Abstract: Animal waste represents a significant threat to the environment. Degradation of waste from dead animals is in general carried out in specialized facilities (rendering plants) under specific rules and guidelines. In plant proximity, undesirable malodour is usually produced during the combustion process. This odour can be effectively reduced so that it does not negatively affect the environment and society. Degradation of animal waste malodour can be processed in ozonisers, thermal combustion devices or in bio washers. The purpose of this paper is to determine the limits of exhausts that are produced during direct combustion of animal waste malodour. The level of ammonia in the combustion air is dependent on the quality of raw material processed at rendering plants where the measurements were carried out. In order to reduce the economic costs, the use of alternative fuels (animal fat, heavy fuel oil) is recommended.
