Waste- and Circular Economy

  • TransMiT - Resource-optimised transformation of combined and separate drainage systems in existing quarters with high population pressure
    Increasing heavy rainfall events and growing urban quarters bring major challenges for urban drainage systems. The example of three districts in the cities of Braunschweig, Hanover and Hildesheim shows how urban planning and water management aspects can be linked in the long term.

Wastewater

  • AKIZ - Integrated Wastewater Concept for Industrial Zones (German-Vietnamese joint research project)
    Using containerized pilot plants for different branches in Tra Noc Industrial Zone, high-tech solutions for pre-treatment of wastewaters, generation of energy from wastewater and recuperation of valuable substances are adapted and verified by on-site pilot systems, taking into consideration the local conditions. Concepts for sewage sludge management are investigated. Monitoring surveys create the database for control mechanisms especially in terms of toxic wastewaters. Furthermore, sociological and ecological aspects are researched. The sustainable implementation of AKIZ shall be supported through capacity building for stakeholders and local partners.

  • 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.

  • 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.
