Blockchain technology revolutionizing the aluminium industry for responsible sourcing and social impact

Blockchain technology is a cutting-edge database mechanism that enables transparent information sharing among participants within a business network. It operates by storing data in interconnected blocks, forming a chain-like structure. In the mining sector, blockchain technology enhances supply chains' transparency, reliability, and scalability, enabling companies to monitor the flow of metals and minerals effectively. It facilitates the tracking of critical information, including carbon emissions, water consumption, human rights issues, and financial transactions, ensuring a more transparent and accountable mining industry.

Now with a growing emphasis on ethical and transparent mining practices, the mining sector seeks to amplify its commitment to responsible resource extraction. The inherent transparency developed by blockchain technology is transforming the mining industry, empowering companies to efficiently track, record, and certify mineral origins and life-cycle information. From tracing emissions at the mine to validating the final product, blockchain's capabilities have proven invaluable.

Historically, the import and export process of minerals relied on cumbersome paperwork. However, with blockchain, secure exchanges of critical trade documents, like certificates of origin and bills of landing, are facilitated through smart contracts. This streamlined approach enhances efficiency and trust while promoting sustainable and responsible practices within the mineral supply chain.

While driving the growing need for environmental sustainability, the aluminium industry has proactively embraced innovation, introducing cutting-edge technologies to enhance the eco-friendliness of its operations. Additionally, the industry has implemented rigorous standards to gauge the impact of these advancements on the environment effectively.

In recent times, we have seen a few primary aluminium producers have launched sustainable aluminium brands, showcasing a commendably low carbon footprint of approximately 4 tonnes of direct and indirect CO2eq emissions per tonne of aluminium manufactured. Nonetheless, ensuring the credibility of these eco-friendly claims requires robust monitoring and verification, commonly accomplished through third-party auditing processes.

The Norwegian aluminium leader Hydro and the global mining and metal giant Rio Tinto have implemented cutting-edge blockchain-based systems to enhance and validate data collection processes for their sustainable aluminium products. This strategic integration of advanced technologies empowers consumers to meet the increasing demand for heightened transparency regarding the origins and production methods of the items they procure.

The aluminium industry can greatly benefit from a blockchain-enabled system, as it has the potential to establish clear provenance and verify the accuracy of responsible production claims. In 2021, the luxury auto manufacturer BMW Group announced a supply partnership deal with Rio Tinto's sustainability labelled for aluminium using blockchain technology 'START' to the multinational automakers' facility in Spartanburg, South Carolina, from 2024. BMW is considering achieving a 70 per cent reduction in CO₂ emissions by sourcing aluminium from Rio Tinto.
