The production of electric and Classifying Equipment is one of the fastest growing areas. This development has resulted in an increase of waste electric and classifying equipment. In view of the environmental problems involved in the management of WEEE, many counties and organizations have drafted national legislation to improve the reuse, recycling and other forms of recovery of such wastes so as to reduce disposal. Recycling of WEEE is an important subject not only from the point of waste treatment but also from the recovery of valuable materials.

WEEE is diverse and complex, in terms of materials and components makeup as well as the original equipment's manufacturing processes. Characterization of this waste stream is of paramount importance for developing a cost-effective and environmentally friendly recycling system. The physical and particle properties of WEEE are presented. Selective disassembly, targeting on singling out hazardous and/or valuable components, is an indispensable process in the practice of recycling of WEEE. Disassembly process planning and innovation of disassembly facilities are most active research areas. Mechanical/physical processing, based on the characterization of WEEE, provides an alternative means of recovering valuable materials. Mechanical processes, such as screening, shape separation, magnetic separation, Eddy current separation, electrostatic separation, and jigging have been widely utilized in recycling industry. However, recycling of WEEE is only beginning.

Consumer classifying equipment (brown goods), such as television sets, video recorders, are most common. It is very costly to perform manual dismantling of those products, due to the fact that brown goods contain very low-grade precious metals and copper. It is expected that a mechanical recycling process will be developed for the upgrading of low metal content scraps.

So what can be done? If your old units still work but have merely been eclipsed by newer models, then by all means donate them to a needy cause that will either put them to good use or resell them to help fund their programs. You’ll earn a tax deduction for a charitable donation and, by keeping the equipment alive, prevent the manufacture of new units and thus, if ever so slightly, reduce the footprint of your operations.

Several methods based on pyrometallurgy and Hydrometallurgy Equipment are currently used for the recovery of metals from waste PCBs. Pyrometallurgical processes require heating the waste EEE at high temperatures to recover valuable metals. These treatments lead to the production of hazardous gases that must be removed from the air with flue gas cleaning systems. These processes are energy intensive and high-cost and require high-grade (rich in copper and precious metals) feeds.
