Re: Is it possible to produce energy with chicken manure?

Yes, but the chemistry is different than most manures. Chicken manure is very 
high in urea. As the methane gas is produced during anaerobic digestion, a 
significant amount of ammonia is also produced. Ammonia burns and produces 
energy almost as well as methane (about 450 BTU/sft3 compared to 600
BTU/sft3 for methane), but produces NO2 as a combustion 
product. Oxides of nitrogen must be removed from the exhaust, as they are 
dangerous to human health and the environment. This is very expensive. It is 
also difficult to pre-treat the digester gas because the similar physical and 
chemical properties of ammonia and methane make them difficult to separate. 
There is also the problenm of odor control. Although there is nothing pleasant 
about the smell of rotting chicken manure, burning chicken manure is many times 
worse.
