“…Before normalisation, global warming (GW) and, to a much lesser extent, atmospheric acidification (AA) showed the highest air impacts of all the scenarios due to the emissions of SO2, greenhouse gases (CO2, CO, NOx, CH4) and organic emissions to the air (dioxins and formaldehyde) from steam and electricity production. This finding agrees with previous LCA studies based on energy intensive industries, such as the cement (Ali et al, 2016) and iron industries (Li et al, 2016). Eutrophication (EU) and aquatic oxygen demand (AOD) have the largest impact to the water environment in all of the scenarios due to the water emissions of inorganic (ammonia, phosphate) and organic compounds (methanol, phenol) during the production of electricity and the manufacturing processes of Na2CO3 and HCl.…”

Our current economic model is experiencing increasing demand and increasing pressure on resource utilisation, as valuable materials are lost as waste. Moving towards a circular economy and supporting efficient resource utilisation is essential for protecting the environment. The chlor-alkali industry is one of the largest consumers of salt, and efforts have been made to reduce its electricity use. Furthermore, KCl mining wastes have received increasing attention because they can be transformed into value-added resources. This work studies the influence of using different salt sources on the environmental sustainability of the chlor-alkali industry to identify further improvement opportunities. Rock salt, solar salt, KCl waste salt, vacuum salt and solution-mined salt were studied. Membrane cells in both bipolar and monopolar configurations were studied and compared to the emergent oxygen-depolarised cathode (ODC) technology. Life cycle assessment (LCA) was applied to estimate the cradle-to-gate environmental impacts. The natural resource (NR) requirements and the environmental burdens (EBs) to the air and water environments were assessed. The total NR and EB requirements were reduced by 20% when vacuum salt was replaced with KCl. Moreover, the environmental impacts estimated for the monopolar membrane using KCl were comparable to those generated for the bipolar membrane using VS. The difference between the monopolar and bipolar scenarios (17%) was slightly higher than that between the bipolar and ODC technologies (12%). This work demonstrates the importance of studying every life cycle stage in a chemical process and the environmental benefit of applying a circular economy, even in energy intensive industries such as the chloralkali industry.

Cement manufacture is a considerable industrial activity in terms of its volumes and contribution to greenhouse gas emissions. This study apprises the environmental impact of the clinker and Portland cement production in Iran, using life cycle impact assessment. Data used in the cement manufacture life cycle inventory are based on site surveys of energy consumption, raw material use, and transportation distances. Emissions were estimated based on U. S. EPA emission factors. Most of these pollutants were belong to kiln, preheater and diesel fuel, respectively. To a comprehensive impact assessment, some impact and damage categories based on CML baseline, Pfister et al 2009, IMPACT 2002+, cumulative exergy demand (CExD), and Eco‐indicator 99 methods were investigated. Environmental hotspots in all categories were detected. Production process was identified as a substantial contributor in most of the categories, such as global warming impact category and damage to human health. Electricity was the other main contributor. It had the highest share in the total of CExD indictor. Iron ore had the enormous contribution in the impact categories of mineral extraction. In this article, water scarcity footprint for cement manufacture was also investigated. It was concluded that diesel is the main impact categories related to water scarcity indicator. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1901–1907, 2018

“…This proposed building will undergo an integrated study to assess the LCA and EP using the BIM method. Turning into the LCA study, Ali et al [31] and Al-Ghamdi [32] have introduced a comparison between the LCA software. The two studies have mentioned that the PRe SimaPro is a complex analysis tool and an advanced skill level due to a comprehensive comparison.…”

The main goal of this study is to undertake the three methods of life cycle assessment (LCA), the environmental performance (EP), and the building information modeling (BIM) to determine the environmental performance and impacts of two window frame materials: aluminum and wood. This study has been carried out in a proposed project at the Assiut University campus. The LCA has been conducted by assessing materials and processes involved in manufacturing the two window frame types using the SimaPro. The LCA scope of this research covers from cradle to the gate with a designated system boundary. The network flow has been drawn to produce one kilogram of aluminum and wood; the quantities data were gathered from the BIM (using Autodesk Revit). Selecting the database is carefully picked from the Ecoinvent dataset to be closer to Egypt's manufacturing processes. Afterwards, the IMPACT 2002+ with midpoint and endpoint calculations has been used. Finally, the LCA results have been compared with the EP results (using DesignBuilder) to determine the best choice between the two materials. The integration analysis shows that the aluminum industry has higher negative environmental impacts and environmental performance than the wood industry. The total midpoint results of the two materials are found to be 29.6 for aluminum, and 2
