Which of the following is a common method for recycling organic materials and food waste?

  1. Anaerobic Digestion

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: B
Explanation:

Composting is a widely adopted method for recycling organic materials and food waste. It involves the controlled decomposition of organic matter by microorganisms, resulting in a nutrient-rich compost that can be used as a soil amendment.

What is the primary purpose of anaerobic digestion in the context of organic waste recycling?

  1. Generating electricity

  2. Producing biogas

  3. Creating compost

  4. Reducing greenhouse gas emissions


Correct Option: B
Explanation:

Anaerobic digestion is a process in which organic materials are broken down by microorganisms in the absence of oxygen. The primary purpose of anaerobic digestion in organic waste recycling is to produce biogas, a renewable energy source composed primarily of methane and carbon dioxide.

Which technology utilizes enzymes to break down organic materials into simpler compounds for recycling?

  1. Pyrolysis

  2. Gasification

  3. Hydrothermal Carbonization

  4. Enzymatic Hydrolysis


Correct Option: D
Explanation:

Enzymatic hydrolysis is a process that employs enzymes to break down organic materials into simpler compounds, such as sugars and amino acids. This technology is commonly used in the recycling of organic waste to facilitate further processing and utilization.

What is the primary objective of hydrothermal carbonization in the context of organic waste recycling?

  1. Producing biochar

  2. Generating electricity

  3. Creating compost

  4. Reducing greenhouse gas emissions


Correct Option: A
Explanation:

Hydrothermal carbonization is a thermochemical process that converts organic materials into a carbon-rich solid known as biochar. The primary objective of hydrothermal carbonization in organic waste recycling is to produce biochar, which has various applications, including soil amendment, carbon sequestration, and energy production.

Which of the following technologies involves the thermal decomposition of organic materials in the absence of oxygen?

  1. Pyrolysis

  2. Gasification

  3. Incineration

  4. Anaerobic Digestion


Correct Option: A
Explanation:

Pyrolysis is a thermochemical process that involves the thermal decomposition of organic materials in the absence of oxygen. This process converts organic matter into various products, including bio-oil, syngas, and char.

What is the primary product obtained from the gasification of organic materials?

  1. Biochar

  2. Syngas

  3. Compost

  4. Biogas


Correct Option: B
Explanation:

Gasification is a thermochemical process that converts organic materials into a gaseous mixture known as syngas. Syngas primarily consists of hydrogen, carbon monoxide, and carbon dioxide and can be used as a fuel or as a feedstock for various chemical processes.

Which technology utilizes microorganisms to break down organic materials into simpler compounds for recycling?

  1. Pyrolysis

  2. Gasification

  3. Hydrothermal Carbonization

  4. Biological Treatment


Correct Option: D
Explanation:

Biological treatment is a process that employs microorganisms, such as bacteria and fungi, to break down organic materials into simpler compounds. This technology is commonly used in the recycling of organic waste to facilitate further processing and utilization.

What is the primary objective of vermicomposting in the context of organic waste recycling?

  1. Producing biochar

  2. Generating electricity

  3. Creating compost

  4. Reducing greenhouse gas emissions


Correct Option: C
Explanation:

Vermicomposting is a process that utilizes worms to break down organic materials into a nutrient-rich compost. The primary objective of vermicomposting in organic waste recycling is to create compost, which can be used as a soil amendment to improve soil fertility and structure.
