Current system that have been design and proposed for solving the macro-plastics pollution in the sea are based in a static design that works like a floating barrier that contains the plastic using the natural currents and uses a mechanism similar to a conveyor belt to extract those solids from the water and then those need to be deposited in a ship that needs to travel back and forth with the load.
The advantages of ARPOP over these systems are:
Conceptual thinking and 3d Modelling
Geo-Localization of accumulated plastic wastes in the ocean.
