A young Dutch inventor, Boyan Slat, at the age of 18, has developed a floating device (设备) to stop plastic waste moving into rivers before it reaches the seas. In the same year, he also founded an environmental group called The Ocean Cleanup. Its purpose is to develop the system and move it to the right place, then get it ready for use.

Recently, the 25-year-old Slat announced the next step in his fight: a floating device that he called “Interceptor”. It can remove plastic out of rivers. The device is powered by energy from the sun.

“We need to close the tap, which means preventing more plastic from reaching the ocean in the first place,” Slat said. He added the waste from land to sea was carried mainly through rivers.

Experts say 8 million metric tons of waste flowing into the oceans each year are from rivers, creeks (小溪) and seaside areas. The plastic endangers fish and other sea living things. Three of the machines have already been moved to Indonesia, Malaysia and Vietnam. Slat said a fourth was going to the Dominican Republic.

Slat said he believed 1,000 rivers were responsible for about 80% of the plastic going into the world’s oceans. He said he wanted to try to clean up the plastic bottles and other rubbish in the next five years.

He added, “This is not going to be easy, but imagine if we do get this done, we could truly make our oceans clean again.”

Slat showed how it worked by putting hundreds of yellow rubber ducks into the water at the launch event in the Dutch city of Rotterdam. Interceptor caught almost all of them.

Jan Van Franeker is with the Wageningen Marine Research Institute. He told the The Associated Press(AP), “I am really happy they finally moved towards the source of the litter. The design, from what I can see, looks pretty good. ”
