Special Issue Information

Dear Colleagues,

The continuous rise in carbon dioxide (CO₂) emissions, mainly from fossil fuel-based energy production and industrial processes, has led to significant climate change impacts. To combat this, CO₂ capture has emerged as a crucial technology. However, existing CO₂ capture methods face various limitations, spurring the need for new research and innovation. This Special Issue aims to clearly identify and analyze the key challenges in CO₂ capture. This includes technological barriers like low-efficiency capture materials, high-energy-consuming processes, and difficulties in integrating capture systems into existing industrial set-ups. It also seeks to explore the latest research trends. This involves emerging areas such as bio-inspired CO₂ capture, electro-chemical and photochemical methods, and the use of artificial intelligence in optimizing capture processes. Authors are encouraged to submit papers that address these challenges or showcase new research trends. Papers can be experimental, theoretical, or review-based. Experimental papers may present new materials or processes, theoretical papers may offer models for understanding and predicting capture behavior, and review papers may summarize and analyze the current state of the art in CO₂ capture research.

The aim of this study is an interdisciplinary assessment of the potential of cement pastes to permanently bind carbon dioxide (CO2) under anaerobic digestion conditions, considering technological, microstructural, environmental, and economic aspects. The research focused on three types of Portland cement: CEM I 52.5N, CEM I 42.5R-1, and CEM I 42.5R-2, differing in phase composition and reactivity, which were evaluated in terms of their carbonation potential and resistance to chemically aggressive environments. The cement pastes were prepared with a water-to-cement ratio of 0.5 and subjected to 90-day exposure in two environments: a reference environment (tap water) and a fermentation environment (aqueous suspension of poultry manure simulating biogas reactor conditions). XRD, TG/DTA, SEM/EDS, and mercury intrusion porosimetry were applied to analyze CO2 mineralization, phase changes, and microstructural evolution. XRD results revealed a significant increase in calcite content (e.g., for CEM I 52.5N from 5.9% to 41.1%) and the presence of vaterite (19.3%), indicating intense carbonation under organic conditions. TG/DTA analysis confirmed a reduction in portlandite and C-S-H phases, suggesting their transformation into stable carbonate forms. SEM observations and EDS analysis revealed well-developed calcite crystals and the dominance of Ca, C, and O, confirming effective CO2 binding. In control samples, hydration products predominated without signs of mineralization. The highest sequestration potential was observed for CEM I 52.5N, while cements with higher C3A content (e.g., CEM I 42.5R-2) exhibited lower chemical resistance. The results confirm that carbonation under fermentation conditions may serve as an effective tool for CO2 emission management, contributing to improved durability of construction materials and generating measurable economic benefits in the context of climate policy and the EU ETS. The article highlights the need to integrate CO2 sequestration technologies with emission management systems and life cycle assessment (LCA) of biogas infrastructure, supporting the transition toward a low-carbon economy.
