Welcome to the official website of the 7th International Marine Debris Conference (7IMDC), the world’s longest-running international conference series dedicated to the issue of marine litter and plastic pollution. The 7th International Marine DebrisConference (7IMDC) will take place from the 18th to the 23rd of September 2022 in Busan, Republic of Korea.

The 7IMDC is building on the momentum of past IMDCs by bringing together governments, industry, academia, civil society, and all relevant stakeholders, to discuss the latest science, strengthen collaborations, find solutions and catalyze action to address the urgent, global problem of marine litter and plastic pollution.

The 7IMDC is being organized by an Executive Committee comprised of the Ministry of Oceans and Fisheries of the Republic of Korea (MOF) and the United Nations Environment Programme (UNEP),​ with the organizational support of ​the Korea Marine Environment Management Corporation (KOEM), and the technical support of​ U.S. National Oceanic and Atmospheric Administration (NOAA).

We encourage anyone interested in the 7IMDC to subscribe to the mailing list in order to receive all the latest updates on the conference.

Thank you for your interest in the 7IMDC. We look forward to welcoming you to Busan in September 2022.

The 7IMDC will be optimized to be primarily an in-person event, however the conference will have hybrid elements and will provide options for remote attendance to the substantive portions (such as the Technical Sessions). Session chairs and presenters will be kindly requested to attend the conference in-person if possible, however should this not be possible then pre-recorded presentations will be preferred over real-time remote presentations, to avoid issues with internet connectivity. More guidance will be made available in due time.

The Executive Committee of the 7IMDC continues to closely monitor the public health situation in Busan, in the Republic of Korea, and in the world, and will take all applicable precautions to prevent the spread of COVID-19 at the conference.
