The Portland Cement Association (PCA), founded in 1916, is the premier policy, research, education and market intelligence organization serving America's cement manufacturers. The Association promotes safety, sustainability, and innovation in all aspects of construction, fosters continuous improvement in cement manufacturing and distribution, and generally promotes economic growth and sound infrastructure investment.  
The annual PCA Chairman's Safety Performance Awards recognize outstanding safety performance in the manufacturing of Portland cement. A total of 13 winners were selected from nearly 100 cement facilities across the US found to be the highest performers in safety in 2020. 
For the fourth time in a row, Buzzi Unicem's Chattanooga Plant in Tennessee was one of the plants honored with this award, having completed 226,961 man-hours of work in 2020 without any reportable accidents.
