On November 26, 2025, the Center of Competence “Clean&Circle” opened the doors of its equipped laboratories for the first time in its new building at the “Lozenets” academic campus. The event took place as an Open Day titled “Discover Clean&Circle”, attracting representatives of the academic community, institutions, partner organizations, and guests.

Center of Competence “Clean&Circle” is glad to announce the visit of Dr. Ludmila Cechova as part of our collaboration with Central European Institute of Technology (CEITEC) of the Czech Republic:

Every sip of clean drinking water is HEALTH, LIFE AND LONGEVITY! When we drink it, we feel both TASTE and AROMA that pleasantly captivate us.

Scientists and researchers from the Clean&Circle Center of Competence, together with the laboratory research complex of Sofiyska Voda AD, conducted extensive studies on the “bloom” of the waters of the Iskar Reservoir and how this affects the smell of drinking water in the water supply network during May–June 2025. They found that the development of a larger amount of phytoplankton in the Iskar Reservoir this year is due to the specific combination of physicochemical and biological factors influencing the characteristics of the water entering the treatment plant. Based on their findings, important decisions were made at critical control points along the entire technological chain, and rehabilitation measures were carried out in the sand filtration units. These measures led to a rapid restoration of the taste and odor of the drinking water.

The team from IOHCF-BAS – Prof. DSc P. Dolashka, Prof. Dr. L. Velkova, Assoc. Prof. Dr. A. Dolashki, Dr. M. Kermedchiev, and A. Stankova – took an active part with a series of scientific presentations at the prestigious international forum 12th International Conference on Materials Science and Engineering, held on 25–26 September 2025 in London. The participants presented the latest results of their research focused on environmental protection, the development of sustainable materials, and the implementation of circular economy principles.
