• KompaGG-N - Complete Treatment of Manure and Digestate: Process Developement in Consideration of Regional Substance Flow Concepts for Nutrients and Pollutants

  The goal of KompaGG-N is the development of a robust and economically viable process chain for a complete treatment of manure and digestate. The regional and case specific nutrient flows (mainly nitrogen) play an important role in this regard, for the process chain is to be locally embedded. Additionally the influence of treatment on the remain of pollutants such as genes and bacteria resistant to antibiotics is investigated.

• OSCAR - Online Modeling, Simulation and Remote Control System for environmental technologies on-board (Cruise) Ships (OSCAR)

  OSCAR aims to take a decisive development step towards improving the quality of environmental protection on board (cruise) ships by extending maritime digitalisation to on-board environmental process technology. The aim is to develop and test a system that will enable monitoring and, in perspective, remote control of the complex, mainly biological treatment processes from the relevant environmental segments of waste water and organic waste on board (cruise) ships. Initial point for a later centralized fleet management of the treatment processes. Furthermore, the supply of an additive based on digestate for the direct de-NOxing of ship exhaust gases is included in the overall consideration.

• Reduction of N2O emissions from wastewater treatment plants - measurements, modeling and process optimization (RENEMO)

  Recently, a more integrated view of greenhouse gas emissions from WWTPs has gained more and more attention. Preliminary studies indicated that apart from indirect emissions from electricity production the direct emissions of nitrous oxide (N2O) and methane (CH4) from biological processes at WWTPs might also play a major role in the CO2-footprint and should be included in life-cycle assessments. Lacking reliable scientific quantification of nitrous oxide from specific treatment processes, currently standard factors (developed by the IPCC) are used to estimate N2O emissions from municipal wastewater treatment plants for the National Greenhouse Gas Inventories required by the United Nations‟ Climate Convention and Kyoto Protocol. For this purpose it is important to close the current research gaps of reliable quantification of N2O and improving the understanding of the biological processes.
