The timed opening of the fan and poppet valve allow for expelling of excess moisture within the compartment (105) while conserving heat and energy.
  • the tumbling process is closely related to the heating, the process is highly controlled to reduce power consumption and also allow maximum moisture removal.
  • the tumbling frequency is kept to optimum such that it is low enough to avoid lump formation and high enough to prevent burning in the mixture or lack of aeration.
  • the output of the composting unit 100 is stabilized organic matter which is smell-free and doesn't attract any pests but still needs to undergo a curing phase.
  • the odour produced while the composting happens may also be controlled using either odour controlling bacteria or odour masking aromas as a part of the inoculum or even in some cases by passing outbound air through a lime bath or char filter to extract any volatiles with unfavourable aromas.
  • FIG. 4 illustrates a flowchart showing the conversion of wet waste to manure in accordance with an embodiment of the present subject matter.
  • Wet waste is added in the pre-compost bin and bulking agent is mixed with the wet waste inside a pre-compost bin. Mixture of shedding waste and bulking agent obtained from the pre-composed when his then added to the composter, following which, said mixture remains in the composter for three days. After this step, semi-decomposed organic waste is obtained from the composter. The semi-decomposed waste so formed added to the dryer and after five days manure is obtained as the output.
