Lehigh Cement Co. received approval from the NYDEC to now use alternative energy sources in addition to its current use of natural gas and coal. This approval modifies Lehigh's air emissions permit to allow them to burn "ragger tail" as fuel, which consists of 60% plastic and 40% cardboard fiber and is sold to recycling companies after use. Ragger tail is considered a low-carbon fuel and has been used for the construction industry in Europe and Canada. Lehigh hopes that this change will allow for cheaper fuel costs and less environmental impact.
