Direct and indirect methods for measurement of food waste
| Name of the method | Description of the method |
|---|---|
| Direct methods | |
| Direct measurement (weighing or volumetric assessment) | It consists of use of measuring device to determine the mass of food waste samples or fractions of the whole food waste, conducted directly or on the basis of their volume. It includes measurement of separately collected food waste |
| Scanning/Counting | Assessment of the number of items that make up food waste, and useof the result to determine the mass |
| Waste composition analysis | Physical separation of food waste fraction from other fractions in order to determine the mass of the fraction sorted out |
| Diaries | An individual or a group of individuals keeps a record or log of food waste information on a regular basis |
| Surveys and interviews | It consists of the development of the surveys (questionnaires) in the range of the quantitative and qualitative data and gaining appropriate information from the respondents |
| Indirect methods | |
| Mass balance | Calculation of the amount of food waste based on the mass (weight) of ‘inputs’ and ‘outputs’ of food into and out of the measured system, considering processing and consumption of food within the system |
| Coefficients | Use of previously established food waste coefficients or percentages being representative for a food industry sector or for individual business operator. Such coefficients or percentage shall be established through sampling, data provided by food business operator or by other methods. |
