This study addresses the challenge of electric vehicle power battery recycling by proposing a dynamic deposit-refund system (DRS) under the Extended Producer Responsibility (EPR) framework, as an alternative to the conventional static DRS. An evolutionary game model is developed to capture the strategic interactions between local governments and responsible enterprises, incorporating a feedback mechanism where the deposit level is dynamically adjusted based on corporate EPR fulfillment rates. Using system dynamics simulation, the evolutionary paths under both static and dynamic DRS regimes are compared. The results demonstrate that the dynamic DRS effectively eliminates persistent oscillations and guides the system toward a stable equilibrium. Furthermore, by defining an ideal scenario, key factors are identified and prioritized to assist the government in steering the system toward this desired state. These findings offer actionable insights for designing adaptive regulatory mechanisms and fostering a self-sustaining battery recycling ecosystem. Full article

Deposit Refund Systems (DRS) are widely adopted in many European countries as effective mechanisms for increasing recycling rates and promoting circular-economy practices. Greece is currently preparing for the introduction of a national DRS for beverage containers, a transition expected to reshape existing waste-management structures. This study investigates the systemic challenges that may hinder the successful implementation of the upcoming Greek DRS. Focusing exclusively on polyethylene terephthalate (PET), aluminum, and glass beverage containers, this study adopts a multi-stakeholder qualitative approach involving 28 semi-structured interviews with beverage producers, retailers, recyclers, logistics actors, consumer representatives, and regulatory authorities. Thematic analysis reveals four interdependent barriers: restricted consumer accessibility due to uneven distribution of return infrastructure; fragmented governance and unclear institutional responsibilities; weak coordination and operational misalignment among supply-chain actors; and low consumer participation shaped by behavioral and cultural factors. These findings underscore that Greece’s DRS readiness is constrained not by technological limitations but by systemic gaps in governance, infrastructure planning, and stakeholder collaboration. This study contributes to the DRS literature by providing one of the first pre-implementation, multi-actor assessments in a Southern European context and offers policy-relevant insights to support an effective, equitable, and transparent rollout of the national DRS.

With the booming development of the new energy vehicle (NEV) industry, the issue of power battery recycling has increasingly attracted attention. Standardized recycling of power batteries can reduce environmental pollution and promote sustainable resource utilization. This paper employs evolutionary game theory to construct two models of deposit systems for the recycling of new energy vehicle power batteries: one under market mechanisms and the other with government participation. The evolutionary stable strategies among vehicle manufacturers, consumers, and the government are examined, and the stable equilibrium points of the models are analyzed. Finally, Matlab is used to conduct a simulation analysis of the deposit system with government participation. The results indicate that the deposit system under market mechanisms is difficult to constrain consumer behavior, while the deposit system with government participation is conducive to promoting the achievement of long-term environmental protection goals. These findings provide valuable insights for policymakers in designing deposit–refund systems and contribute to advancing the sustainable development of the NEV industry. Full article

This article discusses key aspects of deposit–refund system design in Poland, highlighting the importance of energy-sustainable collection logistics. The main role in this system is played by the operator responsible for collecting and transporting packaging to metering centers and recycling plants. The research focused on the optimal placement of logistics facilities to minimize energy expenditures, using the balanced center of gravity method. It took into account the distribution of collection points and the intensity of material flows to develop an efficient and environmentally friendly reverse logistics model. The most important results of the research are the development of a model for the layout of logistics facilities that minimizes energy consumption, the identification of key factors such as the location of collection points and material flows, the development of a methodology for green logistics, and practical recommendations for system designers. The proposed solutions, although innovative in Poland, are universal in nature and can be applied in other countries. The article makes an important contribution to the development of sustainable bail logistics and promotes a balanced energy transition. Full article

The purpose of this research is to develop an advanced model to serve as a strategic tool for the Thailand government in managing the country and to propose ways for the government to exercise state power through proactive measures to address governance gaps and ensure long-term sustainability. This research employs a mixed-methods approach. The research methodology involved the following stages: (1) Quantitative research was conducted by creating the best model, which involved conducting path analysis based on an autoregressive integrated moving average with an exogenous variable model (PAARIMAX (1,1,1)). (2) The results of the quantitative research were optimized to facilitate additional qualitative research in order to identify appropriate ways of using state power for long-term sustainability in country management. The study’s findings suggest that the government will need to exercise its state power in the governance of the country through the development of a long-term national management plan (2024–2043). This plan involves the establishment of a new scenario policy wherein a minimum of 35% clean technology and green materials must be utilized within the economic sector. This is primarily due to their significant impact on environmental change. Furthermore, the government should exercise its state power to mandate an immediate reduction in energy consumption of 50%, achieved through the immediate adoption of renewable energy sources. This research utilized the results derived from the PAARIMAX model to conduct further qualitative analysis to fill the gaps, enhance the value of the quantitative research, and align it more effectively with the context of practical application. The study found that the proactive measures suggested by stakeholders must be implemented alongside the urgent establishment of new scenario policies, including for charges and taxes, subsidies and concession taxes, deposit refund systems, and property rights and market creation.

