The present invention relates to a Method and system for completion of Ecological cycle of Biomass, applying Nature to Nature (N2N) theory, by biological treatment of any biodegradable waste or organic waste, including biodegradable part of MSW, to produce rich biological fertilizer as end product, methane and many useful byproducts using natural processes and natural/organic materials within a very short time span. Thus, whatever is taken from nature is returned back to the nature in natural time span called as N2N Theory. |

1. A method for biological treatment of biodegradable waste, the method comprising the steps of:
loading mixed solid waste on a conveyor belt; passing the conveyor belt containing the mixed solid waste through a magnet chamber for separating metal parts from the mixed solid waste; passing the conveyor belt containing mixed solid waste through at least one separator, wherein biodegradable waste is separated from recyclable inorganic waste of mixed solid waste; collecting the separated biodegradable waste in a first storage tank; passing the separated biodegradable waste from the first storage tank to a primary treatment tank; treating the biodegradable waste in the primary treatment tank, wherein the treating in the primary treatment tank comprises mixing the biodegradable waste with hot water having temperature ranging from 70° C. to 140° C. to kill pathogens and simultaneously rotating the mixture with a rotor, then allowing natural settling, and repeating this treatment step at least twice for separating supernatant that contains non-degradable material from the naturally settled material, to form prepared sludge; dehydrating and compacting the prepared sludge; grinding and chopping the prepared sludge in a second storage tank to increase the surface area thereof; storing the prepared sludge in a third storage tank at a temperature ranging from 30° C. to 60° C.; treating the prepared sludge in a Biological Treatment Plant-I, wherein the prepared sludge is treated with a fluid comprising microbes, under anaerobic conditions, temperature ranging from 35° C. to 40° C., and pH of about pH 5.5 to pH 6.5, to form a treated slurry; treating the treated slurry in a Biological Treatment Plant-II, wherein the treated slurry is treated with enzymes, under anaerobic conditions, temperature ranging from 35° C. to 40° C., and pH of about pH 7.1 to pH 8.2; and treating the treated slurry in a Biological Treatment Plant-III, wherein the treated slurry is treated with thermophilic bacteria under anaerobic conditions at temperature ranging from 35° C. to 40° C. |
