Es scheint ein allgemeines Bewusstsein dafür zu geben, dass es sowohl ökologisch als auch sozial notwendig und erwünscht ist, den Einsatz von Kunststoffen auf Basis fossiler und damit endlicher Ressourcen zu reduzieren. Zugleich sind sie jedoch aus dem Konsum- und Lebensalltag nicht mehr wegzudenken: Ein Leben ohne Kunststoffe ist für etwa ein Viertel der deutschen Bevölkerung unvorstellbar – auch wenn zugleich der Wille bekundet wird, auf Kunststoffe aktiv zu verzichten (29 %) bzw. man dies eigentlich tun möchte (48 %) (Blesin et al. 2017).

Im Projekt wurde eine Studie an 39 Senioren in 2 Pflegeeinrichtungen durchgeführt. Ziel war es, Anreicherungstechniken für eine komplette Nährstoffanreicherung zu entwickeln, in verschiedenen Pflegeeinrichtungen durchzuführen, sowie die Entwicklung von neuen kostengünstigen Proteinformulierungen. Die Pflegekräfte können damit, dem Probanden die gewünschte Menge Proteinsahne geben und stellen so die Nährstoffaufnahme sicher. Zudem konnten bei der Studie Mahlzeiten für Bewohner mit Kau- und Schluckbeschwerden verbessert werden. Diese Personen bekamen vor der klinischen Studie täglich püriertes Essen. Um den optischen Eindruck zu verbessern, wurde dies in der Studie mit einem Texturierungsmittel versetzt und mit Silikonformen wieder in die originale 3D Form gebracht. Vor dem Servieren wurden die Lebensmittel aus den Formen gelöst, auf den Teller gegeben und erwärmt. Das Pflegepersonal bestätigt, dass die Bewohner ihr Essen wieder besser erkennen konnten und eine deutlich höhere Begeisterung für die Mahlzeiten haben. Ziel des 2. Projektteils war es, die Wirksamkeit personalisierter Preispromotionen für gesunde Lebensmittel in Supermärkte zu testen, um Konsumenten zu einer gesünderen Lebensmittelwahl zu bewegen. Hierzu wurden auf Basis von Verbraucherpaneldaten verhaltensbezogene Verbrauchersegmentierungen für verschiedene Warengruppen durchgeführt. Zur Bestimmung der Einflüsse von maßgeschneiderten Aktionen auf den Kauf von fettarmen Produkten wurden ein Modell und eine simulationsbasierte Methode entwickelt. Der Ansatz basiert auf einem gemeinsamen Modell aus Kaufereignis, Wahlentscheidung und Kaufmenge und wurde für verschiedene Ebenen umgesetzt. Zudem wurden die Absatzahlen verschiedener Filialen eines Lebensmittelhändlers für definierte Warengruppen vor und nach einer Preisreduktion untersucht. Die Ergebnisse einer Online-Studie zeigen, dass bei der Entscheidung für Joghurt die Inhaltsstoffe die wichtigsten Entscheidungskriterien für Probanden darstellen.

