Waste Reduction ROI with waste reduction project investment of 34,000 $: a worked example

This worked example runs the waste reduction roi numbers for a tougher week than the baseline: waste reduction project investment of 34,000 $ instead of the typical 68,000 $. Estimate simple payback for waste reduction roi from investment, annual savings, and annual support cost.

The inputs for this scenario

  • Waste reduction project investment: 34,000 $ (the input this scenario stresses; the baseline uses 68,000)
  • Annual avoided waste cost: 24,500 $ / yr (held at the documented default)
  • Annual program support cost: 3,500 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual savings = annual avoided waste cost - annual program support cost.
  • Waste Reduction ROI works out to 1.62 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual environmental savings works out to 21,000 $ / yr at these inputs.
  • Waste reduction project investment works out to 34,000 $ at these inputs.
  • Five-year net value works out to 71,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where waste reduction project investment sits at 68,000 $ and the headline result is 3.24 yr, this scenario comes in 50% below the baseline at 1.62 yr.
  • Use it when evaluating a waste-stream reduction, segregation, or recovery project before committing capital. 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.
