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.}, language = {en} } @article{KirschRichertEngelmann2023, author = {Kirsch, Therese and Richert, Monique and Engelmann, Tobias}, title = {Bildungsangebote zur Motivation und Bef{\"a}higung von F{\"u}hrungskr{\"a}ften sowie Mitarbeitenden in Großk{\"u}chen f{\"u}r eine nachhaltigere Verpflegung}, series = {Haushalt in Bildung \& Forschung}, volume = {12.

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 f{\"u}r Ern{\"a}hrung; 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.}, language = {en} } @article{LangenOhlhausenSteinmeieretal.2022, author = {Langen, Nina and Ohlhausen, Pascal and Steinmeier, Fara and Friedrich, Silke and Engelmann, Tobias and Speck, Melanie and Damerau, Kerstin and Rohn, Holger and Teitscheid, Petra}, title = {Nudges for more sustainable food choices in the out-of-home catering sector applied in real-world labs}, series = {Resources, Conservation and Recycling}, journal = {Resources, Conservation and Recycling}, doi = {10.1016/j.resconrec.2022.106167}, year = {2022}, abstract = {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.}, language = {en} } @article{StrotmannBautBoernertetal.2021, author = {Strotmann, Christina and Baut, Vanessa and B{\"o}rnert, Nora and Gerwin, Paula}, title = {Generation and prevention of food waste in the German food service sector in the COVID-19 pandemic - Digital approaches to encounter the pandemic related crisis}, series = {Socio Economic Planning Sciences}, journal = {Socio Economic Planning Sciences}, publisher = {Elsevier}, doi = {10.25974/fhms-13851}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-138519}, year = {2021}, language = {en} } @article{KreyenschmidtRoeslerRitter2021, author = {Kreyenschmidt, Judith and R{\"o}sler, Florian and Ritter, Guido}, title = {Recommendation of Good Practice in the Food-Processing Industry for Preventing and Handling Food Loss and Waste}, series = {Sustainability}, volume = {13}, journal = {Sustainability}, publisher = {MDPI}, doi = {10.25974/fhms-13969}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-139699}, pages = {9569 -- 9599}, year = {2021}, abstract = {Food-processing companies are controlled by societal influences and economic interests, but their efforts with regard to reducing food loss and waste are very different. This qualitative study aims to identify basic recommendations of good practice for the food-processing industry in order to prevent and handle food loss and waste. For this purpose, a comprehensive literature review was conducted in the field of food waste prevention and data was collected from thirteen German companies. The findings summarize the recommendations of good practice, which cover the entire supply chain from supplier to consumer and beyond. The analysis showed that the participating companies are already partially aware of operational measures, even if they are applied or mentioned without a systematic approach. Furthermore, the analysis revealed that most activities relate to internal matters, like processing, employees and utilization. However, the responsibility of foodprocessing companies does not end with internal processes to reduce food waste. The results show that some companies are already aware of their responsibility to be involved along the entire supply chain. Finally, the results show that the needs of consumers and suppliers must also be considered in order to reduce food waste, in addition to direct reduction measures.

In order to evaluate or monitor such important measures it is crucial to obtain quantitative information on generated food waste amounts, subsequently enabling the quantitative evaluation of the measure's outcomes and efficiency. Currently there is a paucity of quantitative information, particularly on food losses that are directly generated during harvesting processes. Up to date, no method is available or standardised aiming at the in-situ or on-site quantification of food losses during harvest. Using the example of the potato harvest, this study presents a practical approach for determining potato losses. To test the applicability of the developed method, on-site measurements were conducted directly on the field at five different locations in Austria and Germany. Our method enables the quantification of food losses based on defined areas along the harvested potato rows, where the analyser manually collects potatoes during their harvest. Hereby, two types of potato losses needs to be considered: non-harvested, under-sized potatoes that remain under the earth and the harvested ones, which are rejected on-site because of quality requirements regarding their size, shape, and state of health. Our study shows that between 1 and 9\% of field losses (based on yield potential) can be generated during the potato harvest. In future, this method may be the basis for standardised protocols in order to be able to derive cultivar-specific benchmarks and, consequently, to develop measures for preventing food losses. In general, more case studies and evidence-based ground-up measurements on other cultivars and for other regions are needed focusing on the on-site quantification of post-harvest losses.}, language = {en} } @article{WeberStrotmannRitter2019, author = {Weber, Ricarda and Strotmann, Christina and Ritter, Guido}, title = {Adressatenspezifische Kommunikationskonzepte zur Lebensmittelabfallreduktion in deutschen Privathaushalten}, series = {{\"O}sterreichische Wasser- und Abfallwirtschaft}, journal = {{\"O}sterreichische Wasser- und Abfallwirtschaft}, publisher = {Springer Vienna}, issn = {1613-7566}, doi = {10.1007/s00506-019-0579-8}, pages = {1 -- 17}, year = {2019}, abstract = {Die Verschwendung von Ressourcen ist ein Symptom unserer heutigen {\"U}berflussgesellschaft und manifestiert sich unter anderem in großen Mengen an Lebensmittelabf{\"a}llen und -verlusten.
