The production of green aluminium involves several innovative techniques designed to reduce environmental impact. One of the most significant advancements is low-carbon aluminium smelting. This process replaces traditional carbon-intensive methods with alternatives that use renewable energy sources, such as hydropower and solar energy. By doing so, the carbon footprint of aluminium production is significantly reduced. 

Another key component in green aluminium production is recycling. Recycled aluminium requires only 5% of the energy needed to produce new aluminium, making it an incredibly efficient and sustainable option. The industry is increasingly focused on maximizing the use of recycled content in aluminium products, further enhancing the environmental benefits. 

The production process also emphasizes closed-loop systems, where waste and by-products are reused within the production cycle. This not only minimizes waste but also reduces reliance on raw materials. For metal industry professionals, understanding these processes is crucial for adapting to the demand for green metals and implementing sustainable practices in their operations. 

Green aluminium in the market 

The market demand for green aluminium is on a steady rise, driven by environmental concerns and regulatory pressures. Consumers and businesses are increasingly prioritizing sustainability, leading to a surge in demand for low-carbon aluminium products. This trend is particularly evident in industries such as automotive, construction and packaging, where the push for eco-friendly materials is strongest. 

The growth of the green aluminium market presents numerous opportunities for buyers, traders and manufacturers. For those willing to invest in sustainable practices, the potential for market expansion and competitive advantage is substantial. Companies that can offer certified green aluminium products are well-positioned to capture the growing demand from environmentally conscious customers. 

However, navigating the green aluminium market can be challenging due to the complexities of certification and the need for transparent supply chains. Industry professionals must stay informed about market developments and regulatory requirements to effectively capitalize on this burgeoning trend. 

Environmental benefits of green aluminium 

By reducing reliance on fossil fuels and minimizing waste, green aluminium plays a crucial role in reducing carbon emissions and combating climate change. This aligns with global efforts to achieve net-zero emissions by mid-century, a goal that is increasingly becoming a priority for governments and businesses worldwide. 

Green aluminium also contributes to resource conservation by promoting the use of recycled aluminium. This not only reduces the need for raw material extraction but also minimizes the environmental impact associated with mining activities. The shift towards a circular economy, where materials are reused and recycled, is essential for sustainable development. 

For companies committed to sustainability, adopting green aluminium is not just an environmental imperative – it’s a strategic advantage. It enables businesses to meet regulatory requirements, enhance their brand reputation and attract environmentally conscious customers.

The current global aluminium market  

The global market for low-carbon or green aluminium is witnessing noteworthy developments as sustainability becomes a cornerstone of industrial growth. In Japan, Mitsui‘s strategic increase in its stake in Nippon Amazon Aluminium Co (NAAC) to 46% this year highlights the growing focus on aluminium produced with low-carbon energy sources. This move aligns with the escalating demand for green aluminium, as evidenced by Mitsui boosting its annual offtake from Albras in Brazil to 140,000 tonnes, recognizing the potential of this eco-friendly material. 

Albras, partly owned by NAAC, is a significant player due to its low carbon emissions, producing aluminium with a greenhouse gas emission rate of just 1.97 tonnes of CO2e per tonne. This achievement is powered by renewable energy sources, primarily from the Tucurui hydroelectric power plant and soon to be supplemented by the Boa Sorte solar power complex. 

In Europe, the market for low-carbon aluminium remains stable, with differentials for value-added products showing slight upward movements due to concluded transactions. However, the demand remains cautious, with some companies prioritizing cost over sustainability amidst economic uncertainties. This balancing act is critical as the market continues to adjust to the evolving landscape of green materials. 

The United States presents a different narrative, with the aluminium industry increasingly turning to scrap recycling to achieve its green objectives. This shift reflects a pragmatic approach in the absence of abundant renewable-powered electricity for primary production. While the spot market for low-carbon aluminium remains quiet, there is a growing interest from auto manufacturers who are beginning to inquire about long-term contracts, hinting at a future premium for such materials. 

Companies like Companhia Brasileira de Alumínio (CBA) are pivotal in this transition, investing in modernizing production processes to reduce carbon emissions, such as introducing technology for the disposal of dry residue. These efforts not only enhance operational efficiency but also prepare the company for a future where green aluminium is in higher demand. 
 
Brazil is a leading proponent of low-carbon aluminium production, as its industry already has carbon-emissions levels that are significantly below the global average. It also plans further emission cuts by increasing the use of renewable energy and recycling. 

As the market dynamics continue to evolve, the role of low-carbon aluminium differentials and premiums becomes increasingly significant. Although some sectors remain hesitant to pay a premium for these eco-friendly products, the gradual shift in consumer and industrial preferences towards sustainability suggests that the market is poised for growth. With only 25% of global aluminium production currently classified as green, there is substantial room for expansion, positioning companies that prioritize low-carbon solutions at the forefront of the industry’s future.
