Research on food waste
When product attitudes go to waste
Consumers regularly waste products, but also have an aversion to such wastefulness. The resulting feeling of discomfort can lead to lower product attitudes.

Comparing wasted apples and oranges
Multiple methods to measure household food waste have been proposed, but little is known about their validity. In this study, five methods are compared empirically: general survey questions, diaries, photo coding, kitchen caddies, and weekly survey.

Food waste as the consequence of competing motivations, lack of opportunities, and insufficient abilities
This study explores the motivations, opportunities, and abilities that consumers have for reducing food waste in everyday contexts that involve competing (food-related) goals.

A picture says it all?
Is it possible to assess the amount of food wasted by coding photographs of household food waste? This study examines the validity of this measurement method and finds that the method appears promising for application in studies examining household food waste levels.

Avoiding food waste by Romanian consumers: The importance of planning and shopping routines.
What drives household food waste? This study shows that consumers’ planning and shopping routines are important predictors of food waste.

Missing food, missing data? A critical review of global food losses and food waste data.
A good understanding of the availability and quality of global data on food losses and waste is a prerequisite for tracking progress on reduction targets, analyzing environmental impacts, and exploring mitigation strategies. This paper examines which data is available and where more data is needed.
