Abstract
A System Dynamics study towards the potential effects of interventions on the food waste produced by households. Households are a major contributor to the waste of food within the Netherlands. There are negative consequences regarding the waste of food. A causal relation diagram is created, a set of interventions is defined, and based upon a System Dynamics model is created. Based upon the simulations, it is concluded that the process in which food is wasted is fragmented. Reducing the waste of food effectively demands combining multiple interventions. There are two important aspects within a household when multiple interventions are applied. Interventions should focus on the 'willingness' and on the 'knowhow' within a household. Focusing on both aspects results in a synergy. The combined effects of the interventions is bigger than the individual effects accumulated.