Im interdisziplinären Forschungsprojekt „Verbraucherreaktionen bei Plastik und dessen Vermeidungsmöglichkeiten am Point of Sale“ (VerPlaPoS) wurden im Zeitraum Oktober 2017 bis März 2021 von verschiedenen wissenschaftlichen Institutionen in Zusammenarbeit mit Partnern aus der Praxis Handlungsoptionen und die Rolle von Verbraucher*innen bei der Vermeidung von Plastik(müll) in den Bereichen Lebensmittel- und Textilverpackungen untersucht. Das Projekt wurde gefördert vom Bundesministerium für Bildung und Forschung (BMBF) innerhalb des Forschungsschwerpunkts „Sozial- ökologische Forschung“ im Rahmen der Fördermaßnahme „Plastik in der Umwelt – Quellen, Senken, Lösungsansätze“. Diese ist Teil der Leitinitiative Green Economy des BMBF-Rahmenprogramms „Forschung für Nachhaltige Entwicklung" (FONA3). Im vorliegenden Dokument werden ausgewählte Arbeiten und Ergebnisse zu den verschiedenen Themenbereichen in einzelnen Kapiteln beschrieben.
Nachhaltiger Konsum wird in Deutschland heutzutage immer wichtiger und ist in diversen Sektoren vertreten. Die Relevanz einer sozialen, ökologischen und wirtschaftlichen Entwicklung mit Rücksicht auf zukünftige Generationen wird auch bei privaten Kunden immer bewusster wahrgenommen. Das war auch eines der 17 Ziele, die am Klima Weltgipfel 2015 von den Vereinten Nationen verabschiedet wurde (Becker 2017). Durch das wachsende Umweltbewusstsein etablieren sich verschiedene Formen des nachhaltigen Konsums, wie beispielsweise regionaler, grüner und ethischer Konsum. Neue Nachhaltigkeitsaspekte fordern oft auch neue Zertifizierungen (Dressler 2017) zur Individualisierung der Produkte. Diese Entwicklung zeigt sich auch im Gartenbau, speziell im Zierpflanzenbereich (Transfair e.V. 2018). Die vorliegende Studie beschäftigt sich mit der Verbrauchereinschätzung zur Fairtrade Zertifikation bei Schnittrosen, die primär soziale und ökologische Aspekte bedient. Insgesamt hat sich das Marktvolumen von Zierpflanzen in den letzten Jahren nicht viel verändert und stagniert mit leichten Schwankungen um 8,7 Milliarden Euro. Ein Umsatz von etwa 3 Milliarden Euro kommt allein von Schnittblumen, und fast die Hälfte davon machen Schnittrosen aus (BVE 2017). Somit ist der deutsche Schnittrosenmarkt der größte Europas (CBI 2017). Etwa jede vierte verkaufte Rose in Deutschland ist Fairtrade zertifiziert, und die meisten davon werden über den Lebensmitteleinzelhandel (LEH) verkauft (Transfair e.V. 2018). Für den Handel wäre es von großem Interesse zu wissen, was die Motive von Fairtrade-Rosen Käufern sind, und wie sich diese von Nichtkäufern unterscheiden lassen. Im Rahmen dieser Studie haben wir die Unterschiede zwischen den zwei Gruppen, anhand diverser Kaufverhalten und Einstellungsmerkmale, identifiziert.

Considering global plastic waste pollution, current production and consumption patterns must be changed. Various measures address this challenge, which can be divided into efficiency, consistency, and sufficiency. Sufficiency has become more critical as research on sustainable consumption and packaging-related behavior has shown that efficiency and consistency strategies alonecannot solve environmental challenges. A deeper understanding of consumers’ packaging-related behavior is necessary to promote sufficiency-oriented consumption patterns and support consumersin everyday implementation. This study aims to investigate consumers’ packaging-saving practices in the fast-moving consumer goods (FMCG) sector and to explore to what extent the practices differ in their actual feasibility in everyday life. For this purpose, we conducted an online survey in Germany with open-ended questions (n = 299). We evaluated the open-ended questions using qualitative content analysis. Overall, the results show that reducing plastic packaging plays a significant role in the participants’ everyday lives. However, the extent to which plastic packaging is avoided or reduced varies by consumption sector. This study extends research on plastic packaging avoidance and reduction to non-food consumption sectors. It also provides essential impulses for actors from science, politics, and industry regarding how consumers can be more strongly supported in their packaging-related behavior in the future, through targeted measures.

Predictive models are increasingly crucial in navigating heterogeneous markets. This study develops a predictive model approach to forecast consumer cluster membership in the green fast-moving consumer goods sector, focusing on bio-based products like adhesives and plasters. Through two online surveys in Germany, we identified key factors acting as drivers and barriers, demonstrating their effectiveness in distinguishing similar consumer segments across both product categories. Utilizing multinomial logistic regression, we crafted a prediction model that accurately forecasts cluster membership, providing novel insights into consumer behavior towards non-food bio-based products. This facilitates the development of targeted business and marketing strategies, optimizing resource allocation in market research activities. Our findings offer significant contributions to understanding the dynamics influencing consumer choices in the bio-based product market.

