The primary product of a Bio-CNG plant is Bio-CNG, which is a type of renewable natural gas made from organic waste material. Bio-CNG is produced through the process of anaerobic digestion, in which microorganisms break down organic matter in the absence of oxygen. The resulting biogas is then cleaned, conditioned, and compressed to produce Bio-CNG, which can be used as a transportation fuel or for other purposes.
In addition to Bio-CNG, a Bio-CNG plant may also produce other products as by-products of the anaerobic digestion process. These can include:
Compost: The solid residue produced during the anaerobic digestion process can be processed into a nutrient-rich compost that can be used as a soil amendment in agriculture.
Fertilizer: The liquid residue produced during the anaerobic digestion process can be used as a fertilizer for crops.
Electricity: Some Bio-CNG plants may also have facilities to generate electricity from the biogas produced during the anaerobic digestion process. This electricity can be used on-site or sold to the grid.
Heat: The heat generated during the anaerobic digestion process can also be captured and used to heat buildings or other facilities on-site.
