The Aluminium Stewardship Initiative (ASI) is initiating a Standards Revision in 2020-2021 to review all of the 6 ASI Documents – Performance Standard and Guidance, Chain of Custody Standard and Guidance, Assurance Manual, and Claims Guide. The revision will include multiple rounds of consultation, with opportunities for all members and stakeholders to have input. The ASI Performance and Chain […]
By John Grandfield, Grandfield Technology. Introduction Climate change has brought the greenhouse gas (GHG) emissions of aluminum smelting into sharp focus. Other important sustainability issues include bauxite residue dam integrity, waste disposal (spent potling, dross, etc.), water consumption, working conditions, biodiversity, etc. In this article, past work to reduce GHG emissions is examined together with […]
Elysis, the joint venture between Alcoa and Rio Tinto, announced that is has successfully produced the first commercial batch of aluminum without any direct carbon dioxide emissions at the Alcoa Technical Center (ATC) in Pittsburgh, PA — using a breakthrough, carbon-free smelting technology. The first purchase of the aluminum was made by Apple — a major […]
UC Rusal plans to install over 20 state-of-the-art dry gas cleaning systems (DGCS) at its smelters by 2025. These advanced systems were developed by the company’s design and scientific divisions and the new equipment will allow the company to capture over 99.5% of hydrogen fluoride and solid fluorides. “This project is truly unique thanks to […]
Elysis, the joint venture between Rio Tinto and Alcoa, marked the start of construction on its Research and Development Center in Saguenay, Canada, where the company will develop and commercialize its inert-anode smelting technology — which is said to be able to eliminate all direct greenhouse gas emissions (GHG) from the aluminum smelting process. Representatives […]
Trimet Aluminium SE began trial operation of its “virtual battery,” a technology aimed at making the energy intensive smelting process more flexible. The aluminum electrolysis process has traditionally required a constant supply of energy to remain stable, but this new approach allows for variations in energy input and more control over the smelting process. “We […]
Emirates Global Aluminium (EGA) achieved the internationally recognized ASI Performance Standard at its Al Taweelah smelter in the United Arab Emirates, demonstrating its commitment to environmental, social and governance performance. EGA is the first company in the Middle East to achieve a certification to the Aluminium Stewardship Initiative (ASI) standard. “People around the world are rightly concerned […]
European Aluminium published a new report, Connecting the Sustainability Roadmap 2025 and the SDGs. The European aluminum industry together with key stakeholders presented its Sustainability Roadmap Towards 2025 in 2015. The scope of the roadmap is broad, encompassing alumina and primary production through to semi-fabrication, end-use products, and recycling. It’s an ambitious program with (both concrete and voluntary) targets […]
Emirates Global Aluminum (EGA) in the United Arab Emirates (UAE) will supply almost all of the carbon dust, produced as a by-product of aluminium smelting, for use as an alternative fuel by the UAE cement industry. Carbon dust is generated during the anode production process. The high carbon content in the dust makes it suitable for […]
