A key aspect of steel industry environmental protection is to minimise emissions to the air. Emission sources are mapped and monitored. Process improvements can then be identified and implemented with the goal of reducing emissions.

Control mechanisms to reduce emissions can include:

  • baghouse/filtration systems
  • chemical treatment
  • thermal oxidisation
  • scrubber systems
  • dust suppression.

worldsteel leads working groups covering various aspects of air quality to facilitate improvements and the spread of best practice throughout the industry. 

worldsteel will release a position paper on air quality in the course of  2019.
