The mining sector worldwide has sought to introduce it too, for making its operations environment friendly. India, which is endowed with a multitude of minerals, is also undergoing this course correction. Using conceptual content analysis, the paper attempts to analyse the extent to which mining companies in India are adopting the principles of CE in their operations, in terms of the presence of words associated with CE in their reports. The analysis is done for 13 selected mining companies based on the quantum of their mineral production, from 2018–19 to 2023–24. The paper draws out the various contexts under which the mining companies are considering the notion of CE. Overall, the mention of CE-oriented words in the reports is found to be more implicit than explicit, broadly associated with emissions, inputs, or waste. Input recycling, resource recovery and reuse, mine water treatment and water conservation, and emissions mitigation hold primacy as reasons for adopting CE. Recovery of utilised resources for reuse is seen to be an important area of consideration for the companies, which indicates that they recognise and are keen to address the resource scarcity problem. The obtained results are indicative of the progressive focus of the Indian extractive industry on the adoption of CE practices in its mining-related operations, aimed significantly towards ensuring environmental sustainability, with an additional emphasis on societal benefits.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100287"},"PeriodicalIF":0.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844163","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}

It is part of an organizational context that encourages the adoption of these methods and processes. This study aims to improve the use of locally available materials, particularly soil and agricultural residues, in the Errachidia region (southeastern Morocco). In particular, date palm waste fiber, a widely available agrarian by-product, was incorporated into the soil to develop six different types of stabilized earth bricks with fiber contents of 0 %, 1 %, 2 %, 3 %, 4 %, and 5 %. The aim was to evaluate their thermophysical, mechanical, and capillary water absorption properties. Thermal properties were determined using the highly insulated house method (PHYWE), a specific methodology for assessing thermal properties in a controlled, highly insulated environment. In addition, mechanical measurements were carried out to assess compressive and flexural strength. The results obtained showed that the addition of date palm waste fibers to brick based on soil improves the thermal resistance of the bricks. Flexural and compressive strength increased up to 3 % of fiber content, while a reduction was observed above this value. The 3 % fiber content is optimal for the stabilization of brick based on soil. Then, the increase of fiber content in bricks resulted in an increase in water absorption with a decrease in the density of the bricks. Physical and chemical characterization (XRD, FTIR, SEM, and EDX) of the soil and date palm waste fibers was carried out with geotechnical soil tests. The results obtained showed that the soil studied satisfies the minimum requirements for the production of bricks stabilized by fibers. These bricks can be considered an alternative to conventional bricks in ecological construction.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100283"},"PeriodicalIF":0.0,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143833616","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}

Researchers are increasingly exploring industrial by-products as alternatives to natural materials to protect the environment. Among these, sawdust, typically considered waste, has emerged as a potential resource for sustainable construction. Utilizing sawdust in concrete and bricks can reduce environmental challenges such as greenhouse gas emissions, resource depletion, energy consumption, and contamination while addressing waste disposal issues. Sawdust may be used as a partial substitute for aggregates or cement in concrete. Such utilization benefits from its lightweight properties, improved thermal insulation, and decreased carbon footprint. Despite the merits, however, a detailed appreciation of the real contribution of sawdust-based materials toward reduced natural resource consumption and their more extensive environmental impact remains underdeveloped. This review assesses the most recent studies on the production, properties, and performance of sawdust-based building materials, emphasizing their sustainability for construction purposes. The study is divided into two phases, and the previous findings are compared by identifying limitations, contradictions, and research gaps. It shows technical challenges that must be overcome to maximize sawdust use in eco-friendly building practices. Finally, this paper will attempt to lay down a foundation for sustainable construction by proving the viability of sawdust as a resource-efficient, environmentally friendly material.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100286"},"PeriodicalIF":0.0,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143829866","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}

One of the mitigation methods used is permeable groins to reduce current velocity and control flow patterns. However, the use of conventional materials is often expensive and difficult to obtain. This study tested the effectiveness of permeable groins made from used tires in reducing river erosion. The study was conducted in one of the rivers in Jambi City that experienced severe erosion conditions. Permeable groins were installed on site, and measurements were taken for one month to evaluate current velocity, riverbed elevation, and sedimentation. Arduino was used in this study to measure time-series discharge during the study period. The results showed that the installation of groins from used tires was able to reduce the average current velocity by 35 % and facilitate sediment accumulation of up to 6.16 cm between the groin structures. However, local erosion occurred on the groin piles due to the acceleration of the flow through the gaps, which caused an increase in erosion depth of up to 9.95 cm in some areas. In addition to technical benefits, the use of used tires also helps reduce waste and construction costs, making it an economical and environmentally friendly alternative solution.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100279"},"PeriodicalIF":0.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844166","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}

The generation of solid waste have been increasing in urban areas due to the increasing population and socio-economic development in the urban areas. As such, solid waste management is the most difficult task that many developing and developed countries are facing. Solid waste management using landfill techniques is always required for the sustainable management of solid waste. However, selecting suitable landfill site is challenging as it requires multiple factors from multiple sources. Moreover, a comprehensive approach that considered multiple environmental, social and economic factors and per capita solid waste generation rate is not well known. The objective of this study was to select an economically viable, environmentally sound, and socially acceptable solid waste disposal site for the Assosa municipality using the state-of-the-art-geospatial technologies and multi-criteria approach. The main dataset criteria used for this study include proximity from road, slope, elevation, proximity from surface water, proximity from airport, proximity from fault, geology formation, proximity from groundwater point, groundwater depth, proximity to settlement, soil types, proximity from environmental protected areas, land use/land cover, and wind direction. In addition, interview questioners, and field observations were also used as an auxiliary data source. All the factors were evaluated pertinent to their suitability for landfill sites and weights were assigned for each factor using analytical hierarchy process (AHP) and multi-criteria decision making was used to produce solid waste suitability map for the Assossa town. Accordingly, the result showed that about 9.5 km² (8 %) of the study areas was highly suitable, 18 km² (18 %) was moderately suitable, and 79.5 km² (74 %) of the study area was unsuitable for solid waste landfill. The study results further showed that suitable sites for solid waste dumping are located in the northwestern parts of the town.
