This study, conducted on a construction site in Morocco, a country still underrepresented in sustainable development initiatives, examines the implementation of an EMS compliant with ISO 14001:2015. The underground gallery construction site, located in the Sidi Bernoussi area of Casablanca, aims to collect rainwater. It is managed by CAPEP, a Moroccan company specializing in public works and construction. This research stands out for its contextual approach, filling a significant gap regarding the practical application of international environmental management standards on a Moroccan construction site. The study is based on comprehensive data collection to identify and assess the main environmental aspects and impacts of the project, using a methodology based on severity, probability, and control criteria. Based on the results, an environmental action plan was implemented to optimize the management of solid and liquid waste. This plan has improved waste separation at the source, increased solid waste recovery by 30 %, and reduced disposal costs. Awareness and training programs were established to encourage more efficient practices in resource and waste management. The practical impact of this research lies in the clear demonstration of the benefits of an EMS in improving the environmental performance of construction projects in Morocco. Furthermore, this study offers specific recommendations, such as improving manager training, to encourage other companies in the sector to adopt similar practices, thus strengthening the environmental governance of the construction industry.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100259"},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679685","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}

Also, BIM can support the project's sustainability within the design and pre-contract stages to mitigate construction waste (CW). Therefore, this study investigates Building Information Modelling’s (BIM) effectiveness in mitigating CW in Nigeria’s construction sector, particularly during design and pre-contract stages. It seeks to identify key contributing factors to CW and explore BIM’s potential in addressing these issues. Utilizing a comprehensive literature review, the research identified 37 potential CW causes, incorporating them into a survey for construction professionals. As a result, 133 valid responses were collected and analyzed by using different statistical techniques, including normalized mean technique, quartile analysis, overlapping analysis, contextual disparities analysis, and Spearman’s correlation analysis. The analysis pinpointed 16 critical causes of CW. Significantly, “design complexity”, “errors in contract documents”, “frequent design changes”, and “slow drawing revision and distribution” were identified as paramount. The comparison with previous studies underscores how addressing the critical causes of CW using BIM can contribute to sustainable construction practices. In all, the findings provide valuable insights for mitigating CW in Nigeria and similar contexts in developing economies. Similarly, it can also guide international efforts to reduce CW in construction sectors globally, encouraging countries to address similar critical causes of CW using BIM sustainably. The study advocates for BIM’s early adoption in construction projects to proactively tackle design-related waste.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100252"},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679745","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}

The severity of the landfill scarcity is highlighted in the Cities of Johannesburg and Cape Town, the economic hubs of provinces which together account for 48% and 53% of South Africa’s GDP and construction activities respectively but have less than 5 years of landfill airspace. Findings further reveal that CDW data is not up-to-date and largely underreported due to the omission of informal waste management practices from official statistics, the complexity of the construction industry, the authorities' ineffectiveness, and the lack of measurement mechanisms and infrastructure. The challenges and strategies implemented to improve CDW management such as recycling, recovery, government fiscal incentives and legislation are highlighted and benchmarked against selected countries and regions of the world, aiming to identify strengths and weaknesses, and subsequently adopt international best practices.

In 2024, a survey was conducted among students at the University of Debrecen, the second largest university in Hungary, to assess their knowledge and habits related to food waste. The survey was voluntary and included 133 questions in several groups of questions. After data cleaning, we prepared our study based on the responses of 618 students. The study used variable clustering and explanatory bifactor analysis to identify and create latent constructs related to food waste behavior. Differences in these constructs were examined using the Kruskal-Wallis and Mann-Whitney tests, while K-means clustering and factor analysis of mixed data were applied to analyze demographic influences. All analyses were performed in R. The results show significant differences in food waste behavior based on age, gender, and residential location. Older students (31–40 years) showed higher levels of environmental awareness and were less likely to waste food compared to younger students (under 20 years) who showed higher levels of impulse buying and carelessness, mainly influenced by promotions. Rural students showed more sustainable behaviors, likely influenced by traditional practices such as animal husbandry, while urban students showed greater susceptibility to promotions and discounts, leading to more food waste.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100256"},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637749","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}

The adsorbent was produced by thermal treatment method at 750ºC with 30 min reaction time. The particle size, surface functional group, and surface morphology of the adsorbent were investigated using a laser particle size analyzer, FTIR spectroscopy, and FESEM imaging.

The removal efficiency of real textile wastewater quality parameters was found between 88.68–94.69 % by 1:1 adsorbent. The 1:1 adsorbent brought the highest adsorption capacity of 502.45 mg g⁻¹ for MB. The adsorption kinetic model was more favorable with the Elovich model. The Van Krevelen diagram showed that PCTW and JSW waste biomass had the potential to be used for bioenergy production. The elemental analysis revealed that biomass had an energy value in the range of 14.70–15.54 MJ kg⁻¹. The Tanner diagram displayed that biomass had self-supporting incineration properties.
