Recycling automatic-sorting

Manual Component Separation The manual separation of solid-waste components can be accomplished at the source where solid wastes are generated, at a transfer station, at a centralized processing station, or at the disposal site. Manual sorting at the source of generation is the most positive way to achieve the recoveiy and reuse of materials. The number and types of components salvaged or sorted (e.g., cardboard and high-quality paper, metals, and wood) depend on the location, the opportunities for recycling, and the resale market. There has been an evolution in the solid waste indus-tiy to combine manual and automatic separation techniques to reduce overall costs and produce a cleaner product, especially for recyclable materials. 

Similarly, the increasing efforts in recent years to recycle used plastics and plastics waste involve a number of analytical problems. Plastics waste containing a mixture of plastics can often be sorted using simple methods to identify the different plastics. It is stUl difficult, but possible, however, to automatically identify the different plastics and to sort them at the same... 

Some of the crush mgand sorting is now done automatically in "reverse vending machines" designed to collect bottles for recycling.
