Anaerobic Digestion Process Steps: The 4 Stages Explained
Anaerobic digestion takes place through four closely connected biological process steps: hydrolysis, acidogenesis, acetogenesis and methanogenesis. Together, these microbial stages convert complex organic material into biogas—principally methane and carbon dioxide—and digestate. New to the subject? Start with our complete introduction to anaerobic digestion. This article concentrates specifically on the biochemical process steps, the compounds produced at each stage […]
How to Eliminate CO2 from Biogas? “Scrubbing” Explained
Here we explain how to Eliminate CO2 from Biogas, (or CO2 Scrubbing). Biogas can be upgraded to pipeline natural gas quality (biomethane) for use as a renewable natural gas, but as part of the upgrading process, it will be necessary to remove the carbon dioxide (CO2) from the biogas. This upgraded gas may also be […]
