They are called Seabins and these trash cans promise to clean up the world's oceans as they collect floating garbage like plastic and fuel in the floating docks of marinas, harbors yacht clubs and other similar waterways where the winds and currents caused garbage to drift toward these areas.
and is connected to a shore-based water pump
that sucks water through the bin
where a natural fiber bag
is used to collect the floating garbage.
After the garbage is filtered out,
the seawater can be further cleaned
by using a water/oil separator
before it can be pumped back into the ocean.
