This bin could help suck the ocean clean

Rubbish floats in the Govan Graving Docks in Glasgow, Scotland January 15, 2014. The British shipbuilding industry has been through a turbulent time after defence contractor BAE Systems announced in November that it planned to lay off 1,775 ship workers across the UK. The cuts signal the end of more than 500 years of shipbuilding in Portsmouth on England's south coast. BAE is set to continue constructing ships in Glasgow, but showy entertainment venues, museums and new housing blocks have replaced many of the shipyards that once lined the city’s famous River Clyde. Long gone are the days when the area was an industrial powerhouse producing around a fifth of the world's ships. Now Glasgow promotes itself instead as a financial and commercial hub – although it still struggles with high unemployment. Picture taken January 15, 2014.

Innovation

Polluted waters

Every year, 8 million metric tons of discarded plastic find their way into Earth’s oceans. In the past, a majority of this debris was organic material, but that has since been replaced primarily by plastic. One technology, the “seabin,” aims to combat this problem—and the U.K. just installed its first one.

The seabin is, as its name suggests, a bin made up of a large fiber net and a dock-based pump. The device is aimed at collecting pollution of all sizes, down to floating debris as small as 2mm in diameter. It’s even capable of collecting oil from the water, a priceless innovation in the event of an oil spill.

The first implemented seabin was installed this month in Portsmouth Harbor in the U.K, where it will be able to immediately start cleaning plastic pollution from its waters.

“Sure, we can’t catch everything right now, but it’s a really positive start,” the device’s creators, Pete Ceglinski and Andrew Turto, told the Huffington Post. “It’s a big mission, but it can be done. In fact, we’re doing it right now.”

Cleaning plastic pollution

The seabin works by creating a flow of water into the bin, bringing with it any surrounding debris that is then caught in the net. According to the Seabin Project website, the device can catch 1.5 kilograms (about 3.3 pounds) of debris per day, with the ability to hold up to 12 kilograms (26.5 pounds) at full capacity. The creators estimate each seabin can remove about half a ton of debris every year, the equivalent of collecting about 20,000 bottles or 83,000 plastic bags.

This technology was so promising that its creators were able to raise $260,000 on IndieGoGo to fund its creation.

The seabin is set to become commercially available this November. If its installment in the U.K. proves successful, others will catch on and adopt the technology—indeed, other efforts are already underway, and with little time to lose. If left in place, ocean plastic can injure and starve animals, release toxins into creatures that eat it, and even end up in our food and in our water. Global adoption of plastic-collecting technology could make a serious dent in this worldwide issue we are facing.
