\subsection{Sorting analysis}  In previous studies sorting analyises have been proven an effective method to reveal the most frequently wasted food products, i.e. milk and dairy, bread, vegetables, fruits, sauces, oil and fats \citep{van_westerhoven_bepaling_2013}. In this research the data obtained from the sorting analysis will be used quantify the environmental impacts for each household per product group. The environmental impacts are approximated by the amount of avoidable (a) CO_2 emissions from all supply chain stages prior to consumption, (b) litres of freshwater use required for cultivation, (c) km^2 of fertile land required for cultivation.  \subsection{Lifecycle assessment}  % Please add the following required packages to your document preamble:  % \usepackage{booktabs}  \begin{table}[h]  \begin{tabular}{@{}llllll@{}}  \toprule  \textbf{\begin{tabular}[c]{@{}l@{}}Food supply chain stage/\\ Resource use\end{tabular}} & \textbf{Cultivation} & \textbf{Processing} & \textbf{Retail} & \textbf{Household} & \textbf{Waste collection \& treatment} \\ \midrule  & \multicolumn{5}{c}{Transportation} \\  Fertile land & \begin{tabular}[c]{@{}l@{}}Cultivation of crops\\ Livestock raising\end{tabular} & - & - & - & Landfilling space \\  Water & Irrigation & Cleaning & - & Cooking & - \\  CO2 & \begin{tabular}[c]{@{}l@{}}Livestock emissions\\ Machine use\end{tabular} & \begin{tabular}[c]{@{}l@{}}Processing\\ Machine use\end{tabular} & Operation & \begin{tabular}[c]{@{}l@{}}Cooking\\ Storage \& cooling\end{tabular} & Incineration \\  CH4 & Livestock emissions & & & & Biogas production \\ \bottomrule  \end{tabular}  \end{table}  \subsection{Questionnaire}  Together with Groningen University a questionnaire has been designed to gain insights into the behavioural component in relation to waste production and separation. It has been supplemented with the following food waste specific questions:

%Within these households, semi-structured interviews will be performed to gain a better understanding on the reasons for wasting certain types of food and the physical occurrence of the waste within the household. A Sankey diagramm will be greated for a selection of these households to visual the food waste streams within households. Ethnography methods will be used to investigate daily practices  %thereby using Self-Determination Theory (SDT) \cite{deci2002handbook}   %I will use a material footprint analysis \cite{Lettenmeier_2014} \subsection{Semi-structured interviews}
