This study presents a green and innovative approach that utilizes flue gas as a sustainable feedstock for skim rubber production via microbubble-assisted coagulation, addressing these critical challenges. Coagulation and de-ammonization of skim latex using different flue gas components (CO₂, SO₂, and NO_x) via the microbubble process were discussed. The microstructural, physical, and mechanical properties of skim rubber coagulated with microbubbles containing different flue gas components (CO₂, SO₂, and NO_x) were systematically compared with those obtained from the conventional process. Results demonstrated that microbubble-coagulated skim rubber exhibited enhanced physical and mechanical properties compared to conventionally coagulated samples. The process reduces costs, minimizes effluent discharge, and lowers air pollution, offering a sustainable solution to both flue gas utilization and limitations of conventional coagulation.</div></div>","PeriodicalId":350,"journal":{"name":"Journal of CO2 Utilization","volume":"104 ","pages":"Article 103321"},"PeriodicalIF":8.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145923587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assesses various CO₂ utilization pathways aligned with Saudi Vision 2030 and the Circular Carbon Economy, using a multi-criteria decision analysis framework to rank options by maturity, scalability, cost, sequestration potential, and policy fit. Among 9 assessed pathways, CCU for construction materials, such as concrete curing and carbonated aggregates rank highest due to their high technology readiness level (TRL 8–9), economic scalability, and potential for permanent CO₂ sequestration. It is estimated that around 4.7 Mt CO₂/y can be utilized in existing concrete plants across the Kingdom by 2030 with retrofitting costs of around $0.5 M to 1.5 M per site. Our analysis highlights that CO₂-derived fuels like synthetic methane and sustainable aviation fuels offer long-term decarbonization potential, especially when combined with DAC or biogenic CO₂ for net-negative emissions. However, they face challenges such as high energy demand, infrastructure needs, and abatement costs of $430–$650 per tonne of CO₂. Chemical conversion routes (e.g., formic acid, DMC, polyols, cyclic carbonates) have moderate maturity (TRL 4–6) and require substantial R&amp;D investment. Though aligned with Vision 2030, their high costs and carbon leakage risks limit short-term viability. Algae-based utilization offers up to 2 tCO₂ sequestered per tonne of biomass but remains in early stages. Despite these challenges, Saudi Arabia has the potential to lead regionally in CCU by leveraging its industrial base, low-cost renewables, and policy momentum to advance impactful circular carbon solutions.</div></div>","PeriodicalId":350,"journal":{"name":"Journal of CO2 Utilization","volume":"104 ","pages":"Article 103307"},"PeriodicalIF":8.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145898065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various solid sorbents, metal-organic frameworks (MOFs) combined with newly emerging two-dimensional (2D) nanomaterials, Ti₃C₂T_x-MXene, have attracted significant attention owing to their higher porosity, tunable structures, and large surface areas and physisorption mechanism. In this study, we describe the utilization of 2D Ti₃C₂T_x-MXene anchored on MIL-101(Cr) MOF in solid form to evaluate their CO₂ adsorption performance using a fixed-bed adsorption column. Advanced characterization of the as-produced adsorbent is conducted using XRD, FTIR, SEM with EDS, TGA, and BET analysis to assess their surface morphology, surface groups, chemical composition, and surface properties. The synthesized composite showed a BET surface area of 2138 m²/g and a pore volume of ∼1.34 cm³/g. In the adsorption column, CO₂ breakthrough measurements were performed by a continuous CO₂ concentration (15 %) with an inlet flow of 40 mL/min at 1 atm and 25 °C. The CO₂ adsorption capacity (∼21 mg/g) was achieved by Ti₃C₂T_x-MXene/MIL-101 (Cr) at ambient conditions. This corresponds to ∼50 % better performance than pristine MIL-101 (Cr) at similar conditions. Moreover, the Ti₃C₂T_x-MXene/MIL-101 (Cr) offers good regeneration performance with no significant loss in CO₂ adsorption capacity in regenerative cycles. Finally, the novel work with good CO₂ adsorption results opens a new window of implications of emerging nanomaterials as a promising material platform for CO₂ capture applications for further investigation under direct air capture conditions (ultra-low CO₂ concentrations).</div></div>","PeriodicalId":350,"journal":{"name":"Journal of CO2 Utilization","volume":"104 ","pages":"Article 103322"},"PeriodicalIF":8.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145974107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we systematically examined the effects of nitrogen content and surface area on CO₂ adsorption capacity using a data-driven statistical approach. A comprehensive dataset of 1215 experimental data points compiled from 100 publications was analyzed through correlation analysis, multiple linear regression, and mediation analysis. The results reveal that nitrogen content and surface area are interrelated and may exert competing effects on adsorption. Multiple linear regression confirms that surface area exerts a substantially greater influence on CO₂ adsorption than nitrogen content, as indicated by higher standardized regression coefficients at both 273 K and 298 K. Mediation analysis further demonstrates that the influence of nitrogen on CO₂ adsorption occurs predominantly indirectly through its modification of surface area, with mediated proportions of 70.1 % and 58.2 %, respectively. A comparative evaluation of nitrogen-doped and undoped carbons supports these findings, showing consistent positive correlations between surface area and CO₂ adsorption capacity regardless of nitrogen incorporation.

This study addressed these constraints by modeling a fully integrated DAC–SOEC–FT diesel system using a commercial, equation-oriented simulation platform under steady-state conditions and assuming that renewable power supplied the SOEC unit. The process design incorporated thermal and process-level integration with waste heat from the calciner, FT reactor, and SOEC burner repurposed for internal heating and feed conditioning.
