Carbon reduction at the source! “Ultra-low-carbon” primary aluminum and the addition of secondary aluminum are simultaneously promoted, Budweiser and Ball minimize the carbon footprint of aluminum cans

Quote 罐言罐语

 In the past year, the beer giant Anheuser-Busch InBev and one of the world’s canning giants, Ball, has successively promoted the use of aluminum made of “ultra-low carbon” primary aluminum in the European and American markets through cooperation with aluminum companies such as Rusal and Rio Tinto. Cans, supplemented by the application of recycled aluminum components, significantly reduce CO2 emissions during the life cycle of aluminum packaging.

Nowadays, the weight of aluminum can becomes more and more light based on higher technic based can making machine. Light weight means the less thickness.  When using the light aluminum can,  one kind of gas dosing in cans to make the cans as strong as it can be. The gas is nitrogen.  Liquid nitrogen dosing machine also play an role in Carbon Reduction.

From the perspective of several world-class aluminum giants, in the production of primary aluminum, there are generally two ways to reduce or even eradicate greenhouse gas emissions: one is to use renewable energy such as hydropower in the smelting process; the other is to use subversive The zero carbon-emission conductive materials with innovative significance, such as inert anode electrolysis technology, only produce oxygen during the electrolysis process, unlike traditional carbon anodes that produce CO2. The result of the two-pronged approach is said to be an 85% reduction in carbon emissions compared to the conventional electrolytic aluminum process.


Anheuser-Busch InBev cooperated with RUSAL to launch aluminum cans and canned beer with the smallest carbon footprint in Europe


Anheuser-Busch InBev claims that packaging-related carbon emissions contribute the most to the carbon emissions of its product value chain. Therefore, the company has been reducing carbon emissions in the packaging supply chain by using sustainable packaging such as low-carbon aluminum and lightweight glass bottles.

Comprehensive press releases and media reports, in August 2021, through a joint venture known as the world’s largest low-carbon aluminum supplier, namely, RUSAL, the metal business unit of the EN+ Group, beverage can manufacturer Canpack, and a professional aluminum coil rolling company Elval, Anheuser-Busch InBev announced in the United Kingdom that it has started a trial of 5 million 440ml “ultra low carbon” aluminum cans. It is said that this is the smallest carbon footprint aluminum can launched by the company in Europe. The specific performance is in the following four aspects .

AB-Inbev UK cooperated with Rusal to produce 5 million 440ml aluminum cans using ultra-low carbon aluminum technology, which is said to be the smallest carbon footprint aluminum can launched by the company in Europe.

The disruptive and innovative inert anode electrolysis technology reduces CO2 emissions from primary aluminum production by 85%. First of all, the aluminum ingot comes from RUSAL’s ultra-low carbon primary aluminum “Allow Inerta” produced based on its disruptive and innovative CO2-free inert anode electrolysis technology and renewable energy. It is said that the carbon emissions of this electrolysis process are only the industry average. One-thousandth of the level has caused Allow Inerta’s greenhouse gas emissions from the bauxite mine to the smelting workshop to drop by 85% compared to the industry average.

As we all know, the traditional primary aluminum smelting process is to put a carbon anode in an electrolytic cell containing alumina and other materials, and then apply a strong current to the electrolytic cell to produce aluminum. At present, aluminum companies including Rusal, Rio Tinto, and Alcoa are developing advanced conductive materials with zero CO2 emissions.

According to Greg Barker, CEO of Rusal’s parent company En+ Group, this is the first time that Rusal has produced aluminum products with nearly zero carbon emissions on such a large scale. According to the “Financial Times” report, Rusal’s signing of the deal coincided with the EU’s preparation of a “carbon border adjustment tax” on a series of products, including imported steel, aluminum, fertilizer and cement. Including RUSAL’s ALLOW, the currently available low-carbon aluminum brand metal raw materials are all produced in aluminum smelters that use hydroelectric power. The current R&D focus is on more environmentally friendly alumina treatment methods.


The can material alloy contains recycled aluminum. Secondly, the aluminum in the aluminum can starts with Allow Inerta and is added with recycled aluminum.


Renewable energy is used in the can making process. Third, the aluminum cans are manufactured by Canpack UK using 100% renewable electricity.


The procurement of local raw materials and the application of renewable energy have further reduced carbon emissions in the beer brewing process. Fourth, the beer in this batch of ultra-low-carbon aluminum cans is brewed using 100% renewable electricity and raw materials sourced locally in the UK. It is reported that since January 2021, the British company Budweiser has begun to use 100% renewable electricity including wind and solar energy in the country. At the same time, with the implementation of the British barley brewing plan, the transportation process has been further reduced Carbon emissions.


The above combination allows Budweiser UK’s aluminum cans in Europe to achieve the smallest carbon footprint. Coupled with aluminum’s inherent almost infinite cycle of continuous carbon reduction advantages, it depicts consumers with low-carbon, sustainable packaging. The future.


The appearance and touch of ultra-low carbon aluminum cans are said to be the same as existing conventional aluminum cans. More importantly, through the cooperation of the entire value chain, the traceability of raw materials for aluminum cans has been achieved.


