Der Beitrag zeigt im Projekt „Gerechte und nachhaltige Außer-Haus-Angebote gestalten“ entwickelte Bildungsangebote auf, durch die handelnde Menschen in Großküchen motiviert und befähigt werden betriebliche Arbeitsprozesse nachhaltiger zu gestalten. Berücksichtigt werden Gelingensbedingungen wie der persönliche Austausch in Gruppen von Arbeits- und Berufskolleginnen und -kollegen sowie knappe zeitliche Kapazitäten.
The generation of bread waste at suppliers and retailers is often linked to the production of surplus bread. This study reports the results of the first direct quantification and economic assessment of surplus bread conducted in Italy, involving a panel of 12 bakeries and their branches located in the Lazio region, which compiled a daily diary for 5 months. They are small-scale bakeries which reflect the typical structure of the Italian businesses in the bakery sector, producing fresh bread and selling it directly to consumers. The surplus bread measured during the study consists of 6,694 kg in total, with an average quantity of 4.83 kg/day per bakery. Studying the three main products (common bread, focaccia bread and bread rolls), the average rate of surplus is respectively 5.88 %, 3.99 % and 5.28 % of the production. The corresponding economic loss represents, on average, 5.44 % of the daily turnover. A set of factors seems to exert highest influence on the generation of surplus, as the range of production, location and number of customers. When surplus bread occurs, in 63 % of the cases it is managed on alternative routes to avoid disposal. Even if detected surplus bread does not necessarily become waste, it indeed represents a big loss for bakeries.
Eine nachhaltige Transformation der Berufswelt setzt voraus, dass die Berufsbildung die dafür nötigen Kompetenzen vermittelt. Aber welche Aspekte der Nachhaltigkeit sind überhaupt berufs- bzw. ausbildungsrelevant? Über welche Kompetenzen müssen Auszubildende verfügen, um im Beruf nachhaltig handeln zu können? Der vorliegende Beitrag nimmt sich dieser Fragen am Beispiel der Berufe der Lebensmittelproduktion an. Ziel des Beitrags ist die Herleitung eines Strukturmodells, das domänenspezifische
Nachhaltigkeitskompetenzen entlang der Dimensionen beruflicher Handlungskompetenz beschreibbar macht. Das entwickelte Modell kann Impulse für die curriculare und didaktische Berufsbildungsarbeit
setzen, aber auch für die Neuordnungen von Ausbildungsberufen
Als Erweiterung des Förderschwerpunkts „Berufsbildung für nachhaltige Entwicklung“ (BBNE) und aus
Mitteln des Bundesministeriums für Bildung und Forschung hat das Bundesinstitut für Berufsbildung in der Förderlinie III Modellversuche zur Entwicklung nachhaltigkeitsorientierter Kompetenzen in Lebensmittelhandwerk und -industrie gefördert (2018–2021). Trotz unterschiedlicher Herausforderungen der
Modellversuche, auch begründet durch berufsspezifische Gegebenheiten, steht das übergeordnete Ziel im Vordergrund, domänenspezifische Nachhaltigkeitskompetenzen in Berufen des Lebensmittelhand-
werks und der Lebensmittelindustrie zu entwickeln. Denn wie Lebensmittel produziert und konsumiert werden, hat einen entscheidenden Einfluss auf die nachhaltigkeitsbezogenen Auswirkungen unserer Ernährung. Lebensmittel sollen nicht nur satt machen, sondern gleichzeitig fair und umweltgerecht produziert werden, gesundheitsfördernd, schmackhaft und sicher sein. Lebensmittelproduzierende Betriebe in Industrie und Handwerk stehen vor der Aufgabe, diese vielfältigen Anforderungen zu erfüllen und somit auch dazu beizutragen, zukünftigen Generationen ein gesundes Leben zu ermöglichen. Dieser einführende Beitrag zeigt auf, warum der Beitrag der Berufsbildung zur nachhaltigen Entwicklung unse-
res Ernährungssystems so wichtig ist. Dazu stellt er die Auswirkungen des Ernährungssystems auf die
Umwelt und Gesellschaft dar. Gleichzeitig weist er auf die Herausforderungen und Chancen für Lebensmittelproduzenten hin, die es im Rahmen der BBNE zu berücksichtigen gilt. Zudem werden Impulse für nachhaltige Produktinnovationen vorgestellt.
Food production is responsible for approximately 17% of Germany's greenhouse gas (GHG) emissions. 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.
Public catering has become increasingly important in recent years. 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.
