Website of the institute of municipal and industrial wastewater management (aww) at the University of Hamburg-Harburg (TUHH). Their research interest is directed towards efficient sanitation solutions that preferably produce reusable material rather than waste. The focus is both on municipal and industrial wastewaters with a view on the whole process and mass flows. This includes research on terra preta, too. See also http://www.tu-harburg.de/susan/downloads/index.html for a list of publications on sustainable sanitation.
