If we assume a business as usual projection with growing populations, increasing plastic consumption and increased waste generation, by 2025, this number doubles - we may be adding 17.5 million metric tons of plastic per year. As early as 2010, Tara Expeditions Foundation was one of the first bodies to undertake a scientific examination of . WHEREAS, roughly 8 million metric tons of plastic are estimated to enter the world's oceans from land each yeari by washing into rivers and flowing with the water to the ocean; and WHEREAS, according to the Ocean Conservancy, plastic bags are among the top ten items . 347:6223, pp . We calculate that 275 million metric tons (MT) of plastic waste was generated in 192 coastal countries in 2010, with 4.8 to 12.7 million MT entering 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. The first evidence of this issue began to appear in literature in the 1970s (Jambeck et al., 2015, p. 768), yet here we are nearly 40 years later and still very little has been done to alleviate the problem. Abstract Marine plastics pollution (MPP) is an alarming problem affecting many countries, particularly in the Asia-Pacific region, and generated mostly from land-based sources. Downloads.

The amount of plastic waste entering the oceans from land each year exceeds 4.8 million tons (Mt), and may be as high as 12.7 Mt - or nearly one to three orders of magnitude greater than the reported mass of plastic in high-concentration ocean gyres. By Marjaleen Ramos. Mar. 2015. Qinqin, C. et. Plastic waste inputs from land into the ocean. The team made assumptions about waste generation and probable plastics use in coastal populations around the world. There are 5,250 billion* plastic particles floating on the surface on the world's seas and oceans, equivalent to 268,940 metric tons of waste. Plastic waste inputs from land into the ocean. Land-based sources are considered the dominant input of plastics into the ocean. Industry-led or reduce demand 2. Estimates reflect assumed conversion rates of mismanaged plastic waste to marine debris (high, 40%; mid, 25%; low, 15%). Land-based sources, as opposed to marine-based sources, are considered the dominant input of plastics into oceans 4. 1. We calculate that 275 million metric tons (MT) of plastic waste was generated in 192 coastal . China, Indonesia, the Philippines, Vietnam and Sri Lanka) have been identified as the largest sources of MPP globally. (2015). This is the critical finding of a joint report by the Ocean Conservancy and the McKinsey Center for Business and Environment, Stemming the tide: Land-based strategies for a plastic-free ocean.Our comprehensive investigation found that more than 80 percent of ocean plastic comes from land-based sources rather than ocean-based sources such as fisheries and fishing vessels. Estimated mass of mismanaged plastic waste (millions of metric tons) input to the ocean by populations living within 50 km of a coast in 192 countries, plotted as a cumulative sum from 2010 to 2025. Mar. It recommends a national strategy for reducing the U.S. contribution [5] Largely rooted in inadequate waste management practices on land, an estimated 80% of marine litter originates from land . Therefore, this work focuses . Science. Furthermore, our findings indicate that an additional plastic input of at least 0.79-1.52 . This suggests that at least 2.8-18.6% of the coastal plastic emissions occur via river transport. polymers in the ocean should be regarded as hazardous waste [3]. al. By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land-based plastic waste entering the ocean. If current trends continue, oceans could contain more plastic than fish by 20506, 7 . Science 347(6223) . .

By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land-based plastic waste entering the ocean. An estimated 4.8 to 12.7 metric tons of plastic litter enter the ocean every year [4] and despite global initiatives to reduce it, volumes of marine litter continue to increase as the world's consuming population grows. Plastic Waste Inputs from Land Into the Ocean. Five Asian countries (i.e. However, the most conservative estimate for plastic emissions in 2010 was 4.8 million tonnes - two orders of magnitude higher. A well-known paper "Marine Pollution: Plastic Waste Inputs from Land into the Ocean," published in Science, estimated that approximately 8 million metric tons of plastic leaks into our oceans globally each year (Jambeck et al., 2015). According to Plastic Oceans, more than 8 million tons of plastic end up in our oceans each year. While a quantification of land-based inputs from coastal populations (<50 km from coastline) worldwide already exists 5 , no global assessment of contributions from inland populations through riverine systems has been proposed to . 6223, pp. By . plastic waste was generated in 192 coastal countries in 2010, with 4.8. to 12.7 million MT entering the ocean.
