With increasing annual customers, the sector’s impact on the environment is also growing continuously. At the same time, public catering offers a lever to promote sustainable nutrition that has rarely been used so far. Small changes in kitchen practices and food offers can thus be multiplied into a significant positive impact on environmental challenges, such as climate change or loss of biodiversity due to the large number of servings. In contrast to private households, management decisions in public catering can influence the food- related environmental impact of thousands of customers. This article deals with the nationwide level of greenhouse gas (GHG) emissions and resource use in the German public catering segment “business” and its saving potentials by different scenarios of unsupported and supported recipe revision. In this paper, we define "unsupported" as the intuitive optimization of recipes by employees of public catering businesses. In contrast, “supported” approaches had to meet specific target goals, for example of the Deutsche Gesellschaft für Ernährung; engl. German Nutrition Society or the sustainable level. Specifically, we will test how (A) an unsupported recipe revision, (B) a recipe revision based on dietary recommendations and (C) a recipe revision using scientific guidance affect the environmental impact of a dish. As a methodological framework, an online survey of public catering companies was conducted as well as a scenario analysis at menu level and at nationwide level. The results are based on empirical data on the one hand, and on extrapolations on the other. The results show that the nationwide implementation of recipe revision according to scientific guidance—such as concrete target goals for the GHG emissions per serving—can save up to 44% of resource use in the German business catering sector (which corresponds to 3.4 million tons of resources per year) and as much as 40% of GHG emissions (0.6 tons GHG emissions per year). Even in the scenario of unsupported recipe revision, GHG and resource savings of up to 20% can be realized. The results show that public catering can reduce its material and carbon footprint by 20% overnight. Moreover, the findings show indications for the sustainable transformation of public catering. Nevertheless, it must be noted that these are some first steps of the transformation, which will require further changes with even greater impacts and political activities.

After retail, out-of-home catering is the second largest food sales channel in Germany. A variety of means on both the supply and demand side are necessary to stimulate, facilitate and encourage a more sustainable development and minimise GHG emissions in this sector. Nudges are one of these. This paper's focus lies on the demand side. Set in real-world laboratories, we use a standardised empirical approach to compare different nudging interventions belonging to the area of physical environment and consumers’ choice making process. We compare the effects of the same intervention across different settings and the effect of different, sequential nudging interventions in the same setting. Data was collected in eight workplace and school cafeterias in Germany over two project iterations (2016/2017; 2019/2020). A similar intervention design was applied. Comparability was assured by a harmonised menu. The first project iteration revealed that only one nudge (top menu position, +22.5%) led to significant increases in sustainable food choices, while results from the second iteration showed that all nudge interventions (best counter position, +11.6%; top menu position, +6,9%; label plus information, +15.9%) positively influenced consumer choice. Possible explanations such as the stricter compliance to the experimental design in the cafeterias but also societal developments such as the appearance of the Fridays for Future movement are discussed. As results vary between specific locations and settings, our findings suggest that nudges need to be adjusted to situational conditions for achieving highest efficacy.

Das Institut für nachhaltige Ernährung und Ernährungswirtschaft (iSuN) der Fachhochschule Münster wurde gemeinsam mit der Verbraucherzentrale Nordrhein-Westfalen beauftragt, die Studie mit dem Schwerpunkt der Identifikation von Ursachen und Handlungsoptionen zur Verringerung von Lebensmittelabfällen in Nordrhein-Westfalen durchzuführen. Der Lebensmittelmarkt ist stark arbeitsteilig organisiert und global vernetzt. Die Situation in Nordrhein-Westfalen unterscheidet sich dabei nicht wesentlich von der in ganz Deutschland oder in Europa. Die Orientierung auf Nordrhein-Westfalen erfolgte über die Auswahl von Interwiepartnern und Unternehmensexperten sowie über die Auswahl der für Nordrhein-Westfalen besonders relevanten Produktgruppen Gemüse, Brot und Backwaren, Milch und Milchprodukte sowie Fleisch und Wurstwaren. Handlungsoptionen zur Verringerung von Lebensmittelabfällen in Nordrhein-Westfalen sind prinzipiell auf andere Bundesländer in Deutschland übertragbar. Die Studie setzt sich aus insgesamt vier Forschungsbausteinen zusammen. Im Forschungsbaustein A werden die Ursachen von Lebensmittelabfällen für die vier relevanten Produktgruppen analysiert und Handlungsempfehlungen zur Reduzierung von Lebensmittelabfällen abgeleitet. Betrachtet werden die jeweiligen Wertschöpfungsketten von der Landwirtschaft bis zum Handel. Die analysierten Ursachenfelder zeigen stufenübergreifende Wirkungen innerhalb der Wertschöpfungskette, die zu Lebensmittelabfall führen. Aus diesem Grunde ist besonders die Betrachtung der Schnittstellen für die Entwicklung von Maßnahmen entscheidend. Forschungsbaustein B untersucht auf der Grundlage persönlicher Interviews und anonymer Onlineinterviews Ursachen, die Verbraucherinnen und Verbraucher veranlassen, Lebensmittel wegzuwerfen und leitet daraus Empfehlungen zur Verringerung von Lebensmittelabfällen ab. Die Befragungen zeigen, dass