Widespread public opinion of food safety (POFS) has exacerbated consumer concerns about food safety and health, then driving consumers to purchase green food. However, the mechanisms at play in such concerns to consumer behaviour towards green food consumption have not explored, especially in the environment of social media. To fill up this gap, this research adopted a sequential two-stage mixed-methods approach to identify and examine the effects and mechanisms of public opinion of food safety on consumers' green food purchase intentions. In the initial qualitative research phase, the public comments on the microblogging platform was analyzed and we identified four top hot topics: public opinion of food safety, insecurity, green label trust (GLT) and green food purchase intentions (GFPI) based on text mining. In the quantitative phase of the survey-based research, we introduced the protection motivation theory and the hyper-attention cognitive model to construct a conceptual model. Based on this conceptual model, we conducted an empirical test with 1087 online questionnaires. The result showed that POFS had a significant positive effect on consumers' GFPI; consumer insecurity mediated the relationship between POFS and GFPI, and GLT played a moderating role between them. This study illustrates a psychological mechanism by which public opinion of food safety motivates consumers to switch to green food and provides new insights into green food consumption behaviour. It is an essential reference for encouraging green food consumption and promoting sustainability in the food industry.

The secondhand fashion market suffers from information asymmetry, creating consumer distrust and limited engagement in secondhand fashion (ESHF). The existing research on how sellers and product signals can mitigate this distrust is limited and produces conflicting results. This is particularly true in terms of understanding how signaling interacts with consumer-specific factors such as orientation and environmental awareness. Thus, this study contributes to understanding the factors driving consumer trust (CT) and ESHF through signaling theory and the nuanced role of consumer orientation and environmental awareness. Structural equation modeling, including multigroup analysis, is employed to test the proposed hypotheses with a sample of 203 Indonesian consumers from a secondhand market platform. The findings indicate that signals such as seller reputation, product history, and refurbishment details significantly enhance CT, with seller reputation being the most influential of the factors. The effectiveness of these signals varies by consumer orientation: functionality-oriented consumers respond more to remarketing information, whereas newness-conscious consumers are influenced more by refurbishment details. Additionally, consumer environmental awareness significantly strengthens the positive relationship between CT and ESHF, highlighting the importance of aligning environmental values with trust-building measures to enhance consumer ESHF. These insights enrich the theoretical understanding of signaling in secondhand markets and offer practical guidance for addressing the challenges associated with CT and ESHF.

The Sharing Economy has been suggested as a sustainable mode of consumption due to its potential to lower resource use and waste generation. A better understanding of sharing drivers, consumption dynamics, and their interlinkages is essential to suitably appraise the role that sharing practices can play in sustainable transitions. A survey of 654 participants from the EPFL (Ecole Polytechnique Fédérale de Lausanne; Switzerland) was carried out in order to investigate their household goods sharing practices. Among the participants, 328 people that borrowed household goods (takers) were identified and their responses were analysed to find motives and barriers for sharing household goods. Furthermore, Environmental Rebound Effects (EREs) were investigated with the consideration of psychological and economic factors that may influence them. The findings indicate that attitudes towards sharing household goods are most positively influenced by expected environmental impacts followed by enjoyment, economic savings, and social interactions. Negative influences include concerns about a potential loss of independence and lack of trust in people. However, it also turned out that EREs actually amounted to 102%, indicating that the motivating (direct) environmental benefits from sharing tend to be fully compensated for by the negative impacts derived from subsequent re-spending. The imperfect substitution of sharing and the moral licensing effect contributed to this result. Furthermore, consumers’ sharing rationale significantly influences the magnitude of EREs; either increased by economic motivations, or decreased by environmental motivations. Based on our results, we suggest that, to ensure the implementation of the Sharing Economy as a sustainable mode of consumption, it is necessary to increase awareness of the environmental rebound effects caused by re-spending. Consumers could thus be more motivated to share for environmental reasons, identify themselves with sustainability and decide to abstain from morally licensing themselves to re-spend their extra disposable income on Carbon Footprint intense activities.

Consumer product disposition is an area of research that needs particular attention to mitigate environmental pollution and natural resource conservation. Unlike product acquisition and consumption behaviour, consumer product disposition decisions and behaviour researches are limited. Few literature reviews are available to list several variables that impact the phenomena. However, these studies limit in following a logically structured framework to synthesise findings from existing studies. Therefore, this research study aims to review and exhaustively synthesise the findings from the past literature on consumer product disposition domain by following the theory-context-characteristics-methodology framework Accordingly, this study examines the development of consumer product disposition research over the years, journals of publications, focus areas of studies, authorship, theory used, context of the studies, predominantly used variables, and methodology used to conduct the research works. Further, based on the synthesis, a conceptual framework by integrating predominantly used antecedents, mediators, moderators, and consequences identified from the past literature also proposed. Finally, the future research directions based on theory, context, characteristics, and methodology were also discussed. This systematic review has various extensive implications for academia in expanding the existing knowledge base of consumer product disposition domain.

Consumers tend to perceive sustainable consumption as a complex and difficult to understand phenomenon. This particularly applies when being confronted with different forms of sustainable consumption. Therefore, we explore individual and joint facilitators and inhibitors of different forms of sustainable consumption, i.e., green buying, local buying, and environmental saving. Our online surveys conducted with consumers from Australia (n = 3561) and New Zealand (n = 2597) demonstrate that strong environmental attitudes increase green buying, local buying, and environmental savings, albeit to varying extents. Consumers' perceived financial ability is negatively associated with environmental savings and positively with the other forms. Additionally, environmental savings are negatively related to green buying. We identify further managerially relevant facilitators and inhibitors of sustainable consumption. Thus, we contribute to the literature by considering diverse forms of sustainable consumption and their tensions, and exploring the interplay of consumers’ environmental attitudes and perceived (rather than actual) financial ability.

