Anaerobic digestion (“AD”) is the process of using organic materials including food, agricultural wastes, and crops.
These biodegradable wastes are broken down by naturally occurring micro-organisms in the absence of oxygen-producing methane-rich biogas. This biogas is used to produce heat and electricity or upgraded to methane and injected into the gas grid.
The AD process also produces a nutrient-rich substrate that is used as a substitute for chemical fertilisers. A summary of the AD process is shown below.
*CO2 emissions are approximately 90% lower than natural gas. The input organic material utilised in the conversion process absorbs CO2 from the atmosphere as part of the natural carbon cycle.
