Energy and Emissions Indicators

Energy consumption and indirect greenhouse gas emissions decreased across our operations in 2016. However, direct greenhouse gas emissions increased as a direct result of changes to our estimation and calculation methodology for greenhouse gas emissions for our largest facility, the Big Sandy plant in Catlettsburg, KY. Our methodology was revised based on site specific data obtained during the Title V permit renewal process, which includes a safety factor to account for potential fluctuations that may occur from variations in processing conditions. When energy data is normalized to activated and reactivated carbon production, since 2013, we have reduced our energy consumption by more than 9%.

Our most notable achievement in regards to our air emissions is our continued decrease in particulate emissions, which is a result of our continuous improvements in our dust handling systems and efforts to improve our carbon fines capture at the facilities. However, our reported NOx emissions have significantly increased as a direct result of revising the NOx emissions factors for our largest facility, the Big Sandy plant in Catlettsburg, KY. The NOx emissions factors were revised based on conservative assumptions necessary to estimate the worst case potential emissions from all products produced at the facility during the Title V permit renewal process.
