Description
Return denominator = totalWaste-excluded and diversionFraction = diverted/denominator.
Environmental monitoring coverage depends on what counts in the denominator. Time, effort, area, sampled volume and exposure weights describe different support measures; excluding missing or ineligible portions changes the question answered by a fraction.
Return denominator = totalWaste-excluded and diversionFraction = diverted/denominator.
When to use this tool
Use Recycling Diversion Excluded Stream Basis when checking a monitoring or sampling share with an explicit inclusion and overlap convention.
How to use the tool and how it works
- Enter diverted, totalWaste, excluded. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read denominator, diversionFraction. Use the output convention below.
Require nonnegative excluded and totalWaste > excluded, with diverted between zero and totalWaste-excluded. Return denominator = totalWaste-excluded and diversionFraction = diverted/denominator. Use the same waste amount unit for all three quantities.1

| diverted | Diverted | Required. Finite number; minimum 0. |
| totalWaste | Total Waste | Required. Finite number. |
| excluded | Excluded | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| denominator | Denominator | Required. Finite number. |
| diversionFraction | Diversion Fraction | Required. Finite number. |

}Limitations and assumptions
- The excluded stream changes the reporting basis. This arithmetic does not choose a regulatory diversion definition or determine whether a stream is recyclable or properly credited.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review source intervals and sampling design, and compute overlaps from actual records when an aggregate deduction cannot be justified.
