“…Moreover, an increase in the mass fraction of meat and bone meal and poultry litter in input waste enhances the calcium content of ash. The high phosphorus and calcium content of MBMderived ash is consistent with the research of Fryda et al who studied the burning of MBM with two types of coal in a laboratory-scale fluidized bed combustor (Fryda et al 2007). Poultry litter enriches the potassium content of ash, as shown by Guerra-Rodriguez et al who characterized the nutrient content of compost produced by the co-composting of chestnut burr, leaf litter and solid poultry manure (Guerra-Rodriguez et al 2001).…”

“…The meat and bone meal (MBM) that is formed during this process is granular and sticky, contains bone fragments, and consists of large amounts of volatile matter and ash. Importantly, MBM is a rich source of calcium and phosphorus (Fryda et al 2007;Wu et al 2009;Conesa et al 2005). The total production of meat and bone meal in the European Union is approximately 3.5 million tonnes per year (Coutand et al 2008).…”

Recently there has been an increase in consumption of meat, especially poultry. This results in an increase in the quantity of waste, including waste feathers. Waste from the meat industry are hazardous, which must be disposed of in accordance with the law. Wastes from the meat industry normally consist of valuable elements such as phosphorus, calcium, potassium, magnesium (macronutrients), and iron, copper, zinc, manganese (micronutrients), which after suitable processing can be used for the purposes of fertilization. The paper presents the results of thermal treatment of feathers with meat and bone meal and feathers with poultry litter in a high scale rotary kiln. Mixtures of wastes were incinerated in temperature range from 600 to 900°C for about 20-25 min. The resulting ashes were characterized by a high content of phosphorus (4-17%), calcium (17-30%) and potassium (0.6-3.6%). The study revealed that the selection of process parameters allows for obtaining ash with controlled and desired composition of macro and micronutrients, moreover, it is safe in terms of sanitary.

“…A high content of phosphorus in ash is observed with a smaller share of poultry litter in the mixture (due to low P content of poultry litter compared to feathers and MBM). Ash after combustion of meat-bone meal contains nearly exclusively hydroxyapatite, which consists in a significant amount of phosphorus and calcium (Fryda et al 2007). For this reason, meat-bone meal is a rich source of these macronutrients.…”

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.

“…The use of MBM as secondary fuel supplementing coal in a fluidized bed combustor is the option most frequently evaluated (Cummins et al 2006, Fryda et al 2007, Gulyurtlu et al 2005, McDonnell et al 2001, Miller et al 2006, Senneca 2008, Skodras et al 2007). Mainly due to concerns for air emissions related to combustion and incineration of MBM, alternative options were proposed, including pyrolysis and gasification.…”
