A relevant part of the literature reports experimental experiences of thermo-chemical employment of chicken
manure i. e. gasification and pyrolysis [12, 13, 14]; under specific conditions, the gasification process can be able to
enhance the production of a hydrogen pure flue gas useful for energy [15]; also evidence of direct combustion are
available worldwide [16]. From the analysis of the state of the art it appears that the gasification of poultry waste is
today mainly related to small-scale and laboratory applications [14]; however a small farm based gasification plant
is operative in Netherlands [17]. In order to consider animal waste (e.g. poultry litter) as an alternative energy
source, both the energetic and physicochemical characterization of manure assume a relevant role; typical values for
the Higher Heating Values (HHVs) on a dry basis (experimental) varies between about 12,000 and 14,000 kJ/kg
while Lower Heating Values (LHVs) on a we
