Накратко на български

Индустриални отпадъци като рециклиран бетон и минни остатъци се изследват за улавяне на въглероден диоксид. Това помага за намаляване на емисиите от строителния сектор и насърчава кръговата икономика.

Valorization of CO2 for low carbon cement

The project addresses the urgent need to reduce the environmental impact of the cement and construction sectors, which are among the largest contributors to global CO2 emissions. In particular, the work focuses on developing innovative carbonation strategies that valorize industrial by-products such as recycled concrete and mine tailings. By transforming these waste streams into valuable carbon-storing materials, the project seeks to advance both climate change mitigation and the circular economy. To achieve this, three scientific objectives were defined, each embedded in a dedicated work package with clear performance metrics. These objectives remain highly relevant and continue to guide the research effort: 1. Material characterization – Understanding and optimizing the carbonation behavior of recycled concrete and mine tailings. 2. Technical equipment development – Designing and testing suitable equipment for dry, semi-dry, and wet carbonation. 3. Process modelling – Developing kinetic models and process simulations to evaluate alternative process configurations and their techno-economic feasibility. The research pathway has been structured to ensure both scientific rigor and practical impact. The project began with comprehensive literature reviews carried out by each doctoral candidate (DC), forming the basis for the design of novel experimental systems and computational models. This approach ensured that the overarching project objectives were translated into detailed, university-aligned PhD research plans.

Цел на проекта

Cement production is responsible for 8% of global CO2 emissions, which mainly come from the processing of limestone. CO2Valorize proposes a new approach to drastically reduce these emissions by partly replacing some of the limestone content with supplementary cementitious materials (SCM). Such materials are additionally carbonated using captured CO2, so this part-replacement process utilises captured CO2. Promising, calcium silicates rich SCM can come from waste materials such as mine tailings and recycled concrete, all of which are available in large quantities. The carbonation process of such materials is complex and barely understood to date. Our networks aim to lay the scientific foundations to create fundamental knowledge on the mechanisms, reaction kinetics, the physico-chemical subprocess, and the performance of the modified cement in order to provide a proof-of-concept and show that a CO2 reduction by 50 % per tonne of cement produced is feasible. The project is driven by leading companies that represent important parts of the value chain and ensure a fast uptake of the results with the potential to commercialise new equipment, processes and software during and after the project. The structured approach combines complementary research for each individual project in the academic and industry sector. This is accompanied by a balanced mix of high-level scientific courses and transferable skills delivered by each partner locally and in dedicated training schools and workshops at network level. This way, each doctoral candidate builds up deep scientific expertise and interdisciplinary knowledge to deliver game-changing cleantech innovations during and after the project. CO2Valorize is impact-driven and strives for portfolios of high-class joint publications in leading journals and patents. The transfer of the results into first-of-its-kind engineering solutions contribute to the next generation of cement processes that can mitigate climate change.
