The project started by the analysis of the issue. During two months of data and information collection in Jakarta the magnitude of the issue and main causes were clear. Activities to collect the plastic from the Ocean are not sufficient, if we want to solve the issue, we have first to stop the sources. The result of the study clearly showed us that the rivers are one of the principal ways that allow plastic enteric the Oceans. That’s why we started looking for a solution for stopping plastic waste in rivers before they reach and pollute our Oceans.
