Fruiting vegetable production is being incentivized in this industry to diversify the product offerings. However, this production model has yet to receive substantive evaluations on environmental performance. This study conducted experiments and employed life cycle assessment (LCA) to evaluate the environmental performance of tomato production in VF, comparing it with tomato production in high-tech greenhouses and lettuce production in VF. The environmental impact of the global warming potential of tomato production in VF was four times higher than that of tomato production in high-tech greenhouse, standing at 22.87 kg-CO₂eq/kg, primarily due to the energy consumption of lighting. In response to this systemic hotspot, this study evaluated the impact of light emitting diode (LED) technology upgrades and energy choices on the environmental performance of this production model. It was found that both LED efficiency and electricity cleanliness are sensitive factors. Considering Japan's carbon neutrality goals, a shift to renewable energy could reduce the environmental impacts of global warming potential and fossil fuel consumption of tomato production in VF by up to 50 %. Combining LED upgrades with renewable energy could reduce the environmental impacts by 60 %, making tomato production in VF competitive with tomato production in high-tech greenhouse and lettuce production in VF in terms of sustainability.

This study aims to comprehensively evaluate the environmental, economic, and technological trade-offs of nine textile waste recovery technologies for waste cotton, polyester, polyester-cotton blends, and mixed textile waste in China. By integrating life cycle assessment, life cycle costing, and the VlseKriterijumska Optimizacija I Kompromisno Resenje method, this study provides a methodology framework to balance conflicting objectives. The results showed that chemical recovery led to higher costs but made greater revenue, whereas mechanical and physical recovery demonstrated higher technological maturity and material retention, with lower energy consumption and waste generation. In addition, mechanical and physical recovery achieved the most significant reductions in global warming potential, energy consumption, human health damage, and resource consumption. Based on environmental, economic, and technological trade-offs, it is hold that mechanical recovery is the most balanced option for waste cotton, physical recovery is the more stable solution for waste polyester, refuse derived fuel (RDF) production is the optimal choice for mixed textile waste, and chemical recovery is more suitable for polyester-cotton. These findings suggest that optimizing textile waste recovery in China could annually save of approximately 25 million tons of CO₂ emissions, 1 billion cubic meters of fresh water, and 23 thousand tons of fossil fuel. The important implications are that a refined recycling network and material flow should be set up for all kinds of textile wastes, and RDF standards should be established in China and regulate the usage ratio in energy facilities and cement plants, so as to enhance mixed textile waste recovery.

This study therefore aims to explore the barriers and drivers for bio-CO₂ utilization and their implications for shaping the bio-CO₂ market, using Sweden as an example due to its diverse bio-CO₂ sources and existing initiatives. Twenty-four actors were interviewed, representing different types of market actors, which enabled differences between actors to be identified. For example, producers emphasized economic and market-related barriers, while users addressed uncertainties related to the supply chain and quality requirements. Among the key barriers identified are an uncertain policy landscape, as well as economic and market-related barriers that hinder bio-CO₂ utilization. Improving environmental performance is identified as a key driver for bio-CO₂ utilization but requires overcoming barriers such as high costs and payback requirements to become enacted. Other identified key drivers are the potential for new market opportunities for CO₂, such as e-fuel production, and an increased interest in bio-CO₂ over its fossil-based counterpart. There is a need for a diverse set of actions to support the development of the bio-CO₂ market, such as long-term, stable policies and regulations that support investment and market creation, along with better coordination among governmental organizations. This study thus contributes a holistic perspective on the prerequisites for bio-CO₂ utilization by exploring barriers and drivers for bio-CO₂ from different market actor perspectives and identifying policy implications, using Sweden as a case study.

The methodological design of this study follows a systematic approach to theory building, incorporating an analysis of current CE policy formulation as formalised in roadmaps and CE indicators. Our work results in a ‘nexus of circulation’ conceptualization, which identifies 8 distinct linkages through which circular economy initiatives interact and impact each other across systems of provision. We show how such linkages can act as conduits for acceleration or for slowing down the circular transition in an economy. The results also provide evidence showing that the identified linkages are not at the heart of current policy making for CE, as they are reflected at best partially in CE indicators and CE roadmaps. We conclude that this likely results in limiting the scope of circular interventions, resulting in unintended negative consequences elsewhere in the economy, or in the economy as a whole. The proposed ‘nexus of circulation’ conceptualisation has been purposefully designed from a policy design perspective, so that it helps societal stakeholders to recognize leverage points across systems of provision in a way that enables active policy making towards accelerating the circular transition and helping to eliminate obstacles that block this transition.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"56 ","pages":"Pages 408-419"},"PeriodicalIF":10.9,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DES-HD achieved the highest yield (0.78 %), then followed by UA-HD, CA-HD and HD. The antioxidant activity of DES-HD essential oil was 1.5 times that of HD, and it was attributed to its elevated total monoterpene/oxygenated monoterpene content (91.37 % for DES-HD vs. 81.40 % for HD), which also enhanced its antimicrobial performance. However, LCA revealed DES-HD as the least sustainable option due to energy-intensive DES synthesis and significant toxicity impacts, challenging its designation as a “green solvent.” To offset its ecological footprint, DES-HD would require a yield exceeding 1.78× that of UA-HD. In contrast, UA-HD emerged as the most sustainable and economically viable method, with the lowest standardized environmental impact and industrial energy consumption (2.07 kWh/kg), minimal selling price ($17.51/kg), and shortest payback period (4.46 years). Sensitivity analysis identified electricity consumption and solvent production were the dominant factors causing environmental burden, which can be mitigated by improving energy efficiency and solvent recovery, reducing extraction time, and attempting low-carbon transition of electricity generation mix. These findings highlight UA-HD as the optimal technique for rosemary essential oil production, while cautioning against the uncritical adoption of “green” solvents without holistic environmental and economic validation.

In the global south, particularly in Sub-Saharan Africa, small-scale farming serves as a crucial lifeline for the food and income needs of local populations. Yet, it remains underfunded and under-researched in the context of sustainable development. Even if the traditional Life Cycle Sustainability Assessment offers a holistic approach to evaluating the impacts of staple food processing across environmental, economic, and social dimensions, its inability to track dynamic materiality limits its application in evaluating future impacts. Therefore, this study aimed to provide a comprehensive Life Cycle Sustainability Assessment framework for staple food processing, using cassava to produce gari, a staple food for more than 300 million West Africans, as a case study. This framework integrates Material and Energy Flow Analysis techniques to trace resource use and emissions. The research incorporated Environmental, Social and Governance pillars; double materiality, evaluating both the direct and indirect impacts of processing activities, alongside dynamic materiality to capture evolving environmental, financial, and social factors through scenarios. Python computational modeling was used to perform these complex analyses, ensuring accuracy and adaptability. The findings highlight significant energy inefficiencies (6.67 kWh kg^-1) coupled with a high Global Warming Potential (GWP) of 9.02 kgCO₂eq kg^-1 and production costs of $0.56 kg^-1. The most significant opportunities for improvement were identified in optimizing energy consumption and transforming waste into biogas. The dynamic model revealed that integrating renewable energy sources could substantially reduce environmental impacts and increase the Net Profit Margin from 34.43 to 52.52 %, as proposed in the energy transition from woodfuel and gasoline to a Hybrid Solar and Biogas energy system.
