Dear Zeeshan

Poultry manure is a good source of energy and can be used for the production of biogas provided it is subjected to appropriate technology based on anaerobic digestion. The emphasis should be on the selection of the technology as any cattle dung based technology available in the market may not suit to poultry manure unless it is purely designed for this feed stock. Why so???? Because poultry manure has quite different characteristics than cow dung.

thanks Dinesh

What could be the effect of ammonia on biogas production yield?

what could be the best size of biogas digester to cater for 1 tonne of poultry dung ?

The biggest issue with using poultry manure only is that it hits ammonia inhibition around the 10 kg VS/m3/day mark... Ideally you want to co-digest with a feedstock that has low nitrogen content to offset that value. Otherwise, if you stay below this limit, it works ok

For this question, I suggest reading this article: Article Optimization of methane production parameters during anaerob...

Yes you can reduce your energy requirement by producing and using biogas from chicken litter.

Chicken litter has high nitrogen concentration. This high nitrogen leads to increase in the NH4 +‐N (ammonical nitrogen) because more than 60% of this nitrogen gets converted to ammonia in the process of anaerobic digestion.

I think the use is limited by the quantity of manure as the biogas produced will be low when compared to cows.

Hi guys. This is a great topic to discuss, in that way, to answer this question, I suggest reading the following articles:

Let me know if they were helpful to you folks doing a recommendation and citation of them.

Best Regards.

Dear Muhammad Zeeshan , I hope you are doing well. The poultry manure/slurry is a great candidate for biogas production when it comes to anaerobic production. The biogas approximately contains 50-60% methane depending on the properties of the feed. So that a CHP system could be used to meet the heat and electricity demand of your poultry farm simultaneously.
