Abstract: A metal waste recovery process for recovering useful material from a quantity of waste material. The waste material is a composition including oil, metals and organic materials. The first step of the process is to deposit the waste material into a slurry tank and to add water to the waste material to produce a mixable slurry. The slurry is then high energy mixed to evenly distribute the waste material throughout the slurry. The useful metal is then recovered from the slurry using a magnetic separator. The remaining waste material is transferred into an anaerobic reactor where the remaining waste material reacts with anaerobic organisms provided by bacteria in a sludge seed. The anaerobic reaction between the anaerobic organism and the organic materials of the waste material produces recoverable inorganic gases that are removed from the waste material slurry. The recovered inorganic gases are transferred to a storage vessel and compressed.
