Composting and it's types

What is Composting?

• In short, converting food waste in to manure is composting. 
• Food waste is converted into manure naturally, however this takes quite some time. While composting, we create an environment for the conversion process to happen faster.

Types of Composting

Food waste gets converted to manure in a natural process. In composting, we are making this process faster by controlling the environment. We can classify the composting process based on the type of environment we create.

The conversion of the food to manure is done by invertebrates. Invertebrates are lesser evolved organisms. One way to classify the composting technique is based on the type of invertebrate organism that is doing the job.

1. Worm Composting
2. Bacterial Composting
1. Aerobic Composting
2. Anaerobic Composting

1. Worm Composting

• In worm composting, the composting is done by earth worms.
• This is very good option, as the worms improve the soil quality also.
• The moisture and temperature levels of the compost needs to be maintained for the worms to stay alive.

2. Bacterial Composting

• In bacterial composting, the composting is done by bacterial.
• Based on the type of bacterial that is composting we can further classify this as aerobic composting and anaerobic composting

2.1. Aerobic composting

• In aerobic composting, the aerobic bacteria (bacteria that need air for live) is doing the job.
• The method when done properly does not emit any smell.
• Very effective of fruit and vegetable waste and dairy waste in medium quantities.
• However this method can not handle meat wastes.

2.2. Anaerobic composting

• In anaerobic composting, the anaerobic bacteria (bacteria that can note live in the presence of air) is doing the job.
• Very effective of fruit and vegetable waste and dairy waste in medium quantities.
• The method can handle meat waste also.
• There is methane generated in this process, that could be a quite smelly once the composting is done.
• The compost generated in this method have to be buried in soil before being used in the plants
