    The paradox between the environmental appeal of bio-based plastic packaging for consumers and their disposal behaviour
    Taufik, Danny ; Reinders, Machiel J. ; Molenveld, Karin ; Onwezen, Marleen C. - \ 2020
    Science of the Total Environment 705 (2020). - ISSN 0048-9697
    Bio-based - Consumer behaviour - Disposal - Environmental benefits - Packaging - Plastic

    To realize the potential environmental benefits that recycling and/or composting bio-based plastic packages can deliver, it is important that consumers view bio-based packaging as environmentally-friendly, but also correctly dispose of the packaging. The current experimental lab-in-the-field study was conducted among German consumers (n = 281) and explores whether consumers' perceived environmental benefits of recyclable and compostable bio-based plastic packages match with how consumers dispose of these packages. The results show that consumers only perceive compostable bio-based packages to have more environmental benefits than fossil-based packages. However, consumers dispose of compostable bio-based packages in an incorrect manner (not in line with what is communicated on the packaging label) relatively often. Consumers with a stronger familiarity with bio-based products more often correctly dispose of compostable bio-based packages, but not recyclable bio-based packages, relative to fossil-based packages. Thus, although mainly compostable bio-based plastic packages have strong environmental appeal to consumers, paradoxically this does not translate in the proper disposal actions to fully capitalize on the environmental benefits that bio-based packages can actually deliver. Increasing consumers' bio-based product familiarity might be an avenue to increase the levels of sustainable disposal.

    Choice experiment - Consumer behaviour - Discrete-choice model - Food choice - Individual differences - Regret minimization

    In line with findings on post-purchase food-choice regret, one can expect that pre-purchase anticipated regret with respect to forgone (non-chosen) alternatives has an impact on consumer food choices, especially when the choice is considered to be important. The traditional Random Utility Maximization (RUM) models for discrete choices may not fully capture this impact. This study investigates the usefulness and potential in the food domain of a discrete choice model that follows the regret minimization principle, the Random Regret Minimization (RRM) model, as an alternative and complement to existing RUM models. The two models are applied to consumer stated choices of cheese in a choice experiment. The study also investigates whether and to what extent a number of personality traits determine whether particular consumers rather choose according to utility-maximization, or regret-minimization principles. Results show that at the aggregate level the two models have a similar goodness of fit to the data and prediction ability. Still, each of them shows better fit for particular subgroups of consumers, based on personality traits. Hence, the present study reveals a potential for the RRM model applications in the food domain, and adds to the empirical literature supporting previous findings on the RRM model found in other contexts. Further research is needed to explore in which situations and for which consumer segments the RRM model is the most useful model.

    Discounting and dynamic shelf life to reduce fresh food waste at retailers
    Buisman, M.E. ; Haijema, R. ; Bloemhof-Ruwaard, J.M. - \ 2019

    Consumer behaviour - Discounting - Dynamic shelf life - Food waste reduction - Perishable food product - Retail inventory management

    Approximately 89 million of tonnes of food is wasted every year in the EU along the whole food supply chain. The reasons for food waste by retailers include inappropriate quality control, overstocking and inaccurate forecasting. This study shows that food wasted by retailers can be reduced by discounting old products or by applying a dynamically adjustable expiration date (in other words dynamic shelf life (DSL)). We developed a simulation based optimization model to optimize the replenishment and discounting policy of a retailer who sells meat products. DSL outperforms a fixed shelf life (FSL) in terms of profit, waste, shortages and food safety. Furthermore, replenishment quantities can be higher. The benefits of DSL are greater when demand is low or when the shelf life of products is short. Discounting is a successful strategy to reduce food waste for both FSL and DSL. DSL without discounting is more effective than FSL with discounting. Combining DSL and discounting, allows for a further reduction of food waste.

    Measuring young consumers’ sustainable consumption behavior : development and validation of the YCSCB scale
    Fischer, Daniel ; Böhme, Tina ; Geiger, Sonja Maria - \ 2017

    Clothing - Consumer behaviour - Food - Measure - Sustainable consumption - Teenagers

    Purpose: Promoting sustainable consumption among young consumers has become a key priority on the research agenda in such different fields as education for sustainable development, environmental psychology and consumer policy. Progress in this field has been hampered by a lack of sophisticated research instruments capable of measuring consumption behaviors that are relevant both in terms of their sustainability impacts and their suitability for teenagers. This study aims to address this research gap and presents a scale for young consumers’ sustainable consumption behaviors (YCSCB) in the areas of food and clothing. Design/methodology/approach: The scale was developed in a two-step, mixed-methods approach. In an initial qualitative interview study, the actual behaviors of theoretically selected young consumers (n = 8) were identified with regard to acquiring, using and disposing of consumer goods in the areas of food and clothing. The YCSCB scale was constructed using the findings of this qualitative study and then validated in a subsequent quantitative study (n = 155). Findings: The YCSCB scale is a valid and reliable scale to measure young consumers’ sustainable consumption behavior in the areas of food (n = 14 items) and clothing (n = 13 items). Originality/value: The findings of this research provide a twofold contribution to advancing research on YCSCB. Firstly, it presents a consolidated scale that is explicitly constructed for teenagers and their consumption contexts. Secondly, it proposes a heuristic for developing more sophisticated measurements of SCB among young consumers that would allow a comparison between studies, is focused on behaviors (instead of confounding behaviors with intentions, attitudes or values) and is impact-oriented in terms of sustainability relevance.

