Experimental and Predicted Methane Yields from the Anaerobic Co-Digestion of Animal Manure with Complex Organic Substrates

Abstract

Anaerobic co-digestion of animal manure with complex organic substrates can improve the economic viability of farm treatment processes. Co-digestion is a method that increases the buffering capacity of substrate mixtures and adds essential nutrients that can substantially improve methane yields. However, despite the benefits of co-digestion, the overall impact that additional materials have on manure-only fermentation processes is not known.
