Causes of food waste

The most comprehensive set of studies on household food waste to date was conducted by the British organization WRAP.
Their results led to the conceptual framework to understand household food waste prevention FIGURE.
The amount of avoidable food waste found in a household is the result of multiple, interconnected behaviors.
These are behaviors related to practices such as cooking, buying food, or storing food.
How these behaviors are expressed depends on a set of household characteristics (e.g. attitudes, habits, knowledge).
The retail supply chain influences how households negotiate with food through the design of products (e.g. shelf life), product packaging (e.g. labeling), and the retail locations (e.g. price promotions).
Cultural norms, laws and governments, demographic trends, technological change, economic development and industrial change provide, although less directly than the retail supply chain, an additional influence on how households negotiate with food.
