Which of the following is NOT a common waste disposal method?

  1. Landfilling

  2. Incineration

  3. Recycling

  4. Composting


Correct Option: B
Explanation:

Incineration is not a common waste disposal method because it releases harmful pollutants into the atmosphere, contributing to air pollution.

What is the primary goal of waste management?

  1. To reduce waste generation

  2. To properly dispose of waste

  3. To recover valuable materials from waste

  4. All of the above


Correct Option: D
Explanation:

Waste management aims to reduce waste generation, properly dispose of waste, and recover valuable materials from waste, promoting sustainability and protecting the environment.

Which disposal method involves burying waste in the ground?

  1. Landfilling

  2. Incineration

  3. Recycling

  4. Composting


Correct Option: A
Explanation:

Landfilling is a disposal method where waste is buried in the ground in a controlled manner, isolating it from the environment.

What is the main advantage of recycling?

  1. Reduces the need for raw materials

  2. Conserves natural resources

  3. Reduces greenhouse gas emissions

  4. All of the above


Correct Option: D
Explanation:

Recycling offers multiple benefits, including reducing the need for raw materials, conserving natural resources, and reducing greenhouse gas emissions, contributing to a more sustainable waste management system.

Which disposal method involves burning waste at high temperatures?

  1. Landfilling

  2. Incineration

  3. Recycling

  4. Composting


Correct Option: B
Explanation:

Incineration is a disposal method where waste is burned at high temperatures, reducing its volume and converting it into ash and gases.

What is the primary purpose of composting?

  1. To convert organic waste into a nutrient-rich soil amendment

  2. To reduce the volume of waste

  3. To generate biogas

  4. All of the above


Correct Option: A
Explanation:

Composting is a process where organic waste is broken down by microorganisms into a nutrient-rich soil amendment, promoting soil health and reducing the need for chemical fertilizers.

Which disposal method involves separating and recovering valuable materials from waste?

  1. Landfilling

  2. Incineration

  3. Recycling

  4. Composting


Correct Option: C
Explanation:

Recycling is a disposal method where valuable materials are separated from waste and processed into new products, reducing the need for raw materials and conserving natural resources.

What is the main environmental concern associated with landfilling?

  1. Air pollution

  2. Water pollution

  3. Soil contamination

  4. All of the above


Correct Option: D
Explanation:

Landfilling can lead to air pollution from landfill gas emissions, water pollution from leachate contamination, and soil contamination from improper waste disposal practices.

Which disposal method is considered the most environmentally friendly?

  1. Landfilling

  2. Incineration

  3. Recycling

  4. Composting


Correct Option: D
Explanation:

Composting is generally considered the most environmentally friendly disposal method as it diverts organic waste from landfills, reduces greenhouse gas emissions, and creates a valuable soil amendment.

What is the term for the process of converting organic waste into biogas?

  1. Anaerobic digestion

  2. Aerobic digestion

  3. Pyrolysis

  4. Gasification


Correct Option: A
Explanation:

Anaerobic digestion is the process of converting organic waste into biogas, a renewable energy source, in the absence of oxygen.

Which disposal method involves converting waste into a synthetic gas?

  1. Landfilling

  2. Incineration

  3. Recycling

  4. Gasification


Correct Option: D
Explanation:

Gasification is a disposal method where waste is converted into a synthetic gas through a thermochemical process, which can be used as a fuel or to produce chemicals.

What is the main advantage of waste-to-energy technologies?

  1. They reduce the need for landfills

  2. They generate renewable energy

  3. They reduce greenhouse gas emissions

  4. All of the above


Correct Option: D
Explanation:

Waste-to-energy technologies offer multiple benefits, including reducing the need for landfills, generating renewable energy, and reducing greenhouse gas emissions, promoting a more sustainable waste management system.

Which disposal method involves breaking down organic waste using microorganisms in the presence of oxygen?

  1. Anaerobic digestion

  2. Aerobic digestion

  3. Pyrolysis

  4. Gasification


Correct Option: B
Explanation:

Aerobic digestion is a disposal method where organic waste is broken down using microorganisms in the presence of oxygen, resulting in the production of compost or biogas.

What is the term for the process of converting waste into a liquid fuel?

  1. Pyrolysis

  2. Gasification

  3. Hydrothermal liquefaction

  4. Anaerobic digestion


Correct Option: C
Explanation:

Hydrothermal liquefaction is a process where waste is converted into a liquid fuel through a thermochemical reaction in the presence of water at high temperatures and pressures.

Which disposal method involves breaking down organic waste using heat in the absence of oxygen?

  1. Anaerobic digestion

  2. Aerobic digestion

  3. Pyrolysis

  4. Gasification


Correct Option: C
Explanation:

Pyrolysis is a disposal method where organic waste is broken down using heat in the absence of oxygen, producing a variety of products including bio-oil, charcoal, and gases.
