Question
What's the difference between feedstock and substrate in a biogas plant?
Solution
In a biogas plant, both feedstock and substrate are used, but they have different roles and meanings.
-
Feedstock: This term refers to the raw materials that are fed into the biogas plant for the production of biogas. These can be various types of organic waste such as manure, sewage sludge, food waste, or energy crops. The feedstock is the primary source of organic matter that will be converted into biogas.
-
Substrate: This term is often used interchangeably with feedstock, but it has a more specific meaning. The substrate is the material that is actually undergoing the biological process of anaerobic digestion in the biogas plant. It is the feedstock after it has been processed and prepared for digestion. This includes processes like size reduction, homogenization, and sometimes pre-treatment to increase the efficiency of the digestion process.
In summary, the main difference between feedstock and substrate in a biogas plant is that feedstock refers to the raw materials that are input into the system, while substrate refers to these materials after they have been prepared and are undergoing the process of anaerobic digestion.
