1 Fighting Food Waste and Saving Energy by improving Household Refrigeration VHK for the European Commission, DG ENER, Unit C.3 Published February 2017 The information and views set out in this presentation are those of the author(s) and do not necessarily reflect the official opinion of the European Commission

2 Content VHK in short Introduction Aim of study EU food system EU impacts Refrigerators and food waste Concluding remarks

3 VHK in short Founded in 1984 Leading technical consultant Ecodesign & Energy Labelling Working on Methodology development, Impact Assessments and Monitoring of standards for wide scope of products (ErP) Headquarters in Delft, NL; facility in Brussels

4 Introduction Food waste problem Integrate in existing policies EU policy framework Ecodesign & Energy Labelling VHK preparatory study identified opportunities Complementary study: optimal food storage conditions in refrigeration appliances

5 Aim of study 1. Create complete and consistent picture of EU s food system 2. Explore the link between food waste and household refrigeration appliances Optimizing storage conditions

6 EU food system Extensive amount of food waste studies E.g. FUSIONS (EU), WRAP (UK), FAO, etc. Issue with quantitative assessment No internationally agreed definition No unique measuring method What we did: Explore the coherence between quantitative data Closed mass-based accounting system

17 Prolonging the preservation period AVERAGE Fresh juice 4 4 Bread & pastry 4 20 Dairy (cheese) & Eggs Meat & Fish NOW days BETTER extra days BEST extra days Fruit Vegetables Minimum days without spoilage Note that BEST only applies to optimisation for certain types of fruit (apples, pears) and vegetables (onions, carrots), which already have a long shelf-life. In that sense BETTER is probably the more realistic option. In Dairy, the storage conditions for cheese can be considerably improved; for fresh milk and other dairy products the current conditions are optimal (NOW=BEST).

19 Food-optimised refrigerator design Factor 2 oversized Significant technical (30-40%) and economic (18-20%) saving potential New energy saving possibilities e.g. cascading and re-use waste cold A saving of 1-2% on end-use food waste compensates 20% higher energy use fridge

20 Concluding remarks Improved fridge design, expanding temperature compartments Increase average shelf life with factor of 2 to 3 Further research recommended, e.g. field study Multi-door correction factor for fridges in Ecodesign & Energy Labelling policy Harmonisation of setting use-by dates ** *** (-12 C) till (-18 C) till

Flows <0.5 Mt are not shown and thus rounded figures will not always match. Pre-harvest & pre-slaughter waste is excluded. Flows of softdrinks (ca. 50), bottled mineral waters (56) and some non-perishable small flows ( cacao 5, sauce & spices 4, salt 3, sweeteners 2.5, coffee 2.2, spirits 1.4, babyfood 1.1, vinegar, tea 1 0.4, etc. ) are only listed at end-use. Vegetables includes pulses (beans, peas, etc.). Oilcrops includes treenuts. Fish includes ustaceans cr and molusks. Output used for seeds or own use is in brackets. Consumption off tapwater is not included in the end-use. Irrigation water (62 Gt), other farm wate r use (2 Gt), fertiliser (19 Mt), manure (12Mt), pesticide(0.2 ), energy (283 Mtoe) are also not ncluded i here Mt.
