Inappropriate treatment and disposal of HCW may pose health risks to humans indirectly through the release of pathogens and toxic pollutants into the environment. The biggest problem in HCW management is its handling, which causes anxiety over sorting and categorizing the waste. Hence, the current study identifies and addresses the challenges towards sustainable environmental development by managing infectious HCW in developing countries. Fuzzy Delphi method is used in the present study to carefully examine the barrier drawn from the literature and experts' opinions. The number of barriers taken into consideration for study are 30, which are then grouped into four main categories, that is, social, environmental, technological and economic barriers. Additionally, a hybrid strategy based on the fuzzy decision-making trial and evaluation laboratory is developed in this work to examine the significance and interrelationships of the identified barrier. The research outcome is a hierarchy and classification model based on the relative importance of the barriers. The results of this study indicate that: 'Lack of segregation', 'Inconsistency in waste collection', 'Unregulated disposal site' and 'Inadequate programme for training and awareness' require quick action. The conclusions obtained through the study would facilitate the preparation of check sheets for documenting HCW management procedures by the healthcare administration and Pollution Control Boards. Understanding the priority cause-group barrier would improve the long-term protection of the hospital environment from the spread of infection caused by the HCW.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1079-1092"},"PeriodicalIF":3.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41152750","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 project team created various landfill operational scenarios for different regions of the planet with respect to waste composition, organic waste reduction and landfill gas recovery timing. These scenarios were modelled by applying a basic gas generation model according to the United Nations Intergovernmental Panel on Climate Change (IPCC) recommendations. In general, the IPCC's recommended modelling parameters and default values were used. Based on the modelling undertaken, two options stand out as being the most effective methane mitigation measures in a wide range of conditions throughout the world: (a) early gas recovery and (b) reduction of the amount of biodegradable organic waste accepted in a landfill. It is noted that reduction of organic input to any given landfill can take many years to realize. Moreover, suitable alternative processing or disposal options for the organic waste can be unaffordable for a significant percentage of the planet's population. Although effective, organic waste reduction cannot therefore be the only landfill methane mitigation measure. Early landfill gas recovery can be very effective by applying basic technologies that can be deployed relatively quickly, and at modest cost. Policymakers and regulators from around the globe can significantly reduce adverse environmental impacts from landfill gas emissions by stimulating both the early capture and flaring and/or energy recovery of landfill gas and programmes to reduce the inflow of organic waste into landfills.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1052-1064"},"PeriodicalIF":3.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11531075/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41214343","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}

Some of the environmental impacts of plastic waste include littering, the formation of plastic debris in oceans and the contamination of freshwater and terrestrial habitats. Policymakers face great challenges in mitigating plastic waste. Indonesia is considered the second largest contributor of plastic waste in the world. However, existing policies have not addressed this issue. Policies, such as bans on single-use plastic bags and fees on plastic bags, have recently been implemented in some pilot cities, but the results remain unclear. Thus, this study proposes feasible policies to mitigate plastic waste in Indonesia using system dynamics. Specifically, this study seeks to develop a dynamic model of plastic waste mitigation and to propose a policy scenario for plastic waste mitigation. The proposed policies consist of a plastic bag ban, a plastic bag fee, a recycling centre and extended producer responsibility (EPR). The analysis demonstrates that an effective mixed policy instrument for reducing plastic waste depends on the plastic waste type. Regarding plastic bottles, the effective mixed policy is a combination of a recycling centre and EPR. For plastic bags, the effective mixed policies include the following combinations: a plastic bag fee and plastic bag ban, a plastic bag fee and recycling centre and a plastic bag ban and recycling centre.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1008-1018"},"PeriodicalIF":3.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11529116/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139933080","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}

