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) took place from the 18th to the 23rd of September 2022 in Busan, Republic of Korea.

The 7IMDC built 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 was 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).


Participants were able to submit abstracts and posters, attend technical sessions and join field activities to learn more about marine litter and plastic pollution.


There was many opportunities to network, exchange ideas and learn from each other throughout 7IMDC.


Get inspired by attending exhibitions, movie nights, poster competition, learning how to go zero waste and much more!


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

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