The circular economy (CE) poses major challenges to the citizens of European countries. Proper waste management is a priority here. Poland is one of the countries that has been trying for many years to meet the requirements to achieve an appropriate level of recovery as well as the recycling of municipal and packaging waste. In order to achieve appropriate levels of packaging waste recycling, it was planned to implement an otherwise refundable deposit system starting in January 2023. Currently, work is still underway to implement this system starting in January 2025. The aim of the study is to describe the current work of the ministry, entrepreneurs and recovery organizations in this area and, on this basis, to indicate the barriers and uncertainties encountered in the implementation of this system. The authors want to answer the question of what barriers and benefits can be expected after the implementation of the deposit system. The implementation of the system has been postponed many times (for several years). The current involvement of various organizations (large cities, chain stores and recovery organizations) indicates that the system will be implemented on 1 January 2025. Based on the example of other EU countries, what estimated benefits can be expected after implementing the system in Poland? An extensive literature review and survey research indicate that Polish society views the deposit system favorably and Poland is ready to implement it. Specific regulations from the Minister of Climate and Environment need to be implemented as well as special machine need to be put in stores to start the deposit system. Examples of ongoing efforts to create appropriate infrastructure also show that Poland is on track to join the deposit system from January 2025. The deposit system will be continuously improved and expanded with more packages. Currently, it is planned to be introduced only for selected packages. Full article

This paper provides a comprehensive evaluation of the environmental impact of implementing the beverage container deposit refund system on marine and coastal litter along the Latvian coastline. It incorporates data and insights from the assessment of deposit fractions littered in coastal areas during the post-season autumn period (weeks 3–4 in October and week 1 in November) in three monitoring sessions from 2021 (before the introduction of the DRS in Latvia) to 2023 (post-introduction). In 2022, a 43% overall decrease in selected public coastal areas was observed, with significant reductions at 11 out of 17 sites. This positive trend continued in 2023, showcasing a further 22% decrease compared to 2022 and a substantial 56% decrease compared to 2021. This study delves into the specific impact on different material types of beverage containers, reporting significant decreases in plastic and aluminium litter fractions. While glass beverage container litter showed a smaller decrease, overall positive trends continued in 2023. However, the situation with aluminium cans remained challenging, especially in border areas with Lithuania and Estonia. This study emphasizes that beverage containers with identifiable deposit system labels constitute a minority of the total litter pressure, underscoring the need for ongoing efforts to address containers without deposit labels, particularly in specific border areas. The findings provide valuable insights into the effectiveness of the deposit system in mitigating coastal litter, contributing to sustainable waste management practices in Latvia. Full article

Recycling waste electrical and electronic equipment (WEEE) has garnered considerable societal attention. To incentivize WEEE recycling within a closed-loop supply chain (CLSC), a deposit-refund system (DRS) has been implemented. This study delves into the implications of a market-driven DRS on WEEE recycling under different recycling models. A Stackelberg game analysis is employed, where an electronics manufacturer (leader) has sufficient channel power over an electronics retailer and a third-party recycler (followers). The results indicate that the market-driven DRS significantly incentivizes consumer recycling efforts, ultimately elevating the economic efficiency of the supply chain. When the electronics manufacturer assumes responsibility for WEEE recycling, it streamlines the recycling process, thereby enhancing operational efficiency and profitability. Conversely, when the electronics retailer handles WEEE recycling, it reduces retail prices and simplifies the recycling process, positively influencing consumer purchasing behavior. However, when a third-party recycler undertakes WEEE recycling, the recycling volume tends to be minimal, resulting in the lowest level of supply chain profits. This paper provides theoretical and practical implications for improving the recycling effectiveness and operational efficiency of the CLSC. Full article

Water bottles are widely used in the Gulf countries. One estimate indicates that the water bottle usage in the United Arab Emirates (UAE) may reach up to 250 L of water per person annually. Generally, the water bottles are made of polyethylene terephthalate (PET), a recyclable material. Because of the non-availability of a powerful incentive system, these recyclable water bottles are often disposed of in landfills. This paper proposes a feasibility study of building a Deposit–Refund System (DRS) to encourage the closed-loop recycling of 0.5 L PET water bottles in the UAE waste disposal system. Water bottles are collected by a reverse vending machine (RVM) and recycled to produce PET bottles, and the proposed system will reward consumers with 0.04 United Arab Emirates Dirham (AED) per deposited water bottle. Additionally, this study calculates the cost of 100% virgin polyethylene terephthalate (vPET) and 60% recycled polyethylene terephthalate (rPET) bottles based on the UAE population, data obtained from local water bottle companies, and existing research. Adopting this DRS will cut down on waste, protect the environment, improve the manufacturing process of water bottles, and boost the local economy. Full article

