Resource recovery from wet organic waste

​In moving towards a sustainable society, it is important to utilize resoruces wefficiently while preserving the productivity of natural systems. For wet organic waste flows, methods are needed that can handle wet flows and produce valuable products that enable risk-free recycling of nutrients with minimal impact on the environment from a systemis perspective.

In the research group, research is performed on hydrothermal methods for recovery of resources from wet organic waste flows. The enviuronmental performance from a life-cycle perspective is studied for methods like supercritical water oxidation (SCWO) and hydrothermal conversion (HTC) and for flows such as sewage sludge and industrial waste flows (from e.g. forest and food industry). The methods enable recovery of e.g. fuels, chemicals or heat from the waste flows at the same time as recovery of nutrients is possible without risk of ecocycle contamination. The research shows that large environmenetal gains are possible if processes are formed optimally and in consideration of the surrounding system. It is crucial the products can be utilised.

Research is performed in close cooperation with industry and with Professor Jefferson W Tester at MIT (Department of Chemical Engineering, Massachusetts Institute of Technology, Cambridge, USA). Both Magdalena Svanström and Morgan Fröling spent their PostDoctoral time as Wallenberg Postdoctoral Fellows in Environment and Sustainability at MIT (in 2001 and 2004-2005).
