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

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...

Africa & Asia’s (ex-China) robust daily average alumina production in Feb’24 suggests its growth trajectory

According to the International Aluminium Institute survey, alumina production in Africa & Asia (ex-China) during February 2024 recorded a significant annual growth of 13.8 per cent but a month-on-month fall of 3.06 per cent. As per the data, Africa & Asia’s (ex-China) alumina production in February 2024 was 1.171 million tonnes versus 1.029 million tonnes a year ago, indicating that alumina production in Africa & Asia (ex-China) is on a steady growth path. The output declined month-on-month from 1.208 million tonnes mainly because of fewer calendar days in February. Africa & Asia’s (ex-China) daily average alumina output in February 2024 further underpins the above statement as the volume stood at 40,400 tonnes, up by 3.59 per cent from 39,000 tonnes in January 2024.
