# Summary  Large volumes of food are wasted in Dutch households. Households are responsible for 38 percent of the entire waste along the food supply chain. Several studies found how the amount of food waste in households is influenced by the way people organize their household life around the practice of eating as well as their abilities to cope with everyday life contingencies. In this master's thesis I qualitatively compare and contrast how two non-representative groups of Dutch households organize their household life around the practice of eating and how they cope with everyday life contingencies that disrupt normal provisioning routines. One group is characterized by households that voluntarily participated in the public engagement campaign "100-100-100" that aimed at a general reduction of residual household waste and improved sorting performance. The other group is characterized by "ordinary" households in the sense that I selected them without any particular selection criteria other than to investigate daily life. Drawing upon the results of a content analysis of 203 open-ended text responses, I found that 100-100-100 households: (1) have acquired simple routines to reuse leftover products shortly after their occurrence or preserve them over the long-term for future use; (2) are characterized by people with a "maker culture" and a positive attitude towards experimentation and do-it-yourself; (3) remain affected by everyday life contingencies in the form of well-intended food gifts and donations which, however, are not part of existing routines and thus create a difficulty to be utilized. To the contrary, the "ordinary" households in my study: (a) were in various ways affected by everyday life contingencies that disrupted existing practices around eating and led to the unintended over-provision of food; (b) expressed widely shared emotions of anger, sadness, dislike and discomfort associated with wasting food; (c) were in many situations aware of the problem and able to articulate effective solutions to prevent food waste but failed to implement these in their daily household life. Some contingencies of everyday life, however, unavoidably disrupt household life and go beyond the scope of the household. At this point, food waste becomes a wider cultural issue that needs to be addressed at all places of provision, ranging from retailers to the personal workplace. A public debate is necessary to negotiate the responsible utilization of food aside the background of a perceived over-abundance and availability of food. Household food waste is unlikely to be reduced significantly if the wider problem of affluence and over-consumption is not solved.
