Anaerobic Digestion

From the National Non-Food Crops centre (NNFC), this factsheet reviews the potential of anaerobic digestion technology and its suitability to UK farming and waste systems. The factsheet describes the application of anaerobic digestion (AD), which is the conversion of organic non-woody material in the absence of oxygen into stable and commercially useful compounds. AD feedstock can be unwanted ‘wastes’ such as slurry or food waste, or energy crops grown specifically for feeding the digester. The outputs from the digestion process are biogas and digestate.
