The circular economy is becoming a globalised phenomenon, but the regional emergence of circular business models differs significantly. By adopting a circular business institutionalisation perspective which bridges theory on institutional work and “ecologies of business models” we study the emergence of circular business models in Japan, a region with recent circular policy and business commitment, through a study of 13 companies who implemented circular business models. The research finds that slow- and close-the-loop circular strategies dominate. Innovations focus on circular design, value chains, rental, lease & sharing, paying per use/performance, buy & take back, remanufacturing and recycling. Interviewed organisations modify existing business models, create entirely new ones, and disrupt existing business models. We coin “collective institutional work”: an approach that reflects stakeholder engaged strategies in Japan. The circular business institutionalisation perspective can inspire comparative research to better understand the emergence of circular business models in various regional contexts.

Digital product passports (DPP) aim to provide comprehensive information on products throughout their lifecycle, improving decision-making in Circular Economy (CE) strategies. Although Eco-design for Sustainable Products Regulation (ESPR) has outlined requirements for information, technical designs, and operation of DPPs, it does not specify the types of information required at each lifecycle stage or the solution components, which can impact DPP development. To address this knowledge gap, we conducted a systematic literature review and examined 25 DPP frameworks across different industries, focusing on four main areas: data carrier, data source, data security, and user access and verification. Findings show that QR codes and RFID tags are commonly used data carriers in the manufacturing and construction industries, and Blockchain technology is the most widely adopted solution for data security. Furthermore, we sorted the types, and suggested information stored in DPPs into four stages of the lifecycle. Our review highlights a lack of efforts to enable information updates during maintenance by third-party service providers in the product use phase after the DPP has been launched. In response, we propose a conceptual blockchain-based DPP framework that supports a dynamic information flow, allowing verified users (e.g., repairers) to update DPPs with necessary lifecycle information (e.g., maintenance details). Implications such as the security of data carrier and identifying critical data for DPP to avoid information overload need to be considered. Advancing DPP with artificial intelligence tools should be explored to predict and estimate the product health to enhance longevity.

Absolute environmental sustainability assessments quantify the environmental impacts of human activities in relation to ecological carrying capacities. Such assessments necessitate the application of sharing principles to allocate shares of carrying capacity to actors and activities at different scales, including products, companies, sectors, and countries. This can help decision-makers set targets and take actions accordingly. Although a range of approaches exist, sharing principles that prioritize human needs fulfillment for all people are not properly developed. To address this gap, we develop sufficiency-based sharing principles. We do so by quantifying the life cycle impacts of satisfying decent living standards for the population of a high-income country in 2050 (Denmark) and comparing these impacts to planetary boundaries to identify a possible ‘sufficiency consumption space’. From this exercise, we infer two sharing principles. The first sharing principle assigns the allowed environmental impacts to all decent living standard consumption categories across 16 life cycle impact categories. The second sharing principle uses the degree of luxury of all goods and services in the economy, operationalized by expenditure elasticities, as a principle to share the sufficiency consumption space at a product-level. Together, these two sharing principles form a coherent suggestion for how to share a country's safe operating space, split between decent living consumption and remaining consumption. Our study thereby represents the first systematic and quantitative attempt at allocating a country's safe operating space according to human needs fulfillment and prioritizing a sufficiency consumption space according to the degree of luxury. Future research can address limitations of our study by, for example, using more granular life cycle inventory data and household expenditure data.

Empirical research on barriers to a circular plastics economy has predominantly relied on case study approaches. While research has provided insights into the conceptual and anecdotal aspects of these barriers, a gap remains in the application of formalized methodologies to systematically understand and address them. This paper seeks to bridge this gap by developing an equation system tailored to the plastics industry, bringing clarity to the complex interplay of factors that constitute barriers to a circular economy. The study identifies four primary barriers to the circular economy, as documented in the literature between 2017 and 2024: economic, institutional and regulatory, technological, and social. The results include 24 equations, synthesized into four master equations. A mathematical case study demonstrates how numerical weights, and the relative importance of variables can differ between countries, offering a practical guide for applying the framework across diverse contexts. The study concludes that reducing regulatory ambiguity, scaling recycling infrastructure, and fostering consumer trust in recycled materials are critical steps. However, each country will face unique challenges, requiring policymakers to adopt tailored approaches and variable weighting.

