Chicker Feathers to Biogas: A PhD thesis

Chicken is something that almost everybody love and eat, regardless of the culture and religion. We eat the meet, but, there are a lot of wastes over, in which, feather is a major one!

In the last 30 years, the production of chicken feather was increased from 1,5 to 5 million tons per year. So the question is what to do with this feather! Our PhD candidate Gergely Forgacs took this question seriously as part of his PhD thesis and he is defending a few days. His focus was on biogas. The feather from slautherhouses can produce about 180 m3 biogas (methane) per ton of the material (volatile solid), and he could improve it to 400 m3 methane gas. Let's hope he can produce well both the biogas and also a PhD title for him from the feather :)

The thesis:
Biogas Production from Citrus Wastes and Chicken Feather: Pretreatment and Co-digestion
