The CLUSKER project and its ceramic tiles that improve indoor air quality are backed by ERDF funding
At Topciment®, we've done it again. We have developed a new initiative from a sustainable perspective that positively impacts the construction sector—an initiative that reinforces our strong commitment to building a more sustainable and therefore responsible future.
The quality of the air we breathe has a direct impact on our well-being. This impact becomes even more critical indoors, where we spend most of our time and where providing proper ventilation is essential. But that alone is not enough. That's why we are going one step further with an innovative approach perfectly embodied in our "CLUSKER" project which guarantees safer and more sustainable spaces.
In this project, we demonstrate how the inclusion of advanced ceramic tiles with antimicrobial properties significantly improves air quality. By applying the most innovative—yet also sustainable—technology, microorganisms and unpleasant odours are completely eliminated. A viable proposal made possible through the generation of singlet oxygen activated by visible light.
The "CLUSKER" project, under file number INNCAD/2024/415, has been funded almost entirely by the Comunitat Valenciana Programme of the European Regional Development Fund (ERDF) 2021–2027, which contributed €145,354.31 out of the total €181,692.88 investment.

Objectives behind the "CLUSKER" project
Below, we outline point by point the four main objectives pursued with the public introduction of the "CLUSKER" project:
- Development of antimicrobial and deodorising ceramic coatings. These materials are based on photoactive molybdenum clusters as well as on advanced adsorbent materials (MOFs and zeolites).
- Application of various sustainable technologies, such as mechanochemistry, involved in the production of the materials included in this project.
- Verification of antifungal and deodorising efficacy in real-world environments and how this process is integrated into the ceramic industry.
- Optimisation for commercial viability. How? By ensuring a low carbon footprint and sustainability.
Results obtained from the "CLUSKER" project
The core focus of the project was the development of a prototype ceramic tile with a functional coating, validated through various functional tests involving molybdenum clusters and adsorbent materials. The experiment was a complete success, achieving effective odour adsorption and microorganism elimination through photocatalysis under real-life conditions.
To achieve this, a multidisciplinary consortium was formed involving various companies and research centres. Among them were Keraben Grupo, AIMPLAS, CSIC, and Universitat Jaume I.
