Anaerobic Digestion
Anaerobic Digestion (AD) is a process by which microorganisms break down biodegradable material to produce biogas which is combusted to generate electricity and heat or processed in to renewable Biomenthane and transport fuels. The digestate or natural fertiliser, full of nutrients is utilised as a fertiliser and can be directly applied to croplands.

Biogas
Biogas is produced by the anaerobic digestion process. Biogas is produced from the raw material such as agricultural residue, manure, plant material, slurries and silages. Biogas is a renewable energy source of energy that can be used to generate electricity, heat or converted to Biomethane. Biogas composes primarily of methane with CO2 (carbon dioxide) and small quantities of other gasses.

Biomethane
Biomethane is produced when biogas is purified (or upgraded) to remove CO2 and other gasses. The purified or upgraded biogas that is free from contaminants is called biomethane also known as Renewable Natural Gas.
