Explain different types of waste.
Answer:
Waste can be solid, liquid or gas but on the basis of ability to undergo decomposition, waste is classified into two types.
- Biodegradable Waste: Waste which can be decomposed by biological factors is called biodegradable waste, e.g. fruit peels, stale food, paper, etc. Biodegradable is generally environment-friendly. Biogas is produced on decomposition of biodegradable waste. This biogas can be utilized for many purposes like as domestic fuel, for power generation, etc. Non-
- biodegradable Waste: Waste which cannot be decomposed by biological factors is called non-biodegradable waste, e.g. aluminium can, polythene bag, etc. Non-biodegradable waste is generally harmful for environment. However, many non-biodegradable waste can be recycled to make useful products.
Question 18:
Write an essay on waste management.
Answer:
The practice of transportation and dumping of waste, recycling of useful material from waste, etc. are integral part of waste management. Different types of waste need different kinds of management practices. While gaseous waste goes up in air on its own, we need to make proper drainage system for handling liquid waste. For handling solid waste, we need a proper system of transportation and people. Even a small village produces a large amount of waste per day. Daily production of garbage could be in thousands of tons in mega cities.

For handling solid waste, we need a proper system of transportation and people. Even a small village produces a large amount of waste per day. Daily production of garbage could be in thousands of tons in mega cities.
Methods of Waste Management:
- Landfill: Waste is dumped at landfill site. When amount of waste attains a significant figure, it is covered with soil. After that, waste is allowed to decompose. Pipeline system is installed in landfill to channelize and utilize the methane gas which is produced during decomposition. This gas is utilized for power generation at many places. A landfill site is usually developed outside the city limits.
- Incineration: In this method, waste is burnt under controlled conditions so that production of polluting gases can be minimized. This method is ideal for places where land is in short supply. This method is also ideal for disposing off the medical waste.
- Recycling: Certain items from waste are segregated for recycling. Items like plastic, aluminium cans, metals, etc. are sent to recycling unit so that new items can be made from them. This not only helps in reducing the amount of waste but also in conservation of resources.
- Chemical Methods: Many wastes can be managed by using chemical methods.
Question 19:
Write an essay on sources of waste.

- Industry and Mining: Many harmful wastes are produced by industries, e.g. harmful chemicals, grease, etc. Mining activity also produces wastes like dust.
- Agriculture: Hay, dry leaves, husk, cowdung, etc. are examples of farm waste.
- Medical Waste: Hospitals produce many wastes like syringe, cotton, bandage, catheters, strips, etc. Some of the hospital waste may contain harmful germs.
