Which of the following is a common waste reduction technology used in manufacturing industries?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Recycling involves processing used materials into new materials and objects, reducing the amount of waste sent to landfills and incinerators.

What is the primary objective of waste reduction technologies?

  1. To increase waste generation

  2. To reduce waste generation

  3. To dispose of waste in a safe manner

  4. To generate energy from waste


Correct Option: B
Explanation:

Waste reduction technologies aim to minimize the amount of waste produced at the source, thereby reducing the need for disposal and the associated environmental impacts.

Which of the following is an example of a waste reduction technology used in agriculture?

  1. Crop rotation

  2. Composting

  3. Anaerobic digestion

  4. Incineration


Correct Option: A
Explanation:

Crop rotation is a farming practice that involves growing different crops in the same area in sequential seasons, helping to maintain soil fertility and reduce the need for chemical fertilizers and pesticides.

What is the process of converting organic waste into a biogas mixture primarily composed of methane and carbon dioxide called?

  1. Anaerobic digestion

  2. Aerobic digestion

  3. Composting

  4. Incineration


Correct Option: A
Explanation:

Anaerobic digestion is a biological process in which microorganisms break down organic matter in the absence of oxygen, producing biogas as a byproduct.

Which of the following is a waste reduction technology commonly used in households?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Recycling is a common household waste reduction practice that involves separating recyclable materials, such as paper, plastic, and metal, from general waste for processing and reuse.

What is the process of converting waste materials into usable fuels or energy sources called?

  1. Recycling

  2. Composting

  3. Waste-to-energy

  4. Landfilling


Correct Option: C
Explanation:

Waste-to-energy technologies involve the conversion of waste materials into usable fuels or energy sources, such as electricity or heat, through processes like incineration, gasification, or pyrolysis.

Which of the following is a waste reduction technology that involves the reuse of materials or products?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Recycling involves processing used materials into new materials and objects, allowing for their reuse and reducing the demand for virgin materials.

What is the process of reducing the amount of waste generated at the source called?

  1. Waste reduction

  2. Waste management

  3. Waste disposal

  4. Waste recycling


Correct Option: A
Explanation:

Waste reduction refers to practices and strategies aimed at minimizing the amount of waste produced at the source, thereby reducing the need for waste management and disposal.

Which of the following is an example of a waste reduction technology used in the construction industry?

  1. Recycling

  2. Composting

  3. Demolition waste management

  4. Landfilling


Correct Option: C
Explanation:

Demolition waste management involves the proper handling, recycling, and disposal of waste generated during the demolition of buildings and structures.

What is the process of converting organic waste into a nutrient-rich soil amendment called?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: B
Explanation:

Composting is a biological process that converts organic waste into a nutrient-rich soil amendment through the decomposition of organic matter by microorganisms.

Which of the following is a waste reduction technology that involves the redesign of products to minimize waste generation?

  1. Eco-design

  2. Recycling

  3. Composting

  4. Landfilling


Correct Option: A
Explanation:

Eco-design, also known as sustainable design, involves the consideration of environmental impacts throughout the product lifecycle, including the reduction of waste generated during production and use.

What is the process of converting waste materials into new materials and objects called?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Recycling involves processing used materials into new materials and objects, reducing the need for virgin materials and minimizing waste generation.

Which of the following is a waste reduction technology that involves the separation and collection of recyclable materials from general waste?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Recycling involves the separation and collection of recyclable materials, such as paper, plastic, and metal, from general waste for processing and reuse.

What is the process of converting waste materials into a fuel source called?

  1. Recycling

  2. Composting

  3. Incineration

  4. Pyrolysis


Correct Option: D
Explanation:

Pyrolysis is a thermochemical process that converts waste materials into a fuel source, such as syngas or bio-oil, through heating in the absence of oxygen.

Which of the following is a waste reduction technology that involves the reduction of waste generation through changes in production processes?

  1. Process optimization

  2. Recycling

  3. Composting

  4. Landfilling


Correct Option: A
Explanation:

Process optimization involves analyzing and improving production processes to reduce waste generation, such as by minimizing material usage, reducing energy consumption, and optimizing equipment efficiency.
