    Abstract: This invention encompasses a process for the utilization of dried powdered waste as a fuel, in particular, dried powdered aqueous waste. The object of the invention is to eliminate the use of conventional auxiliary fuel to aid in thermal oxidation of waste materials containing a high percentage of water in relation to solids, thus improving the total efficiency of the process.
