Buzzi Unicem USA recently announced that the US Environmental Protection Agency (EPA) and the US Department of Energy (DOE) have awarded four of its manufacturing plants the ENERGY STAR® for their superior energy performance. The plants in Cape Girardeau and Selma (Missouri), Maryneal (Texas) and Chattanooga (Tennessee) received the honour.

During the last year, the plants used EPA's cement plant energy performance indicator (EPI). The  rating tool is an external yardstick that enables plants to assess how efficiently they use energy, relative to similar plants nationwide. Based on a rating systems scale of 1-100, plants receiving an EPI score of 75 or higher are eligible to earn ENERGY STAR recognition. In addition, the plant must have a three-year history of complying with several other environmental regulations.
