I'm not sure that's the answer. I got an eye-opening view of the problem when I took a trip to Southeast Asia a couple years ago. Being in the third world, there's very few recycling plants to process plastic waste. The next best option, as you've implied, is landfills to sequester plastic waste...sacrifice that land to keep the rest of our planet clean(er). But even that's hard in many places. On many of the islands I visited, people did make a conscientious effort to throw their plastic garbage in bins and do the right thing. And that worked great, up until one of the massive deluges of rain that the area gets would come. And since they had no landfill area that was far enough from the water, the rains would wash the entire landfills out to sea in a massive river of plastic waste. It was one of the most depressing sights I've ever seen. On one of the scuba dives I went on, we found ourselves surfacing in a debris field that had washed out to sea and it was astonishing to see the magnitude of it. Collecting everything together, as in your suggestion, just led to a massive batch dump into the ocean and it didn't do anything to keep the waste out of the ocean. What we really need is a way to simply produce less plastic products. Increased use of glass, increased emphasis on reusing what plastic we do have and, yes, new technology to replace plastics with materials that break down faster so that when they do end up in the oceans, which in much of the world is inevitable from the moment of creation, they don't cause the amount of damage that plastics do.
