It could also enable built environment sectors like rail infrastructure to operate and provide value for society more sustainably. However, while various strategies could support the CE transition, there is little evidence of their implementation for rail infrastructure to date. Also, despite growing research addressing CE practice in the built environment sector, most articles rely on secondary data. There is a need for more research based on primary data to bring new insights and guide the industry towards CE implementation. This research investigates the importance of CE implementation strategies, barriers and enablers for UK rail infrastructure projects through an industry-wide survey. It discusses the findings of an online questionnaire (<em>n</em>=50) and 15 semi-structured interviews with representatives from UK rail industry organizations. The results generally show rail infrastructure as being less commercial, but also more permanent, risk-averse and resistant to change. As such, value optimization and life extension should be more relevant than for buildings. However, greater resistance to change may hinder CE implementation, which is seen as requiring a paradigm shift away from the current linear model of consumption. Client leadership will be key in this respect, because of their scale, influence and long-term responsibility for asset ownership, but they may require support from government to overcome various structural factors. Government could also help by setting CE procurement requirements in contracts for rail infrastructure projects.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"21 ","pages":"Article 200195"},"PeriodicalIF":0.0,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667378923000676/pdfft?md5=386c228a327db4a180914825fa38802d&pid=1-s2.0-S2667378923000676-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139297891","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}

To manage groundwater resources in a sustainable manner, proper monitoring, regulation, and conservation strategies are required. Groundwater contamination in India is growing as a result of population increase and industrialisation, which can have serious health and environmental consequences. To avoid groundwater pollution, it is critical to monitor and control possible sources of contamination, as well as to promote sustainable farming practices and the use of less hazardous pesticides and fertilizers. To get a better knowledge of groundwater pollution, the current study attempted to analyse the quality of groundwater in the neighbourhood of the Vellalore dump yard (located in Coimbatore, India), encompassing an area of 161.87 hectares. To examine the quality of groundwater in the contaminated region, several physical and chemical properties such as pH, dissolved oxygen, total dissolved solids, and water quality index were measured. The majority of the water samples from the region are classed as low quality and unsafe for drinking. The plume appears to be migrating northerly and northwest from the landfill location, most likely due to the natural slope of the dump site towards the northwestern direction. The bulk of the gathered samples have low water quality, making the water unfit for even basic residential use. These findings highlight the need of local governments taking proactive efforts to protect the groundwater in this area, pushing for a comprehensive approach to prevent additional pollution. The report emphasizes the critical need for local governments to take prompt action to prevent additional groundwater pollution by establishing a comprehensive strategy.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"20 ","pages":"Article 200196"},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667378923000688/pdfft?md5=03aca47cf281392a1e913c334c4c1ab5&pid=1-s2.0-S2667378923000688-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138430740","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 an emission-reduction framework to assess the economic benefit of sustainable MSW management in Sub-Saharan Africa (SSA) over a 60-year period (2000–2060). Two waste-to-energy (WTE) methods, sanitary landfills and anaerobic digestion, were used to assess the potential electricity generation from MSW under four waste collection scenarios. The assessment was compared to the potential economic damage from cumulative methane (CH4) emissions under business-as-usual waste management practices for the same period. The results show that energy recovery from current MSW generation forecasts can contribute to 100–245 kWh per capita electricity generation between 2025 and 2060, depending on the WTE technology employed. The net present value (NPV) of WTE technologies is less than half the dollar cost of the potential economic damage from methane emissions. These results have significant policy implications for increasing access to sustainable and clean energy in SSA countries. Given that the current average per capita electricity generation in SSA is 158 kWh and that several countries in the area are experiencing energy problems, MSW electricity generation offers untapped economic development prospects. These findings highlight the economic advantages of effective waste management in SSA to mitigate future environmental and climate change consequences of greenhouse gas emissions. Furthermore, this study underscores the need for stakeholders to develop cost-effective and sustainable waste management strategies to avoid possible future economic and environmental damage in SSA.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"20 ","pages":"Article 200192"},"PeriodicalIF":0.0,"publicationDate":"2023-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667378923000640/pdfft?md5=f38e0f23cc6b6cf4a91cecf0a40b1fe6&pid=1-s2.0-S2667378923000640-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138335249","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}