Budweiser stated that consumers are concerned about climate change, so the company hopes to make it as convenient as possible for consumers to make environmentally friendly choices in their daily lives-whether it is using 100% renewable electricity and brewing beer from locally sourced raw materials, Still low-carbon aluminum cans.



Constantly seek new ways to reduce carbon across the value chain to achieve the goal of “25% carbon reduction by 2025″. Anheuser-Busch InBev’s sustainability goal is to reduce carbon emissions in the value chain by 25% by the end of 2025. Judging from its actions in the past year, it is constantly seeking new ways to reduce carbon across the value chain, including improving the sustainability of packaging to achieve its ambitious sustainability goals.


Specifically in terms of the packaging sector, in addition to the aforementioned low-carbon aluminum cans, the company has also made gains in the field of low-carbon glass bottles. In June 2021, Anheuser-Busch InBev launched a new lightweight long-necked glass beer bottle with a weight reduction of 30g, which is said to have reduced its carbon footprint by 17% compared to other glass bottles. Anheuser-Busch InBev plans to promote the use of this new light-weight glass beer bottle in its branded glass beer products across Europe. Once the plan is implemented, the annual carbon emission reduction is expected to be equivalent to that of 62,000 cars driving on the road. Emissions are comparable.

In June of this year, Anheuser-Busch InBev launched a new light-weight long-necked glass beer bottle with a weight reduction of 30g.


Anheuser-Busch InBev cooperates with Rio Tinto to launch low-carbon aluminum cans that reduce carbon emissions by 30% in North America


As early as October 2020, Rio Tinto announced that it had signed a memorandum of understanding with AB InBev, promising to work with supply chain partners to use low-carbon aluminum that meets industry sustainability standards in the North American market. The beer is packaged in aluminum cans. The first batch of 1 million cans has been tested on Michelob ULTRA, the fastest-growing beer brand in the United States.


The first batch of 1 million low-carbon aluminum cans jointly developed by Anheuser-Busch InBev and Rio Tinto has been tested on Michelob ULTRA, the fastest-growing beer brand in the United States in 2020.

According to the agreement, Anheuser-Busch InBev will use Rio Tinto’s aluminum based on renewable hydropower and add recycled aluminum to make more sustainable aluminum cans. Compared with other aluminum cans manufactured using traditional production methods in North America, the carbon emissions will be reduced by 30%. %above. In addition, this cooperation will also introduce the development results of Rio Tinto and Alcoa’s (Alcoa) joint venture ELYSIS, which is supported by Apple and the governments of Canada and Quebec, which is a disruptive zero-carbon aluminum smelting technology.


The Budweiser InBev aluminum cans produced in the North American market are said to contain 70% recycled aluminum. The application of low-carbon aluminum will enable the company to take a critical step towards reducing carbon emissions in the packaging supply chain. Rio Tinto expects that the cooperation with AB InBev will continue to lead responsible aluminum production, impart transparency and traceability to the entire supply chain, and meet consumers’ expectations for sustainable packaging. In short, the two parties will work together to introduce innovative technological solutions to AB InBev’s supply chain, push it to shift to more sustainable packaging, and provide traceability for aluminum in cans.

Ball and RUSAL cooperate to launch “ultra-low carbon” aluminum blocks and IE aluminum packaging, adding power to ReAl’s sustainable packaging platform


In July 2021, Ball of the United States and Rusal announced an exclusive cooperation to produce aluminum blocks and impact extrusion (IE) containers based on inert anode electrolysis technology and “ultra-low carbon” aluminum materials smelted from renewable energy. As mentioned earlier, compared to conventional carbon anode electrolysis technology, it is said that it can reduce CO2 emissions by 85%.


The original Ball’s own ReAl sustainable packaging platform already has sustainable packaging bonus points that reduce packaging weight and contain recycled aluminum. Now the addition of “ultra-low carbon primary aluminum” materials will further significantly reduce the aluminum packaging life cycle Of CO2 emissions.

With the exclusive cooperation between Ball and RUSAL, its own ReAl sustainable packaging platform now integrates the sustainable advantages of packaging weight reduction, containing recycled aluminum components, and ultra-low carbon primary aluminum.


As Sylvain Brisseau, the company’s vice president of aluminum technology, said, Ball and its suppliers have the lofty ambition to “continue to push the boundaries of aluminum packaging innovation.” Blocks, aluminum cans and aluminum bottles are one of the several means of carbon footprint of products. Ball looks forward to obtaining a responsible supply of materials through close cooperation with suppliers such as Rusal.


Ball and Rusal are both members of the Aluminium Management Initiative (ASI), a non-profit organization. ASI is said to involve multiple stakeholders and is committed to promoting the sustainable development of the global aluminum industry.

Concluding remarks


Relevant data shows that 75% of the aluminum produced by mankind in history is still recycled. With its own value and the advantages of infinite circulation without quality loss, aluminum is recognized as one of the most suitable materials for circular economy. As the demand for aluminum packaging grows, the upstream and downstream of the industry chain should focus more on how to reduce the environmental and social impacts related to the supply of aluminum materials to meet consumers’ increasing emphasis on corporate procurement for more sustainable packaging and bulk raw materials.
