  • environmental and economic life cycle assessment of Aluminum silicon alloys production a case study in china
    Journal of Cleaner Production, 2012
    Co-Authors: Jing Min Hong, Jinglan Hong, Jing Zhou, Xu Xu

    Abstract:

    Abstract A coupled life cycle costing and life cycle assessment was carried out to estimate the economic and environmental impact of silicon-Aluminum alloy production. The results showed that the Aluminum alloy made from secondary Aluminum accounted for 70%–95% of the environmental benefits in most categories, except in the land occupation and economic categories, compared with the Aluminum alloy made from primary Aluminum. These findings could be attributed to the decrease in energy and raw material consumption (i.e., electricity, sodium hydroxide, petroleum coke, and charcoal consumption) and the relatively high cost of secondary Aluminum Scrap. Optimizing raw material and electricity consumption efficiency, decreasing the transport distance from raw material (e.g., bauxite and old Aluminum Scrap) buyers to suppliers, and changing the end-life treatment of red mud from landfill to road building material production are key factors in reducing the overall environmental and economic impact.

  • Environmental and Economic Assessment of Recycled Aluminum Alloy Production – A Case Study of China
    Advanced Materials Research, 2010
    Co-Authors: Jing Min Hong, Zainab Z. Ismail, Jinglan Hong

    Abstract:

    A life cycle assessment was carried out to estimate the environmental and economic impacts of recycled Aluminum alloy production. The impact seen from non-carcinogens, respiratory inorganics, terrestrial ecotoxicity, global warming and non-renewable energy categories played an important role to overall environmental impacts. The impact seen from carcinogens and aquatic ecotoxicity played relatively small role, while the impact seen from the rest categories affect the environment was ignorable. Specifically, the emissions from the Aluminum and silicon production stages involved played an important role due to high energy consumption, while potential impact generated from other elements was quite small. Similarly, the cost of old Aluminum Scrap represented the dominant contribution to overall economic impacts. Accordingly, choosing natural gas based electricity production technology and improving old Aluminum Scrap consumption efficiency are the efficient way to minimize the overall environmental and economic impact, respectively.

  • Analysis of the Behavior of Local Cooking Utensils in Tap Water, Salt Tap Water and Vegetable Oil According to the Temperature
    , 2013
    Co-Authors: Mamadou Babacar Ndiaye, Sandrine Bec, Bernard Coquillet, Ibrahima Khalil Cissé

    Abstract:

    In Senegal the Aluminum Scrap are mainly recycled kitchen utensils [1]. The craftsmanship poses the problem of the quality of finished products [1] especially when we know they are used for everyday cooking. Given that none of these alloys should not be used to make cooking utensils if we refer to the EN 601 standard in July 2004, which refers to this regard [1], this study aims at analyzing behavior of these alloys reconstructed in three settings (tap water, vegetable oil and salt water more than 3 grams per liter), chosen for their importance in Senegalese cuisine. Significant loss of mate- rial was observed mainly by intergranular corrosion. It would be interesting that additional studies be conducted to ex- amine the impact of the daily use of these alloys on the health of Senegalese.

  • Analysis of Cooking Utensils Containing Aluminium Scrap in Senegal
    , 2012
    Co-Authors: Mamadou Babacar Ndiaye, Sandrine Bec, Bernard Coquillet, Ibrahima Khalil Cissé

    Abstract:

    The purpose of this study is to analyze the metallurgical quality cooking utensils containing Aluminum Scrap in Senegal. Indeed, in this country, the recycling of metallic materials is a very interesting income generating activity. A whole chain, from collection to revaluation, has been set up and operate this vein with the support of partners, for the most foreigners. For Aluminum Scrap mostly issued from the automotive industry, they are essentially recycled in cooking utensils by the technique of molding sand. A study was then proposed to analyze the reconstituted Aluminum alloy, the artisan technique and the quality of final products. This first part focuses on the quality of alloys and their mechanical properties. The results show that all the alloys have levels higher than the maximum allowed by the standard NF EN 601 (July 2004). They also proven that the finished products have a high porosity due to the low amount of water control and linked to the quality of sand. That’s why our analysis allowed to propose a change in preventive than half of the sand every three (03) months.
