Abstract
A separation system includes an air separator that in one embodiment primarily receives Municipal Solid Waste (MSW) containing relatively light MSW recyclable materials such as paper, cardboard, plastic containers, and/or metal containers. The air separator blows the relatively light MSW recyclable materials up though a chamber and onto a first conveyer while the other relatively heavy MSW material drops down a chute onto a second conveyer. A separation screen receives the relatively light MSW recyclable materials from the air separator and separates the relatively flat paper and cardboard from the plastic and metal containers.
