ECA is produced by heating raw anthracite to extremely high temperatures, typically between 1800°C and 2200°C, in an electric arc furnace. The process of electro-calcination is functionally similar to the traditional gas-fired method and produces a largely indistinguishable product. However, it operates as a continuous process, offering inherent efficiency advantages over conventional gas furnaces.
Due to its superior purity and low electrical resistivity, ECA is a high-quality carbonaceous material used in critical applications such as the production of carbon electrode paste (Söderberg paste) and other high-end carbon products. It is also widely used in foundries as a carbon raiser/recarburiser to enhance the carbon content of the melt.
Our ECA and CEP units will be equipped with state-of-the-art operational and R&D facilities, benchmarked against leading global players. Beyond meeting the growing demand, these facilities will set new standards in quality and innovation for the foundry and ferro alloy industries. By serving as a reliable and valued supplier, we aim to actively contribute to the sustainable growth, self-reliance, and long-term development of both the industry and the nation in the years to come.

The project is currently under execution and is expected to be commissioned within the current financial year. In addition to the main manufacturing equipment, the company will also install appropriate air pollution control devices to capture and manage potential fugitive emissions.
