Overall food waste tonnage: 35,382
Food waste in tonnes as a % of food produced in tonnes: 3.50%

Food waste amount by destination (tonnes):

  • Anaerobic Digestion: 18,615
  • Land Application: 8,970
  • Composting: 7,727
  • Controlled Combustion: 71

Other destinations (tonnes):

  • Animal Feed: 10,656
  • Biochemical: 4,438
  • Redistribution for human consumption: 420

1. Base FLW accounting and reporting on the principles of relevance, completeness, consistency, transparency, and accuracy

  • Relevance: Data is being used to help set group, divisional & site food waste reduction targets for the following year.
  • Completeness: All direct UK & Ireland manufacturing locations are included, as of Jan 2019 (all sites sold by the business during 2018 are not included in the data).
  • Consistency: Use same methodology each year.
  • Transparency: Weekly volume & weight data from all sites collected centrally by our waste management company. These figures used to accurately calculate annual volumes. Sludge & drain waste weight figures have been assumed to contain 10% solids, based on previous experience. This will be verified by testing in 2019.
  • Accuracy: Varies depending on destination; ongoing work to reduce uncertainties. Some asumptions have been made regarding actual solids contant.

2. Account for and report the physical amount of FLW expressed as weight
Food waste reported in tonnes

3. Define and report on the scope of the FLW inventory

  • Timeframe: 12 months; January 1, 2018 – December 31, 2018
  • Material type: Food and associated inedible parts. Excluding inedible parts from primary production (blood, feathers, etc), which is all further processed and used, therefore not food waste).
  • Destination: While multiple destinations fall under the definition of “food waste” for 2SFG, food waste in this inventory only goes to; Anaerobic Digestion, Composting, Controlled Combustion & Land Application.
  • Boundary:
    • Food category: All food (GSFA 1.0 TO 16.0)
    • Lifecycle stage: Manufacturing (ISIC Class 1010 to 1080) & transport (ISIC Class 4923)
    • Geography: UK & Ireland (UN Code 826 & 372)
    • Organization: All UK & Ireland processing units
  • Related issues: Packaging weight is excluded.

4. Describe the quantification method(s) used. If existing studies or data are used, identify the source and scope: Data taken from weight records at despatch from sites. All data collected by waste processor & entered onto spreadsheet.
Quantification methods include: direct weighing, records and waste composition analysis.

5. If sampling and scaling of data are undertaken, describe the approach and calculation used, as well as the period of time over which sample data are collected (including starting and ending dates)

6. Provide a qualitative description and/or quantitative assessment of the uncertainty around FLW inventory results
Sources of uncertainty include estimates made about the solids content of drain waste, wash water waste, etc. Calculations are based on a 10% solids content. Some uncertainty on the exact breakdown of destinations for food waste.

7. If assurance of the FLW inventory is undertaken (which may include peer review, verification, validation, quality assurance, quality control, and audit), create an assurance statement
Calculations have been based solely on the data supplied by the waste processor. Validation of the accuracy of data collection and waste stream confirmation will be carried out in 2019.

8. If tracking the amount of FLW and/or setting an FLW reduction target, select a base year, identify the scope of the target, and recalculate the base year FLW inventory when necessary

  • Base year is 2017
  • Food waste reduction target of 50% by 2030
