MCQs on Solid Waste Management

Solid-waste management is a process of collecting, disposing, and treating solid material that is discarded because it has served its purpose or is no longer useful. An improper municipal solid waste disposal can create unsanitary conditions. In turn, these conditions can lead to environmental pollution and to outbreaks of vector-borne disease -which are the diseases spread by insects and rodents. Solid-waste management tasks present complex technical challenges. Also, they pose a wide range of administrative, social, and economic problems that must be managed and solved.

Solid waste management also offers solutions for recycling items that do not belong to trash or garbage. As long as the people have been living in residential areas and settlements, solid or garbage waste has been an issue. Waste management is all about how solid waste can be converted and used as a valuable resource.

Solid waste management should be adopted by each and every household, including business owners across the world. Industrialization has induced a lot of good things and as well as bad things. One of the adverse effects of industrialization is solid waste creation.

There are various methods that are planned towards waste management, and on this common issue, some solid waste management micro-projects have also been introduced by many of the experts. Vegetative segregation is also one among them where it results from partitioning of cytoplasmic organelles and from random replication.

Let Us Get Some Understanding by Taking Some MCQs on Solid Waste Management.

1. The integrated waste management plan

2. Recycling of waste management plan

3. Reducing the waste management plan

4. Use of waste management plan

Answer: (a)

Explanation

Solid waste disposal should be part of an integrated waste management plan. This integrated solid waste management method is a plan of collection, processing, resource recovery, and final disposal of solid waste.

2. The ‘Municipal Solid Waste’ Is the Term Used to Describe Which Kind of Solid Waste?

1. Hazardous

2. Toxic

3. Non-hazardous

4. Non-toxic

Answer: (c)

Explanation

Generally, the ‘Municipal Solid Waste’ term is used to describe most of the non-hazardous solid waste from a Village, Town, or City that requires a daily collection and transport to a disposal site or to processing.

3. Identify the Following Ones Which Can Be Recycled Many Times?

1. Plastic

2. Wood

3. Organic materials

4. Aluminum

Answer: (d)

Explanation

Recycling means reusing some of the components of the waste that have some economic value. Aluminum can be recycled as many times as we want. The mining of new aluminum is quite expensive, and hence recycling of aluminum plays a vital role in the aluminum industry.

4. Why Do Plastics Fall Under a Difficult Material to Recycle?

1. Because it is a very hard material

2. Because plastic is very adhesive in its nature

3. Because of different types of polymer resins

4. Because of the different sizes of plastic

Answer: c

Explanation

Plastic is a very difficult material to recycle due to various or mixed types of polymer resins in their production. Since each plastic type has a distinct chemical composition, different plastic materials cannot be recycled together.

5. How Does an Organic Material Decompose in the Buried Solid Waste?

1. By the action of microorganisms

2. By the action of oxidation

3. By the soil particles

4. By the flow of water

Answer: (a)

Explanation

The organic material will decompose in the buried solid waste due to the action of microorganisms. At first, the waste aerobically decomposes until the oxygen present in the freshly placed fill is used up by the aerobic microorganisms.

6. What is Called for the Method of Burning Municipal Solid Waste in a Properly Designed Furnace Under Operating Conditions and Suitable Temperature?

1. Landfill

2. Recycling

3. Vermicomposting

4. Incineration

Answer: (d)

Explanation

Incineration is a chemical process in which the flammable fraction of garbage is mixed with oxygen and discharged into the environment as carbon dioxide and water. For incineration, the right temperature and operational conditions are required.

7. Why is Recycled Paper Banned for Usage in Food Containers?

1. Because paper is used only one time

2. Because it creates contamination

3. Because the paper is very thick and it cannot cover the food containers

4. Because it creates a lot of spaces

Answer: (b)

Explanation

To avoid contamination, recycled paper is not allowed to be used in food containers. Raw paper pulp is frequently less expensive to carry than scrap paper.

8. Identify the Wastes That Are Known as the Municipal Solid Waste (MSW) from the Following?

1. Wood pieces

2. Plastic cans

3. Food wastes

4. All of the above

Answer:(d)

Explanation

Trash or rubbish is made up of ordinary goods such as product packaging, grass clippings, furniture, clothing, bottles, food scraps, newspapers, appliances, paint, and batteries that we use and then discard. This is found in our homes, schools, hospitals, and workplaces.

9. The Wastes Burning Is Not an Acceptable Practice of Solid Waste Management Because ____?

1. It requires a lot of space

2. It requires modern technologies

3. It causes several environmental issues

4. It is very costly

Answer: (c)

Explanation

Burning rubbish is not an acceptable practice because it produces a lot of pollution and is hazardous to both the environment and creatures from an environmental and health standpoint.

10. Which of the Following Ones Is the Simplest and Most Common Method Used in the Cities to Dump the Wastes That Are Collected?

1. River

2. Ocean

3. Landfill

4. None of the above

Answer: (c)

Explanation

The most widely utilized form of trash disposal today is to dump everyday waste/garbage in landfills. This garbage disposal method relies on burying the material in the ground. In developing countries, landfills are common.

1. Methane

2. Nitrogen

3. Hydrogen

4. All of the above

Answer: (a)

Explanation

Landfill gas is a mix of methane and carbon dioxide, with a few other trace elements thrown in for good measure. It is formed naturally as organic matter decomposes in landfills.

12. Identify the Correct One from the Given List About Wastes?

1. There is no real waste in nature

2. The apparent wastes collected from one process becomes the input to another

3. All processes of consumption and production produce waste

4. All of the above
