The coke making industry has seen the classification of several tar-based coke plant wastes as being toxic, hazardous or requiring special handling. Environmental regulatory agencies have placed increasingly stringent restrictions on the handling, storage and disposal of these waste products. As an example, tar decanter sludge (TDS) is classified as a “listed” hazardous waste that must be recycled at a coke plant in an approved manner or transported to an approved secure landfill. In addition, other tar sludges and similar waste materials are often considered troublesome for disposal because they also require special handling. The AKJ process is a patented process used to convert TDS and other coke plant wastes into a pumpable fuel that has multiple alternative uses within the facility. Other waste materials, for example, tar tank deposits, tank car deposits, terminal treatment sludge and coke plant waste pond material have been successfully processed into beneficial liquid fuels. AKJ Steel Industries is currently operating plants to recycle these types of materials in the United States.
