Enzymatic Pre Treatment of Chicken Feather Waste to Generate Biogas
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2021, Vol 5, Issue 5
Abstract
Feather is produced in large amounts as a waste in poultry slaughterhouses. Only 60 70 of the poultry slaughterhouse products is edible for human. 16 20 of the slaughterhouse by products contains keratin from this 7 9 consists of feather with 50 70 moisture content. Treatment of poultry feather anaerobically is a challenge, because of the complex, rigid, and fibrous structure of keratin, the main component of feathers. Under anaerobic conditions, poultry feather degrades poorly, which is the main obstacle for anaerobic digestion. The reported value of chicken feather methane potential is 0.19 – 0.20Nm3 kg VS, which is only one third of the theoretical value. It is an excellent raw material for biogas production due to high protein content. Dried chicken feathers contain about 90 proteins with 0.2 methane potential m3 kg 1 VS added and 0.05 methane potential m3 kg 1 wet weight . The keratin content of feather is difficult to digest, so physical, chemical and or biological pre treatment are needed in practice, which have to be set according to the utilization method. Feather was degraded with the help of enzyme and then digested in anaerobic bioreactors in different ratios. We used cattle slurry as control without feather. Our main objectives for this study were to determine the effect of enzymatic pre treatment, biogas methane potential of feather waste and the most effective treatment ratios. Chicken feather waste can also be digested or used with other feedstock as a co digestion substrate.
