| Περίληψη: | Anaerobic digestion (AD) enables the valorization of organic waste, such as poultry manure (PM), into biogas and nutrient-rich digestate. However, the high total ammonia nitrogen (TAN) content of PM is a significant bottleneck, as high free ammonia (FA) levels inhibit methanogenesis. This review provides a quantitative synthesis of reported batch and continuous AD trials to identify operating conditions associated with high methane yields, focusing on the effects of FA concentrations and HRT on methane yield. Data from 55 continuous-reactor trials were consolidated and filtered by methane yield percentile to focus on high-performance cases, with mono-digestion and co-digestion systems analyzed separately. The novelty of this review lies in the integrated analysis of operational parameters to identify practical operating windows associated with high methane yields. For mono-digestion, methane yields above 300 L CH (Copyright © 2026 Elsevier Ltd. All rights reserved.) |
