Agricultural production and production of food of animal origin in biotechnological processes generate large quantity of by-products – animal waste. These products have negative influence on the environment, but also present a threat to public health, as they are a source of infectious and zoonotic diseases. Proper management of animal waste is of utmost importance. According to the European and domestic legislation they are divided into three categories. The system of animal waste management has not been established in Serbia yet what has negative effects on production of safe food, protection of the environment and economics. It is of utmost importance to introduce modern and safe methods of waste management, given that certain categories of by-products are classified as biohazadous waste. Currently in the countries with developed cattle breeding and advanced biotechnology the methods for microbiologic composting are applied in closed reactors – biovators. Biovators are constructed as closed tank systems equipped with automatic devices that follow and regulate basic conditions during the process, like for example optimal moisture, temperature, mobility of the content and the ratio of animal components and lignocelluloses materials. The capacity is around 500 kg/daily and may produce high quality compost in 14 days without the use of industrially produced microorganisms. The aim of this paper is to present safe, economical and ecological justified procedures in management of hazardous animal waste to the experts and interested public.
