post-slaughter wastes - Opis:
- Chicken feathers generated in large quantities by the poultry industry are hazardous for the natural environment because of their poor digestibility and their potential as a source of microbiological pathogens. Currently, the main method of feather waste management is the production of feather meal by steam pressure cooking. This technology requires a high energy input. The high costs of hydrothermal degradation of these wastes are conducive to finding other alternative possibilities of poultry wastes management. This paper describes the feather-utilization method with calcium oxide treatment in a rotational reactor, which leads to the production of organic-mineral fertilizers. The effectiveness of this method has been tested in chemical and microbiological analyses. The results of the study confirm the possibility of the environmental usage of utilization-products.
