Anaerobic Digestion of Poultry Processing Wastes for Bioenergy and Nutrients Recovery
Abstract
Anaerobic digestion (AD) is an attractive technology that can be used to recover energy (in form of methane in biogas) and nutrients from waste poultry blood. One challenge with treating high-strength high-protein wastes is the production of total ammonia nitrogen (TAN) during decomposition. The TAN severely inhibits methane producing bacteria and results in accumulation of fatty acids, which destabilizes the digester and causes AD process failure. This dissertation proposed and examined several ways to manage these drawbacks, namely, use of biocarriers, two-stage process, and struvite precipitation.
