Abiotec II - Antibiotics in Manure and Digestate - Program
The workshop was part of a Thuringian project called ABIOTEC II, which aimed to addess methods and technological solutions for reduction of antibiotics in environmental compartments
Protecting livestock in modern intensive animal husbandry is typically based on the use of specialized veterinary pharmaceuticals. Through the use of the excretion products, there is a direct or indirect application onto agricultural areas and into the water cycle.
The fermentation of manure might be suitable as a process, which reduces the potential for environmental toxicological harm from certain substances, but it can also pose environmental risks. Are there other methodological approaches or procedures to reduce the pollutant input and thus to reduce the pollution? Which factors should be prioritized in order to be used in everyday agricultural life? Does reducing or even eliminating antibiotics solve the problem? And perhaps most importantly – how can we monitor it?
On April 17th and 18th in Weimar researchers from Germany, Netherlands, Denmark and USA shared their results on topics such as how antibiotics affect soil, the alteration of the soil microbiome and the role of antibiotic resistant bacteria and genes, as well as effects they have observed in treatment options, and approaches for monitoring.
