Minimizing food waste by improving storage conditions in household refrigeration Link opens a new window

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.
