Abstract

The sustainability of using industrial by-products for the construction of landfill cover was determined using Life Cycle Assessment (LCA). LCA was carried out on four materials: sand- bentonite mix, red earth- bentonite mix (amended soil), Waste Foundry Sand (WFS)- Bentonite mix, and WFS- marine clay mix. The former two are commonly used cover soils and the latter two are alternative materials proposed. Environmental impacts based on the extraction of resources, processing, transportation to the site, and site preparation were considered using the ‘cradle to site’ approach. Analysis was carried out in OpenLCA software using the ReCiPe (H) Midpoint method of impact assessment. Required data for analysis was taken from the Ecoinvent database supplemented with inputs from a field survey. The use of WFS in landfill cover systems was found to be sustainable using LCA studies when compared to conventional materials.

通过生命周期评估分析利用回收废料构建的垃圾填埋场覆盖系统的可持续性

利用生命周期评估（LCA）确定了使用工业副产品建造垃圾填埋场覆盖层的可持续性。对四种材料进行了生命周期评估：砂-膨润土混合物、红土-膨润土混合物（改良土壤）、废铸造砂（WFS）-膨润土混合物以及废铸造砂-海洋粘土混合物。前两种是常用的覆盖土，后两种是建议的替代材料。采用 "从摇篮到现场 "的方法，考虑了资源提取、加工、运输到现场以及现场准备对环境的影响。采用 ReCiPe (H) 中点影响评估方法，在 OpenLCA 软件中进行了分析。分析所需的数据来自 Ecoinvent 数据库，并辅以实地调查的输入数据。通过生命周期评估研究发现，与传统材料相比，在垃圾填埋场覆盖系统中使用 WFS 是可持续的。

期刊介绍： The journal was established initially by the name of Journal of Environment and Pollution in 1994, whose name was later changed to Nature Environment and Pollution Technology in the year 2002. It has now become an open access online journal from the year 2017 with ISSN: 2395-3454 (Online). The journal was established especially to promote the cause for environment and to cater the need for rapid dissemination of the vast scientific and technological data generated in this field. It is a part of many reputed international indexing and abstracting agencies. The Journal has evoked a highly encouraging response among the researchers, scientists and technocrats. It has a reputed International Editorial Board and publishes peer reviewed papers. The Journal has also been approved by UGC (India). The journal publishes both original research and review papers. The ideology and scope of the Journal includes the following. -Monitoring, control and management of air, water, soil and noise pollution -Solid waste management -Industrial hygiene and occupational health -Biomedical aspects of pollution -Toxicological studies -Radioactive pollution and radiation effects -Wastewater treatment and recycling etc. -Environmental modelling -Biodiversity and conservation -Dynamics and behaviour of chemicals in environment -Natural resources, wildlife, forests and wetlands etc. -Environmental laws and legal aspects -Environmental economics -Any other topic related to environment
