10 September 2022 – Graduates from the first batch of the Marine Plastics Abatement (MPA) program published a journal article titled “Fate identification and management strategies of non-recyclable plastic waste through the integration of material flow analysis and leakage hotspot modeling” in Scientific Reports, a top scientific journal in the field. Aprilia Nidia Rinasti and Indradhi Faisal Ibrahim developed the article as a result of research conducted during their study program, supervised by Prof. Thammarat Koottatep, Dr. Ekbordin Winijkul, and Dr. Kavinda Gunasekara. During their study, Aprilia and Indradhi compiled different perspectives to define plastic leakage into the environment from the spatial and waste management assessment. They further developed a control mechanism for plastic waste in two cities in Indonesia.

Using analysis from Waste Flow Diagram (WFD) and Geographic Information Systems (GIS), the study found that more than 1,000 tons of plastic waste accumulated annually in the main rivers in the Greater Jakarta Area and Bandung City, Indonesia. Focusing on non-recyclable plastic, the study identified that almost 25% of the plastic waste is leaked into the open environment, half of which ends up in the Ciliwung and Cikapundung rivers. They concluded that improving the waste segregation system is key to increasing plastic circularity to prevent plastic leakage, while GIS modeling can help identify existing leakage hotspots that need to be addressed.
