On June 28 via July 1 of 2006, a NATO complicated study Workshop was once held in Kyiv, Ukraine. This workshop introduced the head researchers in Fuzzy GIS jointly, either from NATO nations in addition to associate nations. The workshop desirous about how uncertainty and fuzziness should be higher modelled and applied in Geographic details technological know-how to assist choice makers make extra educated offerings, in particular as they pertain to environmental safeguard and defense.

A new system is necessary for this and greater development of recycling technologies for minor rare metals. The above has considered impacts on environment from a resource perspective. Environmental problems will continue to be important but natural resource security will also become as important. Creating a zero-waste society aims to combat both of these issues and promotes sustainable development. Furthermore, natural resources depend on the land in which they are found and so can easily become involved in politics.

It was slow separation speed at early stage of development. Now this technique has become one of major process in physical separation. 9. Key point of this process is what characters are analyzed by using various sensors like color, shape, weight and chemical composition. Almost every sensing techniques like IR, XRD and XRF are available for the characterization of target materials. High quality separation can be achieved by this technique especially for waste plastics. Even plastics contained brominated flame retardants can be separated from waste plastics.

Sorting techniques have been rapidly developed in recent. First development of this technique is old as other physical separation processes. It was slow separation speed at early stage of development. Now this technique has become one of major process in physical separation. 9. Key point of this process is what characters are analyzed by using various sensors like color, shape, weight and chemical composition. Almost every sensing techniques like IR, XRD and XRF are available for the characterization of target materials.
