Why Poultry Waste Can Reduce Biogas Production: Biochemical Inhibition, Feedstock Quality, Digester Instability and Practical Solutions
A naerobic digestion (AD) is an established biological process that converts biodegradable organic matter into biogas under oxygen-free conditions. The process recovers renewable energy from poultry manure, poultry litter, and other organic residues while reducing the amount of waste requiring disposal. The resulting biogas typically contains methane (CH₄) and carbon dioxide (CO₂), along with smaller quantities of hydrogen sulphide (H₂S), water vapour and other trace compounds. After appropriate cleaning and upgrading, biogas can be used for heat and electricity generation or converted into compressed biogas (CBG), depending on its quality and the plant configuration. Poultry waste has considerable potential as an anaerobic digestion feedstock because it contains organic matter, nitrogen and other nutrients. However, its suitability for biogas production depends on more than the quantity of waste available. Poultry manure can contain high concentrations of nitrogen, rapidly degradable ...
