BRAZILIAN ALUMINUM - solutions for sustainable living

BRAZILIAN ALUMINUM SOLUTIONS FOR SUSTAINABLE LIVING 52 THE INDUSTRY’S ENVIRONMENTAL PERFORMANCE  As a comparison, the average in emissions from Smelters in China is 16.50 ton CO 2 e/ton of aluminum as listed in the article “GHG emissions from primary aluminum production in China: Regional disparity and policy implications”, published by Han Hao, Yong Geng and Wen Hang in Applied Energy , Volume 166.  In short, each tone of primary aluminum that is not produced in Brazil and is otherwise produced in China has a footprint 4.7 times higher, which also increases the footprint for the products using it.  The impact of direct emissions (scope 1) on the total emissions for each production step is shown below: % of direct emissions – scope 1 Bauxite mining 96% Alumina refining 98% Primary aluminum production 61% Aluminum processing 80% Aluminum secondary production 95% 5.4 - Water use - 2015 5.4.1 - Total water use - thousand m³ Bauxite mining Alumina refining Primary aluminum production Aluminum secondary production Aluminum processing 45.000 30.000 15.000 0 Source: The sector’s companies
