Definitions
- Term
Anaerobic Digestion
- Meaning
The biological process of breaking down organic matter in the absence of oxygen, carried out by anaerobic microorganisms.
- Term
Biogas
- Meaning
A mixture of gases, primarily methane and carbon dioxide, produced by the anaerobic decomposition of organic waste.
- Term
Digestate
- Meaning
The residual solid or semi-solid material left after the anaerobic digestion process, rich in nutrients and useful as a fertilizer.
