Recycled Bio-Resin Content at 17% target recycled bio-resin content: a worked example

Push target recycled bio-resin content up to 17% and the picture changes. This example computes every intermediate figure at that operating point. a compounder, film converter, or molder needs to verify recycled bio-resin or regrind percentage in a formulation

The inputs for this scenario

  • Recycled bio-resin or regrind weight: 180 kg or lb (unchanged)
  • Total biomaterial blend weight: 1,200 kg or lb (unchanged)
  • Target recycled bio-resin content: 17 % (raised for this scenario; the documented default is 15)

Working through the calculation

  • Applying the documented formula (Recycled bio-resin content = recycled bio-resin or regrind weight ÷ total biomaterial blend weight × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 15 % recycled bio-resin for recycled bio-resin content, the number this scenario is built around.
  • At this operating point the engine returns 2 points for recycled content gap to target.
  • At this operating point the engine returns 180 kg or lb for recycled bio-resin or regrind weight.
  • At this operating point the engine returns 1,200 kg or lb for total biomaterial blend weight.

How this compares with the baseline

  • Against the tool's baseline example, where target recycled bio-resin content sits at 15% and the headline result is 15 % recycled bio-resin, this scenario lands almost exactly on the baseline at 15 % recycled bio-resin.
  • It divides recycled or regrind weight by total blend weight and multiplies by 100 to give recycled content percent, then subtracts your target to show the gap in percentage points. 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

  • Recycled bio-resin content: 15 % recycled bio-resin (headline result)
  • Recycled content gap to target: 2 points
  • Recycled bio-resin or regrind weight: 180 kg or lb
  • Total biomaterial blend weight: 1,200 kg or lb
