Trash Trawl
PortBin TrashTrawl collects floating marine waste from rivers.
It is based on the same principles of a high speed boom system from oilspill recovery world.
It will collect larger volumes of waste cleverly using the river current itself.
No external energy needed. It is not hindering boats and other traffic on the river.
The waste ends up in large mesh sacks, easily emptied when filled up.
