Roll Scrap Cost at 61% unrecoverable share: a worked example in specialty films, membranes & barrier materials

This worked example runs the roll scrap cost numbers for a tougher week than the baseline: 61% unrecoverable share instead of the typical 85%. Estimate the cost of scrapped film rolls including off-spec web, edge trim and core ends that cannot be reclaimed.

The inputs for this scenario

  • Scrapped film length: 3,000 linear meters (held at the documented default)
  • Loaded film value: 0.85 $/linear meter (held at the documented default)
  • Unrecoverable share: 61 % (the input this scenario stresses; the baseline uses 85)
  • Disposal and handling fee: 300 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total roll scrap = scrapped length x loaded value x unrecoverable share + disposal fee.
  • Total roll scrap cost works out to 1,856 $ at these inputs, and this is the headline figure for the scenario.
  • Roll scrap cost per unit works out to 0.62 $ / piece at these inputs.
  • Variable roll scrap cost works out to 1,556 $ at these inputs.
  • Fixed roll scrap cost adder works out to 300 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where unrecoverable share sits at 85% and the headline result is 2,468 $, this scenario comes in 24.8% below the baseline at 1,856 $.
  • Use it whenever you cost a scrap event, set yield targets, or evaluate whether reclaim or regrind capital is worth funding. 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 roll scrap cost: 1,856 $ (headline result)
