Much of this kind of plastic is not recyclable. Every year, in Southeast Asia and China, 4 to 12 million metric tons of plastic packaging is swept down rivers and ends in the oceans. This is a file from the Wikimedia Commons. Orange text shows ways that these plastics move into the ocean. It is roughly estimated that 80% of the marine debris originates from mismanaged waste on land. Once in the water, plastic debris never fully biodegrades. Plastic waste inputs from land into the ocean. Plastic debris in the marine environment is widely documented, but the quantity of plastic entering the ocean from waste generated on land is unknown. By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land-based plastic waste entering the oce …. Case in point, some 18 billion pounds of plastic waste finds its way from coast to ocean annually, according to the article “Plastic Waste Inputs from Land into the Ocean,” published in 2015 by Jenna Jambeck and her group at the University of Georgia, who looked at data from 192 countries. They can come from a variety of land and ocean-based sources; enter the water in many ways; and impact the ocean and Great Lakes.

The darker the color, the larger the amount. 5 Second, some plastics, such as PVC and polyester, are denser than water and will sink to the ocean floor. Science, this issue p. 768 Millions of tons of plastic waste end up in our oceans every year. And even then, they just splinter into very small pieces called microplastics, which will likely never biodegrade. First, the recent discovery of 17.6 tonnes of plastic washed up on the most remote island in the world – Henderson Island in the South Pacific – highlights how plastic can return to land unchecked (Figure 3). Figure 2: Map of Mismanagement of Plastic Waste. A staggering 2.7 million tons of plastic waste are generated in the Philippines each year, 20 percent of which is estimated to end up in the ocean (McKinsey, 2015).
