This process continues down to the molecular level.[26] As the plastic flotsam photodegrades into smaller and smaller pieces, it concentrates in the upper water column.

Having read Larry Niven's Ringworld, I'm brought to think of an eerie possibility this might create; that is - what if this currently non-biodegradable material becomes biodegradable? What if the colossal supply of this material (which as a hydrocarbon, had bound-potential-energy in it), over what's going to be a colossally long period of time, gives enough interaction surface that somewhere out there, a bacteria evolves that breaks down plastic?
I hardly expect this would be the collapse of civilization or anything (as depicted in the book), but it really could have some nasty consequences. Plastic is relied on almost for precisely that reason - the fact that it doesn't decay/rust/collapse over time. That's why we use it for stuff like medical implants, safety gloves, food storage, sanitary containers ... you name it. It could lose its un-decayable and its sanitary property in one go.
Kinda like the problem with overuse of antibiotics.
Imagine a small gadget (that would fit under the kitchen counter) that would take your plastic waste and recycle it into a polymer of some sort that can be used as material for 3d printers. Then you can recycle your plastic waste and turn it back into other things. This sort of stuff will make plastic truly valuable (which I think it is) and people will stop littering.
Now I don't know much about plastics so I can't say if that's possible or not.. it would be nice if it was :D
How does the sediment rain in the ocean affect this ?
I would think that if the plastic pollution stopped one day, within a few years most of the plastic would be sequestered at the bottom of the ocean. Even though plastic floats, eventually it gets inside animal bodies which eventually die and rain to the bottom ... yes ?
There's a Vice documentary[1] in which reporters visit the "garbage island". The "garbage island" is not how you imagine it, it's literally an ocean of tiny broken down particles of plastic[2] invisible to the naked eye (when looking at the sea) that are in everything, including the fish. There is no way to remove the plastic through harvesting, the only option would be to filter the sea water which has its own set of problems.
I suspect that the amount of sealife that you would kill while attempting to finely filter that shear volume of sea water would make doing that worse than doing nothing.
Also, that plastic is really the lowest possible grade of plastic that you can imagine. I'd be surprised if it were good for even synthetic mulch in playgrounds.

An impressive undertaking (founded by a 19 year old, no less) that's creating technology to solve this in ~5 years.

Easiest is to just collect it and burn it in a central facility though. Simplified, you can burn everything except PVC (number three).
