We are reducing air pollution at our facilities worldwide. Implementation of controls and best practices at our facilities in Brazil, China and the United States demonstrate our ongoing commitment to operating world-class, environmentally-friendly facilities.
We have a long-standing commitment to emission reduction. From the development of low nitrogen oxide (NOX) tail gas burners, the implementation of particulate matter monitoring systems, and state-of-the-art controls for NOX and sulfur dioxide (SO2), we have continued to improve our environmental footprint.
Two of our newest environmental goals are to reduce NOX by 20% and SO2 by 40% by 2025 compared to our 2012 baseline. While we have seen a slight uptick in absolute NOX emissions, our absolute SO2 emissions have decreased since 2012. We have also reduced the intensity of both air emissions per metric ton of production by 10% and 15%, respectively.
We have successfully implemented selective catalytic reduction (SCR) for the control of NOX in the carbon black industry in China. These same technologies will be implemented at our carbon black operating facilities in the United States. Additionally, we have implemented particulate monitoring systems in our carbon black plants that gives us an "early warning" of increasing emissions from our operations to allow us to react and implement corrective measures before these emissions are visible.
Local Environmental Initiatives
Reducing air pollutants with emission controls
To address air pollution challenges in China, the Shanghai Environmental Protection Bureau set a new NOX emissions standard of 150 milligrams/cubic meter at the end of 2014.
Our Shanghai facility responded promptly with a project to implement selective catalytic reduction technology that was completed in September 2015, a month in advance of required compliance. Professional third-party emissions testing confirmed that the concentration of total flue gas NOX emission was below the new limit, demonstrating a removal efficiency of up to 95%. This project has achieved the highest NOX removal efficiency rates of any project within our organization to date.
