Due to the sharp rise in metal prices in recent years and from the perspective of resource security, there is a growing need for the recycling of valuable resources from solid waste.

A low-environmental-load type valuables recycling process can be proposed, in which, after various types of pulverization are conducted as preprocessing, a number of separation methods are combined, based on specific weight, electrical and magnetic properties, wettability, shape, color, X-ray properties, and physical/physiochemical properties according to target.

Furthermore, by adding separation technology that uses chemical properties, it is also possible to propose a process for recycling valuables from within wastewater.

Selection of separation methods that use the solid characteristics allows special valuables recycling processes, such as dry-type and pharmaceutical free to be proposed.
