Rich in biodegradable compounds like carbohydrates, proteins and lipids, organic waste is suitable for biological conversion, including anaerobic digestion and dark fermentation (DF), enabling biohydrogen (bioH₂) production. Pretreatment of organic waste is a key strategy to enhance substrate biodegradability and improve hydrogen yields in DF. This review provides a comprehensive assessment of chemical, physical, biological and integrated pretreatment methods applied to organic waste, summarizing recent advancements and evaluating their effectiveness in maximizing bioH₂ production. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology was applied to ensure transparent selection of peer-reviewed studies on organic waste pretreatment for hydrogen generation. A comparative analysis has been carried out on the selected studies to highlight the impact of operational parameters and pretreatment strategies on hydrogen production processes, aiming to evaluate their influence on specific hydrogen production, helping to identify current trends and providing a useful reference for assessing process efficiency. Evidence from our comparative analysis identifies thermal pretreatments as the most effective for food waste, reaching a hydrogen yield over 300 mL H₂/g VS₀. Finally, this review outlines emerging perspectives on the optimization of pretreatment strategies aimed at enhancing biohydrogen production. Overall, the findings provide a valuable reference and decision-support framework for researchers, engineers and stakeholders working to advance sustainable hydrogen production from organic waste within the circular economy and energy transition contexts.</p>","PeriodicalId":520825,"journal":{"name":"Waste management & research : the journal of the International Solid Wastes and Public Cleansing Association, ISWA","volume":" ","pages":"1376-1391"},"PeriodicalIF":4.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147680301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rapid urbanization and increased uptake of disposable hygiene products have outpaced the development of adequate waste management systems, leaving AHPs largely unsegregated, untreated, and unmanaged. This mini-review synthesizes contemporary literature from the Global South to explore the 'costs' associated with three common mismanagement scenarios: co-disposal with household waste, management outside formal systems, and non-management in the environment. Findings reveal that while the spaces of mismanagement are well documented, the costs remain poorly understood, unevenly distributed and often hidden. Co-disposal exacerbates landfill overcapacity, cross-contamination and greenhouse gas emissions; disposal outside waste systems burdens sanitation networks with blockages and infrastructure damage; and non-management disperses risks into public domains, contaminating soils and waterways, shortening pit latrine lifespans and compounding health hazards for households and sanitation workers. Across contexts, these costs are borne disproportionately by vulnerable groups, including women, children, animals, informal waste workers and low-income households, yet remain largely absent from policy debates and product life cycle assessments. Addressing these gaps requires more context-specific case studies, quantification of costs and greater recognition of disposal within sustainability frameworks to ensure equitable and effective interventions.</p>","PeriodicalId":520825,"journal":{"name":"Waste management & research : the journal of the International Solid Wastes and Public Cleansing Association, ISWA","volume":" ","pages":"1436-1444"},"PeriodicalIF":4.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13530355/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147583632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used IBAs from fluidized bed (FB) and grate (G) municipal solid waste incineration for two full-scale experiments, investigating the flows of metallic aluminum in a dry-wet IBA treatment process. Metallic aluminum >4 mm was determined by hand sorting, while <4 mm was determined by the soda-attack method. Extraction rates into metal concentrates of 97% for FB-IBA and 78% for G-IBA were achieved, demonstrating the plant's ability to treat both types of IBA. The elevated extraction rate for FB-IBA is attributable to the dry IBA discharge and the reduced bed temperature. These factors preclude the melting of aluminum, glass, and minerals, resulting in the presence of aluminum particles that are entirely liberated from the mineral phase of IBA, which is advantageous for eddy current separation. Consequently, low residual metallic aluminum contents in the treated mineral fraction (0-8 mm) of 0.5 wt-% in FB-IBA and 1.0 wt-% in G-IBA were determined. Nevertheless, to draw conclusions on the usability in concrete, it is imperative to implement continuous monitoring of the residual metallic aluminum content to substantiate these values, given their reliance on sound plant operation as well as on the initial IBA composition, which knowingly exhibits significant fluctuations.</p>","PeriodicalId":520825,"journal":{"name":"Waste management & research : the journal of the International Solid Wastes and Public Cleansing Association, ISWA","volume":" ","pages":"1460-1471"},"PeriodicalIF":4.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13530342/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147826347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proper landfill siting is therefore essential to minimize environmental and public health impacts. This systematic review evaluated 50 landfill site selection studies (2020-2025) using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. Multi-criteria decision-making (MCDM) techniques dominate, with the analytical hierarchy process applied in 12 studies (24%), while only 8 studies (16%) adopted hybrid models integrating geographic information systems, fuzzy logic, clustering or optimization. A total of 81 criteria were analysed across the studies: topographic factors were used in 84%, hydrological in 78%, geological in 72%, infrastructural in 68%, and socio-economic 56%. However, critical parameters such as soil pH and air quality indices were not applied in any of the studies, and predictive modelling for land-use, population, and household density changes was not implemented. Likewise, remote sensing (RS) applications were rarely used, with Normalized Differential Vegetation Indices and Normalized Difference Built-up Index dominating, while advanced indices such as Modified Normalized Water Index, Modified Soil Adjusted Vegetation Index, and Topographic Wetness Index were used in fewer studies. Furthermore, 84% of reviewed works relied on single models, reflecting methodological conservatism and limited innovation. The findings highlight overdependence on expert judgement, inconsistent regional guidelines and inadequate integration of sustainability-oriented indicators.

