Quantification of Food-Waste across EU-28 Results of Model Calculations
Fusions Regional Platform Meeting – Budapest, June 3, 2015

2. Background
Study for the “Science and Technology Options Assessment (STOA)” Board of the European Parliament Title of the whole study: Technology options for feeding 10 billion people Title of the Study performed by ITAS Options for cutting food waste (Study finished and published in 2013) Authors: Carmen Priefer, Juliane Jörissen, Klaus-Rainer Bräutigam
Dipl.-Phys. Klaus-Rainer Bräutigam - ITAS

3. Aim of the Study
To summarise existing research on food waste generation in Europe
To give insight into the reliability of the available data on the basis of own model calculation (amount of food waste for the different stages of the food-supply chain as well as for different food-types for all EU- 27 countries)
To analyse political and regulatory framework conditions
To compile and evaluate prevention measures, already existing or currently under discussion
To elaborate options for action

4. Data on Food-Waste – the BIOIS-Study
All stages of the food chain except agriculture (manufacturing, wholesail/retail, food service and catering, households)
All EU-27 countries
No differentiation between food groups
As far as possible on the basis of data from national studies
Dipl.-Phys. Klaus-Rainer Bräutigam - ITAS

5. BIOIS-Study – Manufacturing Sector
National data for the manufacturing sector are only available for UK. For all other countries BIOIS used EUROSTAT data
Examples:
UK: 2,591 Mio WRAP study compared to 5,143 Mio EUROSTAT
NL: 6,412 Mio EUROSTAT compared to 1,500 Mio due to new estimations
Unexplainable high values also for Poland, Estonia, Hungary and Belgium
BIOIS states: most discrepancies are likely due to a lack of standardization in definitions and allocation of data, rather than exceptional differences between Member States
Dipl.-Phys. Klaus-Rainer Bräutigam - ITAS

6. BIOIS-Study – Household Sector
Country specific data for:
Denmark, France, UK, Austria. Ireland, Netherlands, Estonia and Sweden
EUROSTAT data for:
Italy, Luxembourg, Poland, Belgium and Germany
„Minimum-scenario“ data for
Greece, Romania, Portugal, Spain, Malta, Lithuania, Hungary, Cyprus, Slovenia, Latvia, Finland, Czech-Republic, Slovakia and Bulgaria

8. Waste Percentages for different Food Groups at different Stages of the Food Supply Chain (Gustavsson et al., 2013)
Dipl.-Phys. Klaus-Rainer Bräutigam - ITAS

9. Evaluation of Model Results
Advantages
Based on a regularly availabe data base (Food Balance sheets)
Data for all EU-28 countries
Differentiation between food groups
Calculations are based on a „correct“ mass flow balance
Enables to identify „hotspots“ (e.g. country, type of food, stage of the food chain), which are most reponsible for the arising of food waste
Dipl.-Phys. Klaus-Rainer Bräutigam - ITAS

10. Evaluation of Model Results
Disadvantages
Waste rates for the different stages of the food chain were taken from the study of Gustavsson et al., and no differentiation between countries is made
Reliability of data from FAO (data are based on reports from individual countries)

15. Share of Different Food Types on total Food Waste in Households for 2011

92 kg per capita
Dipl.-Phys. Klaus-Rainer Bräutigam - ITAS

16. Share of Different Food Types on total Food Waste in Households for 2011
105 kg per capita
113 kg per capita
Dipl.-Phys. Klaus-Rainer Bräutigam - ITAS

17. Summary Up to now there is a lack of reliable data
For total amount of food waste at the different stages of the food chain
For the share of different food groups to total amount of food waste
This fact makes it difficult to develop and implement measures to reduce food waste and to evaluate these measures
Therefore methods used by the Member States for the collection and calculation of data on food waste generation should be standardised
In addition separate collection of food waste generated at all stages of the food supply chain, whether voluntarily or mandatory, might help to improve the data basis
Dipl.-Phys. Klaus-Rainer Bräutigam - ITAS

18. Summary
Model calculations on the basis of the data of the FAO (FBS-sheets) can serve as a basis for comparison with data collected in other ways.
Data from model calculations are available for all EU-28 countries, will be updated regularly and are available - in a consistent manner - for all stages of the food chain and for different food groups
However, so far, waste rates applied within the model calculations, do not differentiate between countries.
In order to overcome this obstacle work has to be done to develop country specific waste rates for the different stages of the food chain and for different food-types.
