Emissions

We understand the impacts associated with greenhouse gas (GHG) emissions and other air pollutants, including linkages to climate change, public health concerns and threats to ecosystems.

Our Commitment

We also recognize that emission reductions are often a signal of improving overall operational efficiency at our manufacturing facilities. We therefore see our focus on emission reductions as a potential competitive advantage, and we look to partner with our customers and others who share our goal of reducing emissions impacts across the value chain. We monitor our emissions closely and work to minimize our respective impacts in support of maintaining compliance with our regulatory obligations and reducing our global environmental footprint.

Our Performance

chart-environment-greenhoue-gas

By the end of 2018, we had realized 50% of our 2025 GHG reduction target. This was achieved through efforts to capture waste heat and offset our purchase of electricity and by improving our process yields through technology, product selection and feedstock selection. Looking forward, additional process technology improvements are under development for deployment at one of our recently announced expansions in Asia, with the expectation that this technology could be deployed at other facilities. 

In 2018, we experienced our first full year of operations of our NOX emission reduction system at our facility in Pampa, Texas, USA. This system has continuously achieved a 90% reduction for what was previously our most intensive facility in terms of NOX  emissions. Furthermore, we successfully completed the NOX control system at our largest carbon black manufacturing facility, in Tianjin, China; these controls also achieved a 90% reduction of  NOX emissions. Through these efforts, we were able to exceed our global NOX emission reduction target well ahead of schedule. 

Our SO2 emissions were consistent with previous years, with slight variation based on fluctuations in our feedstock sulfur content and the products we produced. However, we continue to make progress on the implementation of our SO2 control system at our facility in Franklin, Louisiana, USA, and we have started the early engineering for the control system at our nearby Ville Platte facility. These systems are expected to be operational in 2021 and 2022, respectively.
