Scrap Recovery Value at 81% recovery yield after reclaim: a worked example in rare earth magnet & motor materials

Push recovery yield after reclaim up to 81% and the picture changes. This example computes every intermediate figure at that operating point. Use it to value a magnet scrap reclaim stream when deciding between disposal and rare earth recovery.

The inputs for this scenario

  • Magnet Scrap Mass Recovered: 800 kg (unchanged)
  • Reclaimed RE Value per Kilogram: 45 $/kg (unchanged)
  • Recovery Yield after Reclaim: 81 % (raised for this scenario; the documented default is 70)
  • Reclaim Processing Overhead: 2,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Net recovery value = scrap mass x value per kg x recovery yield% + processing overhead) to the inputs above produces each figure below.
  • At this operating point the engine returns 31,160 $ for total scrap recovery value cost, the number this scenario is built around.
  • At this operating point the engine returns 38.95 $ / piece for scrap recovery value cost per unit.
  • At this operating point the engine returns 29,160 $ for variable scrap recovery value cost.
  • At this operating point the engine returns 2,000 $ for fixed scrap recovery value adder.

How this compares with the baseline

  • Against the tool's baseline example, where recovery yield after reclaim sits at 70% and the headline result is 27,200 $, this scenario comes in 14.56% above the baseline at 31,160 $.
  • It calculates net recovery value from a mass of magnet scrap, its per-kilogram reclaim value, the fraction actually recovered, plus the overhead of processing it. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
