Biogas Capture from Animal Manure

Abstract

Prior to the 1970s, the principle use of anaerobic digestion across the world was in manure management. Whereas developing countries – principally India and China – used “biogas technology” to extract fuel from manure, developed countries used anaerobic digestion mainly to stabilize the manure, with little concern for the methane that was generated in the bargain.

This chapter recapitulates this background and describes the low-rate and the high-rate anaerobic digesters currently in use to capture biogas from animal manure.
