WP1 Best practices for food waste prevention
The project includes case studies in the serving sector in the participating countries.
Investigation of causes
There are plenty of reasons why food waste occurs. Often there is traceability to different levels of the catering service. Important levels are the production stage (kitchen), the service stage (serving of food), the management stage and lastly the customer stage. Beginning with unavoidable food waste like bones or peels of fruits, which occur in the kitchen, it leads on to avoidable service waste which is the point where most of the measurements focus on. When the management of a catering service doesn’t implement a customized order, there is a risk that food waste occurs (Derqui et al., 2018). Studies could detect other several reasons for an increasing amount of food waste. For example the motivation and knowledge of the staff regarding food waste minimization occurs to be one important factor when talking about reasons for food waste (Silvennoinen et al., 2005; Derqui et al., 2018). On the customer level a cause for food waste can be found for example in the plate waste. Eriksson (2017) could detect that the catering in elderly care homes produce far more food waste than the ones in schools and preschools. On the production stage inadequate kitchen or production processes lead to more waste (Waskow, Blumenthal, 2016). Additionally not customized meal plans or the lack of attention to dietary habits of the customers have an impact on the level of food waste as well (Falasconi, 2015). On the service stage, one reason for food waste is the distribution of portions that are too large and therefore not according to reference values for portion sizes (Balzaretti et al., 2018). The case studies in the work package 1 of the project AVARE try to detect reasons for the occurrence of food waste in practice, by performing food waste measurements and conducting an online survey. Besides this stakeholder workshops aim to find solutions for minimizing the causes leading to food waste. Overall aim is to find recommendations for different setting and situations since the different measurements are already known.
