Red mud-based concrete cuts carbon footprint by up to 79.8% in Trinity College Dublin study

Researchers at Trinity College Dublin are testing a new type of concrete made using red mud, a residue from alumina refining. The project, supported by Enterprise Ireland and carried out with Gannon Eco and McGrath Quarries, has progressed from laboratory research to trials using industrial batching equipment. The university reported on 22 October that the geopolymer concrete formulations reduced the carbon footprint by 67.8–79.8 per cent against a CEM II-A/L cement reference. The comparison included raw material supply, transport and manufacturing. To know the futuristic market and value proposition of red mud, explore the report " A Comprehensive Analysis of Bauxite Residue (Red Mud): Sustainability, Resource Recovery and Strategic Recommendations " Laboratory tests also found that the...

Alumina steady-to-soft as spot tightens, deepening losses fail to spur cuts

Domestic spot alumina prices edged down slightly last week amid flat trading activity. Recent alumina price movements were mainly attributed to earlier concentrated restocking by downstream buyers, which has led to accumulating inventories at rail stations and smelters. Coupled with supply-side maintenance-driven output cuts that are still building, readily available spot volumes have tightened relatively. Only sporadic tender deals were heard recently, leaving prices in a temporary steady phase. On the bauxite front, domestic ore prices saw limited movement last week. Supply-side bottlenecks are unlikely to ease in the near term, with mines prioritising captive supply, leaving little excess spot material available. For imported ore, freight rates rebounded slightly and consecutively last...

AL Circle Analysis: Guinea’s 150Mt bauxite cap, China’s import swings, US tariffs draw aluminium Q4’26

The global aluminium supply chain is facing a series of changes that extend from bauxite mines and alumina refineries to smelters, regional premiums and finished-metal trade. In 2026, the market’s direction is being shaped not only by production volumes but also by freight costs, export restrictions, shifting Chinese demand and tariffs. Developments across Guinea, Australia, China, Europe and North America point to a market where access to supply is increasingly as important as the availability of raw materials. Bauxite supply: Guinea’s cap meets a well-stocked China, but is it stable? Guinea remains central to the seaborne bauxite market, with its shipment connections to China demonstrating the importance of reliable logistics. A new sea-rail route has enabled a Guinea bauxite shipment...

Hydro and Wave Aluminium sign a new contract to recover valuable minerals from bauxite residue

A contract signed between Hydro Alunorte and Wave Aluminium to construct a plant in Brazil that will process bauxite residue (red mud) to recover commercially valuable materials is expected to be operational by 2024. The facility will be constructed in Hydro Alunorte alumina refinery in Pará, Brazil. The proposed red mud processing facility will initially be able to treat 50,000 tonnes of bauxite residue annually using a novel mix of disruptive technologies. The new method will transform bauxite refuse into a resource and has demonstrated success in laboratory tests. "The preliminary results are highly promising and indicate a revolutionary scenario for the global aluminium industry when converting residue into products," stated Gustavo Emina, CEO of Wave Aluminium. After the bauxite...

Alcoa to install steam run MVR module in its Australian alumina refinery saving excess energy usage

After a feasibility study approved its potential outcomes, USA-based aluminium giant Alcoa is about to set up a steam recycling technology or MVR module focused on reducing emissions. As early as 2021, Australian Renewable Energy Agency (ARENA) allotted $11.3 million to run a feasibility study scrutinising the technical and commercial possibility of incorporating Mechanical Vapour Recompression (MVR) powered by renewable energy in Australian alumina refining processes. As the study has yielded positive results, Alcoa is on its way to purifying the next stage of its refinery for the future project by mounting a 4 MW MVR module at the Wagerup alumina refinery located in Western Australia. Alumina is extracted from bauxite which is then thrown into a series of technological processes to...

WA water authority to slash Alcoa's water licence by a third due to unsustainable supply in the region

The largest state of Australia, West Australia's water authority, announced that they would curtail mining giant Alcoa's water licence by a third due to unsustainable water demands in the region. Simone McGurk, the WA Water Minister, claimed that a 23 per cent drop in rainfall had led to significant changes in licensed water in the Murray region in the state's southwest. In addition to cutting the region's access to future available water by 40 per cent, the updated allocations for the Murray groundwater area, located an hour south of Perth, are currently being reviewed to determine if further reductions are needed. However, it implies that groundwater and shallow aquifer water are only available in places like Pinjarra and Nambeelup. Jane O'Malley, the CEO of Peel-Harvey Catchment...

Iran to escalate alumina production with Chinese assistance

According to an official, Iran has begun researching the possibility of producing 500,000 tonnes of alumina annually from low-grade bauxite with Chinese assistance. On January 23, 2023, Turaj Zar'e, the Managing Director of Iran Alumni Company (IAC), said, "The initial phase of studies was done with the Chinese, and we are conducting the second phase of the studies." He claimed that once the goal is met, Iran will be self-sufficient in alumina. "80 per cent of Iran's demand for alumina is met with imports which cost the country $1 billion a year", the MD added. According to Zar'e, the country's bauxite resources could be of better quality; hence, they are unsuitable for alumina powder production. Iran's most remarkable bauxite deposit is located in the northeastern province of North...

Otium Capital invests €8 million in green industrial tech company IB2 to accelerate its development

The green industrial tech company IB2 founded by Yves Occello, has developed a green and innovative technology allowing alumina refineries to process and valuate low-grade bauxite ores. Many alumina refineries have so far chosen to import bauxite rather than utilize close-by local resources because the depletion of high-quality local resources constrains them. IB2 provides these refineries with a real alternative, making low-grade bauxite viable through its revolutionary and environment-friendly process. Thus, beyond the financial and strategic benefits generated by IB2 Technology, refineries will dramatically improve their carbon footprint and fully participate in the circular economy. Indeed, the IB2 technology not only reduces wastes but also evaluates them through producing a highly...

Rio Tinto claims Labor’s policy validates industry wide sustainability drives

Rio Tinto seemed quite pleased with the Albanese government’s fundamental emissions-reduction policy for supplying vital support to heavy industries since it was aware of the environmental impact that the high-carbon east-coastal alumina units were causing. Rio Tinto knows that its refineries and smelters are the most ginormous sources of greenhouse gases (GHG), and it is inevitable that from July 1, they will witness strict emission caps. This was made clear through a draft released by the Government on January 10, titled, ‘Safeguard Mechanism’. Somehow, Rio Tinto’s Australian chief executive, Kellie Parker, lauded the step by the Government and displayed her gratitude for the support it would lend to heavy energy-intensive industries. She claimed this was “at the heart of today’s...
