68%) and exhaust energy (3.72%) but enabled a net improvement in environmental sustainability metrics. The novelty of this work lies in demonstrating the viability of sanitary-waste syngas as a co-fuel in RCCI mode, supported by integrated thermodynamic and sustainability assessments, extending beyond conventional biomass syngas applications by addressing the energy-exergy trade-offs of hydrogen-rich waste-derived fuels.</p>","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146136873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the commonly used superhydrophilic separation membranes suffer from a complex hydrophilic modification process, high cost, and low efficiency. Herein, a cost-effective superhydrophilic aerogel membrane was presented via phase transfer and low-temperature plasma strategy using waste polyethylene as a building block. This plasma strategy involves directly and swiftly introducing oxygen functional groups with high surface energy onto the membrane surface, avoiding classical and sophisticated wet chemistry such as graft polymerization or physical modification. Such a direct plasma strategy renders the intrinsically hydrophobic polyethylene-based aerogel membrane stable and robust superhydrophilicity in harsh environments and excellent underwater anti-oil adhesion properties, thus achieving excellent gravity-driven oil-in-water emulsions separation with high flux (1940 L m⁻² h⁻¹) and high separation efficiency (98.9%). Additionally, this directly hydrophilized aerogel membrane presents favorable reusability, thereby maintaining satisfactory separation flux and efficiency even after 10 cycles of separation. Overall, this work provides a general and efficient avenue to surface engineer polyethylene-based aerogel membrane for rapid separation of oil-in-water emulsion wastewater.</p>","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146136175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study adopted factorial experiments and response surface design to verify the most critical factors and determine the optimal conditions in eggshell reduction operations. Also, isothermal and kinetic adsorption models were used to demonstrate the metal adsorptive characteristics of the non-reduced and optimally reduced eggshells that adsorbed silver, copper, and chromium in water. Analysis-wise, metals in water were treated by aqua regia digestion and analyzed through inductively coupled plasma atomic emission spectroscopy (ICP-AES). Results revealed that thioglycol (i.e., 2-mercaptoethanol) and reaction time were the two most critical eggshell-modifying factors. Results of the response surface experiments indicated that the optimal eggshell reduction conditions were at the initial reductant concentration and reaction time equal to 9.75 M and 1.9 h, respectively. As for the isothermal metal adsorption using the modified eggshells, it fit the Langmuir model the best with the maximum adsorption capacities (<i>q</i>_m) of silver, copper, and chromium equal to 1.35, 2.09, and 2.39 mmole/g-ES, respectively. Data revealed that the reduced eggshells could completely adsorb silver, copper, and chromium within five hours and adsorbed around 6 and 2.6 times more copper and silver than the unreduced eggshells. These results demonstrate the much better uses of the reduced eggshells than plain eggshells for water metal purification.</p>","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146136402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike previous research, this research uniquely demonstrates that optimization of the in-built compression ratio in diesel-CHP systems can alone result in significant efficiency, economic, and environmental improvements. This novel 4E analysis and optimization approach opens up a new design pathway via quantification of multi-objective trade-offs of compression ratio modulation, thereby advancing CHP system design beyond peripheral retrofits. It has been demonstrated that raising the compression ratio (14:25) elevates engine power output by 44% and recoverable heat, to as much as 89.5% CHP efficiency. These advantages are realized, however, at severe costs: 6.8% more exergy destruction and 10.3% less carbon emission savings (CDER). To mitigate these trade-offs, a novel multi-objective genetic algorithm framework was developed with normalized objectives. Optimization returns cr = 20.11 as the Pareto-optimal solution, trading off 89.13% CHP efficiency, 0.2469 $/kWh energy cost, moderated exergy destruction (44.7 kJ/kg), and sustainable CDER (0.2389).
