A Sustainable Use for Dried Biosolids
Lehigh Cement Company has conducted preliminary and in depth testing of Class A dried biosolids (DBS) as a fuel replacement in our cement kiln at Union Bridge, Maryland. Lehigh’s parent company, Heidelberg Cement, has been using DBS in European cement kilns for several years. These programs have proved the safety and environmental soundness of this concept. Lehigh’s ongoing development of these programs in North America will provide long term, sustainable solutions for DBS disposition.
