“…In the ash after combustion of poultry litter and feathers, a high level of potassium and magnesium is observed (Kelleher et al 2002, Abelha et al 2003. Poultry litter and waste feathers can be used as a major source of these elements.…”

Recently, the increased consumption of poultry meat in the EU has been observed. Short cycle of poultry meat production allows adjusting the level of production to demand. With the increase in the meat production the amount of generated waste that has to be disposed because they pose a risk to the environment also increases. The work presents the possibility to produce a mixture of feathers, meat-bone meal and poultry litter that can be used for energy purposes (alternative fuel). Moreover, the composition of the ashes after combustion will be similar to phosphorus-potassium fertilizers offered for sale. The resulting granules are characterized by a calorific value in the range 13.1-13.3 kJg -1. The ash after its combustion contained 11.33-13.38% of phosphorous, 4.94-5.67% of potassium, 31.85-32.69% of calcium and 2.07-2.51% of magnesium. Moreover, the ash contained 0.45-0.46% of iron, 0.10-0.11% of manganese, 0.11-0.14 of zinc and 0.02% of copper. Mineral combusted residue of this type of granules has a low content of heavy metals and can be used as an additive to fertilizers and soil improvers, in order to enrich their composition in valuable macro-and micronutrients.

“…PW from poultry farming includes a mixture of poultry manure (excreta), bedding materials (e.g., wood shavings, sawdust, straw, pine or rice husk), waste feed, dead birds, broken eggs, and feathers removed from poultry houses [2,3]. Poultry manure (or chicken manure) is an organic waste, mainly feces and urine of chicken, whereas poultry litter refers to a mixture of poultry manure, bedding materials, spilled feed and feathers [1].…”

Regression Model to Predict the Higher Heating Value of Poultry Waste from Proximate Analysis

et al. 2018

Improper land application of excess poultry waste (PW) causes environmental issues and other problems. Meanwhile there is an increasing trend of using PW as an alternative energy resource. The Higher Heating Value (HHV) is critical for designing and analyzing the PW conversion process. Several proximate-based mathematical models have been proposed to estimate the HHV of biomass, coal, and other solid fuels. Nevertheless, only a small number of studies have focused on a subclass of fuels, especially for PW. The aim of this study is to develop proximate-based regression models for an HHV prediction of PW. Sample data of PW were collected from open literature to develop regression models. The resulting models were then validated by additional PW samples and other published models. Results indicate that the most accurate model contains linear (all proximate components), polynomial terms (quadratic and cubic of volatile matter), and interaction effect (fixed carbon and ash). Moreover, results show that best-fit regression model has a higher R 2 (91.62%) and lower estimation errors than the existing proximate-based models. Therefore, this new regression model can be an excellent tool for predicting the HHV of PW and does not require any expensive equipment that measures HHV or elemental compositions.

“…The significant atmospheric pollutants considered in this assessment were nitrogen oxide (NO x ), carbon monoxide (CO) and sulphur dioxide (SO 2 ). Emission rates for the unit were calculated based on monitoring experiments and used as input for the model (Abelha et al, 2002). These values are given in Table 4.…”

Gaseous emissions from the fluidised bed co-combustion of 50% w/w chicken litter and peat were monitored and recorded. Emission data were used to create a dispersion model for a proposed site on a poultry farm in Ireland. Variables within the combustion unit influenced both combustion and emission levels of pollutants such as SO 2 and NO x , CO. Concentrations of atmospheric pollutants decreased with use of the correct ratio between fluidising and secondary air. Dispersion modelling combustion at a proposed poultry unit predicted that ground level concentrations for the set of emissions data would be below the limits and guidelines set by air quality standards.of
