Recycling spent Cd-enriched adsorbents into efficient catalysts for advanced applications could address the environmental issues and attain the carbon neutral goal. Herein, a facile strategy is developed for the first time to reutilize the alkali lignin (AL)-derived biochar (ALB) absorbed with Cd into cadmium sulphide (CdS)/C composite for the efficient methylene blue (MB) removal. The ALB is initially treated with Cd-containing solution, then the recycling ALB samples with adsorbed Cd are converted to the final CdS/C composite using NaS2 as the sulphurizing reagent for vulcanization reaction. The optimal ALB400 demonstrates a high adsorption capacity of 576.0 mg g-1 for Cd removal. Then the converted CdS/C composite shows an efficient MB removal efficiency of 94%. The photodegradation mechanism is mainly attributed to carbon components in the CdS/C composite as electron acceptor promoting the separation of photoelectrons/holes and slowing down the abrasion of CdS particles. The enhanced charge transfer and contact between the carrier and the active site thus improves the removal performance and reusability. This work not only develops a method for removing Cd from wastewater effectively and achieving the waste resource utilization but also further offers a significant guidance to use other kinds of spent heavy metal removal adsorbents for the construction of low-cost and high value-added functional materials.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"75-85"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139933123","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}

Waste recycling is known as an efficient approach to improve sustainability and save energy. In this view, a sustainable supply chain is established in the current study to investigate the effects of waste recycling on sustainable development. The considered supply chain consists of the government, two manufacturers, a supplier, a waste depot, and a recycler. Under this structure, two substitutable products are made of the virgin and recyclable waste materials. The supplier provides the virgin materials for the first product. The waste depot collects the non-recycled waste, whereas the recycler recycles it and supplies the recycled waste for the second product. Also, the government supports the second product to provide an incentive for its members to collect and recycle more waste. Then, the game theory is applied to make decisions under the considered structure. Finally, the results are revealed and some managerial insights are provided. It is derived that the governmental supportive policies play a significant role in resources conservation and energy storage. Moreover, increasing the quality of the product made of the recyclable waste improves the government's utility.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"62-74"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141154855","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}

However, the BMP test is not standardized making comparison of BMP results across sites problematic. For example, the BMP test duration has historically ranged from 20 days to several months with most current BMP tests lasting 60 days. However, the gas generation data can potentially be modelled for any of those durations to produce a prediction of the ultimate BMP value (BMPULT). Currently, the predicted BMPULT values of 23 long-duration (115-150 days) BMP tests were used to determine the required quantity of data (i.e. number of days) needed to produce an accurate BMPULT prediction. Results showed that no single test duration produced both accurate and efficient results, so a novel performance-based endpoint was proposed. The relative change in predicted BMPULT values with respect to time (dBMPULT/dt) was chosen as a potential performance-based completion metric. Results indicate that once the absolute normalized dBMPULT/dt value is within <2.5, <1.5 and <0.6% day-1 that the predicted BMPULT is within 20, 10 and 5% of the true BMPULT, respectively. Overall, the use of performance-based metrics for determining BMP test completion will allow for the collection of partial data sets, reduced experimental times and verification of results.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"112-120"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11689784/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139651788","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}

Environmental impacts and high management costs affect the sustainable development of cities, an issue that is exacerbated by the lack of social involvement. The research conducted in Iran aims to assess the benefits of organic waste home composting in Shiraz to improve solid waste management (SWM) sustainability. The introduction of a pilot project to assess home composting systems was described, together with an economic, social and environmental analysis. The current SWM system (S0) has been compared with the new strategy proposed (S1), where home composting is considered to be introduced to collect about 10% of the municipal solid waste generated in a 10-year horizon. An economic balance related to the capital costs and operational costs of both systems was introduced, in parallel with a life cycle assessment (LCA) of the SWM system, and a questionnaire survey of the local population. Results showed that S1 leads to around 5% economic savings for the municipality due to the avoidance of organic waste transportation and disposal. Environmental benefits include a lowering of CO2-Eq emissions of about 19,076 tonnes year-1. In addition, about 28% of the interviewed (n = 319) agreed to employ the home composting system at home (CI 5.5%, 95% of confidence level) supporting the theory that about 10% of the organic waste can be segregated and home-composted. The research underlines that home composting can contribute to improve the sustainability of SWM systems in developing countries.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"97-111"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11690229/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139708058","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}

Furthermore, a better understanding of the comminution behaviour of shredders with fixed settings (gap width, shaft speed, cutting tool geometry) is in the focus of the present investigation and assessed, using the statistical analyses for particle size distribution in certain screen sections. Conclusions have been drawn on the comminution behaviour in general and the material-material interactions of different fractions in the grinding chamber of the shredder by showing significant differences in the pure fraction's comminution behaviour against the mixture's comminution behaviour. In addition, the effect of the wear condition of the cutting tools on the particle size distribution has been investigated using statistical tests. As a result, interactions of the materials in the shredder grinding chamber can be demonstrated. The null hypothesis of the statistical test can be rejected due to the p-values, which are around 0.01 and therefore less than the predetermined alpha, which is 0.05, meaning that the shredding behaviour of pure fractions and those in a mixture is different. Additional investigations of waste wood only have shown that the wear condition of the cutting tools does not exhibit any effect on the particle size distribution of waste wood, as seen in the p-value (0.29), which is higher than the used alpha value. This could mean that the cutting tools need to be changed less frequently, which could have a positive effect on plant operation.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X241306602"},"PeriodicalIF":3.7,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142898583","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}

In 2022, the Government of India enforced the Plastic Waste Management Rules to manage plastic waste. This article aims to find the potential impact of these rules on plastic waste generation from now until 2050. The simulation is carried out in two steps. In step one, a material flow analysis is conducted that maps plastic flow from production to its end-of-life. Through this it is estimated that at an optimistic level, off the 20 million metric tonnes (Mt) of plastic consumed, around 10 Mt is added to stock, 4.5 Mt is recycled, 2.5 Mt is reutilized and the balance 3 Mt is mismanaged. In step two, through system dynamics model, the impact of policy instruments is estimated on each stage of the flow of plastic assuming a phased implementation. Through this model, it is found that annually mismanaged plastic waste increases 11 to 28 Mt in 2050 in a business-as-usual scenario; however, implementing all the policies in a phased manner would stabilize waste generation from 2040 onwards.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X241304342"},"PeriodicalIF":3.7,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142898582","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}

A structured analysis of literature about the war and post-war impact on the environment paired with 'grey literature' and the collection of currently available information from regional and national government agencies and official organizations on the specific situation in Ukraine, with a particular focus on waste management issues, was conducted. The main groups of environmental components affected by military actions are analysed, systematized, and classified. It is shown that the negative impact of military actions has irreversible consequences for the environment not only in Ukraine but is also already gaining global proportions. In addition, much of the infrastructure in the waste management sector has been destroyed, meaning that large volumes of unsorted and untreated waste are now ending up in landfills, most of which are uncontrolled since other more effective and sustainable environmental and waste management options are currently missing. Therefore, it is necessary to develop remediation concepts and implement comprehensive measures to clean up the territories and restore environmental components and the waste management sector after war. This includes - among other issues - assessing or measuring the generation and composition of post-war demolition waste and municipal solid waste during and after the war as a basis for further planning and decision-making.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X241305909"},"PeriodicalIF":3.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142830018","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}
