From waste to useful biogas.
Biogas is produced when suitable organic material breaks down in an oxygen-free digester. The resulting gas can be collected and used as an energy source.
Organic Material
Suitable biodegradable material is prepared for the digester.
Digestion
Material decomposes in the sealed digester without oxygen.
Gas Collection
The biogas produced is captured and directed through the system.
Useful Energy
The gas can then serve suitable cooking, heating, lighting and other applications.
