All the typical processes of the steel industry generate emissions to air. In fact today, there is an environment regulation, which set requirements to restrict emissions to air in the steel industry field.
Diffuse emissions are mainly associated with material handling, stockpiling and transport activities.
Fortunatly, the steel industry conducts extensive air emissions monitoring to follow up on permit requirements and identify opportunities for continuous improvement. Monitoring in a typical steel facility includes source monitoring of emissions to identify potential sources of dust, NOx, SO2, and haevy metals. Other types of monitoring include deposition monitoring and biomonitoring.
In addition, most steel plants have invested in air quality modelling and other established management activities such as targeted audits/inspections, video surveillance, environmental readiness and community hotlines.
These management practices are designed to determine the steel industry’s ambient air quality contribution, assist in identifying the sources of emissions and drive improvement.
