Composting of Wastes: –Organic matter constitutes 35% to 40% of the municipal solid waste generated in India. This waste can be recycled by the method of composting, one of the oldest forms of disposal. It is the natural process of decomposition of organic waste that yields manure or compost, which is very rich in nutrients.
Composting is a biological process in which micro-organisms, mainly fungi and bacteria convert degradable organic waste into humus like substance. It recycles the nutrients and returns them to the soil as nutrients. The process of composting ensures the waste that is produced in the kitchens is not carelessly thrown and left to rot. Apart from being clean, cheap and safe, composting can significantly reduce the amount of disposable garbage.
Some Benefits:- Compost allows the soil to retain more plant nutrients over a longer period.
III. It makes soil easier to cultivate.
VII. Vermi-composting has become very popular in the last few years. In this method, worms are added to the compost. These help to break the waste and added exerea of the worms makes the compost very rich in nutrients.
The composting process is carried out by three classes of microbes:
III. Thermophiles – high temperature microbes.
The composting period is governed by a number of factors including, temperature, moisture, oxygen, particle size, the carbon – to – nitrogen ratio and the degree of turning involved. Generally, effective management of these factors will accelerate the composting process.
