Aperam’s Timóteo completes coke-to-charcoal switch


Measures to reduce the carbon footprint of steelmaking can also help to reduce steelmaking costs, if the situation is right.The use of charcoal has its limitations, it can only be used in small blast furnaces for example. However, for Aperam in Brazil, which uses small-scale blast furnaces and has a charcoal producing subsidiary operating nearby its plant, changing its raw materials can reduce costs, provide a stream of carbon credits and improve its environmental credentials.

SBB 27 July Stainless, electrical steels and special alloys maker Aperam’s Brazilian unit Timóteo has finalized the conversion of its No 2 blast furnace fuel from coke to charcoal, Steel Business Briefing learns from the company.

The mill said last year it would invest R$175m (US$114m) to replace imported coke and metallurgical coal with domestically sourced charcoal in a move that will result in “a total replacement of this power matrix.”

SBB estimates the cost of charcoal is around one-third that of coke, with the use of the former allowing Aperam to earn carbon credits.
