Growing environmental concerns have intensified interest in sustainable packaging; however, consumer adoption of beverages with environmentally friendly packaging remains relatively low in developing markets. This study investigates the determinants of consumers’ purchase intentions toward such beverages in Central Vietnam using the extended Theory of Planned Behaviour (TPB), integrated with the Stimulus–Organism–Response (S-O-R) framework. Data were collected from 475 consumers and analysed using structural equation modelling (SEM). The results indicate low consumer familiarity with eco-friendly packaging labels, such as the Forest Stewardship Council (FSC), Green Dot Logo, and Compostable Logos, and only moderate adoption of sustainable packaging materials, with particularly low willingness to purchase beverages in fully recycled packaging. SEM findings show that attitude, perceived behavioural control, and perceived consumer effectiveness are significant direct predictors of purchase intention. Subjective norms and perceived environmental packaging knowledge show positive but marginal direct effects, whereas packaging functions have no significant direct effect. Attitude and perceived behavioural control act as key mediators. The study highlights the need to strengthen consumer awareness, improve recognition of eco-labels, and enhance social and psychological support to promote the adoption of environmentally friendly beverage packaging.

This study investigates asymmetric consumer responses to recycled thermoplastics, with a focus on the roles of eco-consciousness, sustainability knowledge, perceived concerns, trust, and value congruence. Using survey data from Hungarian consumers, the study applies linear and binary logistic regression analyses to examine how these factors influence brand perception, willingness to pay, and communication preferences. The results show that economic concerns act as a dominant barrier, significantly reducing both brand evaluations and willingness to pay, while functional concerns play a more limited role. Trust in sustainability communication and positive brand perception emerge as strong predictors of willingness to pay, with brand perception showing a stronger effect. Eco-consciousness consistently influences consumer responses, whereas sustainability knowledge demonstrates more selective and context-dependent effects. In addition, consumers show a clear preference for credible, evidence-based communication, while informal and promotional signals are less effective. Overall, the findings highlight the importance of reducing perceived risk, strengthening brand perception, and aligning sustainability communication with consumer expectations to support the adoption of recycled thermoplastics in the automotive industry.

Extended producer responsibility (EPR) is intended to link producer design decisions to end-of-life costs, but collective EPR schemes typically weaken this link by routing funding through producer responsibility organisations. We develop a multi-level framework of consumer-integrated environmental protection (CIEP) and argue that individual producer responsibility (IPR), where producers bear product-specific end-of-life liability, can function as a governance mechanism that reconnects design, consumer behaviour and waste governance. This paper is a qualitative multiple-case research study—not a systematic review—which draws on three funded research projects: (i) small and medium-sized enterprise (SME) tools for design-for-recyclability, (ii) an artificial intelligence (AI) application for household waste sorting, and (iii) closed-loop recycling of fishing gear in Vietnam. Within the first project (ToCoReRaM), a PRISMA-based systematic review of web-accessible circular economy tools finds that only 2 of 23 tools are SME-accessible through standard web searches. The AI-based waste-sorting application achieves approximately 75% classification accuracy under real-world conditions. The fishing gear study demonstrates technical and economic viability of closed-loop recycling, and a survey of more than 1500 Vietnamese fishers finds 95.8% willingness to return used gear given appropriate incentives. Together, the cases show that effective circular governance requires four complementary elements: IPR-based producer accountability, SME-accessible design tools, digital consumer guidance at the point of disposal, and context-sensitive governance capacity. These findings inform policy pathways for Sustainable Development Goal (SDG) 12 and SDG 14. Full article

Integrating sustainability into luxury products poses fundamental challenges when brands introduce alternative materials made from recycled content that lack the intrinsic value of precious metals. This study investigates consumer perceptions and willingness to pay more for luxury jewelry made from alternative recycled materials among 357 consumers in the Bangkok Metropolitan Region. The conceptual framework examined five value dimensions (self-expression value, aesthetic value, social value, perceived natural rarity, and perceived sustainability) with pro-environmental self-identity as a moderating variable. The model explains 59.2% of the variance in willingness to pay more. Results confirm significant effects of all five dimensions, with aesthetic value as the strongest predictor. Pro-environmental self-identity significantly moderates the relationship between perceived sustainability and willingness to pay more. Despite high levels of sustainability awareness, the results reveal an attitude–behavior gap: environmental concern does not automatically translate into greater spending on sustainable luxury jewelry. This research contributes to the literature on sustainable luxury consumption by clarifying the relative importance of value dimensions and highlighting the conditional role of consumer identity in shaping the acceptance of price premiums.

