The safe disposal of sewage sludge- a residue of the wastewater treatment process- is a pressing global challenge that bears constantly rising cost due to increasing environmental standards. At the same time sewage sludge offers a great potential for green energy production and recovery of valuable nutrients for fertilization.
The TerraNova® Ultra technology, which is based on Hydrothermal Carbonization, allows for energy efficient sludge drying to a small amount of solid fuel and integrated Phosphorous recovery – thus treatment and disposal cost are reduced.
