Composting is one of the options for treatment of solid waste. In the composting process, the organic matter breaks down under bacterial action resulting in the formation of humus like material called compost. Biodegradable solid waste can be composted either in compost pit or in a vermicompost pit.

  1. Composting (Manure Pit):
  • It is carried out in a simple manure pit or garbage pit (lined or unlined).
  • The average time it takes to complete the pit composting process is 3-6months.
  • It is a compact and tidy way to help organic waste to decompose and enrich the soil. A compost pit is also called trench composting.
  1. Vermicomposting: It involves the use of earthworms for composting organic solid waste. It is a resourceful way to recycle your food waste into compost. It takes about 2-3 months.
  2. Waste Converter Machines: By using waste converter machines, the composting process can be done in very less time. The semi-Automatic waste composting machine converts any kind of organic waste into compost within 12-15 days and an Automatic waste converter machine takes only 1-3 days in the composting process.

 

Hence, it is clear from the given points that the average duration of pit composting is around 3 to 6 months.