Renewable energy will dominate India's grid in the future. The intermittent nature of renewable energy requires energy storage. This research examines grid-scale deployment options for India, including pumped hydro, lithium-ion batteries, vanadium redox-flow batteries, molten salt storage, and compressed air energy storage. A cradle-to-grave life cycle assessment for midpoint categories was conducted in SimaPro. Pumped hydro storage exhibits the lowest impact in all the categories. Vanadium redox flow batteries exhibit the highest degradation scores in almost all categories except non-carcinogenic human toxicity, where the anode graphite causes the most impact in lithium-ion batteries. The impacts are found to be most sensitive towards electricity usage, except for molten salt storage (solar collectors) and usage of tetrafluoroethylene in vanadium redox flow batteries and salts (sodium and potassium nitrate) in molten salt storage for stratospheric ozone depletion, using anode graphite in lithium-ion batteries for terrestrial ecotoxicity. The techno-economic study shows that the lowest levelized cost of storage is ₹7.88/kWh (0.1 US$/kWh) for pumped hydro and the highest at ₹15.86/kWh (0.2 US$/kWh) for vanadium redox flow. Sensitivity analysis showed that pumped hydro storage is most sensitive to changes in power purchase prices. The cost of lithium-ion, molten salt, compressed air energy storage, and vanadium redox-flow battery is most susceptible to capital expenditure and roundtrip efficiency. Further, the Global Change Analysis Model (GCAM) projections revealed the vanadium redox flow battery to be the most expensive. Pumped hydro storage was the most affordable due to its higher energy efficiency and longer lifespan.

The electric vehicle industry's growth highlights traditional batteries' limitations in range and safety. This study, based on actual production data from China, employs Life Cycle Assessment (LCA) to quantify the environmental impacts of solid-state batteries (SSB) and lithium‑sulfur batteries (LSB) from “cradle to gate”, aiming to provide a scientific basis and optimization paths for sustainable automotive industry development. The study also examines how variations in the power grid's energy structure over time and space affect the environmental impacts of next-generation battery production. Results show that manufacturing 1 kWh of SSB and LSB can reduce carbon emissions by 15 %–31 % and cumulative energy demand (CED) by 21 %–31 %, respectively, but the drying room's environmental impact proportion rises compared to traditional batteries. Key materials like cathode and anode active materials significantly affect ecological indicators. Notably, nickel sulfate in SSB contributes over 85 % to photochemical oxidation and acidification indicators, while the sulfur cathode in LSB affects all indicators minimally (<3 %), demonstrating superior environmental performance. In Northern China, with low renewable energy generation, carbon emissions of LSB, Li2S-P2S5-based sulfide SSB, and Li6.4La3Zr1.4Ta0.6O12-based oxidic SSB increase by 5 %, 18 %, and 13 %, respectively. In Southwest China, with a higher renewable energy share, emissions decrease by 9 %, 11 %, and 8 %. As China's power grid energy structure upgrades, expected carbon emissions reductions are 8 %, 12 %, and 10 %, respectively. This indicates that sulfide solid-state batteries are most sensitive to power grid energy structure changes, followed by oxide solid-state batteries, with lithium‑sulfur batteries being the least sensitive. The study concludes that key battery materials' resource consumption and environmental issues remain major challenges for next-generation battery technologies. Developing eco-friendly battery materials, recycling technologies, and increasing local power grids' renewable energy share is vital for reducing next-generation battery production's environmental impact.

The growing need for agricultural production and the consequences of climate change necessitate new paradigms for sustainable resource management such as the Water-Energy-Food-Ecosystem (WEFE) nexus and the circular economy approach. The WEFE nexus promotes a holistic perspective to improve resource management and economic outcomes by emphasizing the interconnectivity of its components. The circular economy framework complements the WEFE Nexus by promoting the efficient use and reuse of resources across its interconnected components. This study proposes an integrated framework for preliminary assessments of water and agriculture sectoral potentials in water reuse and bioenergy production at a macro scale. This framework includes priority assessments using multidimensional criteria through the developed Circular Agriculture Priority Assessment (CAPA) index, which provide actionable insights targeted policies, strategic investments, and research to provide water, food, energy security and maintaining of ecosystem health in Türkiye. The results indicate that Türkiye's annual resources include 22.5 million tons of crop residue, 93.8 million tons of animal manure, and 2594 hm3 of urban wastewater, which could meet 10 % of agricultural water needs through reuse and produce 12,908,772 MWh of bioenergy, covering 4.16 % of residential electricity demand. However, only 14.6 % of this energy potential is currently exploited. The CAPA index highlights certain provinces for targeted policies, strategic investments, and research initiatives. By providing a multidimensional evaluation of circular agriculture strategies within the WEFE nexus framework, this research contributes to advancing sustainable resource security and improving decision-making in agricultural production systems.

