Aluminum is the element of possibility.
It is lightweight, durable and infinitely recyclable. It is used to make airplanes, cars, trucks, buses, trains and buildings more energy-efficient, helping reduce greenhouse gas emissions over the life cycles of these products. It enables lighter, fully recyclable food and beverage packaging, thereby reducing waste.
In early 2020, we began selling bauxite, alumina and aluminum that is certified by the Aluminium Stewardship Initiative (ASI).
Gränges is committed to reducing our climate impact from a life-cycle perspective, and thereby enhancing our sustainability performance. One of the key priorities in our climate strategy is to collaborate along the value chain and increase the sourcing and use of recycled aluminum and low-carbon primary aluminum since such materials significantly reduce our products’ carbon footprint. That is why the collaboration with Alcoa creates value.”Sofia Hedevåg

We are the world’s leading producer of alumina outside of China and the world’s largest third-party supplier of alumina, which we produce from a portfolio of refineries that together have the lowest average intensity of carbon emissions in the industry.
In 2020, we introduced the industry’s first low-carbon, smelter-grade alumina brand as part of our Sustana™ line of environmentally friendly aluminum products. EcoSource™ alumina is produced with no more than 0.6 metric tons of carbon dioxide equivalents (CO2e) per metric ton of alumina, which is half the industry average of 1.2 metric tons of CO2e.
Aluminum can be recycled infinitely without losing its properties, making it the sustainable choice in many of the markets we serve. Producing primary aluminum from recycled content consumes about 5 percent of the energy required to make virgin aluminum and avoids up to 95 percent of the energy-related emissions.
At our Poços de Caldas location, we have increased the amount of recycled scrap used in billet production by 200 percent since 2015. This has reduced the plant’s GHG emissions by approximately 30 percent.
