Q 3. Polyblend is mixed with ..A... to lay roads in ...B... Complete the given statement by choosing the appropriate option for A and B:-

1. A-bitumen; B-Bengaluru
2. A-carbon; B-Delhl
3. A-plastic; B-Kolkata
4. A-cement; B-Chennai

Answer - a, A- bitumen; B- Bengaluru

Explanation: Polyblend, a type of plastic, is mixed with bitumen to lay roads in Bengaluru. Bitumen is commonly used as a binding material in road construction, and combining it with plastic (Polyblend) can help enhance the durability and flexibility of the road surface. Bengaluru, the capital of Karnataka in India, is known for its extensive road network and innovative road construction techniques.

Q 4. Eventually, the only solution for the treatment of e-waste, provided it is carried out in an environment-friendly manner, is:

1. Incineration
2. Burying in landfill sites
3. Dumping in developing countries
4. Recycling

Answer - d, Recycling

Explanation: Recycling is the only environmentally friendly solution for the treatment of e-waste. It helps reduce the amount of waste sent to landfills and incinerators and reduces the carbon footprint of electronic devices through energy-efficient processes. Recycling can help close the loop on electronic waste and create a circular economy for our future.

Q 5. Why is plastic so difficult to recycle?

1. It's a rigid material.
2. Because plastic is inherently sticky,
3. Due to different types of polymer resins
4. Due to the different sizes of plastic

Answer - c, Due to different kinds of polymer resins

Explanation: Since plastics come in many varieties, recycling them can be challenging as they all have different chemical compositions and properties. Various polymer resins make up plastics, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and many others. Recycling each resin requires a different approach.

Q 6. Identify the Wastes That Are Known as Municipal Solid Waste (MSW) from the following?

1. piece of wood
2. plastic can
3. food waste
4. all of the above

Answer - d, all of the above

Explanation: All of the above! Municipal Solid Waste (MSW) includes all four items: pieces of wood, plastic can, food waste, and all other discards from homes or businesses that are commonly collected by municipalities.

Q 7. 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, by the action of microorganisms

Explanation: Organic matter decomposes in the buried solid waste through the action of several processes, including microorganisms, oxidation reactions, soil particles, and water flow. The first two processes are biological and involve different types of microorganisms that break down complex molecules into simpler substances, such as carbon dioxide, water, and nutrients.

Q 8. Which of the following gases is generated when the matter inside the sanitary landfill breaks down?

1. Methane
2. Nitrogen
3. Hydrogen
4. All of the above

Answer - a, Methane

Explanation: Methane is the gas that is generated when the matter inside the sanitary landfill breaks down. Methane is a powerful greenhouse gas and can contribute significantly to climate change if not managed properly. Luckily, Solid Waste Management has developed processes to capture and convert methane from landfills into clean energy.

Q 9. Municipal solid wastes are burned in a properly designed furnace under suitable temperatures and operating conditions. This process is called as

1. Landfill
2. Incineration
3. Recycling
4. Vermicomposting

Answer - b, Incineration

Explanation: An incineration process involves burning municipal solid wastes at a suitable temperature under these operating conditions in a properly designed furnace. The heat generated by incineration helps to reduce the volume of solid waste and converts it into ash, pollutants, and heat energy.

Q 10. Solid Waste Management has how many functional components?

1. Four
2. Five
3. Six
4. Three

Answer - c, Six

Explanation: Solid Waste Management can include up to six functional components: Collection and transport, Processing and treatment, Disposal, Monitoring and regulation, Education and outreach, and Research and development. With these six components, it is possible to reduce, reuse, and recycle solid waste in order to protect the environment and human health.

Q 11. Which integrated waste management is reduced on an individual level?

1. Burning
2. Disposal
3. Recycling
4. Source reduction

Answer - d, Source Reduction

Explanation: This is the process of reducing the amount of waste generated at its source, such as purchasing products with less packaging and reusing materials whenever possible. Source reduction can reduce environmental pollution and save natural resources for future generations.

Q 12. Which of the following statements is not true about plastic waste?

1. Can be used to make organic fertilizer
2. It lasts longer
3. The toxic smoke is produced during combustion
4. All of the above

Answer - a, Can be used to make organic fertilizer

Explanation: Plastic waste cannot be used to make compost. Composting is a natural process that involves the decomposition of organic materials into nutrient-rich soil called compost. However, plastics are not biodegradable and do not break down easily like organic materials. Instead, they persist in the environment for a long time, causing pollution and harm to ecosystems.

Q 13. Which is the least preferred strategy of Integrated Solid Waste Management according to their Environmental benefits?

1. Landfills
2. Composting
3. Waste to Energy
4. Recycling

Answer - a, Landfills

Explanation: The landfill is the least preferred strategy of Integrated Solid Waste Management according to its Environmental benefits. While landfills provide a safe way to store waste, they are not seen as a sustainable solution as they require a large amount of land and can produce methane emissions which adds to global warming.

Q 14. In solid waste management, waste utilization is achieved by

1. Recover, reclamation of reproduce
2. Reuse, Reclamation, and Recycling
3. Recover, Recycle, and Reproduce
4. Reuse, Reproduce, and Recycling

Answer - b, Reuse, Reclamation, and Recycling.

Explanation: In solid waste management, waste utilization is achieved by implementing strategies such as reusing, reclaiming, and recycling. These methods help reduce the amount of waste that ends up in landfills and promote a more sustainable approach to waste management.

1. Recovery, reclamation, and reproduction (Option 1) do not accurately reflect common waste management practices. Reproduction is not typically associated with waste utilization.
2. Reuse, reclamation, and recycling (Option 2) are commonly employed strategies. Reuse involves using a product or material multiple times before discarding it, reclaiming involves recovering valuable materials from waste for further use, and recycling involves processing waste materials into new products.
3. Recovery, recycling, and reproduction (Option 3) is similar to Option 1 but replaces "reproduce" with "recycling." While recovery and recycling are valid strategies, reproduction is not directly related to waste utilization.
4. Reuse, reproduce, and recycle (Option 4) includes "reproduce," which is not typically associated with waste management. The accurate term is "reclamation," which involves recovering valuable materials from waste.

Q 15. Sludge bulking can be controlled by

1. Chlorination
2. Coagulation
3. Aeration
4. Denitrification

Answer - a, Chlorination

Explanation: Sludge bulking: A bulky appearance can be attributed to filamentous micro-organisms (e.g. fungi ). Filamentous micro-organisms are observed due to low nutrients and high pH levels in sludge Low F/M ratio and sludge age.
