Wood & Paper Manufacturing worked example

Fiber Recovery Rate at 99% target fiber recovery rate: a worked example

This scenario runs the fiber recovery rate calculation on the strong side: 99% target fiber recovery rate, with every other input held at its documented default. Use it when fiber recovery rate in wood and paper manufacturing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Recovered Usable Fiber (Reclaimed): 8 count (unchanged)
  • Total Fiber Input to Recovery Loop: 250 count (unchanged)
  • Target Fiber Recovery Rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Fiber recovery rate = fiber recovery rate count ÷ total fiber recovery rate population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for fiber recovery rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for fiber recovery rate gap to target.
  • At this operating point the engine returns 8 count for fiber recovery rate count.
  • At this operating point the engine returns 250 count for total fiber recovery rate population.

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. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Fiber recovery rate: 3.2 % (headline result)
  • Fiber recovery rate gap to target: 95.8 points
  • Fiber recovery rate count: 8 count
  • Total fiber recovery rate population: 250 count
