All steps in the aluminium production process, as with all industrial processes, consume energy. Fuel is combusted to mine, move and refine bauxite. Smelters combust fuel within the facility to generate heat for anode baking, casting and supporting operations and fabrication facilities require heat and pressure to form the metal.
Refineries may co-generate electricity for use or export in addition to producing the steam required for the Bayer process.
IAI models 1.5-degree decarbonisation scenario in a bid to drive greater emissions reductions This scenario will guide and inform what industry does – much is currently happening. The International Aluminium Institute (IAI) has modelled a 1.5 Degree Scenario to guide its member’s efforts to meet global climate goals. The modelling ...
This factsheet looks at key statistics in the areas of mining, refining, smelting, and recycling. It compares 2018 figures with the greenhouse gas budget assigned to the aluminium sector under B2DS by 2050. The International Aluminium Institute recently released the aluminium sector’s decarbonisation dataset in line with the International Energy ...
The aluminium industry identifies three areas to reduce greenhouse gas emissions. The report, Aluminium Sector Greenhouse Gas Pathways to 2050, sets out three credible and realistic approaches to emissions reductions for the aluminium industry, in line with the International Energy Agency’s Beyond 2 Degree Scenario. The pathways are based on ...
Guidance to support smelters in conducting PFC measurements. This guidance provides practical information to support smelters in conducting PFC measurements for different objectives, including process improvement, benchmarking and GHG inventory reporting. The IAI’s PFC Working Group developed this guidance to reflect changes in the IPCC’s 2019 Refinement of the 2006 ...
The IKE model developed in this study is the most transparent provincialised model for Chinese power grid available at this time. This study outlines the development of a life-cycle model of Chinese grid power at a national level, further developed at regional and provincial levels to better assess the cradle-to-gate ...
This study assesses the water footprint of hydropower plants with a significant contribution to the electricity supply of aluminium smelters. After agriculture, hydropower is considered to be the next largest water-consuming sector, largely due to evaporation (EV) from the reservoir surface. This study looks at the water footprint of hydropower ...
