Removing the vast amounts of plastic waste already polluting our oceans is going to need tackling in a number of ways. But the flow of plastic from rivers also needs to be stopped, and that’s what Vietnam’s trash traps are designed to do.
They may not look quite as swanky as the Interceptors from the Ocean Cleanup, but the idea is similar. The first in a series of trash traps installed along Vietnam’s Song Hong, the country’s second-longest river (also known as the Red River), is designed to remove floating debris from the water as it flows towards the Gulf of Tonkin.
Where the Ocean Project’s Interceptor is a barge-like vessel designed to remove plastic as it patrols rivers, the trash trap features floating booms and platforms connected to the riverbank.
During the grant period, a local team will remove and sort trapped debris every three days. Plastic waste such as bottles will be sold to recycling facilities, while lower-grade plastic from the likes of bags and films will be processed at a special facility in Nam Dinh. Data on the operation will be analyzed by members of the Ocean Conservancy and Vietnamese scientists to inform future waste strategies.
It doesn’t appear that the solution is designed to deal with microplastics, but with MCD looking to build a network of traps in the Song Hong delta, it could help stem the tide of plastic waste entering the seas and oceans from Vietnam’s rivers.
