Wood & Paper Manufacturing worked example

Fiber Recovery Rate at 68% target fiber recovery rate: a worked example

This worked example runs the fiber recovery rate numbers for a tougher week than the baseline: 68% target fiber recovery rate instead of the typical 95%. Estimate fiber recovery rate for wood and paper manufacturing using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Recovered Usable Fiber (Reclaimed): 8 count (held at the documented default)
  • Total Fiber Input to Recovery Loop: 250 count (held at the documented default)
  • Target Fiber Recovery Rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fiber recovery rate = fiber recovery rate count ÷ total fiber recovery rate population × 100.
  • Fiber recovery rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Fiber recovery rate gap to target works out to 64.8 points at these inputs.
  • Fiber recovery rate count works out to 8 count at these inputs.
  • Total fiber recovery rate population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target fiber recovery rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it when auditing a repulper, reject screen, or save-all, or when a furnish cost spike points to fiber leaving the loop. 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

  • Fiber recovery rate: 3.2 % (headline result)
  • Fiber recovery rate gap to target: 64.8 points
  • Fiber recovery rate count: 8 count
  • Total fiber recovery rate population: 250 count
