Roll Scrap Cost at 58% unrecoverable share: a worked example in nonwoven materials & technical textiles

Suppose unrecoverable share falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the value lost to edge trim, off-spec and threading scrap on a nonwoven roll line.

The inputs for this scenario

  • Scrapped roll length: 1,200 m (held at the documented default)
  • Material value per scrapped meter: 0.85 $/m (held at the documented default)
  • Unrecoverable (non-reclaimable) share: 58 % (the input this scenario stresses; the baseline uses 80)
  • Waste handling and disposal fee: 120 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Scrap cost = scrapped length x value per meter x unrecoverable share% + handling fee.
  • Total roll scrap cost works out to 712 $ at these inputs, and this is the headline figure for the scenario.
  • Roll scrap cost per unit works out to 0.59 $ / piece at these inputs.
  • Variable roll scrap cost works out to 592 $ at these inputs.
  • Fixed roll scrap cost adder works out to 120 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where unrecoverable share sits at 80% and the headline result is 936 $, this scenario comes in 23.97% below the baseline at 712 $.
  • It computes the total cost of a scrapped roll by valuing only the unrecoverable portion of the material and adding the waste handling fee. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
