Q2. What is the main cause of food waste?
In a Norwegian study, 15% of the consumers said that packaging is an important cause for food waste, and 30% of the consumers stated that the too large packages are one important cause for food waste (Fredriksen et al., 2010).
Q3. What is the effect of price awareness on food waste?
Price awareness may influence the households to buy larger packages and save money per kilogram of food, which may result in more waste.
Q4. How much food waste is there in the UK, Norway and Sweden?
The wastage of avoidable food waste in average households in UK, Norway, and Sweden is about 4 kg/week (Quested and Johnson 2009; Fredriksen et al., 2010, SEPA, 2005).
Q5. What is the behavioural study from Cox and Downing (2007)?
The behavioural study from Cox and Downing (2007) reveals that environmentally conscious people are more likely to agree that packaging is a more important issue than food waste.
Q6. What are indirect aspects of food waste?
Variation in packaging sizes to meet various demands, or adding a lid to make the packaging re-sealable are examples of direct aspects.
Q7. What is the risk of social desirability bias with self-reporting?
There is also always the risk of social desirability bias with self-reporting; people respond/behave more to what they believe is socially desirable rather than to be truthful in surveys and questionnaires (Podsakoff et.al., 2003; Banjo and Val, 2011).
Q8. How many households liked the Tetra brik?
Four households in this study indicated that they liked the liquid board packaging with a screw lid and 22 indicated that they disliked it.
Q9. How many groups were created based on the answers given for the two price statements?
Two groups were created based on the answers given for the two price statements, one group with answers from 8 to 14 that noted price to be more important, and one group with answers from 2 to 7 that noted price to be less important.
Q10. How much of the food waste was related to the packaging design attributes?
In their sample, 20–25% of the food waste was related to the packaging design attributes, both the ones observed by consumers (easy to empty, too big packaging) and the one added by the authors (information attribute best-before-date).
Q11. What are the main reasons for food waste?
In the UK, between 75% and 90% of the consumers agreed that discarded packaging is a greater environmental issue than food that is wasted (Cox and Downing, 2007; wrap, 2007a).
Q12. Why did the blue group choose to participate in the study?
This group of households was chosen for the study because they were believed to be more observant of reasons for food waste than ordinary households.
Q13. What is the main reason why one-person households waste more?
Since one-person households waste more per capita, and since it is an increasing household type in Europe, it would be interesting to further study this groups’ packaging related waste.
