The proper disposal of electronic waste and electrical components is currently a major interest of many researchers because of the fact that these electronics not only generate the landfill waste, but also release heavy and toxic metals to the local environment and farm lands. This study analyzes the possible eliminations of waste products by recovering the metals, and thus reducing the effects on the environment and reserving the metals for future generations. The experimental studies were performed on the recycled electronic wires, such as copper, aluminum, soldering materials and lead. An electrical induction furnace is used for melting/burning the waste to recover the metals from the electronic devices and cable waste. A perforated basket was designed and manufactured for feeding the E-waste and heat application (melting) at high temperatures. All the metals were heated to their respective melting points and recovered by centrifugal forces. Experiments carried out with insulation materials on the electrical wires and over 95% recovery rates were achieved at the high speed rotations of the perforated basket.
