Utilizing a Life Cycle Assessment (LCA) methodology, the environmental and economic outcomes of conventional versus circular agricultural practices were quantified, focusing on key Area of Protection (AoP) including disability-adjusted life years (DALY), ecosystem damage (species.yr), and resource depletion (USD<sub>2013</sub>). The results demonstrate that conventional sugarcane and rice cultivation lead to substantial health impacts (up to 2910 DALY), significant ecosystem damage (up to 4.45 species.yr), and resource depletion costs of up to 14.9 million USD<sub>2013</sub>. In contrast, cassava cultivation, with its existing circular practices, shows comparatively lower impacts, including 415 DALY, 1.47 species.yr of ecosystem damage, and 10.4 million USD<sub>2013</sub> of resource depletion. Circular agricultural scenarios, using crop residues to produce organic fertilizers and animal feed, proved highly effective in reducing these burdens. Circular organic fertilizers reduced total costs by 57 %, while converting residues into animal feed resulted in a net economic benefit of 1.98 billion Thai Baht (THB), representing a 137 % reduction in costs compared to the baseline. The findings highlight the importance of transitioning to circular models, emphasizing the need for policy interventions, improved technology access, and enhanced farmer training to promote circular agricultural practices in Thailand.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"58 ","pages":"Pages 203-220"},"PeriodicalIF":10.9,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144570427","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}

However, critical questions remain regarding the types of information most crucial to facilitate Reuse, Refurbish, Repair, Remanufacturing and Recycling activities. This Information heavily depends on the intended treatment scheme like disassembly type. For instance, manual disassembly offers flexibility but is constrained by limited scalability and safety concerns, whereas robotic disassembly, although cost-efficient for repetitive tasks, is hindered by high capital costs and lacks adaptability. Flexible human-robot cooperative systems present a potential solution by balancing scalability, adaptability, and capital cost. Hence, ease of disassembly information and metrics tailored for such systems would not only benefit product designers in crafting circular designs, but also assist policymakers in assessing product circularity and aid remanufacturers in disassembly task scheduling and allocation.

Finally, recommendations are formulated on essential ease of disassembly information required for DPPs and the applicability and effectiveness of the proposed metric is demonstrated by the application of Re-DiM metric for three distinct product groups: vacuum cleaners, e-bike batteries, and electric vehicle motors.

This study introduces a new framework for integrating societal change into LCA using Agent-Based Modeling (ABM). Our approach leverages LCA metamodels, integrated with the ABM via defined linking parameters, to enable real-time feedback between agent decisions and environmental outcomes, while minimizing computational demands. We illustrate the applications of this framework in a photovoltaic case study, examining how end-of-life choices affect abiotic depletion and climate change. The ABM-LCA integration employs metamodels with high predictive performance, achieving R<sup>2</sup> values of 0.95 for abiotic depletion and 0.82 for climate change. Linking parameters are based on the number of PV modules entering different end-of-life pathways. Societal change, as modeled in the ABM, is driven by the assumption that increased awareness of environmental impacts promotes circular behaviors. The photovoltaic case study provides an illustrative exploration of how consumer choices may affect environmental impacts, such as abiotic depletion and climate change, and how these impacts, in turn, may shape future consumer behavior. This work highlights the value of using a metamodel-driven, integrated ABM-LCA modeling framework for decision-making in complex systems, uncovering unexpected system behaviors and offering insights into sustainable transitions.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"58 ","pages":"Pages 14-29"},"PeriodicalIF":10.9,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144313515","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}
