Method of the present invention is more efficient and economical for the drying of waste materials to combustible fuel than conventional drying methods and apparatus. Preblended portions of the organic material are deposited sequentially into a fermentation zone of a chamber and hot exhaust gases generated by the fermentation process are passed through an air-to-air heat exchanger along with cooler ambient intake air which is in its turn heated and turned back on the waste material in the second drying stage. |
