Based on these results, it can be concluded that the type of the incinerated material mostly determines the composition of the obtained ash. Each material has a different composition of macronutrients. Meat-and-bone meal has a high content of phosphorus and calcium, and poultry litter contains potassium. Because of the large resistance of BMS-708163 in relation to temperature, in the case of feather burning, macronutrient content is determined by temperature value. Dependence of elements content on temperature was also observed during the incineration of poultry litter. The high calorific value of meat and bone meal causes that the ignition process takes place automatically and it is entirely incinerated. The micronutrients content is affected by the type of material being incinerated and the process temperature. Feathers are the richest source of zinc, manganese, copper and iron. Increased temperature causes the increased content of these elements in the ash. The time of the process has no effect on the content of macro- and micronutrients.
