A Dutch teenager has invented a device that could clean up some 20 billion tonnes of plastic waste from the world's oceans. Boyan Slat, a nineteen-year-old engineering student, was worried about the amount of plastic rubbish that accumulates on the surface of some sea areas, so he came up with the idea of a series of floating barriers and processing platforms designed to collect floating plastic rubbish, while allowing fish and plankton to pass through undamaged. An additional advantage of the system is that the plastic waste collected by these barriers would be stored so that it can be later recycled.
Millions of tonnes of plastic waste are littering oceans and tend to accumulate in specific areas due to sea currents. This litter not only kills millions of aquatic animals annually but also introduces and spreads harmful algae and invasive species. Besides, plastic waste also contains pollutants that can enter the human food chain through fish. The existing methods for cleaning sea water are not very useful and they cost governments and organisations millions of dollars every year.
Boyan Slat believes that humans must drastically reduce their use of plastic items in the near future, but meanwhile his innovation could make a big difference to the cleanliness of oceans in the shorter-term. He thinks that, once operational, his device could dramatically reduce the amount of rubbish in the oceans in just about five years’ time.
Boyan Slat has offered his design to environmental companies and agencies and has already received offers to start producing experimental models of his platforms by the end of this year.
