Sure, but if a truck that picked up sorted plastic arrives at the landfill, it's going to be dumped all in one place. If at any time in the future we devise a way to efficiently get rid of it, it's easier to remove it from one single place, than having to sift through tonnes of unsorted trash. I frankly think that an enterprise that can build robots able to sort landfills would make mint.
