Fish-like robots collect microplastics in the oceans

The press office of the American Chemical Society has announced the creation of fish-like robots with a speed of 150 meters per hour, whose mission is to collect microplastics in the oceans.

As is known, about 300 million tons of plastic waste are discharged into wastewater, most of which does not decompose in tens or even hundreds of years.

This plastic waste does not stay in the water for long, but is eaten by marine animals, so some of it can reach the human body with the meat of fish, shellfish and crustaceans. The remainder of this waste complicates the process of cleaning up the global ocean of waste.

The chemists were in able to devise a way to clean the oceans of plastic waste using automated robots, similar in size to small fish. These robots are made with graphene sheets glued together with sugary materials. And when the laser beam is directed at these plates, they move in the water in the form of waves, like “flat” fish and marine animals. And sticky or porous materials are installed on their surface, in so they can search for and collect plastic particles.

“These nanorobots are in able to move in water at a speed of 150 meters per hour, which is several times faster than the speed of older robot models. The first test they proved that they are in able to collect a large amount of plastic particles and transport them in another place “, reads the note.

The results of the test some prototypes of these robots have shown that they are in able to resist collisions with other objects. So the innovators hope it will soon begin to be used to clean up the most polluted parts of the world’s oceans.
