Ans :- Methods of Waste Disposal

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.

Landfilling

A low-lying open area out of the city where garbage is collected and dumped is known as a landfill. The garbage is loaded into the truck and dumped in the landfill. When that area is fully covered with the garbage, it is covered with layers of soil. Now it can be converted into a park or a playground.

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 calledIncinerator. This reduces large amounts of garbage into a small amount of ash which can be disposed of in the landfill site.
