TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Composition: The majority of food waste decomposed is greater than 55% of the food waste, where the majority of food waste decomposed is 97% of the food waste. The combination of microorganisms comprises at least one species of bacillus and at least one species of lactobacillus, where the combination of microorganisms comprises four species of microorganisms, where each of the four species of microorganisms has a DNA sequence comprising 1380, 1432, 1343, or 1389 bp (SEQ ID NO: 5-8), where the composition comprises at least 85% SEQ ID NO: 5, 12% SEQ ID NO: 6, 1.5% SEQ ID NO: 7, and 1.5% SEQ ID NO: 8. At least one of the strains of microorganisms is capable of decomposing long chain starches. The composition further comprises a filler material, where the filler material is a husk, wood chip, man-made filler or their combinations, where the wood chip is a cedar wood chip, where one of the microorganism species is a species of eumycetes.Preferred Device: The device further comprises a control panel attached to the processing container for controlling the speed of the stirring axis, temperature, and humidity inside the processing container, where the control panel further controls oxygen supply to the processing container. The stirrer arm is bladed, where the stirrer arm is U-shaped. The humidity in the processing container of the device is maintained at 65-75%. The temperature in the processing container is maintained at 20-35degreesC. The combination of microorganisms comprises at least one species of bacillus and at least one species of lactobacillus, where the effective combination of microorganisms comprises four species of microorganisms.Preferred Method: Decomposing greater than 55% of food waste material into water and carbon dioxide comprises adding an amount of a combination of at least two species of microorganisms chosen from bacillus, lactobacillus, burkholderia, yeast fungus, eumycetes and their combinations, and mixing the food waste material and the combination of microorganisms for a time to allow the combination of microorganisms to decompose a majority of the food waste into water and carbon dioxide. The method further comprises soaking filler material with the elective combination of microorganisms. One gram of the elective combination of microorganisms is mixed with 110 kilograms of food waste material. EXAMPLE - No suitable example given.