insbesondere komplexe, oft schlecht planbare Lebens- und Arbeitssituationen dazu führen, dass Lebensmittel weggeworfen werden müssen. Forschungsbaustein C analysiert statistisch verfügbare Daten, aus denen sich Lebensmittelabfallmengen für Nordrhein-Westfalen hochrechnen lassen. Forschungsbaustein D zeigt auf, dass die Entstehung von Lebensmittelabfällen nennenswerte soziale, ökonomische und ökologische Wirkungen nach sich zieht, die zu beachten sind. Mit der modellhaften Betrachtung der Ressourcenverbräuche und Umweltbelastungen ausgewählter Lebensmittel werden die Dimensionen der ökologischen Wirkung von Lebensmittelabfällen deutlich gemacht. Die Ressourcenverbräuche in den Vorketten der Lebensmittel betragen ein Vielfaches des Abfallaufkommens. Die ökologischen Fußabdrücke von Lebensmitteln der vier Produktgruppen verteilen sich anders als das Abfallaufkommen, da den verschiedenen Lebensmitteln unterschiedliche Ressourcenverbräuche zugeordnet sind. Bei den Lebensmittelabfällen hat die Produktgruppe Obst und Gemüse mengenmäßig den größten Anteil, dafür aber einen deutlich geringeren Anteil an den Ressourcenverbräuchen als Fleischprodukte. Aus dem Kontext der vier Forschungsbausteine leitet die Studie Handlungsvorschläge zur Verringerung und Vermeidung der Lebensmittelabfälle in Nordrhein-Westfalen in den vier grundlegenden Kategorien "Prozessoptimierung/Schnittstellenmanagement", "Strukturen und Regeln", "Verwerten statt Entwerten" sowie "Wertschätzen und Aufwerten" ab. Anhand dieser Handlungsfelder können konkrete Ansätze für die Teilnehmer des Runden Tisches "Neue Wertschätzung für Lebensmittel" aber auch für die Politik in Nordrhein-Westfalen abgeleitet werden, um Lebensmittelabfälle zu vermeiden und "neue Märkte" zur Reduzierung von Warenverlusten bzw. Weiterverwendung von Lebensmittelabfällen zu identifizieren. N2 - The research project "Reducing Food Waste - Identification of causes and courses of action in the German State of North Rhine-Westphalia" ("Verringerung von Lebensmittelabfällen - Identifikation von Ursachen und Handlungsoptionen in Nordrhein-Westfalen") (timeframe: 9/2011 - 2/2012) is connected to the discussion on a new appreciation of foodstuffs and a sustainable lifestyle. The Institute of Sustainable Nutrition and Food Production (iSuN) of the University of Applied Sciences Münster and the Consumer Center of North Rhine-Westphalia were given by the Ministry for Climate Protection, Environment, Agriculture, Nature Conservation and Consumer Protection (MKUNLV) the task of conducting a study, focused on the identification of causes of food waste and possible courses of action in North Rhine-Westphalia. The food market operates highly globalized and works based on a division of labor and the north rhine-westphalian situation does not differ much from the German or European situation. Orientation towards North Rhine-Westphalia within the study was achieved by the choice of interview-partners and business experts. This orientation was further supported through the choice of the locally relevant product groups vegetables, bread and bakery, milk and milk products as well as meat and sausage products. Courses of action for a reduction of food waste in North Rhine-Westphalia can possibly be transferred to other German federal states. The study consists of four research-components. Research-component A analyses the causes of food waste within the four relevant product groups and deduces the implicit possibilities for procedure recommendations. The analysis of causes is based on the value chain of the specified product group, from agriculture to retail. The potential arrays of causes show that practices which lead to food waste often take effect across various levels of the value chain. Therefore it is important to take the interfaces between levels into account, in order to develop practical measures that decrease creation of food waste. The analysis of face-to-face interviews and anonymous online-interviews in private households was performed in Research-component B. Therein, reasons for the wasting of foodstuffs through consumers were detected and based on the findings, recommendations to reduce food waste are made. The interviews show that, especially, the complex and unpredictable lifestyles and job-situations lead to the tossing of food. Research-component C analyses the available statistics, in order to gain data on the amount of food waste produced in North Rhine-Westphalia. Research-component D shows that the creation of food waste leads to considerable social, economic and ecologic effects. The dimensions of ecological effects of food waste are shown through an exemplary consideration of the consumption of resources and environmental effects of selected foods. The foodstuffs consume resources within the upstream chain, that amount to multiples of the waste that is later created through the tossing of these foods. Within foods from the four examined food groups, ecologic footprints divide differently from the way, the amount of waste created through them divides. This is due to the different amounts of resources that are used up per kilogram of each food. While vegetables and fruits are accountable for the highest amount of food waste, their share of the consumption of resources is lower than that of meats. Out of the four research-modules, the study devises commendations on reducing food waste in North Rhine-Westphalia within the four categories "process enhancement/interface management", "structures and rules", "Re-use/recover instead of devaluate" and "appreciate and enhance". Based on these categories, practical approaches can be developed for the participants of the round table "new appreciation for food" ("Neue Wertschätzung für Lebensmittel") as well as for north rhine-westphalian politics, in order to avoid the creation of food waste and to find new markets that can help to reduce the loss of goods or to find subsequent uses for discarded foods.