The removal of leachate from the waste mass modifies the internal moisture content and generates convective flow, which unavoidably leads to variations in waste temperature. These temperature changes subsequently influence the degradation behaviour of the original waste. In this study, based on the previously completed leachate pumping test, the associated fluctuations in leachate level and waste temperature evolution during the pumping process were simulated. An axisymmetric saturated-unsaturated seepage model was established for high-level landfills, incorporating depth-dependent variations in permeability and porosity. Additionally, an axisymmetric heat convection-conduction model was developed, taking into account both the impact of seepage on temperature distribution and the influence of moisture content on waste degradation. The governing models were solved using numerical calculation methods. Comparisons between the calculated results and test data indicated that the proposed models and solution approach accurately captured the trends in leachate level variation and waste temperature changes induced by leachate pumping. The results suggest that, under single-well pumping conditions, the degradation duration of newly placed waste and the specific heat capacity exerted a relatively pronounced effect on temperature distribution. Waste permeability exhibited a negligible influence on temperature gradients outside the zone of influence; however, it played a decisive role in determining the magnitude of temperature variation within the affected area. The models developed in this study provide a theoretical basis for evaluating temperature distributions under leachate pumping conditions and offer important guidance for landfill operation, expansion and closure.</p>","PeriodicalId":520825,"journal":{"name":"Waste management & research : the journal of the International Solid Wastes and Public Cleansing Association, ISWA","volume":" ","pages":"1556-1574"},"PeriodicalIF":4.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148039207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With rapid urbanization generating over 150,000 tons of MSW daily in India, RDF offers a dual benefit: reducing landfill dependency while providing an alternative fuel. Through an extensive analysis of peer-reviewed literature, government reports, and case studies from Indian and international waste-to-energy (WtE) facilities, this review evaluates current technological approaches, regulatory frameworks, and economic factors influencing RDF adoption in the Indian context. RDF can substitute significant share of fossil fuels in cement kilns and power plants while reducing greenhouse gas emissions compared to conventional landfilling. However, successful deployment faces significant barriers including feedstock heterogeneity, inadequate preprocessing infrastructure, inconsistent emission standards, and limited financial incentives. Addressing these challenges requires coordinated efforts: standardized quality protocols, robust regulatory frameworks, technological innovations for emission control, and policy-driven incentives such as carbon credits and subsidies. The review identifies critical gaps in India's RDF ecosystem and provides recommendations for integrating RDF into circular economy (CE) strategies. Key insights include the necessity of region-specific quality standards, investment in preprocessing infrastructure, and community engagement models that ensure sustainable waste segregation.

As the most visible part of the value chain, the collection system plays a key role in waste management performance. This study quantifies the environmental impacts of various food waste collection methods using life cycle assessment, focusing on climate change and potential trade-offs across other impact categories. Two different treatment alternatives were explored: composting and anaerobic digestion (AD). The functional unit was defined as the management of the average amount of food waste generated per person during a year in Norway. The results show that the collection strategy affects both sorting rate and environmental performance. Climate change impacts range from -9.7 to -7.5 kg CO₂ eq./person/year for AD and between -6.3 and 2.5 kg CO₂ eq./person/year for composting. Collection in paper bags in separate containers results in the lowest climate change impact for both treatment pathways, but may increase other environmental impacts. For the AD pathway, there are relatively small differences between the results for the studied collection options. The use of paper bags, however, is likely to be the only option that eliminates the risk of plastic pollution in the soil from bags.

Most geographic information system (GIS)-based optimisation models remain top-down, failing to reflect on-the-ground realities and are rarely implementable. This study presents a participatory GIS-based routing methodology for decentralised MSWM system in a flood-prone town in Kerala, India.
