A waste processing system () evaluates the waste processing requirements of a waste producing entity () and evaluates the waste processing capabilities of vendors (), and manages the waste processing of waste components produced by a waste producing entity () by selecting vendors () to service the waste producing entity ().

Waste processing system and method

A process for the stabilization of metal bearing waste is provided that is based upon the discovery that landfills have anaerobic environments. This process includes adjusting the pH of the waste and adding a sulfide containing reducing agent to the waste to achieve a reducing environment. In one embodiment, electric arc furnace dust is stabilized for landfill disposal. Also provided is a method for a determination of landfilled waste leachability. This method is performed under conditions that simulate the chemical characteristics of landfills. In one embodiment, stabilized metal bearing waste is deoxygenated and a simulated leachate is prepared under anaerobic conditions.

Hazardous waste stabilization methods, products and testing procedures

A method of processing electric arc furnace (EAF) dust which involves processing the EAF dust through a basic oxygen furnace (BOF). The method encompasses recovery of iron value from the EAF dust and the concentration of zinc into a material that has more flexible opportunities for its use as a feed to zinc manufacturing processes. The iron and zinc values in the EAF dust can be added to existing iron oxide recovery processes. This allows the EAF dust to be used as a substitute iron feed for BOF's. The method of processing EAF dust and the components thereof results in the reduction of the burden for the regulatory tracking of EAF dust. In addition, the method of processing EAF dust provides economic savings which result from the reduction of processing fees and the recovery of the value of iron and zinc materials.

Management of electric arc furnace dust through a basic oxygen furnace

Methods and apparatus for processing electric arc furnace (&ldquo;EAF&rdquo;) dust through a basic oxygen furnace (BOF) to recover iron value from the EAF dust and concentrate zinc from the EAF dust into a material useful as a feed in zinc manufacturing processes. The method results in the reduction of the burden for the regulatory tracking of EAF dust. In addition, the method provides economic savings which result from the reduction of processing fees and the recovery of the value of iron and zinc materials. The apparatus involves the use of existing equipment that is used to recover iron value from other materials generated at steel making facilities, or the installation of new equipment for the purpose of iron reuse.
