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. This paper highlights nine important stages and 53 basic recommendations for companies to address food loss and waste in order to improve their practices.}, 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{LorenzWaltherLangenGoebeletal.2019, author = {Lorenz-Walther, Bettina A. and Langen, Nina and G{\"o}bel, Christine and Engelmann, Tobias and Bienge, Katrin and Speck, Melanie and Teitscheid, Petra}, title = {What makes people leave LESS food?

Based on a quasi-experimental baseline-intervention design, we analyzed how the display of information posters and the reduction of portion sizes take an effect on personal, social and environmental determinants in a structural equation model. Applying data from online surveys and observations among 880 guests (503 baseline, 377 intervention) during two weeks in a university canteen, the suggested model allows to assign effects from the two interventions on plate leftovers to specific changes in behavioral determinants. Portion size reductions for target dishes are found to relate to lower levels of plate waste based on conscious perception, represented in smaller portion size ratings. Effects from seeing information posters are found to base on changed personal attitudes, subjective norms and perceived behavioral control. However, depending on how an individual reacts to the information (by only making an effort to finish all food or by making an effort and additionally choosing a different dish in the canteen) there are opposite effects on these determinants and consequently also on plate leftovers. Overall, the differentiated results on intervention effects strongly support the benefits of more holistic and in-depth analyses of interventions to reduce plate leftovers and therefore to contribute to more sustainable food consumption in out-of-home settings.}, language = {en} } @article{LukasScheiperAnsorgeetal.2014, author = {Lukas, Melanie and Scheiper, Marie-Louise and Ansorge, Jannick and Rohn, Holger and Liedtke, Christa: and Teitscheid, Petra}, title = {The nutritional footprint - An assessment tool for health and environmental effects of nutrition}, series = {Ern{\"a}hrungs Umschau}, journal = {Ern{\"a}hrungs Umschau}, number = {11}, doi = {10.4455/eu.2014.028}, pages = {164 -- 170}, year = {2014}, language = {en} } @article{PietrangeliErikssonStrotmannetal.2023, author = {Pietrangeli, Roberta and Eriksson, Mattias and Strotmann, Christina and Cicatiello, Clara and Nasso, Marco and Fanelli, Luca and Melaragni, Luigia and Blasi, Emanuele}, title = {Quantification and economic assessment of surplus bread in Italian small-scale bakeries: An explorative study}, series = {Waste Management}, volume = {2023}, journal = {Waste Management}, number = {169}, doi = {10.1016/j.wasman.2023.07.017}, pages = {301 -- 309}, year = {2023}, abstract = {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.}, language = {en} }
