Combustion of poultry derived wastes for smart energy recovery

Due to the stringent and explicit European environmental legislation about land spreading of nitrates, the direct land application of the poultry litter is not anymore the most appropriate disposal technique. We investigated the combustion of pure common poultry derived wastes and mixtures of these with olive pomace in a domestic burner optimized for wood pellet combustion. Typical waste and product streams based on combustion tests were characterized for the different mixtures (100%w to 50%w poultry litter content). We observed that the high CO emissions compared to wood pellet combustion but can be reduced by optimizing combustion; the size distribution function of particle is not influenced by poultry litter content; the inorganic elements are mainly concentrated in ashes.
