基于我国稀土的九大应用领域，对稀土产品废弃物进行辨识，并考虑稀土在不同领域的应用数量及变化趋势、废弃物中稀土元素的成份比例等因素对稀土产品废弃物的稀土资源回收价值进行探讨。稀土产品使用后所产生的含稀土废弃物主要有8类，其中废稀土磁材器件的稀土回收价值最高，废稀土抛光粉、废镍氢电池的回收价值较高，废FCC催化剂、废玻璃和陶瓷器件、废荧光粉的稀土回收价值一般，废汽车尾气净化器中的催化剂回收价值较低，废钢、铁、有色金属及合金的稀土回收价值很低。

The waste of rare earth products are first identified in this paper, then their rear earth recycling value is analyzed on the bases of quantity used in different areas, proportion of rare earth elements in the waste, etc. The waste of rare earth products are divided into 8 categories. Among them, waste rare earth magnet devices have the highest rare earth recovery value. Waste rare earth polishing powder and abandoned nickel-metal hydride batteries have higher recovery value. Spent FCC catalyst, glass and ceramic waste and waste phosphor have medium recovery value. Waste rare earth catalysts in automobile exhaust purifier have lower value. Iron, steel, non-ferrous metal and alloy scrap have the lowest recovery value.