Purpose – The purpose of this study was to investigate how and through which social-cognitive constructs, emotions influence healthy food shopping behaviors. Direct effects of those constructs, as well as indirecteffects of consumer emotions are considered.Design/methodology/approach – An altered version of the Social Cognitive Theory, including intention, socio-structural factors, outcome expectancies and self-efficacy with the addition of consumer emotions wasanalyzed using structural equation modeling. Data of 1,181 volunteers were collected in Germany in 2021through an online survey.Findings – Intention was the most important positive predictor of food choice, while socio-structural factorshad the biggest impact on intentions. Those were mostly influenced by self-efficacy, which was stronglypredicted by consumer emotions. Outcome expectancies did not influence the current model in any way. Consumer emotions did not directly influence intention, nor actual choice, however showed to be influencingthose variables through indirect effects.Practical implications – Marketers could benefit from these results by incorporating the current findings into existing marketing strategies through targeting a combination of social cognitive constructs, as well asconsumer emotions to facilitate healthier food shopping behavior.Originality/value – Affect has received increasing attention in regards to its impact on healthy eatingbehaviors in recent years. Less attention has been paid to the mechanisms through which emotions influence healthy nutrition behavior, specifically how consumer emotions influence healthy food shopping behavior.
Natural cosmetics offer the opportunity to reduce the environmental burden caused by the consumption of cosmetic products. This qualitative study analyzes the local range of natural cosmetics and related consumer perceptions and assessments in two case cities in Germany by applying a mixed-method approach of store checks and the photovoice method. Results of the study show that there is only a limited match of the actual range and consumer perception for some types of retail businesses and a mismatch for product categories. Additionally, participants showed little awareness of the most common natural cosmetic certifications. Consumer assessments about the range of natural cosmetics were influenced by factors such as the arrangement of products in the shops and consumers' experience and knowledge about natural cosmetic brands. Retailers can use the study results in arranging natural cosmetics accordingly; companies can use it to emphasize branding, and policy-makers can increase consumer knowledge about natural cosmetics.

Background Food-related behaviour is a very complex topic. A common way to reduce complex issues to their essential content is to create a typology. In Germany, with regard to food-related behaviour, the creation of a typology has often been carried out by commercial research institutes, but also by (international) scientific institutes. The former have mostly used quantitative methods, the latter usually have a specific content focus. Within this study, we want to investigate how people integrate eating into their everyday lives while engaging with themselves and the environment, thereby living out personality development and related socialisation.Methods 37 qualitative interviews were conducted and evaluated by means of content-structuring qualitative analysis and type-forming qualitative content analysis. Interviewees were recruited via recruitment calls using different channels, such as newspapers or university e-mail lists. Participants over the age of seventeen were eligible to take part in the study. Both the individual action processes and the interpretation processes regarding food-related behaviour were taken into account. The final sample consisted of 20 male and 18 female participants with an age range from 18 to 83. Results The result were seven eating action types, namely: Eating as a way of life, The Relaxed, Eating as selfdetermination, Eating as a necessary Evil, The Adaptive, The Overstrained and The Controlled. Conclusions We contribute to the study of food-related behaviour with the chosen qualitative method of typebuilding and by looking at how people integrate eating into their everyday lives. This contributes to a broader understanding of this phenomenon and complements the findings of existing commercial and academic foodrelated typing-building activities. Specifically, through identifying “The Overstrained” as a novel eating action type, this study adds to the literature in the field and may be a useful baseline for future research. Keywords Food-related behaviour, Eating action, Qualitative type-building content analysis, Typology, Personality development
BackgroundNatural health products (NHP) are an important part of the healthcare system. They are mainly non-prescription and sold over the counter, which requires active decision making by the consumer. Within the framework of the Complementary and Alternative Healthcare Model, this study aims to identify factors that influence NHP usage, in particular related to concentration and cognition (CC), a topic that concerns all ages and social classes within the population.MethodsData were collected by means of a representative online survey (n = 1,707) in Germany in April 2022. Three user groups were defined: NHPCC users, who used NHP for CC (12 month prevalence); nCC-NHP users, who used NHP but not for CC indications (12 month prevalence); and past NHP users, who have used NHP but not within the previous 12 months. Independent influencing variables were categorized into predisposing, enabling, need, and health service use factors. Data were analyzed with descriptive statistics, inferential statistics, and binary logistic regression models to compare NHPCC users to nCC-NHP users (model 1) and to past NHP users (model 2).ResultsA higher share of NHPCC and nCC-NHP users compared to past NHP users were women, self-medicated with NHP, and used information about NHP provided by health professionals or on product. Their openness-to-change value orientation was more pronounced than of past users. Compared to nCC-NHP and past NHP users, the probability of being an NHPCC user increased if an individual had more difficulties in daily attention and memory performance, made use of health professionals and literature to seek information about NHP, and used NHP for health support and illness prevention. Additionally, a female gender, NHP self-medication, and having higher values of self-transcendence were significant indicators for NHPCC usage compared to past NHP usage.ConclusionNHP manufacturers, health professionals, and policymakers should be aware of the factors that lead to NHP consumption decisions and consider them in the development and optimization of healthcare strategies as well as in the marketing and communication strategies of companies producing NHP, in particular for CC. The current study can contribute to characterizing the target groups and to defining the aims and communication channels of such campaigns.

