Question

Explain the types of waste based on its nature and degradation?

Answer 1

Hint:Waste is defined as unwanted and unusable materials and is regarded as a substance that is of no use. Waste that can be seen in our surroundings is known as garbage. Garbage can be considered as a solid waste because that includes wastes from our houses (domestic waste), wastes from schools, offices, etc (municipal wastes), and wastes from industries and factories (industrial wastes). Wastes are classified into solid waste and liquid waste.

Complete answer:
Solid wastes include solid portions of the discarded material such as vegetables, fruits, glass bottles, crockery, plastic containers, metals, and radioactive wastes. The solid wastes may be biodegradable or non-biodegradable.
Liquid waste includes effluents of industries, fertilizer and pesticide solutions from agricultural fields, urban runoff of untreated wastewater and garbage, mining wastes, etc. Liquid wastes may be non-biodegradable or biodegradable. Some important liquid waste management methods are sewage treatment and removal of ammonia.
Types of Waste
Waste is divided into two types, that are, Biodegradable wastes and Non-biodegradable waste. These two kinds of wastes are explained below:-
Biodegradable waste
The wastes which come from our home include food remains, garden waste, etc. Biodegradable waste is also known as moist waste. This can be composted to obtain manure. Biodegradable wastes decompose themselves over a period of time depending on the material.
Non-biodegradable waste
Non-biodegradable waste is known as dry waste, for example old newspapers, plastics, etc. Dry wastes can be recycled and can be reused. Non-biodegradable wastes do not decompose by themselves and hence are major pollutants.

Note:Biodegradable waste can be decomposed and converted into the organic matter with the help of different processes.
