Battery Recycling & Materials Recovery worked example

Material Assay Workload at 35% preparation and retest allowance: a worked example

This scenario runs the material assay workload calculation on the strong side: 35% preparation and retest allowance, with every other input held at its documented default. a battery recycler needs to schedule assay resources for incoming lots, black mass shipments, process trials, or recovered metal sales

The inputs for this scenario

  • Battery material assay samples: 96 samples (unchanged)
  • Assay testing rate: 8 samples / hr (unchanged)
  • Preparation and retest allowance: 35 % (raised for this scenario; the documented default is 30)

Working through the calculation

  • Applying the documented formula (Base assay testing time = assay sample count รท assay testing rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 16.2 hr for required assay workload, the number this scenario is built around.
  • At this operating point the engine returns 12 hr for base assay testing time.
  • At this operating point the engine returns 35 % for preparation and retest allowance.
  • At this operating point the engine returns 8 samples / hr for assay testing rate.

How this compares with the baseline

  • Against the tool's baseline example, where preparation and retest allowance sits at 30% and the headline result is 15.6 hr, this scenario comes in 3.85% above the baseline at 16.2 hr.
  • Use it when staffing the assay bench, quoting lot-release turnaround, or sizing lab capacity against incoming sample volume. 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

  • Required assay workload: 16.2 hr (headline result)
  • Base assay testing time: 12 hr
  • Preparation and retest allowance: 35 %
  • Assay testing rate: 8 samples / hr
