Biodegradation Quiz

5 Questions

What is biodegradation?

A biologically catalyzed process by which organic substances are broken down into smaller compounds by living organisms

What is the difference between composting and biodegradation?

Composting is a natural breaking down process of organic wastes by microorganisms under controlled conditions, while biodegradation is a natural breaking down process of organic waste by microorganisms

What is the term used when biodegradation is complete?

Mineralization

What is a compostable product required to do in a composting system?

Biodegrade within 180 days and leave no toxicity in the soil

What are the degradative abilities employed in biodegradation used for?

To convert waste materials into more acceptable and manageable forms or to produce useful end products

Study Notes

Biodegradation

Biodegradation is the process of breaking down organic materials by microorganisms, such as bacteria, fungi, and yeast, into simpler compounds.

Composting vs Biodegradation

Composting is a specific type of biodegradation that involves the aerobic decomposition of organic matter, typically in a controlled environment, to produce a stable humus-like product.
Biodegradation is a broader term that encompasses various types of decomposition, including anaerobic decomposition, which occurs in the absence of oxygen.

Completion of Biodegradation

The term used when biodegradation is complete is "mineralization", which refers to the conversion of organic matter into inorganic compounds, such as carbon dioxide, water, and minerals.

Compostable Products

A compostable product is required to break down into carbon dioxide, water, and biomass at a rate consistent with known compostable materials, and leave no toxic residues, in a composting system.

Applications of Biodegradation

The degradative abilities employed in biodegradation are used for various purposes, including waste management, environmental remediation, and the production of biofuels and biochemicals.
