What is Anaerobic Digestion?

Anaerobic digestion - what is it? The success story of anaerobic digestion is getting around. 

That means that more and more people are asking the question; "What is Anaerobic Digestion?"

At this blog we have a habit of quoting others, because very often what we would say has been said already, and usually very succinctly as well. 

We think that the following online excerpts should amply help answer the question of the day, namely; "What is Anaerobic Digestion?"

Definitions of Anaerobic digestion

Anaerobic digestion is the natural process in which microorganisms break down organic matter in the absence of air (an anaerobic environment). 

Anaerobic digestion creates usable products such as biogas and digested material. via Frequent Questions about Anaerobic Digestion

Anaerobic digestion is a biological process whereby bacteria break down organic material into more basic compounds without requiring oxygen as a component of the process.

With the ... via Anaerobic Digestion: Turning Waste into Renewable Energy

There are also different types of anaerobic digestion, such as:

Low-temp anaerobic digestion

Conventional anaerobic biodigesters do a fine job of breaking manure down into basic elements, but they need temperatures of 35 to 40 C. For high-speed biodigesters, it’s more like 50 C. 

All of this biodigestion is good for the environment, but the supplemental heat is a major operating cost, no matter what fuel is burned.

To further complicate matters, conventional anaerobic digesters become chemically unstable and lose their ability to function should the temperature fluctuate.

However, a biological breakthrough has eliminated the need for energy input. It’s called low-temperature anaerobic digestion and requires temperatures of 20 to 25 C. via Low-temp anaerobic digestion