This study analyzes consumers’ perceptions of the Deposit Refund System (DRS) initiative in Greece. It aims firstly to measure the effectiveness of these systems in Greece. Secondly, based on elements from the Theory of Green Purchased Behavior, it identifies the motives of DRS users and how they affect DRS usage and perception. Data were gathered using a mail-out survey to consumers in various cities in Greece. The key finding supports the argument that moral motives significantly lower the costs associated with household recycling efforts. Moreover, Structural Equation Modeling (SEM) is used to examine the research hypotheses. The findings reveal that the DRS motives positively and statistically significantly affect the process of recycling and user perception of DRS. Moreover, the DRS perception affects the adoption of the DRS and complementary mediates the effect of motives for DRS adoption. The normalized model shows that an increase in motives by 1 unit will increase the perception of consumers for refundable recycling by 0.346 units. Similarly, an increase in the motives by 1 unit will increase the use of refundable recycling by 0.296 units. Full article

The steadily increasing amount of waste requires new strategies for package waste reduction. One strategy is to switch from single-use plastic packaging to glass packaging; however, this strategy is only beneficial from an environmental perspective when complemented with a multi-use deposit refund system with standardized glass containers. This implies the loss of package shape as a differentiation criterion, which has been considered a highly relevant marketing instrument in the fast-moving consumer goods markets. Against this background, the current research investigates in an online experiment the suitability of anthropomorphized label designs on prompting purchase intentions in the context of reusable glass jars. The study further investigates the mediating roles of brand attitude and brand interest. Contrary to the postulated hypotheses, anthropomorphized labels negatively impact brand attitude, and the sequential mediation of anthropomorphism on brand interest and brand attitude on purchase intention was significant. Our findings reveal that anthropomorphized labels stimulate brand interest, which in turn positively affects purchase intention. The results emphasize the relevance of brand interest in package design and guides manufacturers, brand managers, and policymakers to effective differentiation strategies for standardized multi-use packages.

The research subject is the deposit-refund system of beverage packaging (PET, glass and aluminium) in Hungary, which is under development. For the success of the planned system, it is important to consider the population’s opinion. Therefore, data from a primary questionnaire survey were used for the analyses. This questionnaire was conducted in 2020 and resulted in an evaluable sample of 20,430 people. The study aims to answer the following research questions (Q). Q1. Does the reform of the beverage packaging deposit-refund system in Hungary have a raison d’être? Q2. What are the demographic characteristics (gender, type of residence, qualification) of those who would redeem beverage packaging in their households if the state paid for it? Q3. Do the demographic characteristics and/or the environmental attitudes of individuals significantly influence their perceptions of the planned new system, and how strong is the relationship between them? As for the method for answering the research questions, descriptive statistics and relationship analyses (Cramer’s V and Kendall’s tau) were applied to the closed answers. The results show that the analysis of the primary research provides well-determined directions for legislators and decision makers who develop the detailed operating rules of the new system.

Festivals generate huge amounts of waste during a short period of time, usually in three to four days. Single-use packaging is one of the dominant waste streams at the festivals. In order to minimize single-use plastic packaging waste generation and negative impacts on the environment, outdoor festivals apply alternative reusable cup systems and strategies. However, little studies have been made on how different reusable beverage cup reuse models can affect material circularity within certain festivals, and how it contributes to cup damage and loss. This article presents the results of a pilot study of different reusable cup reuse models within seven Lithuanian summer outdoor festivals. Three different models were applied and tested: A—only reusable cups, non-refundable model; B—only reusable cups, with deposit-refund; C—a mixed system of reusable cups with deposit-refund and of single-use cups. Material flow analysis (MFA) was performed, and the Materials Circularity Indicator (MCI), developed by Ellen MacArthur Foundation, was calculated to study the applied models. According to the findings, refund models (B, C models) have lower rates of damaged and lost cups compared to non-refundable reusable cup reuse model (A model). This paper shows that different reuse models provide different damage, loss and return rates of reusable cups. The data presented can aid decision-makers who need to choose a reuse model for a certain event. Full article

Theoretical and empirical studies have generally weighed the effect of peer punishment and pool punishment for sanctioning free riders separately. However, these sanctioning mechanisms often pose a puzzling tradeoff between efficiency and stability in detecting and punishing free riders. Here, we combine the key aspects of these qualitatively different mechanisms in terms of evolutionary game theory. Based on the dilemmatic donation game, we introduce a strategy of commitment to both cooperation and peer punishment. To make the commitment credible, we assume that those willing to commit have to make a certain deposit. The deposit will be refunded as long as the committers faithfully cooperate in the donation game and punish free riders and non-committers. It turns out that the deposit-based commitment offers both the efficiency of peer punishment and the stability of pool punishment and that the replicator dynamics lead to transitions of different systems: pool punishment to commitment to peer punishment.
