> The cleanup installation showed promising results, but most researchers agree efforts should also be put toward preventing plastic from entering the ocean in the first place. The Ocean Cleanup are also researching that with their 'Interceptors'. https://youtu.be/bm1rH70wfJo |

Eventually we'll have ocean-faring station keeping barge "interceptors". With wave glider style propulsion. https://www.liquid-robotics.com/wave-glider/overview/
Plastic will be captured as shown in video; slowly enough for critters to scoot away.
Their belly's will bail the detritus. Larger barges will collect the bounty, service the interceptors, and so forth.
Barges will have bioreactors reduce the plastics to feed stocks. Then either sell the harvest. Or pump it back into the ground (for carbon capture credits).

For collecting microplastics, we'll have various submersibles. Which mimic jelly fish, baleen whales, and the like. They'll rise to the surface for collection.
Submersibles will have membranes which preferentially extract plastic from water, allowing organisms to go about their way.
###
These plastic harvesters have to be simple, durable, and tenacious. Not necessarily efficient.
With a hundred thousand interceptors, jelly fish, whales slowly, tirelessly cleaning our oceans, I'm certain we can reach Ocean Cleanup's goal (remove 90% of plastic by 2040).
