Utilisation of poultry litter as an energy feedstock

This paper examines poultry litter (PL) as a resource in fuel quality terms and illustrates how the small scale application of fluidised bed technology solves both energy and waste problems, while producing a nutrient rich ash. PL was found to have a higher heating value (HHV) of 18 GJ t−1 on a dry basis (db). On an as received basis (ar), it had an ash mass fraction of 9% and the elemental phosphorous content of the ash was 110 g kg−1. The resultant mineral matter can be utilised as a nutrient substitute for mineral fertiliser.

► ∼30 samples of poultry litter were analysed and compared to reported results.
► Fuel quality was determined and possible combustion issues were discussed.
► Poultry litter was identified as an indigenous renewable biomass energy source.
► Small scale application of FBC was shown to be useful in waste management.
► Potential for nutrient recycling in the form of phosphorous was identified.
