Question

Shruti has come to her ancestral village after an interval of ten years. She could not notice any garbage dumps on the roadsides. Surprised, on reaching her residence, she asked her grandmother as to where the garbage dumps went?

Answer 1

Hint: Garbage is the waste material that is discarded by humans. Waste can be liquid or solid. Garbage is anything worthless to be thrown out. For example, a plate of rotting food. It is a waste material which cannot be reused in the same form. Management of garbage involves the activities and actions that are needed to manage waste from its inception to its final disposal.

Complete answer:
- Grandmother took Shruti to the backyard near the cattle shed. She showed her a large inverted drum from where a pipe was going to the house.
- She told Shruti that the whole cattle dug and the garbage was dumped into a tank below the drum.
- It produces two things biogas or gobar gas due to the presence of cattle dung and the second thing is manure.
- The gas is taken to the kitchen for cooking purposes. This makes the surrounding cleaner. The kitchen has also become smoke-free which would come from burning firewoods and dried dung cakes.
- The benefit and result of this process are that now a few people are suffering from infectious diseases.

Additional information:
- Garbage is of two types of organic waste and hazardous waste.
- Organic waste is the waste that is biodegradable which has come from either animals or plants. It can be broken into methane or simple organic molecules and carbon dioxide.
- Industrial waste is hazardous as it contains chemical waste, so it affects human health and causes infections.

Note: Management of waste is a significant element of environmental protection. Production of biogas has two benefits one is that it is used as a fuel and the second one is that waste is degraded. If waste is not decomposed properly, it can affect human health by causing various infectious diseases. Waste is the house to many bacteria and mosquitos. So, it is concluded that degradation and recycling of waste material are necessary to lead a healthy life.
