Anaerobic Digestion - Benefits• Minimal additional water required• Material stays stationary, while bacteria (percolate)is sprayed over it to accelerate the decompositionprocess• The input material is reduced by up to 40% andenergy is extracted in the process• The end product (digestate) can be furthercomposted to make commercial grade compost orcan be land applied as a fertilizer• Gaseous/Odor emissions are captured and treated© <strong>BIOFerm</strong> <strong>Energy</strong> <strong>Systems</strong>12/13/2012CONFIDENTIALSlide 12
