\section{Introduction}  \subsection{Societal background or problem}  Globally, about one-third of food produced for human consumption is lost or wasted, equalling an estimated amount of 1.3 billion tons pear year \cite{gustavsson_global_2011}. The differences between the continents are enormous. In Europe and North America, consumers waste around 95-115 kg/year, compared to only 6-11 kg/year in sub-Saharan Africa and South/Southeast Asia. These are the results of a study commissioned by the Food and Agriculture Organization of the United Nations to raise awareness on the dramatic situation of inefficient food utilisation. Food wastage not only poses an ethical dilemma regarding people suffering from hunger but has significant environmental implications: primarily the unnecessary use of land, water, labour and energy to produce food doomed for spillage.  Globally, about one-third of food produced for human consumption is lost or wasted, equalling an estimated amount of 1.3 billion tons pear year \cite{gustavsson_global_2011}. In Europe and North America, consumers waste around 95-115 kg/year, compared to only 6-11 kg/year in sub-Saharan Africa and South/Southeast Asia.

Food wastage not only poses an ethical dilemma regarding people suffering from hunger, Westerhoven2013Bepalingbut has significant environmental implications: primarily  theunnecessary use of land, water, labour and energy to produce food doomed for spillage.   With food wastage representing a global  problem, many countries have taken tackled  the challenge to significantly reduce food wastage. In the Netherlands, the government aims at reducing food wastage by 20\% until 2015. However, there are only a limited amount of studies dedicated to food wastage in Dutch households. A widely cited study was done by \citep{Westerhoven2013Bepaling}. They key findings were: \begin{itemize}  \item About 14\% of the purchased food is thrown away by households;

The first question addresses the relationship between daily, recurring activities of households members and food waste spillage. It is investigated which of these activities have an enforcing (diminishing) influence, such as shopping planning behaviour, mode of transportation used to go for shopping. People have different options to dispose food leftovers which has different implications on the environmental effects and the requirements of the waste collection and treatment infrastructure. The second question aims at finding out the sources of food wastage, i.e. the physical location of the disposal of food. Does food wastage primarily occurs   \section{Theory}  Food loss refers to the decrease in edible food mass throughout the part of the supply chain that specifically leads to edible food for human consumption, i.e. production, post-harvest and processing stages in the food supply chain \cite{20713403}. Food losses are specified and referred to as food wastage if it is related to retailers' and consumers' behaviour.  \section{Methods}  Participants observation
