A new study investigates the main creators of plastic leakage and plastic pollution in seas in three regions

The new report, “Plastic Pollution Hotspotting and Shaping Action: Regional Results from Eastern and Southern Africa, the Mediterranean, and Southeast Asia”, published in the membership Union – IUCN, is an essential step to close the plastic pollution knowledge gaps.

The report shows comparisons of the magnitude of plastic leakage and plastic pollution boom areas. The study which led to this report was conducted across eight locations – Kenya, Mozambique, South Africa, the United Republic of Tanzania, Thailand, Viet Nam, the Republic of Cyprus and Menorca.

CLAIM is on the mission to reduce the extent of this pollution through the innovative technologies created by the scientists that are involved in the project. CLAIM’s main goal is to free the seas and ocean from litter, thus this report contributes with information which is relevant and helpful towards the project.

Important questions explored in this report were:

  • What were the key drivers of plastic leakage found in the eight assessments?
  • How do plastic waste management practices compare?
  • What is the plastic recycling capacity of each pilot site and to what extent is it used to manage domestic and imported plastic waste?
  • Were there common geographic archetypes where plastic leakage is occurring?
  • Which polymers and plastic applications were most prevalent in the polymer hotspots?
  • Which of the hotspot category results were robust enough to use as the basis for targeted interventions?
  • How can the quality and robustness of hotspot results be improved?


In conclusion, the report notes that robust data is what leads to high quality metrics, which in turn lead to actions that result in measurable change. Decision-makers should explore a variety of potential priority actions to generate ideas for complementing policies and implementing genuine on-the-ground change to reduce plastic pollution.
