Sustainable handling of sludge from waste water treatment plants
The aim of the project is to develop a sustainable handling of sludge from a waste water treatment plant by means of hydrothermal carbonization and to construct a pilot plant suitable for use in small and medium sized waste treatmment plants. The HTC process works with increased temperature and pressure which hygienises the sludge. HTC-carbon and process water are formed as residues to the process. The project is relevant for the aim of the research program and has potential to solve a waste problem. There is also potential to recycle phosforus from the HTC carbon, phosphorus which today is a scarce resource.
