Answer 1

Explanation:

Introduction

Waste is defined as unwanted and unusable materials and is regarded as a substance which is of no use. Waste that we see in our surroundings is also known as garbage. Garbage is mainly considered as a solid waste that includes wastes from our houses (domestic waste), wastes from schools, offices, etc (municipal wastes) and wastes from industries and factories (industrial wastes).

Sources of Waste

Sources of waste can be broadly classified into four types: Industrial, Commercial, Domestic, and Agricultural.

Sources of Waste

Industrial Waste

These are the wastes created in factories and industries. Most industries dump their wastes in rivers and seas which cause a lot of pollution.

Example: plastic, glass, etc.

Commercial Waste

Commercial wastes are produced in schools, colleges, shops, and offices.

Example: plastic, paper, etc.

Domestic Waste

The different household wastes which are collected during household activities like cooking, cleaning, etc. are known as domestic wastes.

Example: leaves, vegetable peels, excreta, etc.

Agricultural Waste

Various wastes produced in the agricultural field are known as agricultural wastes.

Example: cattle waste, weed, husk, etc.

Types of Waste

Commonly waste is classified into two types: Biodegradable and Non-biodegradable waste. These two kinds of wastes are explained below:

Types of Waste

Biodegradable waste

These are the wastes that come from our kitchen and it includes 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

These are the wastes which include old newspapers, broken glass pieces, plastics, etc. Non-biodegradable waste is known as dry waste. Dry wastes can be recycled and can be reused. Non-biodegradable wastes do not decompose by themselves and hence are major pollutants.

Recycling of Waste

Recycling of waste product is very important as this process helps in processing waste or used products into useful or new products. Recycling helps in controlling air, water, and land pollution. It also uses less energy. There are a number of items that can be recycled like paper, plastic, glass, etc. Recycling helps in conserving natural resources and also helps in conserving energy. Recycling helps in protecting the environment as it helps in reducing air, water, and soil pollution.

Decomposition of Biodegradable Waste

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

Composting

This is the method in which waste can be decomposed and converted into organic matter by burying them in the compost pits. The wastes are composed by the action of bacteria and fungi.

Vermicomposting

This method involves decomposition of organic matter into fertile manure with the help of red worms. This manure is known as vermicompost.

Chemical waste

Chemical wastes are wastes that are made from harmful chemicals which are mostly produced in large factories. Chemical wastes may or may not be hazardous. A chemical waste which is hazardous can be solid, liquid or gaseous and will show hazardous characteristics like toxicity, corrosivity, ignitability, and reactivity.
