Samenvatting

Plastic pollution is a worldwide problem and affects the environment in harmful ways. This research focusses on reducing plastic pollution in rivers and preventing plastic pollution to reach oceans by determining an efficient approach to find convergence areas where plastic catching is the most optimal. For this research a case area is chosen for conducting research on plastic streams in a river that was representative for one of the eight large rivers in Asia that together are responsible for 80% percent of all the plastic entering the oceans every year. The case area that has been chosen is a side branch of the Mekong river delta and is named the Sông Cần Thơ. The aim of this research is to find an approach for finding convergence areas in rivers where plastic catching is the most efficient and the local activities that are part of a river are not affected. Two approaches have been used to determine plastic convergence areas in the Sông Cần Thơ.
