Bio-Resin Usage with bio-resin throughput rate of 120 kg/hr or lb/hr: a worked example

This worked example runs the bio-resin usage numbers for a tougher week than the baseline: bio-resin throughput rate of 120 kg/hr or lb/hr instead of the typical 240 kg/hr or lb/hr. Estimate bio-resin, compound, filler, or additive consumption and run cost from use rate, runtime, and cost per unit for extrusion, molding, or packaging runs.

The inputs for this scenario

  • Bio-resin throughput rate: 120 kg/hr or lb/hr (the input this scenario stresses; the baseline uses 240)
  • Planned production run time: 10 hr (held at the documented default)
  • Bio-resin price per unit mass: 3.65 $ / kg or lb (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Bio-resin consumed = bio-resin use rate × planned processing runtime.
  • Bio-resin consumed works out to 1,200 kg or lb at these inputs, and this is the headline figure for the scenario.
  • Bio-resin run cost works out to 4,380 $ at these inputs.
  • Planned processing runtime works out to 10 hr at these inputs.
  • Bio-resin cost per unit works out to 3.65 $ / kg or lb at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where bio-resin throughput rate sits at 240 kg/hr or lb/hr and the headline result is 2,400 kg or lb, this scenario comes in 50% below the baseline at 1,200 kg or lb.
  • Use it when planning a production run, reserving inventory, or pricing the material portion of a quote for a bioplastic part or package. 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.
