Value structure
Dimensions and units
- Unit
- % of food waste — source-defined reporting unit
- Reporting basis
- Reporting period
Unit meaning: Values use % of food waste under the disclosed TNFD sector-guidance method, reporting period and boundary.

- Percentage
Formula
(food waste repurposed into by-products or co-products / total food waste) × 100Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. FA.C23.0 explicitly identifies an outcome metric measuring the percentage of food waste repurposed into by-products or co-products. It is a standalone percentage result rather than an input or calculation parameter, and no shortlisted existing metric has the same construct, denominator and value shape.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
R | Food waste repurposed | Quantity of food waste repurposed into by-products or co-products within the reported boundary during the reporting period. | mass |
W | Total food waste | Total quantity of food waste within the same reported boundary and reporting period. | mass |

Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

- Definition of food waste used, including included and excluded materials.
- Definition and eligibility criteria used for repurposing into by-products or co-products.
- Mass-quantification method, data sources, estimation methods and any conversion factors.
- Numerator mass of food waste repurposed and denominator mass of total food waste.
- Organizational boundary, facilities, activities and value-chain stages included or excluded.
- Reporting period and treatment of any acquisitions, disposals, seasonal operations or incomplete data.
Record-specific limitations
- The metric does not indicate the environmental quality, end use, market value or ultimate fate of repurposed by-products or co-products.
- Comparability depends on consistent definitions of food waste, repurposing, and the organizational and value-chain boundary.
- The reported percentage may be affected by estimation methods where food-waste quantities are not directly measured.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