In response to mounting resource and environmental pressures in the textile industry, this study investigates the feasibility of fiber-to-fiber closed-loop recycling for used firefighting protective clothing—a waste stream characterized by material homogeneity and large-scale disposal. Employing a mixed-methods approach combining stakeholder questionnaires, field investigations (n = 3650), and performance testing of retired aramid fabrics, this research systematically evaluates the technical, market, and systemic potential for circular regeneration. Results demonstrate strong multi-stakeholder support (over 89%) and significant consumer willingness to purchase recycled products (81.01–84% across categories), while material tests confirm the retained flame resistance and mechanical properties of the fabrics, enabling high-value applications. By constructing an integrated framework spanning technical, policy, market, and cultural dimensions, and proposing strategies of “targeted recycling” and “value reconstruction,” this work confirms the commercial viability and environmental benefit of recycling firefighting gear. It further offers a transferable model for advancing the circularity of other safety and protective textiles, with key innovations lying in its comprehensive full-chain assessment and the concurrent validation of stakeholder dynamics and material performance.

The increasing environmental concerns of plastic waste have encouraged more interest in environmentally friendly packaging, but consumer willingness to pay (WTP) for green alternatives in emerging markets such as Saudi Arabia is not fully explored. This research explores the relationship between awareness of sustainability and price sensitivity in determining WTP for green packaging in the Saudi retail market. The study utilizing a mixed method included both a Contingent Valuation Method (CVM) and a Discrete Choice Modeling (DCM). In it, data was gathered and analyzed using a sample of 424 urban consumers in Saudi Arabia’s major cities. The findings of OLS regression indicated awareness of sustainability had a significant, positive effect on WTP, whereas price sensitivity had a negative effect. There was a marginal interaction effect indicating that awareness could overcome price aversion. Logistic regression supported awareness as a dominant factor in binary product choice, although price sensitivity was not significant in the said model. The multinomial logit model also showed that the type of package, environmental labels (more so the “100% recyclable” type), and price had significant effects on consumer preferences. These results indicate that there is acceptance of sustainable packaging by consumers in Saudi Arabia if the product is communicated effectively and priced competitively. Full article

Climate changes have increased interest in the circular economy, an alternative model that seeks to minimize environmental impact and maximize resource reuse. A key element of this model is individuals’ behaviors and attitudes, which determine the overall efficiency of recycling processes. The study fills the gap by investigating how selected socio-demographic factors affect attitudes and intentions toward recycling and material reuse in the Slovak Republic, by using the Perceived Characteristics of Innovating (PCI) framework. Through a two-way ANOVA, we tested the hypotheses that higher education correlates with stronger recycling attitudes and that women are more willing than men to engage in circular practices. The results show that gender differences in consumer attitudes towards the circular economy do occur, but their magnitude is often conditioned by education level. Education proved to be the strongest predictor of ecological behavior: respondents with higher education reported stronger beliefs in the importance of recycling and a greater willingness to act sustainably. The interaction between gender and education revealed that university-educated women hold the most pronounced pro-environmental attitudes, underscoring the importance of gender-sensitive educational strategies. It is recommended that environmental education and outreach focus on less-educated groups, particularly women, who have high potential to influence their communities. Full article

In recent years, the rapid development of the agricultural product e-commerce and logistics industry has generated a large amount of express packaging waste. The way in which to promote the reuse of express packaging and reduce carbon emissions has become an important issue, and the current research on consumers’ willingness to express packaging recycling is still in its infancy. This study, based on the theory of Extended Planned Behavior, constructed a factor model observing the influence of consumers’ willingness to participate in the e-commerce of agricultural products’ recyclable packaging recovery. Using partial least squares structural equation modeling to process and analyze 659 questionnaire data, the results show that policy promotion and perceived benefits had the highest degree of positive influence on recycling willingness, and there was a relatively weak positive effect of packaging performance and subjective norm on consumers’ willingness to recycle in terms of packaging performance and the subject norm of recycling willingness. The attitude towards recycling had the smallest impact on the willingness to recycle. Therefore, in order to promote the production and use of recyclable packaging, government policies should be strengthened, and consumers’ perceived benefits and subjective norm should be improved, as well as the packaging performance of recyclable packaging. This study provides new insights into Chinese consumers’ participation in the recycling and promotion of recyclable packaging for e-commerce agricultural products. Full article

