Kitchen wasteKitchen staff produce most of the food waste during preparation time, whereas the hall staff collect the leftovers as organic waste. Independent of whether a restaurant serves lunch and/or dinner, the chef(s) usually start their preparations in the morning. This way they make preparations for both the lunch and evening sessions. Preparation time is mostly characterized as being calm, meaning that there is time to sort without much stress and distraction. The amounts of food waste are relatively large but homogeneous.Focusing on how the organic waste is managed in the kitchen, we found the following based upon the observations. In almost all observed kitchen areas, every chef has at least one personal garbage bin, or multiple small containers that are spread around their working space (see Table 2). These containers allow work to be more efficient and keep the working area clean. In addition, a large trash can is nearby, and the waste is thrown directly into it. The garbage is collected in the bins until they are full, after which they are emptied into the trash can. A compromise is made between the size of the container and the number of times the cook has to walk back and forth to empty it, as well as the available space in the kitchen. These operations are important for the support of separate food-waste collection. In addition, the added value of this temporary medium is the opportunity to check the waste before it is transferred to the larger food-waste collection point.