Accurately forecasting demand is a potential competitive advantage, especially when dealing with perishable products. The multi-billion dollar horticultural industry is highly affected by perishability, but has received limited attention in forecasting research. In this paper, we analyze the applicability of general compared to dataset-specific predictors, as well as the influence of external information and online model update schemes. We employ a heterogeneous set of horticultural data, three classical, and twelve machine learning-based forecasting approaches. Our results show a superiority of multivariate machine learning methods, in particular the ensemble learner XGBoost. These advantages highlight the importance of external factors, with the feature set containing statistical, calendrical, and weather-related features leading to the most robust performance. We further observe that a general model is unable to capture the heterogeneity of the data and is outperformed by dataset-specific predictors. Moreover, frequent model updates have a negligible impact on forecasting quality, allowing long-term forecasting without significant performance degradation.
Using bio-based building products for renovation and refurbishment contributes to a bioeconomy. As private consumers mainly buy building products at local hardware stores, it is essential to consider the local supply situation. This qualitative study analyzes the local range of bio-based building products for renovation and refurbishment and related consumer perceptions and assessments in two case cities in Germany. The study results reveal that consumers face high search costs, the range of products is primarily narrow, and their placement and presentation are unfavorable. Manufacturers can use the study results and invest in classical marketing strategies, and initiate pull strategies with consumers for bio-based building products. This could motivate retailers to increase the range and improve the placement and presentation of such products. Finally, policymakers can apply the insights from this study to educational campaigns and the promotion of quality labels in this field.
Construction and use of buildings is one of the highest users of global energy (34%) and one of the highest contributors to greenhouse gas emissions (37%). Using wood instead of carbon-intensive materials such as bricks reduces a building's embodied energy and is a more eco-friendly alternative. Since the quota of newly built wooden houses in Germany is still relatively low, gaining insights into the perspective of consumers is crucial. This study aims to investigate factors from a consumer perspective that influence the selection of wood as the primary building material for residential houses. Therefore, an online survey was conducted in Germany to gather data from individuals (N = 510) who either bought or built a house in the last 5 years. By conducting a logistic regression, we have identified six influencing factors for the selection of wood. Positive views on wood's eco-friendliness and emphasis on renewable materials are key factors in choosing wood. Higher age and living in rural areas also increase the likelihood of selecting wood, while concerns about value stability and durability have negative effects. We conclude that increasing information activities, raising awareness about wood's ecological benefits, and dispelling prejudices can significantly impact its selection as a preferred building material.
Purpose This paper aims to determine, which values guide consumers decision-making on natural health products for concentration and cognition (NHPCC) and how they link to choice-relevant product attributes. The purpose is to contribute to a better understanding of NHPCC consumption choices, which can encourage more consumer-centric product development and positioning.
