The Problems / The proposed solution

Ocean Plastic Pollution

Plastic pollution is recently become the major problem in the waste management, since there are around 275 million metric tons of them generated around the world in 2010. Indonesia itself is the second biggest source contributor of plastic waste in the ocean, with an estimation of 0.48 – 1.29 million metric tons in 2010[1]. Why does the plastic waste end up in the ocean? Mismanagement of the plastic waste in the landfill is one of the major cause. The plastics can be carried by wind and rain into rivers, then flow into the sea. Many rivers around the world carry about 1.15-2.41 million tons of plastic waste, transporting them into the ocean [2]. One of the real-world examples happen around our city, Bandung, in the landfill of Sarimukti. The majority of the waste is plastics, stacked into mountains of dirt and trash. When the rainy season is coming, the rain washed out the plastics left behind by the treatment facility into the river nearby. Eventually, these are the plastics that will reach the ocean.

Microplastics

After reaching the ocean, the plastic waste is available in many forms. It can be found at the surface, in the depths, even in the sediment. Plastic bags need up to 20 years to break down completely, while plastic bottles need a hefty 450 years to break down. But actually, one of the pressing concerns is the microplastics. Microplastics formation is caused by combination of physical, chemical, and biological processes. Using modelling approach, it has been estimated that around 15-51 trillion microplastic particles have accumulated in the ocean [3].
