As of 2016, Holcim is completing a $300 million upgrade to its Ravena plant that includes a new dry-process [[cement kiln]] that will replace two 50-year-old wet-process kilns. The new kiln will use less coal and emit fewer pollutants, including a 66% reduction in mercury emissions, while increasing production capacity. It will also take less water from the Hudson River, getting most of its water from the nearby limestone quarry that feeds the plant.<ref>{{Cite web|url=http://www.timesunion.com/tuplus-business/article/New-less-polluting-cement-plant-rises-in-Ravena-6673902.php|title = New, less-polluting cement plant rises in Ravena|date = December 3, 2015}}</ref>
