ABSTRACT:
A method for removing contaminating material from a combination material containing the contaminating material and a reusable material includes placing the combination material in an enclosed perforated container, placing the container in in a tank having a cleaning fluid with microorganisms therein capable of consuming at least a portion of the contaminating material, whereby the microorganisms will cause separation of the contaminating material from the reusable material and the cleaning fluid and will cause the contaminating material to rise to the top surface of the cleaning fluid, skimming off the risen contaminating material from the top surface of the fluid, leaving the container in the fluid until the contaminating material is separated from the reusable material, and removing the container from the tank with only the reusable material left therein, the contaminating material being substantially removed therefrom.
