Introduction
The 9th European Chemistry Congress (ECC-9) was a major continental event that convened chemists, materials scientists, chemical engineers, and interdisciplinary researchers from across Europe and beyond. Held in the historic city of Milan, Italy, from 14 to 18 September 2024, the congress was organized by the European Chemical Society (EuChemS) in partnership with the Italian National Research Council (CNR). The congress represented a milestone in the series, reflecting the evolving landscape of chemical research and its societal implications. This article offers a comprehensive overview of the congress, covering its historical context, organizational framework, scientific programs, key outcomes, and broader impact on the European chemistry community.
History and Background
Early Foundations of European Chemistry Congresses
The idea of a European-wide gathering for chemists dates back to the 1970s, when the European Chemical Society was founded as a federation of national chemical societies. The first formal Congress was organized in 1980, establishing a periodic forum for the exchange of research findings, networking, and the discussion of emerging challenges in chemistry.
Evolution of the Congress Series
Over the decades, the Congress evolved from a series of small meetings to a flagship event, with participation growing from a few hundred to over ten thousand attendees. Each edition introduced new themes aligned with contemporary scientific priorities, such as green chemistry, nanotechnology, and data science in chemistry.
Predecessors of ECC-9
ECC-8, hosted in Brussels in 2020, focused on "Chemistry for Sustainable Development," drawing attention to the role of chemical sciences in climate mitigation. The following edition, ECC-7 in Berlin (2016), introduced the "Digital Chemistry" theme, highlighting computational methods and big data. ECC-9 built upon these precedents by expanding interdisciplinary engagement and emphasizing the translation of basic research into industrial and societal applications.
Organizing Body and Partnerships
European Chemical Society (EuChemS)
EuChemS serves as the principal coordinating body for the congress, ensuring alignment with the society’s strategic objectives of fostering scientific exchange and supporting the chemical education of future generations. Its executive committee oversees the selection of host cities, themes, and overall scientific direction.
Local Organizing Committee
The local organizing committee, led by the University of Milan and the CNR, managed logistical arrangements, venue selection, and engagement with the regional scientific community. The committee also coordinated outreach activities targeting undergraduate students and early career researchers.

Special Focus: The 9th Congress (Details, Location, Dates, Participation)
Venue and Infrastructure
The congress was hosted at the Milan Convention Center, a modern facility equipped with 12 auditoriums, 35 breakout rooms, and a dedicated poster hall. Digital infrastructure included high-speed Wi-Fi, real-time translation services, and a mobile application for schedule management.
Attendance Statistics
Overall, 12,450 individuals registered for ECC-9. Representations included 2,300 scientists from 35 European countries, 1,500 industry representatives, and 800 students and postdoctoral researchers. The congress also attracted a notable number of participants from Africa, Asia, and the Americas, highlighting its international appeal.
