Waste Reduction ROI with waste reduction project investment of 170,000 $: a worked example

This scenario runs the waste reduction roi calculation on the strong side: waste reduction project investment of 170,000 $, with every other input held at its documented default. a plant, EHS, or sustainability manager needs to screen waste reduction roi

The inputs for this scenario

  • Waste reduction project investment: 170,000 $ (raised for this scenario; the documented default is 68,000)
  • Annual avoided waste cost: 24,500 $ / yr (unchanged)
  • Annual program support cost: 3,500 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual savings = annual avoided waste cost - annual program support cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.1 yr for waste reduction roi, the number this scenario is built around.
  • At this operating point the engine returns 21,000 $ / yr for net annual environmental savings.
  • At this operating point the engine returns 170,000 $ for waste reduction project investment.
  • At this operating point the engine returns -65,000 $ for five-year net value.

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 150% above the baseline at 8.1 yr.
  • Use it when evaluating a waste-stream reduction, segregation, or recovery project before committing capital. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
