CEMEX Kosmos, a cement company located in Louisville, Kentucky, has recently issued a statement that it plans to introduce scrap plastic into stoking the kiln that fires its cement. The company already burns a number of materials which could be potential health concerns such as coal and petroleum coke. According to James Bruggers of the Courier-Journal:
...industrial pollution has been an issue in southwest Louisville for decades. The plant is near the coal-fired Mill Creek power plant, and residents have long complained about dust and soot from both.
