Roll Scrap Cost at 92% unrecoverable share: a worked example in nonwoven materials & technical textiles

Push unrecoverable share up to 92% and the picture changes. This example computes every intermediate figure at that operating point. A converting supervisor quantifies scrap exposure on a slitting and winding run to judge whether trim losses justify a process change.

The inputs for this scenario

  • Scrapped roll length: 1,200 m (unchanged)
  • Material value per scrapped meter: 0.85 $/m (unchanged)
  • Unrecoverable (non-reclaimable) share: 92 % (raised for this scenario; the documented default is 80)
  • Waste handling and disposal fee: 120 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Scrap cost = scrapped length x value per meter x unrecoverable share% + handling fee) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,058 $ for total roll scrap cost, the number this scenario is built around.
  • At this operating point the engine returns 0.88 $ / piece for roll scrap cost per unit.
  • At this operating point the engine returns 938 $ for variable roll scrap cost.
  • At this operating point the engine returns 120 $ for fixed roll scrap cost adder.

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 13.08% above the baseline at 1,058 $.
  • It computes the total cost of a scrapped roll by valuing only the unrecoverable portion of the material and adding the waste handling fee. 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.

Results at a glance

  • Total roll scrap cost: 1,058 $ (headline result)
