Focus groups, observations, analysis of existing materials and a review of the literature identified barriers in relation to capability, opportunity and motivation to compost packaging. The intervention addressed the identified barriers through clear and distinctive labels on packaging, matching bin signage, a motivational video and an onboarding presentation for workplaces. The intervention was implemented in three workplaces and evaluated using a pre-post design. The intervention led to sustained increases in compostable packaging in compostable bins and reduced contamination. A post-intervention survey and roundtable event suggested that the intervention was acceptable to workplace leads and employees. There was no evidence that the intervention changed perceived capability, opportunity and/or motivation. The main recommendations for packaging producers and workplaces include using consistent distinctive bin signage that corresponds with standardized packaging labels.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1625-1635"},"PeriodicalIF":4.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12476459/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143504344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the role of digitalization in waste management (WM) is underexplored, and the literature remains fragmented. This study explores the synergy between CE principles in tourism and decarbonization in the waste sector through digitalization, using case studies from Taipei (Republic of China) and Sukunan (Indonesia). By examining the integration of digital tools in WM systems, the study highlights how these cities leverage technology to promote net-zero emissions and sustainable practices, particularly in the context of tourism. The research employs a mixed-methods approach, combining qualitative data from focus group discussions, semi-structured interviews and secondary data analysis. The findings reveal that digitalization has significantly improved WM efficiency, resource recovery (RR) and carbon footprint reduction in both study areas. Notably, the study demonstrates that tourism plays a role in driving these digitalization efforts, particularly through the adoption of CE practices in WM. The results suggest that digital solutions, when tailored to local contexts, can accelerate decarbonization and enhance sustainability. In Sukunan, technological adoption generated 780 new jobs and raised average household incomes by USD 45 monthly. These initiatives reduced landfill waste by 30% and cut CO₂-equivalent emissions by about 0.3 million metric tonnes annually. Taiwan's 'Pay-As-You-Throw' (PAYT) system is a benchmark, showcasing effective WM and resource recovery practices. Digitalization is projected to trim WM costs by 35%, reduce annual expenses by 3.6%, generate USD 493 billion in revenue over decades and subdue global CO₂ emissions by 15% by 2030. Overall, this work emphasizes the potential for replicating such strategies in other cities, with consideration for local conditions, to achieve sustainability and decarbonization goals in the tourism and WM sectors.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1605-1624"},"PeriodicalIF":4.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Effective strategies are crucial to mitigate impacts, maximising biowaste's valorisation. This article presents a systematic literature review on using life cycle assessment (LCA) to evaluate municipal biowaste treatment facilities. The primary objective was to analyse how LCA is applied to assess the environmental efficiency of mechanical and biological treatment involving composting and anaerobic digestion (AD)-based systems. The article addressed the methodological heterogeneity across previous LCA studies, identifying critical gaps and challenges regarding standardisation and result comparability. It underscores the importance of accurately considering environmental indicators and emission factors, as these significantly affect overall LCA outcomes. Results show that most publications focus on Europe and Asia, highlighting a research gap in regions like Africa. The organic fraction municipal solid waste is the predominant feedstock, and 1 tonne of biowaste was the frequently used functional unit, reflecting the upstream impacts of waste. The most recurrent system boundary was the cradle-to-grave, offering a comprehensive analysis as it covers all stages of biowaste treatment from collection to disposal. The studies highlight the environmental benefits of AD-based systems through energy production compensations, particularly in reducing global warming potential, compared with other treatment operations such as landfills. While replacing mineral fertilisers with digestate and compost is very well discussed, it raises concerns about heavy metal content and nutrient availability. Therefore, selective collection of organic waste is crucial to improve compost quality and AD efficiency, though it increases transportation costs.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1509-1524"},"PeriodicalIF":4.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12476467/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143721596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to determine the elements that significantly impact the intention of mobile phone repairers to carry out separation of e-waste. The integrated model incorporates Self-Determination Theory (SDT) factors (viz., amotivation, external regulation, identified regulation, intrinsic motivation, introjected regulation and integrated regulation) and Institutional Theory (IT) factors (viz., coercive pressure, mimetic pressure and normative pressure).

