The plan name is Snake- shaped lift, because rails and lifts service in spiral form. According to pictures, material carriers move towards buildings using large and small rails after filling from service plants and eventually return to the same place by the same rails after emptying. Recycling plants act in the opposite way. They send empty carriers towards homes and eventually receive sorted waste. The main picture is a hypothetical figure of buildings, plants, rails and lifts. The second picture is the service plan of plants. The third picture is the motion plan of empty waste carriers towards houses to get waste.
