NOVELTY - Producing biodiesel, biofuel, methane and protein fodder from kitchen waste, involves separating the extract of kitchen waste to obtain coarse solid product and oil-water mixture, separating usable and unusable components from coarse solid, pulverizing the usable components, treating pulverized components to obtain fine solid and oil-water mixture, processing obtained oil by ester exchange to obtain biodiesel, processing and fermenting waste water using microbial strain to obtain protein fodder, then fermenting waste water using methane bacteria to obtain methane.    USE - The method is useful for preparing biodiesel, biofuel, methane and protein fodder.    ADVANTAGE - The method is inexpensive and completely recycles the nutritive material of the kitchen waste.    DETAILED DESCRIPTION - Producing biodiesel, biofuel, methane and protein fodder from kitchen waste by microbial fermentation, involves extracting kitchen waste, separating the extract to obtain coarse solid product and oil-water mixture, separating usable and unusable components from coarse solid, pulverizing the usable components, treating pulverized components using pressure filter to obtain fine solid particles and oil-water mixture, treating obtained oil-water mixture using oil-water separator to obtain oil and water containing organic materials, separating the oil from water, processing oil emulsification and ester-exchange to obtain biodiesel, liquefying separated waste water and fine solid particles in the presence of amylase and sterilizing the liquefied mixture, fermenting the sterilized mixture using saccharifying enzyme and Saccharomyces cerevisiae or Clostridium caetobutylicum and then distilling the fermented mixture using ethanol and collecting the supernatant from the distilled mixture, filtering the mixture under pressure to form residual solid and waste water, drying the filterate, pulverizing dried residual solid with bran to obtain protein fodder, fermenting waste water with fine solid particles, and collecting supernatant from the fermented mixture using methane bacteria to obtain methane.
