Novolipetsk, NLMK's main
production site in Lipetsk, continues to hot test its new dedusting
systems and high-capacity new-generation filters at the hot metal
pouring section in BOF Shop No.2 â€“ one of major sources of graphite
emissions into the air. The new equipment will reduce the dust load of
waste gases by 7.5 times, bringing the dedusting rate up to 99%.
Nitrogen will be used to protect the hot metal flow to reduce dust
levels. With the 40% increase in the Shop's production capacity, this
project will not only prevent an increase in air emissions, it will also
reduce the cumulative dust discharge from those sources by 60%.
The environmental project capex as part of NLMK's Technical Upgrade
Programme amounted to approximately RUB550 million. Another section of
BOF production will be equipped with such dust collection and cleaning
systems in the future.
Since the launch of its Technical Upgrade Programme in 2000,
Novolipetsk has implemented over 280 projects aimed at reducing air
emissions, worth almost RUB17 billion. As a result, the Company's
environmental footprint has reduced by 22%, and specific emissions have
been cut by almost 50% to 22.7 kg/t. The total environmental capex is
approximately RUB22.5 billion.
