We at HSY are developing innovative methods for utilizing the nutrients and carbon from municipal wastewater in order to enhance circular economy. The pyrolysis of sewage sludge is an important strategic project for HSY. Together with RAVITA-technology HSY has formed a concept where nutrients and carbon from wastewater can be recycled more efficiently. This video presents a pilot plant built at the Ämmässuo eco-industrial center to test the pyrolysis of municipal wastewater sludge.
