Green Anode Plant Commissioned at BALCO

Fives Group has announced the successful production of the first “green anode” at the BALCO Green Anode Plant in Korba, India, marking a significant milestone in the expansion of Bharat Aluminium Company Limited’s (BALCO) aluminium smelting operations. This development is part of a wider strategy to modernise smelter infrastructure and incorporate more sustainable, high-performance process technologies.

Anodes are essential components in aluminium smelting: solid carbon blocks that conduct electricity in the electrolysis cells of the Hall–Héroult process. In this process, aluminium oxide dissolved in a molten electrolyte is reduced to metal at high current levels, with carbon anodes consumed as part of the electrochemical reaction.

Green Anode Plant Technology and Its Differentiation
The term “green anode” in this context refers to anodes produced in a modern Green Anode Plant (GAP) designed to deliver consistent quality at high throughput while meeting environmental and operational performance criteria. Unlike older prebake or Söderberg anode production methods that can emit higher levels of volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs), contemporary GAP technology integrates advanced mixing, forming, and baking systems to optimise anode quality and reduce emissions.

Fives’ GAP solutions distinguish themselves in the global market through process efficiency, scalability and emission control. The company has extensive industry experience and installed bases that serve major aluminium producers worldwide. Fives’ technologies enable high production rates (noted in industry references for capacities over 60 tonnes per hour in some facilities) and compliance with stringent environmental standards on emissions of dust, tars and PAHs.

Project Execution and Collaborative Delivery
BALCO selected Fives for a full turnkey supply of a GAP with a capacity of 42 tonnes per hour as part of the smelter expansion. The project encompassed detailed engineering, procurement, construction and commissioning activities, combining global process engineering expertise with local execution and site management. Fives Solios provided core process design and equipment, Fives India managed local procurement and site supervision, and KEC International executed civil works, structural fabrication and detailed engineering. This integrated delivery model reflects an ability to address complex industrial challenges in demanding environments.

The first green anode produced at BALCO signals the transition from installation and pre-commissioning to active production and further operational optimisation. It also serves as an initial validation of equipment performance and process reliability ahead of ramping up to full industrial output.

Relevance to Industry Decarbonisation and Competitiveness
While the green anode itself remains a carbon-based consumable within the Hall–Héroult process, improvements in plant design and emission management contribute to lower environmental impact compared to legacy methods. Modern GAP installations focus on efficient material usage, process controls, and emissions abatement to align with tightening regulatory requirements and corporate sustainability targets.

In the broader context of decarbonisation, the aluminium industry is exploring revolutionary technologies such as inert anodes, which aim to eliminate direct carbon emissions by producing oxygen instead of carbon dioxide at the anode. These technologies represent a long-term shift that could fundamentally change smelting emissions profiles, although they remain in development and demonstration phases globally.

Outlook and Operational Next Steps
With the first green anode successfully produced, the BALCO Green Anode Plant moves into a phase focused on stabilising production, improving reliability, and optimising performance. Continued technical support and process tuning will be critical to achieving consistent quality and throughput, ultimately contributing to the expanded smelter’s operational objectives and competitive positioning in a market increasingly oriented toward sustainable industrial practice.

In summary, this milestone at BALCO exemplifies how modern anode production technology integrates high-capacity, lower-emission processes into primary aluminium operations, differentiating contemporary GAP solutions from legacy approaches and supporting strategic goals for efficiency and environmental performance.
