Mass production and mass consumption generate massive quantities of industrial scrap as well as post consumer wastes. This may give rise to serious environmental trouble due to harmful metals and the exhaustion of resources by the loss of valuable metals in the near future. Resources supply and environmental production are increasingly becoming matters of global concern. Establishment of social systems for waste zero emission and promotion of re-use as well as of technology for improving recycling efficiencies are needed for sustainable development. The new technology is expected to reduce the energy consumption and environmental burden caused by the treatment of by-product. There has recently been a growing interest in the separation of mixture based on the segregation that takes place in handling in a mixture containing solid particles of different properties. In this article, solid-solid separation technology using segregation of solid mixture in horizontally circular bed is briefly discussed.
