Food waste has increasingly gained global attention and households are identified as the largest source of food waste along the entire food supply chain. Thus, it is necessary to have a clear understanding of the factors influencing food waste -related consumption behaviours and consumer perceptions in household levels. This study seeks to determine factors causing consumer-related food waste in households. Based on a nationwide survey of 3,335 consumers, this article examined the associations of households’ attributes, attitudes, and behaviours with self-reported household food waste. Using structural equation techniques, household food waste is modeled as a function of the food consumption behaviour, consumers’ perceptions of dietary habits and volume-based waste systems. Results show that making shopping list, environmental attitude, perception for less food waste behavior negatively affect household food waste, while household size, income, food preparation, check expiration date are associated with more household food waste.
