RES systems offer many benefits.
Biogas – A Renewable Fuel Source
The Anaerobic Digestion process produces a biogas, consisting of methane, carbon dioxide and traces of other gases. This biogas can be used directly as fuel, in combined heat and power gas engines to create electricity to be used on site or exported to the grid; or upgraded to natural gas-quality bio-methane “Renewable Natural Gas” (RNG); or can be compressed and used for transportation fuel.
Digestate – Natural fertilizer
A nutrient-rich digestate is produced from the Anaerobic Digestion process. Both liquid and solid residue are commonly used as natural fertilizer products. The solid (fibre residue) is used as a soil amendment, the liquid digestate is used as a natural fertilizer product. Other common uses for the odorless, and pathogen free residue are livestock bedding, and building materials.
Green House Gas Emission
By capturing methane produced through anaerobic digestion, each project is reducing the amount of greenhouse gases that would otherwise be released into the atmosphere. This process can be used to create a carbon credit, or GhG offset.
