Some remain on the ocean's surface; microplastics account for 92% of plastic debris on the ocean's surface, according to a 2018 study. [83] And some sink to the ocean floor. Australia's national science agency CSIRO estimated that 14 million metric tons of microplastics are already on the ocean floor in 2020. [84]
Aside from cleaning the microplastics from the oceans, the Ocean Cleanup is also developing technologies to remove larger pieces of plastic from rivers, which are largely attributed as the main sources of plastic in the ocean. [13]
By the end of 2024, the Ocean Cleanup had removed more than one million pounds of trash from the Great Pacific Garbage Patch, or 0.5% of the total accumulated trash. [7] While microplastics dominate the area by count, 92% of the mass of the patch consists of larger objects which have not yet fragmented into microplastics.
For example, microplastics can be found on sandy beaches [21] and surface waters [22] as well as in the water column and deep sea sediment. Microplastics are also found within the many other types of marine particles such as dead biological material (tissue and shells) and some soil particles (blown in by wind and carried to the ocean by rivers).
Microplastics are extremely difficult to track and clean up through conventional methods Nasa-funded mission tracks ocean microplastics from space Skip to main content
Beach cleaning or clean-up is the process of removing solid litter, dense chemicals, and organic debris deposited on a beach or coastline by the tide, local visitors, or tourists. Humans pollute beaches with materials such as plastic bottles and bags , plastic straws , fishing gear , cigarette filters , six-pack rings , surgical masks and many ...

The Ocean Cleanup is a nonprofit environmental engineering organization based in the Netherlands that develops and deploys technology to extract plastic pollution from the oceans and to capture it in rivers before it can reach the ocean. Their initial focus was on the Pacific Ocean and its garbage patch, and extended to rivers in countries ...
