Global mining giant Rio Tinto has taken a significant step toward expanding its presence in the sustainable metals sector by signing a memorandum of understanding (MOU) with India-based AMG Metals & Materials (AMG M&M). The collaboration will focus on evaluating the feasibility of a large-scale, low-carbon aluminium and alumina production facility in India powered by renewable energy sources. The proposed development, still in the assessment phase, could result in a facility capable of producing up to 1 million tonnes per annum (mtpa) of primary aluminium and 2 mtpa of alumina. What sets this project apart is its reliance on green energy—wind, solar, and pumped hydro storage—rather than conventional fossil fuels, marking a milestone in India's push for sustainable industrial growth. In the initial phase, the two companies will study the viability of establishing a 500,000 tonnes per annum aluminium smelter at a strategically chosen site in India. Although Rio Tinto has not revealed the exact location or financial figures associated with the deal, the venture promises to be one of the largest of its kind in South Asia should it move forward.
Focus on Sustainability and Strategic Partnerships
The partnership brings together two sustainability-focused powerhouses. AMG M&M is a venture established by Anil Chalamalasetty and Mahesh Kolli, co-founders of Greenko Group, one of India’s most prominent clean energy companies. Greenko has already built a reputation for advancing renewable energy and integrated storage solutions in the Indian energy sector. Through this collaboration, AMG M&M will spearhead efforts to create a firmed renewable energy supply for the project using Greenko’s capabilities in wind, solar, and pumped hydro. Meanwhile, Rio Tinto will explore commercial options for a sustainable alumina solution that aligns with the company’s broader decarbonisation goals. Mahesh Kolli, Group President of AMG M&M and Greenko, emphasized the transformative nature of the initiative. “This MOU could deliver much needed low-carbon metal at scale to propel decarbonisation initiatives in global supply chains across auto, construction, consumer packaging and many more segments,” he stated.
Global Context: Demand for Sustainable Aluminium Rises
The MOU comes at a time when demand for sustainable materials is surging worldwide. Aluminium, widely used in sectors such as automotive, construction, packaging, and consumer electronics, is considered a critical metal for the green transition. However, traditional aluminium production is highly energy-intensive and carbon-heavy, especially when powered by coal-fired plants. Rio Tinto’s move is part of a broader strategy to reduce its carbon footprint while aligning with customers' growing sustainability expectations. The company is already involved in similar ventures, including the ELYSIS initiative in Canada, which seeks to produce aluminium without direct greenhouse gas emissions. India’s market offers a unique opportunity. With its growing industrial base, government focus on clean energy, and abundant solar and wind resources, the country is becoming a global hotspot for green industrial investments. The Rio Tinto-AMG M&M project taps directly into this potential, aiming to deliver large volumes of low-carbon aluminium for global and domestic consumption.
Although still in the early stages, the MOU signals intent from both Rio Tinto and AMG M&M to address one of the key challenges in aluminium manufacturing: carbon emissions. If the initial feasibility study proves successful, it could pave the way for one of the most ambitious green metal initiatives in the region. The implications of this project extend beyond just India. As global companies work to meet increasingly strict ESG (Environmental, Social, and Governance) standards, low-carbon materials like green aluminium could become central to supply chains worldwide. This partnership may well serve as a blueprint for future industrial collaborations that balance commercial objectives with environmental responsibilities. For now, stakeholders and industry watchers will be observing closely as Rio Tinto and AMG M&M begin feasibility assessments, navigate regulatory approvals, and develop plans for what could become a cornerstone of green manufacturing in the Asia-Pacific region.