The relevance of certain environmental impacts on agricultural processes, such as water use and degradation, biodiversity loss, and effects on ecosystem services, is widely recognized by the Sustainable Development Goals. However, agricultural Life Cycle Assessments (LCAs), among others, those on citrus fruits, often neglect or only partially address these impacts. This study seeks to fill this gap by evaluating these newly developed impact categories using orange cultivation in Uruguay as a case study. Updated and regionalized methods based on both midpoint and endpoint indicators are applied in a comprehensive cradle-to-farm gate analysis using mass and area functional units. The assessment specifically evaluates the effects of water consumption and degradation, land occupation on ecosystem services across five distinct potentials, as well as the impacts on biodiversity of both land use and those associated with resource use and pollutant emissions. Irrigation is the main contributor to water consumption-related impacts, with scores of 1545.2 m3 eq.·ha−1 and 88.5 m3 eq.·tonne−1 for blue water scarcity. As for water degradation, the main hotspots are fertilizers on-field emissions and production, along with that of copper oxides and the maritime transport of inputs. The pollution deprivation potential is quantified, obtaining scores of 1.1 · 10−2 m3·ha−1 and 5.7 · 10−4 m3·tonne−1. Land occupation for orange cultivation is the critical stage for ecosystem services loss — although it positively affects groundwater regeneration. The scores for biodiversity loss due to land occupation are 4.4 · 10−7 PDF·ha−1 and 2.6 · 10−8 PDF·tonne−1. Regarding non-land use-related impacts on biodiversity loss, input transportation stands out due to its significant contribution to terrestrial ecotoxicity. Based on the results, suggested management practices are put forth to mitigate the environmental impacts. Furthermore, areas for potential methodological enhancement are identified. This study provides the first application of recently developed environmental indicators for agricultural LCAs to citrus fruit cultivation, aiming to boost the development of more comprehensive studies that consider critical environmental aspects of agricultural systems.

This study aimed to assess the social performance of a low-tech digester implemented in a small-scale farm in Colombia. To this aim, a Social Life Cycle Assessment framework was developed to evaluate two scenarios: i) previous (baseline) scenario where manure was stored in a manure pit, liquefied petroleum gas was used for cooking and synthetic fertiliser was applied to crops; ii) current scenario where a low-tech digester treats manure and produces biogas and biofertiliser (digestate). The biogas is used for cooking replacing the liquefied petroleum gas while the digestate replaces the synthetic fertiliser. The stakeholder groups considered were: farmers/digester users (i.e. workers), local community, value chain actors, society and consumers. The impact categories were: cultural heritage, health and safety, working conditions, education, human rights, socio-economic repercussions, and consumer vs. user relationships. Results showed that low-tech digester implementation had a better social performance than piling up organic waste (with a final score of 36 and 10, respectively). This was mainly due to: i) education improvement and poverty alleviation for farmers; ii) improvement of community engagement, access to material resources (fuels, fertiliser, food) and education for the local community; iii) enhancement of social responsibility and supplier vs. user relationships for value chain actors; and iv) improvement of transparency and feedback mechanisms for consumers. Implementing low-tech digesters in the frame of a wider programme led by local entities and aiming at training and empowering farmers is a key issue for achieving the aforementioned social benefits and deep and long-term social change. More efforts should be made to reduce potential health and safety risks for all the stakeholders by i) training users to perform daily maintenance checks, and ii) setting up strategies to improve digestate quality for its safe reuse in agriculture.

In view of the fact that the rapidly growing number of electric vehicles around the world will result in more used batteries, how to efficiently recycle used batteries has become an important issue for sustainable development practices. Recognizing that the recycling of used batteries is affected by many factors, there is an urgent need to clarify the barriers to recycling used batteries. The lack of systematic reviews has led to an incomplete understanding of the barriers to battery recycling and a failure to effectively integrate the results and perspectives of various studies. In this paper, a systematic literature review has been conducted according to the PRISMA systematic review checklist to explore the current state of scientific research on the factors influencing the recycling of used batteries in order to summarize the potential barriers to the recycling of used batteries. By analyzing 92 articles from Web of Science and Google Scholar, this study identifies the key factors affecting the recycling of used batteries, including six dimensions: technology, economy, society, environment, policies and regulations, and supply chain, and systematically analyses the barriers within each dimension. Furthermore, this paper highlights several potential future research directions to further overcome these barriers, i.e. the need for comprehensive influencing factor studies, recycling network optimization, consumer behavior, policy effectiveness assessment, recycling market mechanisms, life cycle assessment, case studies, battery life data and cross-industry collaboration. These research directions provide practical guidance for researchers to further explore the recycling of used batteries and provide insights for practice and research towards a circular economy.
