Fact-finding Survey through Joint Research

Prof. Takanobu Inoue of Toyohashi University of Technology conducted a joint research project with his research team entitled "Estimation of amount of release of plastics to the ocean in Indonesia" (2019-2022) under bilateral cooperative programs of the Japan Society for the Promotion of Science. In Jakarta (Indonesia), waste being carried downstream is trapped by a floating contraption involving floats attached to the top of fence posts across the river. The collected garbage was sorted to clarify how much plastic was in the waste. As a result, some 78% was deemed to be plastic, equating to an estimated daily discharge rate of 7.7 - 12.6 grams per person that would eventually find its way to the ocean.
