EU politics on wastewater treatment will result in increased amounts of waste activated sludge (WAS) in order to meet the new water discharge limits. Therefore, measures to deal with sludge disposal have to be developed. The problem is that WAS is poorly degraded during anaerobic digestion, because the cells do not disrupt. Pre-treatment of the WAS has great potential to optimise the anaerobic digestion. The objective of this project is to develop innovative pre-treatment methodologies of the WAS in order to: Reduce sludge quantities by at least 50%,Optimise renewable energy production by 50-100%, and to reduce the level of organic pollutants and pathogenic microorganisms. Dissemination of the results will be secured by focusing on methods beneficial to the economy of wastewater plants and other end-user industries. The project contributes to meet the EU objectives for production of renewable energy and thereby also to reduce the impact from CO2 on global warming.
