However, the role of water films in this process remains poorly quantified. This review evaluates current understanding of water-film properties and the potential influence on salt precipitation and CO₂ injectivity. Water-film behavior is controlled by coupled surface, pore-scale, fluid, and injection conditions and therefore cannot be represented by a single universal film thickness. Connected water films may sustain brine and dissolved ion transport towards drying regions, influencing supersaturation, salt growth, and spatial distribution. However, their relationship with injectivity is indirect and multiscale, as permeability impairment depends strongly on the amount, morphology, and location of precipitated salts, while other geochemical, geomechanical, and operational processes may concurrently alter injectivity. Available studies largely infer water-film behavior indirectly, with limited direct quantitative measurements under reservoir conditions. This review therefore proposes a hybrid multiscale framework integrating nanoscale characterization, pore-scale visualization, core-scale experiments, and reservoir modeling, with explicit consideration of uncertainty during upscaling.</div></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"13 ","pages":"Article 101075"},"PeriodicalIF":6.4,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149140505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the complex linkages between units of variable composition of monolignol and the heterogeneous and recalcitrant nature of lignin pose a continuing technical challenge to its efficient extraction, depolymerization and conversion into value-added products. Conventional lignin valorization approaches such as thermochemical, chemical, and biochemical routes depend largely on experimental trial-and-error optimization, which is time-consuming and resource-intensive. This review covers the recent advances in the application of artificial intelligence and machine learning (AI/ML) approaches for the valorization of lignin in biorefinery systems. AI/ML methods can be categorized into four types: prediction modelling using tools such as artificial neural networks (ANN), response surface methodology (RSM), tree-based algorithms (e.g., XGBoost) and Gaussian process regression to predict lignin yield, purity, molecular weight distribution, and depolymerization rate. The optimization techniques, such as deep learning, Bayesian optimization, genetic algorithms (GA), evolutionary computing, and particle swarm optimization (PSO) increasingly coupled with hybrid modelling frameworks (e.g., ANN-RSM, ANN-GA, GA-RSM) to improve process efficiency and product quality. The review also covers the coupling of AI/ML-enabled models with techno-economic analysis (TEA) and life cycle assessment (LCA) as a means of evaluating the environmental and economic viability of lignin-derived products at scale. This review, demonstrates that AI/ML-enabled lignin valorization is a promising route for intelligent, data-driven biorefinery systems to maximize yield and improve product quality, and minimize the cost of processing, thus contributing to the transition towards a sustainable bio-circular economy and low-carbon industrial processes.</div></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"13 ","pages":"Article 101074"},"PeriodicalIF":6.4,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149140501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In most traditional engineering practices, water, energy, carbon, and land systems have usually been treated separately. However, this approach is becoming less effective because these systems are closely linked and strongly influence one another. This review brings together recent developments in integrated environmental engineering, focusing on the interaction between smart building systems, atmospheric water harvesting (AWH), circular water–energy processes, carbon capture, utilization and storage (CCUS), and desertification mitigation technologies. A structured literature search was conducted using the Web of Science Core Collection across six predefined thematic domains, covering literature available up to 2026 and identifying 1567 records. After duplicate removal and sequential screening based on predefined eligibility criteria, 74 studies were retained for the final synthesis. Quantitative evidence showed that increasing atmospheric water-harvesting cycles from 2 to 12 per day increased total water production from 1.42 to 2.52 g/g, but reduced sorbent utilization efficiency from 51.4% to 16.4%. In parallel, optimized green hydrogen systems reported production costs of approximately 2.3 USD/kg, while integrated wastewater–hydrogen systems achieved hydrogen purities of 87–96%, alongside up to 70% magnesium removal and complete phosphate recovery in selected configurations. The review explores how smart infrastructure is gradually moving toward more adaptive and energy-aware systems, supported by advanced nano-materials such as MXenes and nano cellulose-based materials. It also discusses recent progress in atmospheric water harvesting, especially sorbent-based systems that can operate under low-humidity conditions, although challenges related to scaling and real-world application are still present. In parallel, wastewater to-energy technologies are reviewed, including photocatalytic and electrochemical approaches used for green hydrogen production within sustainable energy frameworks. The role of CCUS is also considered, particularly its shift toward carbon utilization in addition to storage. Desertification mitigation is further addressed through land restoration strategies and naturebased solutions that are integrated within broader water–energy–land systems. Despite the progress in these areas, there are still important challenges that limit real-world implementation. These include difficulties in integrating different systems together, long-term operational stability, economic feasibility, and scaling technologies beyond laboratory conditions.

Geographic information systems (GIS) were integrated to generate high-resolution spatial inventories across all administrative districts, supporting targeted bioenergy planning and identifying regional biomass co-utilization hotspots for biorefinery siting. Results indicate Bangladesh produces approximately 193.6 million oven-dry tons (ODT) of livestock manure, 64.9 million ODT of agricultural residues, 12.1 million ODT of forest biomass, 6.0 million ODT of MSW, and 1157.8 k ODT of sludge annually.