Moreover, this research utilized a hybrid data analysis method, using partial least squares structural equation modelling and artificial neural network to assess the model. The findings of this study indicate that all the SDT and IT factors are supported, except coercive pressure. This research adds to the existing body of knowledge on e-waste separation by shedding light on the problem from the viewpoint of mobile phone repairers, offering useful information to governments and waste recycling companies to understand the intentions of repairers with respect to e-waste separation and formulate such strategies that can enhance the involvement of repairers in e-waste separation activities.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1559-1576"},"PeriodicalIF":4.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144037069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The intervention targeted barriers to the appropriate disposal of compostable packaging as identified via focus groups, previous research and the capability, opportunity, motivation-behaviour model. Intervention components included front- and back-of-pack labels, tips on positioning of household bins, visual reminders to check packaging labels and which bin to use, and a bag of compost with an infographic highlighting what happens during the composting process. The intervention was delivered over 6 weeks to 120 households who were provided with compostable and non-compostable items. The results from online surveys completed at three time points (pre-intervention, post-intervention and follow-up) and weekly waste audits that assessed the weight of compostable packaging in the food and garden waste bin showed significant increases in perceived capability, opportunity and motivation to correctly dispose of compostable packaging via the food and garden waste bin over the course of the intervention and increased amounts of compostable packaging disposed of.

This study employs the concept of the theory of perceived risk to examine the influence of social and financial risk, online retail channels and return policy on consumer-perceived risk. Additionally, it proposes that an online retail channel with a lenient return policy may enhance the intention of consumers to purchase refurbished products. The hypotheses were examined using partial least square structural equation modelling. The findings suggest that social risk, return policy and financial risk significantly enhance the perceived risk of purchasing refurbished products, but the online retail channel does not substantially impact perceived risk, which may be if both online and offline channels provide the same level of support and policy. The results also indicate that perceived risk mediates consumers' online purchase intention for refurbished products. This study is distinctive because it analyses the effects of social and financial risk, return policy and retail channel on consumers' perceived risk when purchasing refurbished products online. This study examines the concepts of online purchasing of refurbished products, which have received limited attention in existing literature.

In Australia, many consumers tend to stockpile old small EEE, which limits collection rates and reduces the potential for resource recovery. This study aimed to assess consumer behaviour related to the collection of small EEE in Australia through a multivocal literature review and an online survey of 403 respondents. The analysis revealed that consumers are disposing of small WEEE along with general household waste, and most are uncertain of the correct disposal method. Almost half of the respondents are willing to pay to manage small WEEE and prefer to drop them at a designated location. Hence, to increase the collection rates, this study recommends setting realistic collection targets based on products on the market rather than waste generation estimates based on average lifespan. In addition, correct disposal can be encouraged by integrating small WEEE in kerbside collection and providing incentives. In order to strengthen this, awareness campaigns should target all age and income groups to increase collection rates and product circularity.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1548-1558"},"PeriodicalIF":4.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12476481/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144044368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article introduces a novel simplified and comprehensive framework for assessing waste prevention and minimisation measures tailored to developing countries. The primary contribution of this study lies in proposing relevant indicators aligned with the SDGs, ESG standards, and CE principles, while addressing data scarcity through proxy indicators to enable effective assessment in resource-limited settings. Six key indicators were proposed: Zero Waste Index, Food Loss Index, Extended producer responsibility, Education and awareness programmes for waste minimisation, Waste prevention and Plastic Bag Reduction Ratio. Eleven countries were selected as case studies to demonstrate the framework's applicability. The findings reveal that while these countries are progressing in enacting legislation and recognising the importance of waste prevention, compliance in practice is lacking, as indicated by poor quantitative results in actual waste reduction and diversion. The framework evaluates the environmental, social and economic implications of waste prevention measures, showing wide variations among countries. Each country faces unique challenges, but strengthening policy frameworks, investing in infrastructure, promoting public awareness and fostering collaboration are key steps towards advancing sustainable waste management practices. The study highlights the necessity for tailored policies addressing specific weaknesses while ensuring economic viability.
