NOVELTY - Producing solid fuel using organic waste, comprises (a) grinding organic waste containing sewage sludge and food waste, (b) dehydrating, (c) mixing fallen leaves, microbial agent, with red clay or volcanic rocks, (d) fermenting the mixtures, (e) producing fermented microorganisms, (f) producing primary mixture, (g) producing primary additive, (h) producing secondary mixture, (i) mixing peat moss, metal compound, organic solvent, sodium carbonate binder with sodium borate to produce secondary additive, (j) producing tertiary mixture, and (k) introducing tertiary mixture in fuel molding machine.    USE - The method is useful for producing solid fuel using organic waste (claimed).    ADVANTAGE - The method is economical.    DETAILED DESCRIPTION - Producing solid fuel using organic waste, comprises (a) screening foreign object and metal components present in organic waste containing 50-70 wt.% sewage sludge and 30-50 wt.% food waste, and grinding in size of less than or equal to 1 mm, (b) dehydrating the organic wastes in a dehydrator until moisture content of 50-60%, (c) mixing 70-85 wt.% fallen leaves, 5-10 wt.% microbial agent including Aspergillus oryzae, sulfur bacteria, Bacillus subtilis, Lactobacillus, Schizosaccharomyces and Actinomyces with 10-20 wt.% red clay or volcanic rocks in a mixing chamber, (d) fermenting the mixtures in a reservoir for 2-7 days, (e) pulverizing the fermented leaves in size of less than or equal to 1 mm using a mill to produce fermented microorganisms, (f) mixing 70-90 wt.% dehydrated organic waste with 10-30 wt.% fermented microorganisms to produce primary mixture with moisture content of 40-50%, (g) crushing cornstalks, bean, coconut, palm, sawdust and rice husk in size of less than or equal to 1 mm, and mixing to produce a primary additive, (h) mixing 70-90 wt.% primary mixture with 10-30 wt.% primary additive to produce secondary mixture with moisture content of 30-40%, (i) mixing 50-70 wt.% peat moss, 5-10 wt.% metal compounds of nitrate, chlorate, oxalate or carbonate, 5-10 wt.% organic solvents of methanol, ethanol, benzene or toluene and 3-7 wt.% sodium carbonate binder, with 3-7 wt.% sodium borate deodorant to produce secondary additive, (j) mixing 60-90 wt.% second mixture with 10-40 wt.% pulverized second additive to produce tertiary mixture with moisture content of 20-30%, and (k) introducing the tertiary mixture in a fuel molding machine to produce solid fuel.
