The project, dubbed ‘X-SeeO2,’ consists of a coalition of leading institutions. Alongside UMA, the consortium includes the prestigious universities of Bath and Manchester from the United Kingdom, as well as the European Synchrotron Radiation Facility (ESRF) based in France. Their combined expertise seeks to accelerate the adoption of cements as carbon dioxide sinks, a pivotal strategy in the global fight against pollution and climate change. This goal aligns with increasing international recognition of cement’s potential in impacting greenhouse gas emissions positively.

In the recent Horizon Europe call, only a small fraction of projects were funded, highlighting the intense competition and rigorous evaluation processes involved. Out of approximately 80 applications for the ‘Cement as Carbon Sinks’ challenge, only six were chosen, yielding a mere 7.5 percent success rate. Such statistics underline the high standards and scientific ingenuity synonymous with this initiative, led by Miguel Ángel García Aranda, professor of inorganic chemistry at UMA.

García Aranda’s team aims to develop innovative cements that can sequester carbon dioxide effectively while maintaining the essential properties of concrete. Emphasizing the balance between performance and sustainability, the researchers endeavor to formulate cements that could lower their carbon footprint by at least 50 percent. The initiative is not only a significant leap towards reducing emissions but also a critical point of collaboration with other selected projects, as reported by the University of Malaga.

The focus on cement as a carbon sink is not merely an academic endeavor but a response to the escalating urgency surrounding climate change. Garcia Aranda elucidates the importance of this research in developing smarter concrete materials capable of absorbing carbon dioxide during hydration and subsequent curing processes. The insights gained from studying these cementitious materials will be instrumental in shaping future construction techniques and materials, which will significantly contribute to global emissions reduction efforts.

One of the essential techniques that will underpin the research is real-time X-ray diffraction, combined with microstructure imaging. These advanced analytical techniques will allow for a deeper understanding of the transformation of cementitious materials, enhancing the efficiency of converting them into effective CO2 sinks. As a field-leading institution in X-ray powder diffraction and synchrotron techniques, UMA aims to leverage its expertise to push the boundaries of current construction material science.

This collaborative model signifies a shift in research dynamics, where knowledge is shared across various initiatives, enhancing collective outcomes in battling climate change and contributing to sustainability.

Further emphasizing this transformative approach is the position of María de los Ángeles Gómez de la Torre, another distinguished researcher in the consortium. Her insights into cement improvement and sustainability echo the project’s overarching theme of circular economy principles, with an emphasis on upcycling waste materials into viable construction alternatives. The collaboration exemplifies how academia can harness collective intelligence to address global challenges.

Moreover, the collaboration within the X-SeeO2 project presents an opportunity for knowledge-sharing that can lead to unprecedented innovations. The unique synergies generated by the project will not only benefit the immediate team but will also enrich the entire cohort of EIC projects under the same challenge, paving the way for holistic solutions that are both environmentally and technologically advanced.

Involved in the Horizon Europe programme for several years, UMA’s participation in prior EU-funded projects, such as ‘Zeus’ and ‘BioRobot-MiniHeart’, reflects its proactive approach to tackling pressing research questions. However, no initiative has prepared the university for a leadership role until now, marking a pivotal transition in its research strategy, particularly in cement science and construction materials.
