The company (AZST) switched one of its six blast furnaces from natural gas to coke gas. Coke gas is a by-product from the Markhokhim coke making plant, which was merged with Azovstal last year. Concorde Capital: Although the usage of coke gas is economically fully justified, this technology is limited to companies located in close proximity to coke producers. We expect Alchevsk Iron & Steel (ALMK: BUY) to adopt this process by utilizing the excess coke gas produced by Alchevsk Coke (ALKZ: SELL) in the near future.
