Explain the method through which we can deal with the garbage......
Answers
Answer:
Incineration
This method is mainly used to dispose of the medical waste. In this method, garbage is burnt at a high temperature in a special furnace called Incinerator. This reduces large amounts of garbage into a small amount of ash which can be disposed of in the landfill site.
Answer:
1. Composting and Vermicomposting
This method is useful for the disposal of biodegradable waste. The part of the garbage which can rot in nature to form harmless substances is called biodegradable (plants and animal waste). Different biodegradable waste can be dumped in a pit. Here, it can be allowed to decompose after which the garbage will convert into useful manure. This is known as composting.
The process of decomposition may take around 2 to 3 months. To make the process fast, red worms may be used for composting. This method is called vermicomposting. Vermicompost is the high-quality manure.
