Forget milk – an average cow can produce up to 3kwh of electricity every day.
Networking platform Renewity says this power, produced through the anaerobic digestion of manure, can then be sent to the electricity grid.
It says the renewable form of energy generation has the advantage of creating gas, liquid and fibrous fertiliser byproducts, opening up another stream of revenue for farms.
The organisation also says efficient anaerobic digestion can also be used to reduce the odour levels of a facility and to remove phosphorous and other metals from waste.
The organisation says the high temperature of anaerobic digestion systems can decrease the number of disease-causing pathogens in manure slurry.
