Such facilities do exist, dirty and/or wet material recovery facility is the search term you'd want. Most material recovery facilities want a clean input stream though. It's not particularly lucrative, but it often makes sense for a landfill operator to do material separation, because the combination of selling the separated material and not using the landfill space makes financial sense. Given that my county landfill is the beneficiary and will either need more tax money or close down and increase my disposal costs, separating the saleable stuff into a clean stream doesn't bother me too much.