The linear consumption model (take-make-dispose) has resulted in an abundance of pollution that has damaged living ecosystems and human health. The circular economy emerged as a potential tool to continue economic activities while generating less waste. Indonesian populations today majorly consist of millennials and members of generation Z (55.41%), and the consumption of these populations will shape Indonesia's future. This study aims to investigate the role of young consumers in green purchase behavior toward circular packaging in Indonesia by using Structural Equation Model (SEM). We have collected data from 287 respondents, and our results point to the positive and significant influence of green self-identity, environmental attitude, and socialization agents toward green purchase intention. Green purchase intention is also found to be a strong predictor of green purchasing behavior. This study presents practical implications for organizations as well as governments and NGOs.

The United Nation's Sustainable Development Goals (SDGs) prioritize halving global per capita food waste at retail, consumer, production, and food supply chain by 2030. This aligns with promoting circular economy principles for enhanced sustainability. The circular economy offers a transformative approach to the food industry by promoting environmental health, human well-being, and economic prosperity. This bibliometric analysis examines how circular economy principles can drive sustainability in food businesses, which closely aligning with SDGs 12.3 (food waste reduction), 12.5 (waste reduction), 13.2 (climate policy integration), and 13.3 (climate adaptation). Through a bibliometric analysis of 1000 relevant articles sourced from the Web of Science (spanning from 2005 to 2023), we evaluated the progress, challenges, and opportunities in this field. Utilizing analytical tools such as Biblioshiny (Bibliometrix) package of R-Studio and VOSviewer, the researchers identify key trends and research hotspots through thematic maps, co-occurrence networks, co-citation analysis, keyword analysis, and collaboration networks. This research highlights that the circular economy can transform the food industry by implementing sustainable waste management practices, optimizing supply chains and resource utilization to minimize environmental impact. Furthermore, research findings indicate that adopting circular economy principles in the food industry can significantly reduce waste and enhance resource efficiency by transforming food waste into valuable products such as biogas and bio-based materials. This study provides valuable insights for researchers, practitioners, policymakers, and government officials to improve sustainable food production systems. It enhances understanding in a vital area for guiding future endeavours to promote circular economy strategies for a more sustainable and efficient food industry.

Energy consumption is an important metric used to evaluate the sustainability potential of manufacturing processes. Due to the low volume and mass customization potential, additive manufacturing (AM) processes have experienced exponential growth in recent years, resulting in heightened ecological consciousness surrounding energy usage. Gaining insight into the energy-intensive sub-systems and sub-processes and identifying strategies for their minimization enables manufacturers to save on energy costs and also aids in reducing their carbon footprint. This study delves into the energy consumption characteristics of the powder bed fusion (PBF) process, particularly selective laser melting (SLM). Through experimental investigation, we investigate how certain factors impact energy usage, namely capacity utilization, layer thickness, and part orientation. We present a novel formulation for estimating primary and total energy consumption in PBF processes, offering a comprehensive energy consumption model. Our results demonstrate significant energy savings with increased capacity utilization—up to a 32.68% reduction in total energy consumption (TEC) per part. Layer thickness variations show the lowest TEC at 25 μm, which can be attributed to the SLM machine's reduced operational time and energy usage of auxiliary components. Furthermore, altering part orientation for the given case study yielded a 50% reduction in TEC, highlighting orientation as a critical factor in energy efficiency. Our formulation, benchmarked against experimental data and specific energy consumption (SEC) values from the literature, effectively captures these parameters' influence on energy usage. The insights from this research advance our understanding of energy dynamics in SLM processes and pave the way for more energy-efficient practices in AM.

In Japan, households are required to save more electricity in response to electricity supply shortages after the Great East Japan Earthquake and meet the 66% greenhouse gas reduction target in the residential sector under the Paris Agreement. This study examines the effects of providing information to promote the implementation of green curtains, a summer electricity-saving behavior at home, using a randomized controlled trial for residents in Japan. Green curtains are made by growing annual vines, like curtains on a net stretched across a window or wall, and have the effect of reducing room temperature by providing shade. Based on their characteristics, being visible to others and a low implementation rate, we examine the effects of the perceptions and cognitions of the implementation of green curtains in the city (subjective descriptive norm) and the information provided on the trends in green curtain implementation in neighboring districts (objective descriptive norm) on the respondents' willingness to implement. The results show that subjective descriptive norms influence the willingness to implement. Further, the information about neighboring districts with slightly higher green curtain implementation rates is more effective than information about neighboring districts with significantly higher rates. This examination of the comprehensive influence of descriptive norms and the effect of the dynamic and relatively comparative forms of providing descriptive norm information have implications for studies in other fields on promoting prosocial behaviors visible to others and with low implementation rates.

Reducing the current level of meat consumption would reap significant environmental benefits. However, a consumer transition towards more plant-rich eating is lagging, and the social sciences have had limited success in understanding behavioural change in this area. Here, we advocate a research agenda focussing on the role social networks could play in encouraging consumers to eat less meat. We present main research directions in social network theory and highlight the distinction between simple and complex behavioural domains of which food and eating practices are an example of the latter. To illustrate one way in which social network insights can contribute to meat reduction research, we then present results from a questionnaire-based study of Danish consumers. We examine the association between an individual's personal network and reduced meat consumption. In line with assumptions, we show that, for a complex domain such as food and eating practices, exposure from multiple network sources is central to behavioural adoption. However, multiple network exposure is predominantly important for the initial decision to eat less meat. A narrower network of personal contacts become more central during the implementation stage. We end by outlining future research directions for social network research regarding meat reduction.
