This biofuel is transported by our Tankers and is then loaded into Anaerobic Digester tanks, in which it is broken down by anaerobic bacteria over time. This usually takes around 40 days, and may change depending on the AD plant. During this breakdown, methane is produced by the activity of the bacteria. This methane is extracted from the digester and is known as biogas. This biogas can be used for electricity, gas to grid, heating, or even as biomethane for transport.
Once this process is complete, a by-product is left behind, called digestate. Digestate is the fibrous material left over from the food waste, which is then removed and spread to agricultural land as a fertiliser.
