Abstract: This dissertation used a life cycle assessment to examine alternative process chains for the recycling of sewage sludge and to compare them with the mono-incineration. The determination of the emission profiles for sewage sludge treatment by hydrothermal carbonization (HTC) and pyrolysis as well as for the different application paths of the resulting materials was carried out in eight different scenarios. Overall, both processes showed ecological advantages over mono-incineration, so that pyrolysis and HTC represent potential recycling technologies for a sustainable waste management.
