Quantification of food waste per product group along the food supply chain in the European Union: a mass flow analysis
Van Holsteijn en Kemna, European Commission-Joint Research Centre
published in Elsevier Journal of Resources, Conservation and Recycling, Volume 149, October 2019, Pages 479-488
A systematized food waste accounting at macro scale level was developed for Europe. The accounting follows Mass Flow Analysis concepts, ensuring closed mass balance. Disaggregated values per food supply chain stages and per food groups are presented. Hotspots and food groups with higher share of food waste were identified. The stage contributing the most to food waste varies depending on the food group.

Minimizing food waste by improving storage conditions in household refrigeration
F. van Holsteijn, R. Kemna
published in Elsevier Journal of Resources, Conservation and Recycling, Volume 128, January 2018, Pages 25-31
Current household food storage conditions are suboptimal for many fresh products. Multiple temperature compartments in refrigerators can extend the shelf life of food. Optimized refrigerator design can be a useful tool to reduce food waste. Existing legislation on energy labelling of refrigeration appliances requires revision.
Rethinking the Function of the Fridge
F. van Holsteijn
published in Renewable Matter magazine 16, May-June 2017 (available with permission of ReteAmbiente s.r.l.)
Every year European households bin 84 million tonnes of food. Better food preservation can help cut waste and reduce at the same time energy consumption and envirionmental impact. Smart fridges can help exchange information with consumers on the best way to preserve food.
