Engineered Aluminium’s Role In Decarbonization: From Lightweight Vehicles To Green Buildings


In the contemporary world, the global community is increasingly focused on the urgent need for decarbonization to combat climate change. Engineered Aluminium is a key player among various elements contributing to this transformative shift. This versatile metal has become synonymous with sustainability, finding its way into diverse industries that are moving towards eco-friendly practices. From revolutionizing transportation with lightweight vehicles to enhancing energy efficiency in green buildings, engineered Aluminium’s versatility and eco-friendly properties drive significant advancements towards a cleaner, greener future.

Why Aluminium is Considered a Green Metal

Aluminium is celebrated as a green metal due to its inherent properties, which promote sustainable material use and contribute to the circular economy. It consumes only ~5% of the energy compared to producing the same quantity of virgin Aluminium without losing its quality. By using this metal, industries reduce the need for new extraction and minimize mining-related environmental degradation, making it a highly sustainable choice. It is estimated that nearly 75% of all produced Aluminium is still in use today. Moreover, Aluminium’s durability and corrosion resistance ensure a longer lifespan for products, reducing the frequency of replacements and cutting down on overall waste generated. Furthermore, the lightweight nature of Aluminium makes it ideal for decreasing the carbon footprint in product-weight-sensitive industries.

Engineered Aluminium’s Comprehensive Role in Decarbonization

In modern economies, industries such as transportation, construction, and manufacturing contribute significantly to carbon emissions due to energy-intensive production processes and the use of fossil fuels. As the contemporary supply chain becomes increasingly interconnected with multiple sectors, there is a growing need to ensure sustainability across the entire chain. Therefore, engineered Aluminium emerges as a critical player, offering a comprehensive solution to reduce carbon emissions across various industries. While Aluminium’s influence spans multiple sectors, the spotlight often falls on its contributions to lightweight vehicles and green construction.

Aluminium in the Automotive Sector: One of the primary domains where Aluminium plays a vital role in decarbonization is automotive manufacturing. The lightweight properties of Aluminium contribute to enhanced fuel efficiency and reduced emissions. Electric vehicles (EVs) also benefit massively from this integration, as the reduced weight leads to a higher battery range and lower braking distances. The average aluminium content within EVs is projected to increase by 9.5% to 310 kg within 2022 to 2026. Moreover, Aluminium is important in electromobility infrastructure, covering power cables and charging stations. Beyond lightweight vehicles, Aluminium is also used in the railway and aviation industries as a lightweight component and in the shipping industry as a non-corrosive element, with its contribution in the transport sector worldwide projected to reach 27% of all end-use aluminium applications by 2027. This further reduces carbon footprint, promoting sustainability across the entire transportation infrastructure.

Aluminium’s Contribution to Green Buildings: Although Aluminium is a dominant material in construction today, it wasn’t until the iconic Empire State Building in 1931 that a major structure incorporated aluminium components and fabricated parts. The metal’s lightweight, versatility and durability make it a preferred choice for various building components, including doors, windows, curtain walls, louvres, facades and roofing. Furthermore, with its remarkable thermal performance, aluminium aids in maintaining optimal indoor temperatures without the need for artificial heating or cooling systems and contributes to energy savings. Aluminium’s corrosion resistance property ensures longevity, promoting the durability and resilience of green structures. Aluminium’s contribution to the construction sector is forecasted to reach 24% of its total end-use applications by 2027. Notably, initiatives like LEED (Leadership in Energy and Environmental Design) provide a framework for environment-friendly and highly efficient green buildings to reinforce the significance of engineered Aluminium in sustainable infrastructure projects.

Advancements in Engineered Aluminium Alloys

Continuous improvements in engineered aluminium alloys have revolutionized various industries. These alloys are developed to possess superior strength, unmatched heat resistance, lightweight properties and top-notch corrosion resistance, making them indispensable in modern engineering applications. Whether for high-performance aircraft components, high-voltage transmission wiring, high-frequency radars, future-ready robotics, seawater desalination, interior structures or durable consumer electronics, these advancements have enabled the development of lighter, more efficient and long-lasting products. Looking ahead, ongoing research about what is achievable with aluminium alloys will promise even more significant breakthroughs in the years to come.

Wrapping Up

In conclusion, Aluminium stands as an essential element in the pursuit of decarbonization, influencing industries ranging from transportation to construction. The emerging adoption of Aluminium is shaping the future of industries, with this metal becoming increasingly integral to the evolving renewable energy technologies such as solar panels, wind power and hydroelectricity. As we navigate the challenges of climate change, the pivotal role of Aluminium prompts a call to action for continued research and innovation. By harnessing the full potential of this versatile metal, we can collectively pave the way for a greener and more sustainable world.
