Dry Fermentation (Anaerobic Digestion)
Kedco specialises in dry fermentation partnering with a leading supplier who has installed 12 plants in continental Europe.
Dry fermentation is a series of processes in which micro-organisms break down biodegradable material in the absence of oxygen. This dry fermentation process utilises renewable resources as a feedstock to produce a methane and carbon dioxide rich biogas suitable for energy production. The nutrient-rich solids left after digestion can be used as a fertiliser and compost.
Emission of greenhouse gases are reduced by the dry fermentation process in a number of ways including, replacement of fossil fuels, reduction of landfill methane emissions, displacing chemical fertilisers and reducing vehicle movements.
The United Nations Development Programme has recognised dry fermentation facilities as one of the most useful decentralised sources of energy supply, as they are less capital intensive than large powerplants. Power generation via dry fermentation is eligible for ROCs.
Almost any organic material can be processed with dry fermentation. This includes biodegradable waste materials such as waste paper, grass clippings, leftover food, sewage and animal waste. The plants comprise a number of anaerobic digesters and CHP plants.
