Livestock effluents have always been spread as fertiliser on fields. But they can also transmit diseases to humans and animals, for example, over 100 pathogenic micro-organisms (bacteria, viruses, parasites) have been identified in pig slurry. To destroy the main causes of illness and avoid epidemics, scientists use heat exchangers for thermal treatment of the slurry, a well known technique that they are trying to make more energy efficient.
