Most recycling techniques involve immersing the old CDs in a chemical solution, so as to separate the metal and plastic layers. FEU ’ s technology is unique in making use of the different electrical sensitivities of metals and plastics: An electric arc is set at different frequencies to separate the metals and plastics for recycling.
這項技術的特出之處在於，一般光碟回收時多以浸泡化學藥劑的方式，將光碟上的金屬層與塑膠層分離；遠東科大研發的技術，則是透過金屬與塑膠感電程度不同的原理，藉由電弧調節不同的通電頻率，分離金屬和塑膠後以方便回收。
