Mobile buy-back units often pay for some materials and accept for free other materials. Processing And Storage Approaches Collected material is usually brought to a processing center. Here it is separated, processed, and stored until enough material has been collected to create a full load for transport to a market. Material usually must be processed to meet the specifications of buyers. The center must be designed to efficiently move the material from the tipping floor or drop-off point through the system to the storage area.
Many technologies are available for efficient processing, materials handling, and storage.
Collected glass can be dumped into the revetment compartment or removed by a small tractor. A barrier is often placed at the front of the revetment to ensure that injuries to employees or others do not occur from accidental spillage. Storage indoors of newspaper and other items can create problems for a poorly designed center, as there can be a constant struggle between space needed for processing and operations and space requirements for materials storage. What's more, storage problems can result when either the volume of recycled materials expected is significantly underestimated or the demand for materials already on hand is significantly overestimated. The amount of processing which will be necessary at the recycling center will depend to a large degree on how the material is collected.
