NOVELTY - Organic and inorganic wastes are rotary anaerobically digested to produce premium quality compost and recycled fuel, by using two digesters. The first digester decomposes the organic matter through the rapid increase in temperature outside the digester under anaerobic conditions. The second digester completes the process decomposition, while water vapor and moisture are removed through a fan extractor and the product is stabilized.    USE - For rotary anaerobic digestion of organic and inorganic waste to produce premium quality compost and recycled fuel.    ADVANTAGE - The invention has the following advantages: (1) it can process organic and non-organic wastes; (2) process takes place in closed rotating drums no emission or odors; (3) much shorter processing time (2-4 days); (4) one-technology - integrated waste treatment; (5) fully automatic process control; (6) less plant area required in comparison to other processes; (7) lower investment costs; (8) lower operating and maintenance costs; (9) two final products - premium quality compost or fuel (green coal); (10) no pathogens in the final product; (11) optional recycling of water into liquid fertilizer; (12) treats dewatered sewage sludge; (13) treats abattoir effluent; (14) flexible and easily expandable to meet increased demand (phased and modular construction; (15) plants designed to specific requirements (versatility); (16) high recycling rate; and (17) positive environmental impact.    DETAILED DESCRIPTION - Rotary anaerobic digestion of organic and inorganic wastes to produce premium quality compost and recycled fuel by using digesters (5) which accept waste of any description, such as agricultural, industrial, biochemical, biological, or municipal waste. Each digester has a system which hermetically seals the digester so that the disintegration of the waste commences and conditions of anaerobic thermophilic decomposition are created. These conditions develop in the digester which is of a cylindrical or other shape. The decomposition creates a thermophilic range for the development of anaerobic fermentation by self-oxidation. Because the preservation of the thermophilic range is necessary as an important component of the decomposition of the waste, the digester, whose capacity varies, is rotated by a motor so that the resulting change in the position of the waste maintains the thermophilic range. The critical point of the process is the development of increasing temperatures which results from the decomposition, with minimal temperature loss to the environment. Internally the digester bears a system of lifters with fins and separators fixed to the internal surface. The purpose of this system is to mix the waste so that the temperature develops to the desired critical point, as the development of the temperature has the result of maximizing the anaerobic decomposition and the breakdown of the waste into increasingly smaller pieces. The digester and mixer are independent but collaborating mechanisms driven by separate motors in a parallel or opposite direction of rotation at the speed of rotation depending on the needs. The efficient breakdown of the waste requires an increase in the friction within the mass of the material, which can be achieved by varying the position of the digester in relation to the horizontal. This is achieved by means of a mechanical, electrical or hydraulic system, which adjusts the inclination of the digester in the most suitable position according to the requirements at any given time. For the product to become homogeneous and stable it is required that the processed mass becomes free of excessive moisture. Thus after the first stage of the process is completed the material is conveyed to a second digester where an automatic process takes place according to parameters such the temperature of the mass or the humidity. These parameters are detected by sensors and the signals that are produced by the sensors result in corrections to various aspects of the process, such as the revolutions of the digester, mixer, or extraction fan (10) or the inclination of the digester, so that the removal of moisture is interrupted at the point where the bacterial breakdown has been completed and the material is homogenous and ready for utilization as compost or as green coal. At this point the process has produced recycled fuel, which can be used to produce electric, mechanical or thermal energy which can be used to power the central anaerobic digestion unit of any external energy sources such as liquid fuel or electricity from external sources. This allows the unit to be located in remote locations away from residential areas and the availability of external power, as the only external energy required will be the relatively small amount of energy to power the first cycle operation which will produce the first quantity of green coal which can be used to repeat the process.