This study investigates a two-stage production–inventory model with subsidy policies for paper cup recycling. The model includes remanufacturers, recyclers, and consumers, taking into account their preferences for different recycling channels. The negative binomial distribution of investment fund w is introduced and briefly studied. The influence of various subsidy strategies on the optimal pricing, profit, and recycling volume of the reverse supply chain is discussed. Numerical simulations show that increased consumer recycling preferences positively impact the recycling volume and profit. When subsidies are limited, subsidizing remanufacturers leads to higher recycling volumes, while subsidizing consumers results in higher profits at lower-to-middle subsidy levels. The findings suggest that policymakers can leverage different subsidy strategies to effectively manage the paper cup recycling supply chain and promote sustainability by incentivizing key stakeholders to participate in the recycling process. For example, subsidizing remanufacturers can increase the overall recycling volume by making it more financially viable for them to collect and process used cups, while subsidizing consumers can boost their participation and willingness to properly dispose of cups for recycling, leading to higher profits for the reverse supply chain.

The cosmetics industry requires a long-term, sustainable vision to reduce its impact on the environment. Within this process, packaging is of critical relevance, as it impacts the ecological footprint of products and determines consumers’ perception of the product as sustainable and green while shaping their willingness to purchase the product. This article implements a mixed-methods design to combine theoretical insights with the opinions of experts and the perceptions of consumers. It elicits which packaging elements are the most important in determining consumers’ willingness to pay for green cosmetics and which are the most important regarding their perception of the product being sustainable and green. The results of the conjoint analysis-based study conducted in Germany indicate the predominance of the used materials for packaging over other characteristics (glass +EUR 1, bio-based materials +EUR 0.92, recycled plastic +EUR 0.75 vs. wood as base category). Labels (Veganblume +EUR 0.68, Cruelty-Free +EUR 0.11) and the availability of refill options (+EUR 0.61) score in second place, while coloring (black −EUR 0.2, green −EUR 0.11, brown −EUR 0.13 vs. white as the base category) and QR codes (+EUR 0.13) score last regarding participants’ willingness to purchase the product. The results also reveal a distinct difference between the order of attributes driving the willingness to pay and those driving the perception of the sustainability of a product. Regarding sustainability perception, the relevance of labels and color increases distinctly, while package material remains the dominant attribute. Full article

The volume of food waste is increasing, and research has highlighted the issues related to its disposal methods. Disposers are emerging as a solution for food waste recycling; they are already used in various countries. Only a limited portion of solid waste discharge has been permitted depending on the infrastructure capacity. Although additional administrative costs are required to adapt the existing food waste disposal system to include disposers, research on consumers’ willingness to pay (WTP) for such changes is lacking. Therefore, this study analyzes consumer WTP to increase the capacity of infrastructure. In this study, contingent valuation methods are employed to evaluate WTP, and data are collected based on a one-and-one-half-bounded dichotomous choice model with 1155 residents. In addition, this study considers the relevant knowledge, satisfaction, and expectations of the service. The results show that the average WTP for additional sewage rates is KRW 6860 (USD 5.2). Covariate models show that knowledge of water quality and awareness of the extent of untreated sewage discharge during rainfall in CSOs significantly influence WTP. Additionally, satisfaction with sewage odor, expectations regarding sewerage fees, and concerns about preventing sewer backflow impact WTP. However, satisfaction with the disposer does not significantly affect WTP. Additionally, a regional analysis is conducted to determine the priority of regional infrastructure improvements. In Incheon and Seoul, where the number of complaints was higher than the average, WTP showed a positive influence. The findings of this study have practical implications for policymakers, as they can be used to determine regional policy priorities. Full article

