Improving the recycling rate and efficiency requires a fast, reliable and uncostly analytical method. Although the X-ray fluorescence (XRF) shows high potential, it is often unreliable. In this study, we propose a novel XRF methodology for the elemental analysis of PCBs, using the certified reference material (CRM) to decrease uncertainty and enhance accuracy. The results show significant improvement in robustness and accuracy of portable XRF(pXRF) analyses for elements Cu, Pb, Ni, As and Au, with a relative average inaccuracy of approximately 5% compared to referenced values. The methodology validation carried out by comparing pXRF and inductively coupled plasma mass spectroscopy analyses of personal computer motherboard samples shows no statistically significant difference for elements Cu, Cr and Ag. The study shows that the calibration of pXRF by CRMs enables the necessary analysis of PCBs in an efficient and reliable manner and could be also be applied to different types of PCBs and other electronic components, batteries or contaminated soil samples.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"397-407"},"PeriodicalIF":3.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141076926","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}

Studies have reported that transporting garbage has challenges related to public exposure and aesthetics. This study presents a generalised bi-objective formulation for the optimal routing of garbage trucks from transfer stations to recycling sites/landfills considering the trade-off between public exposure and aesthetic loss and constraining the operating cost. The formulation uses the novel link capacity function to account for the delay at traffic signals and the mix of trucks and cars on link performance. The proposed formulation is solved using the weighted sum and ε-constraint methods and applied to a realistic case study of the City of Chicago, USA. The Pareto Front obtained for the bi-objective formulation offers diverse trade-off solutions catering to distinct performance metrics. The results highlight the disparity across the solutions; the solution (P0.95 on Pareto Front) for minimum operating cost (or travel time or distance travelled) is very different from the solution (P0.4 on Pareto Front) for aesthetic cost and public exposure. The parametric study indicated that a modest operating budget may suffice for achieving aesthetic benefits, but minimising public exposure requires a higher operating budget. Finally, the proposed framework is adaptable to address various challenges pertaining to waste transportation, thereby serving as a valuable tool for evaluating policies and practices geared towards sustainability objectives.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"369-377"},"PeriodicalIF":3.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141088446","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}

This study applied the Behaviour Change Wheel and the capability, opportunity, motivation-behaviour model to develop and evaluate the effect of a behaviour change intervention on the disposal of compostable packaging at workplaces. 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.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X251322145"},"PeriodicalIF":3.7,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","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":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there is a wealth of research on the primary causes of food waste, little attention has been given to the link between surplus production and waste generation. Current approaches to reducing food waste predominantly focus on redistributing surplus rather than preventing its formation. This study conducted a systematic literature review (SLR) to delve into the concept of food surplus and understand its relationship to food waste. It also seeks to pinpoint the key challenges and limitations of redistributing food surplus. This SLR revealed that the definition of food surplus is ambiguous and lacks clear parameters for determining what qualifies food as surplus. As a result, food edible for consumption is often categorized as surplus and may or may not be recovered. The classification of food as surplus or waste is intricate and is influenced more by economic factors than physical characteristics. While food redistribution via food banks is crucial for addressing food insecurity, it encounters technical and operational obstacles that limit high levels of food recovery. Therefore, preventive strategies should be implemented to curb overproduction, which appears to be the root cause of surplus formation and waste. However, reducing overproduction requires structural changes in the current food system logic.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X251320878"},"PeriodicalIF":3.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143493797","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}

Until now, very few biowaste source-segregation initiatives have been carried out on this part of the world. This study aimed at assessing the biowaste sorting efficiency and the attitude of households towards a pilot biowaste source-segregation system linked to a decentralized composting plant in Tiassalé. For this purpose, the impurity rate of source-segregated biowaste was monitored through the first year of implementation. Then, a cross-sectional survey was conducted to evaluate households' attitude. The results have shown that the average impurities rate in source-segregated biowaste was very low (1%). This finding was confirmed by the results of laboratory analysis which revealed a very low heavy metals (0.2, 12.4, 7.1 and 15.5 mg kg-1 DS for Cd, Cr, Ni and Pb, respectively) contamination in the compost produced. Regarding the acceptability of the source-segregation system, the results showed that the majority (75%) of the participants accepted the source-segregation system of biowaste and almost half (47%) of them were ready to pay for such a collection service. In conclusion, this study revealed that providing households with the needed municipal solid waste management infrastructures and rising awareness about biowaste source segregation are keys for the establishment of such a collection system in Tiassalé and similar urban areas. The findings also proved the effectiveness of biowaste source-segregation system in the production of high-quality compost.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X251313919"},"PeriodicalIF":3.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415522","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}

This study reports on a bibliometric analysis that has identified the extent to which the topic has been explored in the international literature, by focusing on geographical scope, the emphasis on (micro)plastic litter and on policy measures. Additionally, as a complement to the assessment of the recent literature on marine plastic litter, this study reviews some case studies, identifying some trends on how to cope with this problem. The findings underscore the imperative for heightened research efforts in the context of marine littering. The literature reveals that unsustainable practices, the absence of robust policies and inadequate enforcement substantially contribute to the prevalence of marine plastic litter. Consequently, urgent action is essential, demanding the implementation of effective policies and frameworks. Encouraging nations to transition towards marine sustainability, particularly in terms of prevention and environmental awareness, is of paramount importance. To pave the way for a cleaner ocean for future generations, this study not only highlights the root causes but also offers suggested solutions. These solutions serve as valuable insights for researchers, innovators and policymakers worldwide, charting a course towards a more sustainable and litter-free marine environment.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X251313927"},"PeriodicalIF":3.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415546","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}

Our findings show that although the programme implementation represented a significant advance in Ecuador's waste management system there are important challenges that should be considered in future adaptations of the programme. Among the measures that can be adopted to improve the ELT management system are the consolidation and stimulation of the market for products made from ELT waste; promotion of other productive sectors linked to the creation of new products and sectors that generate complementary products; enhancement of the generation, socialization and access to knowledge of the waste by-products for micro-, small- and medium-sized enterprises; increase the tire consumer fee, known as 'Ecovalor' and improvement of the quality and availability of information and indicators regarding ELT management.
