TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The sorting is performed by the waste matter generator. The evaporator is a ventilation system and/or a heating system. The ventilation system is a negative ventilation system and/or a positive ventilation system.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method-II further comprises: weighing the compostable organic waste matter concurrently to the collecting; weighing the compostable organic waste matter concurrently to the delivering; sorting the compostable organic waste matter from a noncompostable waste matter; providing training to an employee of the waste matter generator for sorting of the compostable organic waste matter from the non-compostable waste matter; providing an equipment for sorting of compostable organic waste matter from the non-compostable waste matter; and preparing composting bed in a composting compartment at the composting site prior to delivery of the compostable organic waste matter to the composting site. The method-II further comprises composting the compostable organic waste matter delivered at the composting site by the step (a) and (b) as above per se. In the method, when additional compostable organic waste matter and structuring agent is added in the composting mixture of step (a), where the ratio of the compostable organic waste matter to the structuring agent is 3:1-6:1. The step of preparing comprises mixing and distributing the composting mixture in the composting compartment to prepare the composting bed. The method-II further comprises: providing training to an employee of the composting site for performing a method of composting; visiting the waste matter generator for controlling the quality of the compostable organic waste matter; visiting the composting site for controlling the quality of the composting mixture; and providing technical support for performing a method of composting. At least one injector reinjects the leachate into the composting mixture. The leachate is uniformly reinjected into the composting mixture. The leachate is reinjected when the composting mixture has reached a temperature of 60-72 degrees C. The leachate is reinjected when the composting mixture has reached a density of 650-750 g/l. The mixing additional compostable organic waste matter of step (b) is performed once a week. The organic waste matter is delivered directly into a composting compartment at the composting site. Preferred Components: The structuring agent comprises sawdust, straw, peat, grass, jute, cardboard, corn cob granules, bark chips, woodchips, wood particles and/or manure. The leachate retaining base is made from concrete. The leachate retaining base is made from a plastic polymer. The initial ratio of the volume of organic waste matter to the volume of structuring agent is 1.5:1-3:1 or 2:1.5-3:1.5. The compostable organic waste matter in step (a) is 57% of the total initial volume of the composting mixture. The structuring agent in step (a) is 43% of the total initial volume of the composting mixture. ACTIVITY - Fertilizer.    MECHANISM OF ACTION - None given.