The development of the construction industry has generated a large amount of construction waste, and resource utilization of construction waste is an effective means of recycling. However, such recycled construction waste products still lack market competitiveness and recognition. Consumers’ psychological activities are often influenced by emotions, and the sense of awe plays an important role in green consumption. This study aims to investigate how the sense of awe affects consumers’ willingness to pay for construction waste recycled products. The study used functional near-infrared spectroscopy (fNIRS) with a willingness-to-pay task paradigm for experiments, which aims to reveal how different types of awe affect willingness to pay for construction waste recycled products. The behavioral results showed that two conditions effectively induced awe and enhanced consumers’ willingness to pay, but the difference between nature awe and social awe was not significant. The neural activation results showed significant activation in the inferior prefrontal gyrus and dorsolateral prefrontal cortex. In particular, dorsolateral prefrontal cortex activity was significantly enhanced in the social awe condition. The functional connectivity results showed that, compared to the control condition experiment, the awe condition experiment triggered stronger functional connectivity. Therefore, exploring the effect of awe on the willingness to pay for construction waste recycled products can provide a basis reference for companies to develop marketing strategies and corporate pricing and promote the promotion and application of construction waste recycled products in the market.

This study investigates the factors influencing consumers’ willingness to purchase recycled and secondhand clothing as part of sustainable fashion. Using a model constructed with six latent variables—environmental consciousness, perceived value, interest in fashion, social media use, uniqueness, and purchase intention—data were gathered through an online survey targeting Japanese consumers. The findings reveal that consumer perceptions of social responsibility and environmental values significantly impact their purchasing intentions. Uniqueness plays a key role in shaping purchase decisions for secondhand clothing, while it has no significant effect on recycled clothing, emphasizing the need for tailored marketing strategies. This study offers a comprehensive examination of consumer behavior in the sustainable fashion industry, providing crucial insights for the development of segmented marketing strategies that cater to the distinct motivations and preferences of consumers.

Environmental awareness and behavior play a crucial role in the improvement of the environment. Five dimensions of environmental awareness are considered here including environmental values, environmental knowledge, environmental responsibility, environmental ability and environmental concern while we also distinguish between private and public environmental behaviors. Based on data from the China General Social Survey (CGSS) in 2003, 2010 and 2021, this research investigated changes in Chinese residents’ environmental awareness and environmental behavior and the relationship between them. The relevant empirical methods were the MV-Probit model, the Poisson model and a mediating effect model. The results are as follows: (1) From 2003 to 2021, environmental awareness of the public has improved significantly. Among them, environmental values, environmental knowledge and environmental concern have increased by 24.5%, 12.6% and 12.77%, respectively, while environmental capacity has decreased by 7.27% from 2010 to 2021. The eastern region of China has the highest score of environmental awareness, while the western region has the lowest one. (2) From 2003 to 2021, the public’s green consumption behavior changed from more than half of the public never consuming green products in 2003 to nearly 75% always or often consuming green products in 2021. Increases in recycling were also found over time. However, the participation rate in public environmental behavior declined. In 2021, environmental behaviors were lowest in the eastern region and highest in the western region. (3) Environmental responsibility, environmental concern and environmental capacity direct and indirectly affect private and public environmental behaviors and the number of environmental behaviors through the willingness to protect the environment, which plays a semi-mediating role. Environmental knowledge only has a direct impact on private green consumption behavior. (4) There is a correlation between public and private environmental behaviors. Given the results of this study, a series of policy implications and recommendations are provided. Full article

In recent years, there has been a shift toward sustainability in several aspects of our lives, including food packaging. In line with a circular economy model, several organizations are adopting industrial reusable solutions for food packaging, which are designed to be used multiple times throughout their life cycle. Despite an overall positive impression, many consumers lack clarity on reusable food packaging, with concerns regarding safety and cost, for example, that affect the actual adoption of reusable packaging. This study aimed to assess the impact of information regarding specific characteristics of reuse that could encourage consumers to choose reusable packaging over other sustainable (compostable and recyclable) alternatives when purchasing agrifoods. Through an online survey involving 104 participants, the study compared preferences and willingness to pay for reusable packaging while delivering (or not delivering) information as to the safety and production costs of reusable packaging. Information concerning the safety of reusable packaging, but not that regarding production costs, increased consumers’ preferences for reusable packaging. At the same time, willingness to pay was not affected by either type of information. These results highlight the crucial role that delivering appropriate information plays in addressing consumers’ psychological concerns and in fostering the acceptance of reusable packaging when purchasing agrifoods.
