Description

Microplastic removal device {apparatus for removal of microplastic}

The present invention relates to a device for removing microplastics, and more particularly, to a device for removing microplastics in which the accuracy of collecting microplastics is improved.

In recent years, millions of tons of plastics are introduced into the ocean every year worldwide, and plastics are decomposed into microplastics by weathering in the ocean, abrasion by waves, and ultraviolet radiation.

In particular, widespread plastic intake has been documented in birds and turtles, with at least 44% of marine algae consuming plastics, such as the proven black-footed albatross (phoebastria nigripes), which feeds chunks of plastic to its offspring.

Moreover, microplastics have the ability to adsorb, release, and transport toxic substances such as POPs, and have been reported to be ingested by both vertebrates and invertebrates, and bioaccumulation is highly likely to occur. Therefore, management of marine plastic waste is urgent.

In particular, there is a serious problem that the marine ecosystem around the beach is damaged as microplastics floating in the sea are stacked on the beach by algae or waves.

However, in the case of Korea, despite the serious level of microplastic pollution, there is no specific plan for the collection of microplastics stacked on the beach.
