AIR QUALITY
COMMITTED TO REDUCING AIR EMISSIONS
AIR QUALITY IN OUR COMMUNITIES
BlueScope Steel remains committed to reducing air emissions and improving air quality in the communities in which we operate.
BlueScope Steel has installed control mechanisms to reduce emissions at a number of our facilities to minimise air emissions. These systems include:
- Emission collection
- Baghouses and filtering
- Chemical treatment
- Thermal oxidisation
- Emission recycling
- Dust suppression
The Company extensively monitors emissions at our operations, both on and off site, to maintain compliance with regulatory limits and to understand our impact on the community.
Many sites are required to report emission levels to regulators with some results being published on public websites.
Among the most noticeable emissions from our steelmaking plants are air pollutants, such as oxides of sulphur and nitrogen, dust, odours and greenhouse gases.
Monitoring results for fine particulate, oxides of nitrogen and sulphur dioxide are shown in the graphs. This year we have seen a significant reduction in the amount of sulphur dioxide from our Port Kembla Steelworks. This is the result of a major project to install a gypsum plant which removes sulphur from the waste gases at the Sinter Plant. The reported increase in fine particulate emissions was primarily due to replacing emission estimates with actual test results.
