Gossips checked with DPW Superintendent Rob Perry, and here's the answer. We don't have to separate glass, metal, plastic, and paper anymore because, since August, Columbia County has been transporting recyclables directly to a "single stream" facility which separates glass, metal, plastic, and paper for us. This makes several things possible. Residents can put all their recycling into the same bin. DPW can pick up the recycling with the garbage truck, which has a greater capacity than the recycling truck. Collecting recyclables can be done in half the time. So starting next week--at the beginning of the new year--the recycling for the entire city will be picked up on Thursday.
Meanwhile, those of us accustomed to separating recyclables need to have faith that down the line there's an automated process doing the separating for us.
