Mr. Tom Horton Afth, Id1h. Project 939-02.22 <br /> January 25, 1990 <br /> Page 6 <br /> Typical Recycling Activities at Landfills <br /> Organized recycling activities occur at most existing landfills. These activities <br /> range from salvaging at the landfill face to mechanized materials sorting and <br /> recovery. The following numbered sections describe many of the current <br /> materials recovery processes. <br /> 1. Sorting at the Landfill Face <br /> Sorting at the landfill face is typically focused on the larger, more <br /> valuable materials. Commonly salvaged materials include: <br /> • Ferrous metals <br /> • Aluminum <br /> • Wood <br /> • Corrugated cardboard <br /> 2.. Sorting on a Slab <br /> To improve recovery effectiveness, concentrated commercial loads <br /> and public loads are tipped onto a concrete slab. The refuse is <br /> then spread in a thin layer over the slab, making the recyclable <br /> materials easier to identify and manually recover. <br /> 3. Conveyor Picking <br /> Spreading and sorting recyclable materials on a slab is sometimes <br /> enhanced by including a portable conveyor/sorting station. The <br /> larger materials are removed while the refuse is on the slab; the <br /> material is then dumped into a hopper, which feeds the conveyer <br /> belt. Workers are stationed along the belt to pick out the following <br /> select materials: <br /> • Glass <br /> • Cans (aluminum and ferrous) <br /> • Wood <br /> • Newspaper <br /> • Corrugated <br /> • Plastic <br />
