A Floating Debris Trap (also Floating GPT and Litter Boom) is a device consisting of a partly submerged floating boom positioned in a waterway that is designed to trap highly buoyant and visible pollutants such as plastic bottles.
The boom collects floating objects as they collide with it. Newer designs use floating polyethylene boom arms with fitted skirts to deflect floating debris through a flap gate into a storage compartment. Floating booms are not suited to fast moving waters. Additionally, the traps miss most of the gross pollutant load because only a small fraction of gross pollution remains buoyant for a significant length of time.
