Here is an idea to sort surface-floating plastics by size directly in the Oceans. It is quite simple and as cheap as possible — as it only use tide-wave forces — to create on-sea plastic-sorting concentric zones working with the natural forces of waves.

➠ Second picture : here is the exposed concept of what I've called "The One-Way-Buoy"
It consist of a classic floating buoy, weighted bellow the sea surface to stay afloat in which an opening is made with a slight slope inside.
Each time a wave pass through it, surface-plastic are brought the other way.
With the size of the opening, we can limit the maximal diameter of passing plastics wastes or conglomerates.
With the slight slope, we can ensure that the wastes go only one way (behind the opening), how so ?
➠ Third picture : general set up of multiples buoys
By creating concentric circle of tightly disposed buoys joint by strong see cable with underneath nets, we could ensure a surface-plastic sorting system working with only tide-wave forces. Sorted waste and conglomerates could not escape back (due to the slop and the nets).
Then, it could be possible to send a boat to extract the plastic wastes. They would be already sorted, which would be extremely useful.
For ecological purpose, tiny red lights could be put underwater to make the fishes flee from the zone :
Accordingly, ecologists and fisheries practitioners can utilize red light to exclude fish from dangerous waters and green light to guide them to ideal habitats, laying the necessary groundwork for the light-driven fish recovery effort. Furthermore, the appropriate light configuration can yield economic benefits through the tradeoff among fish protection, power generation, and investment costs.
