Elastomer Scrap Cost at 58% non-recoverable share: a worked example

This worked example runs the elastomer scrap cost numbers for a tougher week than the baseline: 58% non-recoverable share instead of the typical 80%. Estimate the cost of scrapped elastomer, accounting for invested material value, non-recoverable share and disposal of cured waste.

The inputs for this scenario

  • Scrap elastomer weight: 120 kg (held at the documented default)
  • Loaded compound cost: 5.2 $/kg (held at the documented default)
  • Non-recoverable (non-regrind) share: 58 % (the input this scenario stresses; the baseline uses 80)
  • Disposal and handling charge: 150 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Scrap cost = scrap kg x loaded cost/kg x non-recoverable% + disposal charge.
  • Total elastomer scrap cost works out to 512 $ at these inputs, and this is the headline figure for the scenario.
  • Elastomer scrap cost per unit works out to 4.27 $ / piece at these inputs.
  • Variable elastomer scrap cost works out to 362 $ at these inputs.
  • Fixed elastomer scrap cost adder works out to 150 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where non-recoverable share sits at 80% and the headline result is 649 $, this scenario comes in 21.15% below the baseline at 512 $.
  • Use it when building a quote's scrap allowance, justifying a yield-improvement project, or comparing scrap cost across compounds or presses. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total elastomer scrap cost: 512 $ (headline result)
  • Elastomer scrap cost per unit: 4.27 $ / piece
  • Variable elastomer scrap cost: 362 $
  • Fixed elastomer scrap cost adder: 150 $
