Abstract: A method for recovering solid waste from a non-hazardous, non-septic liquid waste stream which includes the steps of: powering a drying gas heating mechanism, such as a furnace, using aerobically generated biogas as a power source for the liquid drying mechanism; passing at least a portion of the liquid waste stream through a mixer, such as an inline static mixer, prior to drying the at least portion of the liquid waste stream; substantially atomizing the waste stream output from the mixer; drying the atomized waste stream using a liquid drying mechanism, such as a spray dryer; and passing waste particulate, produced by the step of drying, through a particulate collector to produce solid waste particulate. Preferably, the process includes tapping the aerobically generated biogas from a landfill.
