Plastics are complex materials composed of diverse chemical mixtures, including additives, processing aids, and non-intentionally added substances (NIAS). Addressing the chemical constituents of plastics is crucial when formulating and executing strategies to mitigate plastic pollution. This presentation will deliver a comprehensive and current examination of the various chemicals present in plastics. Additionally, it will explore the broader implications of these chemical components on the environment, human health and technological systems. The session will also delve into emerging research and regulatory perspectives on managing these chemicals. By integrating scientific insights and policy considerations, this presence aims to stimulate discussion on the future research and governance of chemical pollutants in plastic materials.
Dr. Zhanyun Wang is a Scientist at the Technology & Society Laboratory at the Swiss Federal Laboratories for Materials Science and Technology (EMPA). He is an environmental chemist by training, and his research interests focus primarily on understanding the life cycles and risks of various anthropogenic chemicals in the technosphere and natural environment. He is also very interested in exploring novel and pragmatic approaches to advancing sound chemicals management, enabling a sustainable circular economy, and strengthening the science–policy interface on chemicals and waste. He has published nearly 100 articles in peer-reviewed journals, and has led or contributed to over 15 technical reports by UNEP, OECD, the European Commission and several national governments.
