MMK To Invest RUR 3bn in Green Project

UrBC, Magnitogorsk, May 21, 2018. MMK Group is starting on a large-scale environmental project: the plant intends to switch to a new format of cooling off its blast-furnace slag that requires no water. The project’s cost is estimated at RUR 3bn, the company press service reports.

The Waterless Cooling-Off Project is being worked on by MMK Group’s member enterprise OOO Shlakservis. The goal is to reduce as much as possible the harmful impact the plant’s slag-processing production facilities have on the environment. Once everything has been completed, the overall amount of air emissions will go drastically down, while the macadam that is the end product of the plant’s blast-furnace slag processing efforts will be much more durable.

The decision to go through with the project was taken at MMK’s Strategic Development Council. The plant has to rely on the use of water to cool off its blast-furnace slag at the moment. Once the hot slag enters into a reaction with water particles, hydrogen disulfide with a very characteristic smell (keenly disturbing even in small, within-the-limit concentrations) gets emitted.

According to OOO Shlakservis’s Tech Group’s Senior Manager Danil Evseyev, the new technology allows for cooling off slag with air. This means almost no harmful substances will get emitted, which will improve the overall environmental situation both on the production site and in the city of Magnitogorsk considerably.
