Abstract
The use of sludge in Swedish agriculture has steadily increased over the past twenty years. The thesis poses the question of how this has been achieved and what negotiations between actors have taken place to enable sewage sludge as a resource. The thesis argues that the realisation of a common understanding of what sludge is plays a significant role in finding a future use. This realisation is continuously challenged by other ways in which sludge can be understood.