    The role of health-related claims and symbols in consumer behaviour : The CLYMBOL project

    Consumer behaviour - Food choice - Food labelling - Health claims - Health symbols - Nutrition claims

    Health claims and symbols are a convenient tool when it comes to the marketing of foods and they should, in theory, support consumers in making informed food choices, ideally in choosing healthier food products. However, not much is known about their actual impact on consumer behaviour. CLYMBOL ("The Role of health-related CLaims and sYMBOLs in consumer behaviour") is an EU-funded project aiming to study how health claims and symbols influence consumer understanding, purchase and consumption behaviour. During a 4-year period, a wide range of research studies have been conducted across Europe, in order to analyse European consumer behaviour in the context of health claims and symbols. Results of the studies will provide a basis for recommendations for stakeholders such as policy makers, the food industry and consumer and patient organisations.

    Consuming apart, together : The role of multiple identities in sustainable behaviour

    Consumer behaviour - Cross-national survey - Environmental sustainability - Longitudinal - Social identity

    Although consumers' awareness of the environmental and ethical consequences of their behaviour has grown, research on the role of multiple consumer identities in sustainability behaviours is scarce. The aim of the current study was to explain sustainable behaviour from a social identity perspective. We conducted a longitudinal cross-national within-subjects design consumer study in six countries (T1, N=3083; T2, N=1440). The results indicate that environmental sustainability can comprise several distinct yet overlapping sustainable behaviours. Multiple social identities seem to play different roles in these different behaviours. Therefore, efforts to enhance different sustainability behaviours are challenging yet promising. Once consumers incorporate a sustainable behaviour, it becomes part of their own identity and could lead to spill over effects on other closely related sustainable behaviours.

    Consumer behaviour - Food choice - Food labelling - Health claim - Health symbols

    Health claims and symbols are potential aids to help consumers identify foods that are healthier options. However, little is known as to how health claims and symbols are used by consumers in real-world shopping situations, thus making the science-based formulation of new labelling policies and the evaluation of existing ones difficult. The objective of the European Union-funded project Role of health-relatedCLaimsandsYMBOLsin consumer behaviour (CLYMBOL) is to determine how health-related information provided through claims and symbols, in their context, can affect consumer understanding, purchase and consumption. To do this, a wide range of qualitative and quantitative consumer research methods are being used, including product sampling, sorting studies (i.e. how consumers categorise claims and symbols according to concepts such as familiarity and relevance), cross-country surveys, eye-tracking (i.e. what consumers look at and for how long), laboratory and in-store experiments, structured interviews, as well as analysis of population panel data. EU Member States differ with regard to their history of use and regulation of health claims and symbols prior to the harmonisation of 2006. Findings to date indicate the need for more structured and harmonised research on the effects of health claims and symbols on consumer behaviour, particularly taking into account country-wide differences and individual characteristics such as motivation and ability to process health-related information. Based on the studies within CLYMBOL, implications and recommendations for stakeholders such as policymakers will be provided.

    Understanding the purchasing behaviour of Taiwanese meat consumers in light of rising sustainability concerns
    Jen, Meng Yuan ; Wang, Shun Mei - \ 2015
    British Food Journal 117 (2015)5. - ISSN 0007-070X - p. 1474 - 1487.
    Asia - Consumer behaviour - Marketing communications - Sustainable consumption

    Purpose-The purpose of this paper is to provide an exploratory study of how Taiwanese consumer concerns about sustainability issues relating to pork are linked to their purchasing behaviours, using the case of “warm” meat. Design/methodology/approach-The study is based on qualitative semi-structured interviews of a cluster random sample of meat-purchasing consumers in Taiwan. The study data are analysed in light of grounded theory, to provide a clearer understanding of interviewees’ sustainability concerns arising from meat consumption. Findings-Results indicate that consumers do make meat-purchasing decisions based on to their sustainability concerns, and that there are a wide variety of such concerns, which can be broadly categorised as food security, animal welfare, and the environment. These implicate a variety of factors including ways of selling (e.g. fresh or frozen), the provision of information about production methods, certification, and traceability. By comparing consumers in supermarkets and traditional markets, the paper identifies divergent perspectives on food security in the context of local dining culture, and concludes that trust is a significant factor influencing purchasing behaviour. Originality/value-Prior research about consumers’ meat-purchasing habits and sustainability concerns is limited and de-contextualised. The present findings have implications for future communications to consumers, in that greater emphasis should be given to the local cultural contexts of food. It will be valuable to academics, livestock producers, consumer organisations, and policymakers interested in enhancing communication and trust between and among producers, consumers, retailers and government agencies.

    Animal products - Animal welfare - Consumer behaviour - Feeds - Foods - Research networks

    This review provides an overview of the main scientific outputs of a network (Action) supported by the European Cooperation in Science and Technology (COST) in the field of animal science, namely the COST Action Feed for Health (FA0802). The main aims of the COST Action Feed for Health (FA0802) were: to develop an integrated and collaborative network of research groups that focuses on the roles of feed and animal nutrition in improving animal wellbeing and also the quality, safety and wholesomeness of human foods of animal origin; to examine the consumer concerns and perceptions as regards livestock production systems. The COST Action Feed for Health has addressed these scientific topics during the last four years. From a practical point of view three main scientific fields of achievement can be identified: feed and animal nutrition; food of animal origin quality and functionality and consumers’ perceptions. Finally, the present paper has the scope to provide new ideas and solutions to a range of issues associated with the modern livestock production system.
