Black Mass Recovery Yield at 23% target black mass yield: a worked example

This worked example runs the black mass recovery yield numbers for a tougher week than the baseline: 23% target black mass yield instead of the typical 32%. Calculate black mass yield from recovered black mass weight, incoming battery feed mass, and the target recovery yield for a recycling run.

The inputs for this scenario

  • Recovered black mass weight: 2,850 kg (held at the documented default)
  • Incoming battery feed mass: 9,000 kg (held at the documented default)
  • Target black mass yield: 23 % (the input this scenario stresses; the baseline uses 32)

Working through the calculation

  • The calculation starts from the formula this tool documents: Black mass recovery yield = recovered black mass weight รท incoming battery feed mass.
  • Black mass recovery yield works out to 31.67 % black mass yield at these inputs, and this is the headline figure for the scenario.
  • Yield gap to target works out to -8.67 points at these inputs.
  • Recovered black mass works out to 2,850 kg at these inputs.
  • Incoming battery feed works out to 9,000 kg at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target black mass yield sits at 32% and the headline result is 31.67 % black mass yield, this scenario lands almost exactly on the baseline at 31.67 % black mass yield.
  • Use it per batch, shift, or feedstock type when monitoring shredding and separation performance or qualifying a new feed stream. 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

  • Black mass recovery yield: 31.67 % black mass yield (headline result)
  • Yield gap to target: -8.67 points
  • Recovered black mass: 2,850 kg
  • Incoming battery feed: 9,000 kg
