The main task of ISD Kokszoló Kft. is to produce good-quality blast furnace coke to supply the two blast furnaces of ISD DUNAFERR Zrt. Two coking batteries and the coal preparation, coke sorting and chemical plants that serve them are the main units of the plant.
With a yearly production value of nearly HUF 60 billion and employing more than 600 people, the core philosophy of the company is to produce coke and chemical products of appropriate quality to meet the requirements of the domestic and foreign market - according to domestic and EU regulations - using environmentally friendly technology. Since 1995, it has been operating under an integrated quality and environmental management system certified by the internationally recognized Det Norske Veritas certification body, in accordance with the requirements of ISO 9001: 2015, ISO 14001: 2015, and ISO 50001: 2011.
Of the nearly 1.4 million tons of coal used every year, circa 1 million tons of coke, 500 million m³ cleaned coke oven gas and other chemical products extracted from coal are produced in the coke ovens. Two-thirds of the coke produced is used by the DUNAFERR blast furnaces, the surplus and the chemical products are purchased by European steel and chemical companies as raw materials.