Ghana, over the years, has had support from international organisations to manage its e-waste crisis. Until 2016, there was no e-waste specific policy to guide the management of the sector. In 2016, Ghana passed a regulatory policy - Act 917 - to specifically deal with e-waste, supported by other frameworks such as a regulatory instrument (L.I. 2250), a technical guideline for environmentally sound e-waste management and an e-waste-specific policy, which is currently being developed. However, there is dearth of research on how effectively a regulatory policy such as Act 917 can help address an informally dominated sector whose crude recycling approaches have had great environmental and health impacts. Adapting the analytical framework and intervention theory, key stakeholders within the e-waste sector were interviewed on: the effectiveness of the Act, the challenges confronting them and their involvement in the design and implementation processes. The findings showed that stakeholders were represented at various stages of the process. Informal recyclers were provided with training programmes, health centres and an incentive scheme to minimise burning of electrical and electronic equipment. There however exist many challenges to the sound management of the sector, particularly, the lack of end-to-end recycling facilities, registering and formalising the sector and sequencing of the e-waste policy and regulatory framework. The research concludes by recommending areas for future studies.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1031-1041"},"PeriodicalIF":3.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71414128","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}

To reduce TPF litter quantities, Directive (EU) 2019/904 requires TPF producers to proportionally contribute to the costs of discarding their products in public waste collection systems, including litter waste ones. An appropriate output-based cost model requires assessing TPF quantities in relevant waste streams. Currently, there is no comprehensive data available on TPF quantities in municipal solid waste (MSW). Therefore, a case study was conducted to quantify TPF in MSW. This study aimed to determine TPF quantities (1) in residual waste from four German district types and (2) in waste from public collection systems for three settlement structures within Trier City. Relevant waste streams from public collection systems, namely waste from public waste receptacles, street-cleaning waste and sinkhole residues, were identified. For both sampling campaigns, consideration was given to extrapolating the results to a larger scale. The results showed that the average specific TPF quantities in residual waste were 277.7, 271.8, 193.3 and 204.5 gi- 1a- 1 in the selected city district, urban district, densely populated rural district and sparsely populated rural district, respectively. Extrapolation of these results to Germany yielded a specific TPF quantity in residual waste of 250.3 gi-1a-1. The average specific TPF quantities in waste from public waste receptacles, street-cleaning waste and sinkhole residues were 12.2, 47.4 and 9.9 gi-1a- 1, respectively.

A total of 56 studies were compiled that included laboratory-, pilot- and landfill-scale hydraulic conductivity experiments. Compacting waste and increasing vertical stress reduce MSW hydraulic conductivity via reshaping the pore networks throughout the waste matrix, reducing the void ratio and increasing tortuosity. However, the magnitude of reduction in hydraulic conductivity is dependent on stress, waste composition and decomposition. Solid waste decomposition can have opposing effects on hydraulic conductivity. Some studies have indicated that an increase in MSW decomposition results in particle size reduction and settlement that reduces the void ratio and decreases hydraulic conductivity. Conversely, some studies indicate that waste decomposition reduces the solid mass, which increases the void ratio and creates larger flow paths that increase hydraulic conductivity. The data compilation, observations and key findings from this study are beneficial for solid waste practitioners to improve design, analysis and operation of MSW landfills.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"997-1007"},"PeriodicalIF":3.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11531081/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138446312","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}

To describe the problem created by COVID-19 HCW, first, the subsystems of the overall management system, including generation, segregation, classification, storage, collection, transport, treatment and disposal, were reviewed and briefly described. Then, the CE hierarchy using the 10R typology was adapted to the management of COVID-19 HCW and included the strategies Refuse, Reduce, Resell/Reuse, Repair, Reprocess, Refurbish, Remanufacture, Repurpose, Recycle and Recover (energy). Disposal was added as a sink of residues from the CE strategies. Using the detailed 10R CE hierarchy for COVID-19 HCW management is the novelty of this review. It was concluded that R-strategy selection depends on its position in the CE hierarchy and medical item criticality and value. Indicative HCW components, which can be managed by each R-strategy, were compiled, but creating value by recovering infectious downgraded materials contaminated with body fluids and tissues is not currently possible. Therefore, after applying the circular solutions, the end of pipe treatment and disposal would be necessary to close material cycles at the end of their life cycles. Addressing the risks, knowledge gaps and policy recommendations of this article may help to combat COVID-19 and future pandemics without creating environmental crises.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"977-996"},"PeriodicalIF":3.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41152749","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}
