What is the primary goal of the circular economy approach in waste management?

  1. To minimize waste generation and maximize resource utilization.

  2. To increase the efficiency of waste collection and disposal.

  3. To promote the use of renewable energy sources in waste management.

  4. To reduce the environmental impact of waste disposal.


Correct Option: A
Explanation:

The circular economy approach aims to keep resources in use for as long as possible, extracting the maximum value from them while minimizing waste and pollution.

Which technology is gaining popularity for converting organic waste into renewable energy?

  1. Anaerobic digestion

  2. Incineration

  3. Landfilling

  4. Composting


Correct Option: A
Explanation:

Anaerobic digestion is a process that breaks down organic matter in the absence of oxygen, producing biogas (methane and carbon dioxide) and digestate (a nutrient-rich fertilizer).

What is the term used for the process of recovering valuable materials from electronic waste?

  1. E-waste recycling

  2. E-waste disposal

  3. E-waste incineration

  4. E-waste landfilling


Correct Option: A
Explanation:

E-waste recycling involves recovering valuable materials, such as metals, plastics, and precious metals, from electronic waste through various processes like dismantling, shredding, and smelting.

Which type of plastic is commonly used in single-use packaging and is difficult to recycle?

  1. Polyethylene terephthalate (PET)

  2. High-density polyethylene (HDPE)

  3. Low-density polyethylene (LDPE)

  4. Polypropylene (PP)


Correct Option: C
Explanation:

LDPE is widely used in single-use packaging due to its flexibility and low cost, but it is challenging to recycle due to its low melting point and contamination issues.

What is the term used for the process of converting waste plastics into fuel or other useful products?

  1. Plastic pyrolysis

  2. Plastic incineration

  3. Plastic landfilling

  4. Plastic composting


Correct Option: A
Explanation:

Plastic pyrolysis involves heating waste plastics in the absence of oxygen to break them down into smaller molecules, producing fuel, chemicals, and other valuable products.

Which technology is used to capture and store carbon dioxide from industrial processes and power plants?

  1. Carbon capture and storage (CCS)

  2. Carbon capture and utilization (CCU)

  3. Carbon dioxide removal (CDR)

  4. Carbon sequestration


Correct Option: A
Explanation:

CCS involves capturing carbon dioxide emissions from industrial sources and storing them underground or in geological formations to prevent their release into the atmosphere.

What is the term used for the process of converting waste biomass into liquid fuels?

  1. Biomass gasification

  2. Biomass pyrolysis

  3. Biomass fermentation

  4. Biomass combustion


Correct Option: A
Explanation:

Biomass gasification involves heating biomass in a controlled environment with limited oxygen to produce a combustible gas mixture called syngas, which can be used to generate electricity or produce liquid fuels.

Which type of waste is considered hazardous and requires special handling and disposal?

  1. Municipal solid waste

  2. Industrial waste

  3. Agricultural waste

  4. Construction and demolition waste


Correct Option: B
Explanation:

Industrial waste can contain hazardous substances, such as heavy metals, chemicals, and solvents, which pose risks to human health and the environment and require specialized treatment and disposal methods.

What is the term used for the process of recovering valuable materials from construction and demolition waste?

  1. Construction and demolition waste recycling

  2. Construction and demolition waste disposal

  3. Construction and demolition waste incineration

  4. Construction and demolition waste landfilling


Correct Option: A
Explanation:

Construction and demolition waste recycling involves recovering materials like concrete, metal, wood, and gypsum from construction and demolition sites for reuse or recycling.

Which technology is used to convert organic waste into compost, a nutrient-rich soil amendment?

  1. Composting

  2. Anaerobic digestion

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Composting is a biological process that breaks down organic waste into a nutrient-rich material called compost, which can be used to improve soil structure and fertility.

What is the term used for the process of converting waste into energy through combustion?

  1. Incineration

  2. Pyrolysis

  3. Gasification

  4. Anaerobic digestion


Correct Option: A
Explanation:

Incineration involves burning waste at high temperatures to produce heat and electricity, reducing the volume of waste and recovering energy.

Which type of plastic is commonly used in food packaging and is easily recyclable?

  1. Polyethylene terephthalate (PET)

  2. High-density polyethylene (HDPE)

  3. Low-density polyethylene (LDPE)

  4. Polypropylene (PP)


Correct Option: A
Explanation:

PET is widely used in food packaging due to its clarity, strength, and recyclability. It is commonly recycled into new food containers, clothing fibers, and other products.

What is the term used for the process of recovering valuable materials from agricultural waste?

  1. Agricultural waste recycling

  2. Agricultural waste disposal

  3. Agricultural waste incineration

  4. Agricultural waste landfilling


Correct Option: A
Explanation:

Agricultural waste recycling involves recovering materials like crop residues, manure, and food processing byproducts for use as animal feed, compost, biofuel, or other valuable products.

Which technology is used to convert waste into a synthetic gas mixture that can be used as a fuel or feedstock for chemical production?

  1. Gasification

  2. Pyrolysis

  3. Incineration

  4. Anaerobic digestion


Correct Option: A
Explanation:

Gasification involves heating waste in a controlled environment with limited oxygen to produce a combustible gas mixture called syngas, which can be used to generate electricity or produce liquid fuels and chemicals.

What is the term used for the process of recovering valuable materials from municipal solid waste?

  1. Municipal solid waste recycling

  2. Municipal solid waste disposal

  3. Municipal solid waste incineration

  4. Municipal solid waste landfilling


Correct Option: A
Explanation:

Municipal solid waste recycling involves recovering materials like paper, plastic, metal, and glass from household waste for reuse or recycling.
